Best Air Purifier Reviews and Ratings

The Blueair Air Purifier 403 is a high end, energy efficient air cleaner that not only performs all the basic functions you would expect of arguably the best air purifier brand in terms of raw power, but performs them at an almost silent noise level. Indeed, unlike most of the air purifiers we have reviewed, the Blueair Air Purifier 403 makes virtually no sound as it processes your air up to 5 times an hour through its HEPASilent filter: So many brands claim to operate silently but it simply cannot be true for units in the low to medium price range. The Blueair Air Purifier 403, on the other hand, is a significantly more expensive air purifier, costing from two to three times the average, and the difference in price shows – whether it be the strong steel frame or the energy efficiency (this unit is Energy Star compliant) which will save you a lot of money in the long run.

Full features of the The Blueair Air Purifier 403 are:

• CADR value of 240 with maximum 365 square feet capacity
• Three speed settings for choice of intensity
• Strong, sturdy galvanized steel construction
• Energy Star compliant for cost savings on bills
• 5 purification cycles per hour

Average customer rating: 4.2/5 stars (based on total 11 air purifier ratings)

Despite its higher price, the Blueair Air Purifier 403 has received better average reviews than many of the far cheaper Honeywell air purifiers, which indicates that the Blueair Air Purifier may be the best air purifier out of them all, and may indeed be worth the higher price paid, since customers are happy with their purchase despite having paid significantly more. The positive Blueair Air 403 Air Purifier reviews are quick to point out the “very quiet” operating levels of the Blueair Air Purifier, even at the highest setting, so much so that getting to sleep and subsequently sleeping peacefully is not a problem with the unit turned on, something that cannot be said of less expensive air purifiers. Of course, as you would expect from a higher end product, the Blueair Air Purifier 403 does the job perfectly, removing dust, pollen and smoke from the air as well as anyone could expect from any air purifier, with a number of customers describing ultimate relief from their allergies as a result of using the Blueair Air Purifier 403.

Quite obviously, the main downside of the Blueair Air Purifier 403 is its price. At around $500 it represents a huge investment and is really only for those who are in real need of constant air purification, to the point that the extra money is worth the discomfort that a louder air purifier may cause, particularly at night when trying to get to sleep. Also, the whole design, both interior and exterior, is obviously more carefully and expertly designed, with better quality materials in almost every aspect of its composition. In addition to the significantly lower sound levels, the expert design also leads to much higher energy efficiency, and if you use an air purifier constantly or regularly, it may even be better in the long run to invest a little more now rather than face significantly higher bills that a lot of the cheaper, far less energy efficient air purifiers can sometimes give you. That being said, I personally don’t think $500 is justified unless you aren’t a very good sleeper and you need it to run 24/7 (or nearly that amount) in which case the Blueair Air Purifier 403 would be an intelligent option. Some other minor points: This unit is quite big, at 10 in. x 20 in. x 23 in. and weighing 40 lbs, it dwarfs some of the other air purifiers I’ve reviewed on this site so far, so this is certainly more of a permanent fixture in somebody’s bedroom, perhaps someone with severe allergies, rather than just a general, portable, once-in- a-while air purifier. Finally, the maximum room size of 365 square feet is deceptively average when you consider the overall size of the Blueair Air Purifier – I am often left wondering where all that size goes, but I would hazard a guess that the answer is a mixture between noise reduction and energy efficiency, the two main selling points of the Blueair Air Purifier 403. All in all, if you can afford it, definitely go for it, because aside from industrial units, the Blueair 403 is the best air purifier out there for the home.

The Honeywell 17000 has an average rating of 3.9/5 stars (from 176 total air purifier ratings)

All in all, customers are positive about the Honeywell HEPA Air Purifier 17000 though not quite as positive as those who have instead purchased the Winix PlasmaWave 5300, for example, with a 10% difference in total review score between them. Nonetheless, most customers who have got the Honeywell 17000 discuss their reasons for their purchase – mainly allergies and/or health reasons e.g. colds, flu etc., and then proceed to evaluate the Honeywell 17000′s performance in reducing symptoms. I’m pleased to report that the Honeywell HEPA Air Purifier 17000 seems to be performing very well in all areas: To quote the most helpful reviewer, [air purifiers] “really work!” following his experience with the Honeywell 17000. For the first time, he did not contract any kind of illness be it cold or the more severe flu over the winter. Moreover, he praises the Honeywell HEPA Air Purifier 17000 for its “whisper soft” low noise. Other people who bought the Honeywell 17000 mention the disappearance of coughs and allergies, the improvement of sleep quality and the feeling of the air being “crisp” after it has been filtered. To summarize, the Honeywell 17000 works very well, it’s not so expensive like some other air purifiers, it’s relatively quiet and the HEPA filter is permanent. All these lead to an overall very positive impression.

Most reviews online are in favor of the Honeywell HEPA Air Purifier 17000, however as always if you dig deep you can find a few complaints. I will now briefly air out (no pun intended) a few of the major drawbacks of the Honeywell 17000. The main thing I hear from most of the negative reviews is that the Honeywell HEPA Air Purifier 17000 is loud, which is quite strange as I hear the opposite from positive reviews. The only thing we can conclude from this is that the perception of sound level is very much subjective; what’s loud for one isn’t for another person, and vice versa. Frankly, if your air purifier is producing a noticeable sound, it is actually a sign that it is working. Sure, you can buy very quiet air cleaners for quite cheap, but they don’t truly filter your air. Inevitably, filtration leads to noise, however you sugar coat it. The second drawback of the Honeywell HEPA Air Purifier 17000 is that, while portable, the unit is rather big relative to other more powerful air purifiers on the market. With the size of it, you would think it could handle a room twice the volume of 12′ x 14′. Although the cost per cubic foot purified is decent, the size of the unit relative to one cubic foot purified is not so good. At the same time, we have to remember that the Honeywell HEPA Air Purifier does cost half that of most other air purifiers that you’ll see on Amazon, so it’s important to keep realistic expectations. Last but not least, there will be the added cost of replacing the carbon filter, which does a great job at removing odors and other pollutants, but it’s not so nice to have to spend a little extra cash every 6 months that you have to replace it. While the Honeywell 17000 is not necessarily the best air purifier of them all, it is the cheapest that Honeywell has to offer and thus gives more budget conscious consumers the chance to obtain quality air purification at a reasonable price.

The manufacturer of the Surround Air XJ-3800 Intelli-Pro Air Purifier makes the bold assertion that their latest purifier is superior to the best air purifier on Consumer Reports. The neutral reader would quite rightly be skeptical of such a claim; however, there is no denying that the Surround Air XJ-3800 Intelli-Pro Air Purifier is one of the top rated air purifiers on Amazon, coming second only to the positively fantastic Winix PlasmaWave 5300. With an astounding 7 step filtration process, the Surround Air XJ-3800 is ideal for people who want absolute perfection in the quality of air at home. Even the Winix PlasmaWave 5300 features “only” 3 steps of filtration. Although 7 steps may appear to be overkill for some, it is clear from the general consensus among the XJ-3800 Air Purifier ratings (in excess of 100 and counting) on Amazon that this technology works.

The Surround Air XJ-3800 Intelli-Pro Air Purifier has the following features:

• HEPA filter in addition to 6 other types of filter for maximum purification
• In-built sensor which monitors performance of the unit as well as current air quality
• Indicator lights to tell you when to replace the filters
• Low noise setting for peaceful operation

Customer rating: 4.3/5.0 stars (from a total of 101 XJ-3800 Air Purifier ratings)

As with some of the other best air purifiers out there, the Surround Air XJ-3800 Intelli-Pro Air Purifier has to its name a large number of aspects that have impressed its purchasers. Of course, having such a high average rating over a large number of reviews, we know very well that it works, but just how well does the Surround Air XJ-3800? Well, I can’t write any fair summary of the Surround Air XJ-3800 without mentioning one particular Surround Air XJ-3800 Air Purifier review from a guy called “Jimmy”, whose title is “Even detects a fart”! Apparently, he walked right in front of his second hand purchased Surround Air XJ-3800 Intelli-Pro Air Purifier and let one rip – and the odor detector light on the unit lit up! And as soon as the odor came, within seconds it was gone. If that’s not proof of top class functionality, well, I don’t know what is!

There are other slightly more technical Surround Air XJ-3800 Air Purifier reviews which tackle the main criteria of a good home air purifier, for example, the main thing that all people want to know before buying – how well does the Surround Air XJ-3800 Intelli-Pro Air Purifier remove smoke, pollen, smells, mold etc. from the air? The vast majority of customers expressed A+ quality (or its numerical equivalent 5/5 stars, 10/10, and so forth). The unit has also been described as the most complete air purifier in the sense that it removes the greatest variety of airbourne particles from the air, largely thanks to its comprehensive 7-filter core which surely leaves no stone unturned in terms of air purification. Next – and this was something that surprised me somewhat – some customers are reporting that the Surround Air XJ-3800 Intelli-Pro Air Purifier can successfully purify areas up to 1200 square feet despite the manufacturer’s listing it at 600 square feet maximum. As if the 600 square feet wasn’t excellent enough for the price, if such large capacity is true then the Surround Air XJ-3800 Intelli-Pro Air Purifier would represent by a long shot the best value home air purifier on the market.

It’s pretty much impossible to simply say “X is the best air purifier” or “Y is the worst” especially when it comes to appliances: Usually, each product simply has advantages and disadvantages. Some people won’t mind certain disadvantages and as such, the decision as to which air purifier to buy is often subjective. At the very least, I have filtered out (no pun intended) the lesser quality models and as such I only review the best air purifiers. The Surround Air XJ-3800 Intelli-Pro Air Purifier is indeed one of the best, but it is not without its own faults. For instance, many people will not want to buy an air purifier with an ionizer, despite the fact that it helps to remove large amounts of dust, because it emits small amounts of ozone, a gas which is not good for your health. In addition, some customers might not like the fact that this particular air purifier is made in China: While the overwhelming majority have had good experiences with the Surround Air XJ-3800 Intelli-Pro Air Purifier, there are a few who are not so happy with their China-made product. It’s my duty to warn you all, even if it turns out to be just a false alarm (damage in transit, anomaly, etc.). It’s always better to be safe than sorry, especially when your hard earned money is on the line!

If you decide that you would like a 600-1000 square feet air purifier for less than $200 and are prepared to buy a China made product for that large capacity, then the Surround Air XJ-3800 Intelli-Pro Air Purifier is the right one for you. If on the other hand you would much rather play it safe but perhaps only get half the maximum square feet coverage for the same price, then please browse our other air purifier reviews.

The Winix PlasmaWave 5300 Air Cleaner Model has established itself as one of the best air purifiers for those with allergies particularly sensitive to indoor air pollution. Whether it be pet-related dust and airbourne fur particles, smoke or most commonly, pollen, unpurified air can have a massive impact upon your health. The Winix PlasmaWave 5300 is a very reasonably priced, fully functional HEPA air purifier with an impressive CADR value of 280, which means it can purify rooms up to approximately 350 sq. ft. Even at full RRP, the Winix PlasmaWave 5300 thus represents significantly greater value based on the universal measure of maximum square foot purified per dollar. At the same time, the Winix PlasmaWave 5300 Air Cleaner Model has all the features of a top quality home air purifier, most notably a three stage filtration system to ensure purification is as complete as possible.

The Winix PlasmaWave 5300 has the following list of features:

• HEPA filter for successful removal of 99.97% of >3 microns airbourne particles
• Triple filter including carbon filter for pre-filtration and odor removal
• CADR: 280, maximum room size 350 sq. ft.
• Energy efficient for savings from your bills – Energy Star approved
• No ozone emitted, nor any other dangerous molecules
• 1 year limited warranty for added security

Customer rating: 4.4/5.0 stars (from a total 104 Winix Plasmawave 5300 Air Purifier ratings)

Although the Winix catalogue of air purifiers may not be as varied as that of Honeywell, it would be foolish to discard the Winix PlasmaWave 5300 simply on that basis, particularly because the average customer rating is around 10% higher than that of similarly priced Honeywell models. I personally was impressed by the sheer value packed into what is a relatively inexpensive air purifier: Indeed, the Winix PlasmaWave 5300 has all the features of $300+ air purifiers, but at a fraction of the cost. The CADR value at 280 is very respectable, which means that you can use the Winix PlasmaWave 5300 in rooms of area up to 350 square feet, and the automatically adjusting fan is a really nice touch – no more manually adjusting the unit – it simply changes according to the load. As you might expect from an item with such high average ratings, customers are overwhelmingly positive about the Winix PlasmaWave 5300: A few have listed the particular smells/indoor air pollution types that the Winix PlasmaWave 5300 Air Cleaner Model has successfully removed. It does seem that in addition to every single major indoor air pollutant, the Winix PlasmaWave 5300 can also make light work of odors, whether the smell comes from your pet(s), cooking or from smoking. This is no doubt a result of the carbon pre-filter which deals primarily with odors.

Whatever your reasons for purchasing an air purifier – dust, pollen or even general airbourne odor – the Winix PlasmaWave 5300 will solve it provided your room is below 400 square feet in area (20′ x 20′). The manufacturer states 350 square feet maximum but on turbo settings this unit can really move large amounts of air. For an air purifier under 200 dollars, that power is a fantastic quality. And judging by the nice feature on Amazon whereby customers can come back and edit/update their air purifier reviews years later if they so choose, the Winix PlasmaWave 5300 is not the type of appliance to last just a few months then break down. Numerous customer updates to their original air purifier ratings serve as reliable evidence that the Winix PlasmaWave 5300 is not only good quality when you first get it, but it will remain so for years.

While I do always endeavor to find as many negatives as I can with each item reviewed, it obviously becomes somewhat more difficult with the top rated items such as the Winix PlasmaWave 5300. But do not fear! I managed to find a few issues raised by one or two reviewers. Firstly, you will need to buy replacement filters every 6 months or so, which can cost around $40. Some – though by no means all – air purifiers do not require filters to be replaced, but note that this lack of requirement for replacements is often due to the fact that there are no extra filters in the first place. Purifiers like Winix PlasmaWave 5300 that use triple filtration technology are always more likely to require at least one filter to be replaced. Another negative that I have found is the Winix PlasmaWave 5300 Air Cleaner Model is noisy at the highest power setting. It’s difficult to compare the sound levels against other purifiers but some customers mention that the Winix PlasmaWave 5300 is actually quieter than the old air purifier they had, while somewhat louder than comparable Honeywell models. Finally, I really do think that the HEPA filter should be washable. One or two customers have raised this issue and I think that this is really the only major negative against the Winix PlasmaWave 5300 Air Cleaner Model.

Overall, if you are particularly sensitive to unclean air especially in terms of allergies, then the Winix Plasmawave 5300 is the best air purifier out there in the opinion of most consumers, with the highest rating of any air purifier reviewed on this site.

It is difficult to have a site dedicated to the best air purifiers without featuring a significant number of Honeywell air purifier reviews. After all, this is one of the most popular names in air purifiers nowadays. One of Honeywell’s latest models – the Honeywell HFD-120-Q – is a very affordable, sleek and stylish tower unit with >99.97% filtration capabilities and revolutionary ionizer which facilitates easy clean-up of free floating dust in the air. Despite its lower price among the many Honeywell air purifier reviews we offer on this site, the Honeywell HFD-120-Q can filter the entire variety of small particles that other top air purifiers remove, for example pollen, smoke, mold and much more.

The Honeywell HFD-120-Q has the following list of features:

• IFD filter, washable and permanent
• Indicator lights to notify you of requirement for washing
• Filters a large variety of particle types, including dust and pollen
• Ionizer which charges particles to stick to the ground for later vacuuming
• CADR: approximately 125, coverage 186 square feet

Customer rating: 3.9/5.0 stars (over a total 201 air purifier ratings)

Honeywell air purifier reviews wouldn’t be complete with a feature on the Honeywell HFD-120-Q, a very unique tower design and one of the cheapest air purifiers available that can do the job properly. While this particular air purifier from Honeywell has a very slightly lower average rating than other best air purifiers of the same brand, the Honeywell HFD-120-Q does have numerous advantages over its siblings. Reading the Honeywell air purifier reviews on Amazon and elsewhere online, it becomes clear that even the best air purifiers are quite loud and may interfere with sleeping, in particular. Thus, the first advantage of the Honeywell HFD-120-Q is that it is extremely quiet. Never underestimate this simple quality because when you get an air purifier, believe me, you will live with it for the rest of its days. The second major advantage of the Honeywell HFD-120-Q which I noticed after reading various Honeywell air purifier reviews was that some air purifiers have filters which need to be replaced: Even if the actual main HEPA filter itself doesn’t need to be replaced (only vacuumed/washed), there are parts such as carbon filters which do need to be replaced every 3-6 months or so, which of course costs money. You will find no such additional costs with the Honeywell HFD-120-Q. Moreover, and this is the third benefit to using the Honeywell HFD-120-Q over others – it is smaller and uses less power, therefore ongoing electricity costs will be lower, in addition to the initial significantly lower price.

Now, whether you read exclusively honeywell air purifier reviews or any other customer reviews of home appliances, there are always downsides associated with certain advantages. The Honeywell HFD-120-Q is no different. From the 200 plus Honeywell HFD-120-Q Air Purifier ratings on Amazon, it’s quite easy to deduce that this is a quality product that works, but that’s not to say things couldn’t be improved. First of all, the price is significantly lower (less than $150 at most good stores) than other top air purifiers, but the Honeywell HFD-120-Q also has a lot less air purifying capacity than more expensive models. Having a CADR of approximately 125, it can purify rooms of up to 186 square feet, that’s about 13.5′ x 13.5′ – anything over that and you need to look for a more powerful alternative. Anything at or below these dimensions, however, and the Honeywell HFD-120-Q is the best value option. Second, while it is indeed great that you don’t have to replace any filters, that is because as far as I can tell, there are no additional carbon filters, which can be quite useful as pre-filters particularly at removing unwanted odors from the air. If you really want carbon pre-filters, you may have to check out our other Honeywell air purifier reviews, because the Honeywell HFD-120-Q does not employ carbon pre-filters.

Overall, the Honeywell HFD-120-Q is the best air purifier for people with small rooms under 186 square feet, and who want the lowest price Honeywell air purifier that can purify their room effectively.

The Honeywell 50250 is one of the only air purifiers on the market under $200 that can purify rooms up to 390 square feet. From a cost perspective the Honeywell 50250 is the best air purifier for small to medium sized rooms as it represents some of the best value having a low cost:area purified ratio, and is covered by a 5 year limited warranty in case of any problems. Despite its lower price relative to other air purifiers with similar coverage, the Honeywell 50250 features all the functionalities you would expect from any leading air purifier, the only difference being in price. The Honeywell 50250 boasts a CADR (Clean Air Delivery Rate) of a very impressive 250 which allows it to compete with more expensive, high volume home air purifiers.

The Honeywell 50250 has the following features:

• True HEPA glass fiber filter
• CADR: 250
• Carbon pre-filter for removal of bad smells
• Indicator lights for quick alert filter change

Customer rating: 4.1/5.0 stars (based on a total 322 Honeywell 50250 Air Purifier ratings)

If your main priority is value, that is, getting the absolute best air purifier that actually works for the lowest possible cost, the Honeywell 50250 is probably your best bet. The good thing about the Honeywell 50250 is that it is made by a respected brand, kind of a specialist in the field of air purifiers these days, not to mention the fact that in spite of the price, the Honeywell 50250 can filter some pretty spacious rooms, up to 400 square feet. And that is where the main selling point of the Honeywell 50250 comes over others – even the (marginally superior) Whirlpool Whispure AP51030K – the Honeywell 50250 can handle a lot more air volume than similarly priced air purifiers, even from the same Honeywell brand. As one of the most helpful reviews on Amazon bears as its title, “Best Value Purifier”, I would be inclined to agree.

Aside from the good value, let’s now get into the specifics. What is making the people who own the Honeywell 50250 so positive about it? First of all, for its size, people seem to be impressed by the power of the unit. With a CADR value of 250, this little thing really does pack one heck of a punch. Second, maintenance is something that consumers are either going to be very impressed, or, alas, very annoyed by. Fortunately the the Honeywell 50250 Air Purifier reviews are once again positive about the relative lack of maintenance for the unit. The glass fiber HEPA filter, for example, the main component of the purification system, does not need to be replaced, ever. As for the other parts, if any replacements do occasionally have to be sourced, carbon pre-filters for example, the Honeywell 50250 is so popular and the Honeywell brand so specialized in air purification units that such parts are very easy to find and very cheap. Third, a nice little feature which many would overlook particularly those who have not before owned an air purifier, is the 360 in and output of air, so that there isn’t a lone gust in one single direction. Finally, the Honeywell 50250 Air Purifier reviews on Amazon indicate that customers have had good experiences with the Honeywell customer support, and this is vital given that you have a 5 year limited warranty and will possibly need their help at some point in the future.

Seeing as there are over 300 total Honeywell 50250 Air Purifier ratings, there are bound to be some negative aspects raised by current owners of the unit. The main negative I am reading most often is the sound levels. You would think for such a modest sized air purifier it would be reasonably quiet, but the 250 CADR power seems to shine through, for better or worse. Nonetheless the sound isn’t so bad – it’s not the terribly bothersome rattle and buzz of a loud washing machine, it’s more like a swift breeze. Other customers are complaining about how the Honeywell 50250 looks. I cannot refute this: it doesn’t exactly look pretty, but then again what air purifier does? Finally, your electricity bill is something that you will have to monitor: At its highest fan speed, the Honeywell 50250 consumes 170 W. At this highest fan speed, the Honeywell 50250 will cost $150 per year if you run it 24/7, though at its lowest fan speed it will cost less than $50 which is not bad at all. Moral of the story: Ask hospitals, operating rooms and top corporate offices – the best air purifier system doesn’t come cheap, whoever you are.

Such functions include sensors which detect when the filter needs to be replaced, carbon pre-filter, and convenient electronic controls.

This honeywell air purifier has the following features:

• CADR: 150

Customer rating: 4/5 stars (over a total 178 air purifier ratings)

Honeywell air purifiers need no introduction: This is probably the most well known, well respected manufacturer of home air purifiers to date. It’s very easy to decide on an item based on its brand alone, but this review will take this particular honeywell air purifier, the Honeywell 18155 SilentComfort, as an individual unit. Although Honeywell is respected, I urge new buyers of air purifiers not to buy a honeywell air purifier simply because it is Honeywell. Read as many air purifier reviews as you can, check out air purifier ratings on sites like consumer reports as much as you can before buying anything. I know it’s boring but do a bit of research and you will save yourself a lot of money; this applies to all types of products, not just air purifiers.

The Honeywell Air Purifier 18155 SilentComfort is the best air purifier for people who need it for a small to mid size room, and who are looking to get a high quality air purifier at a reasonable price. The CADR is 150, therefore the maximum recommended area which this honeywell air purifier can cover is approximately 225 square feet. If you have a larger room than this (15′ x 15′), then please continue to browse our reviews – at the moment I would recommend the Whirlpool Whispure AP51030K which covers rooms of around 21′ x 21′. Also, if you are unsure as to what I mean by CADR, please read our page on CADR as it is very important for your best air purifier search – trust me, it will save you a lot of money.

As for specific features of the Honeywell Air Purifier 18155 SilentComfort, customers describe it as quiet, and even on high setting about as loud as a dishwasher from the room nextdoor. In terms of the air quality, most people who have written 18155 Honeywell Air Purifier reviews on Amazon are very happy with the removal of particles from the air, the removal of odors as well (due to the carbon filter, no doubt), as well as the dramatic stopping of allergies when the Honeywell Air Purifier 18155 is in operation. This Honeywell air purifier does not have an ionizer which many people might favor due to ionizers’ emitting ozone (O3) which is said to be harmful to the lungs in certain quantities, however in defence of other air purifiers which do in fact have ionizers, I am sure that if any appliance were dangerous it would not be allowed to go on the market. Finally, owners of this Honeywell air purifier seem to like the way in which the unit blows the purified air out – not too fast, not too slow; a gentle, comforting breeze as one person put it. There’s no mechanical buzzing or any sort of discomforting sounds while in operation; these things are great to know, thank goodness for the internet, as there is nothing worse than buying an item only to find out that it makes a terrible sound when it is on. (A slight digression here: My thanks to all reviewers on Amazon, consumer reports and elsewhere – I hope to provide as much help as you have given me.)

I can, as per usual, find some bad experiences, though they are, admittedly, in the minority. We have the typical experiences of non-functional units, the sudden stopping of functionality which is all too indicative of a power outage and the subsequent surge of power (my educated guess, as always). One customer was not happy that the buttons were too far indented so you had to make an effort to press down, though I haven’t managed to find this complaint from anyone else. Another negative in my view is that the CADR of this Honeywell air purifier is only 150 which means you will be able to purify a room of total 225 square feet. This is a moderately sized area but could be bigger. Note that the Whirlpool Whispure AP51030K can handle around 450 square feet. However for the Honeywell air purifier 225 square feet is not necessarily a bad value given the price. (This Honeywell Air Purifier 18155 is priced at $200 compared to $350 for the Whirlpool Whispure.)

Overall, if you’ve got a small-medium sized room below 225 square feet (15′ x 15′) and you want the quality of the Honeywell brand, but you don’t want to pay the often astronomical costs for a high end, high CADR Honeywell air purifier, then the Honeywell Air Purifier 18155 SilentComfort is the ideal choice. If you’ve got a room bigger than 225 square feet (yes, get out your measuring tape!) then please continue to read the air purifier reviews on this site.

Many of the Whirlpool AP51030K Air Purifier reviews are quick to note that this unit has been voted the best air purifier of the year 2010, and the rating of 92% (4.6 stars from 5) on Amazon is an indication of the converging opinions of both Amazon and consumer reports users. It should give the average person seeking an effective, reliable air purifier a lot more confidence to see that the opinion is near universal (a true indicator of a top quality product). There was a Hunter brand unit that shared the top rated crown for 2010, but unfortunately that model has been discontinued. As for Honeywell – often the most popular brand when it comes to air purifiers – it seems that Whirlpool has done just as well, if not better. While Whirlpool may not specialize in air purifiers as does Honeywell, the Whirlpool AP51030K shows no signs of lack of focus, in fact quite the opposite.

Despite the slightly above average size, the customers who have written the Whirlpool AP51030K Air Purifier reviews on Amazon are pleased with features such as simple yet very plentiful controls giving lots of options, including fan speed which is quite nice as some people can tolerate more fan noise than others. Not that the Whirlpool AP51030K is especially loud, in fact, personally I find it slightly quieter than average, but a fan is a fan and especially running at the very powerful ‘turbo’ mode, it’s not going to be silent! Customers are also pleased by the indicators that let you know when you need to replace the filter, but not only that, it lets you know how much ‘life’ it has got left which is a nice little touch. People who have bought the Whirlpool AP51030K feel a lot more secure with the 5 year warranty, although I must remark that it is limited.

As for the all important factor, the quality of air post Whirlpool AP51030K, well, the general consensus is that the air feels a lot more clean, fresh, the smell is improved, and all visible dust/dirt/other particles are removed by this unit. Some reviewers have even gone on to order more of these units, despite the additional cost, simply due to the health benefits they have received. It certainly is not within our best interests to sit indoors all day, be it at the office or at home, breathing in dirty air.

Although the negatives of the Whirlpool AP51030K are few, I did find one or two. First of all, in addition to the initial investment on the actual Whirlpool AP51030K unit, using this regularly will lead to an increase of around $10 per month on your electricity bill. Some reviewers have 4 air purifiers in the house, adding nearly $50 to their monthly electricity bill, which is a massive amount if you think about it. However, if you stick to just one, $10 per month is manageable. When they work well, as the Whirlpool AP51030K invariably does, air purifiers are miraculous things, but make no mistake – they do require a fair bit of power. Other minor issues include high noise reported by one customer, though others claim it is the quietest air purifier available, and excessively bright LEDs which make it difficult to go to sleep when the unit is turned on. If that’s the extent of the Whirlpool AP51030K’s problems, however, I can definitely live with that!
