If you are on the hunt for info on a specific product; you’re in the right place. Below you’ll find a collection of purifier reviews that form the foundation of comparisons and guides you will find elsewhere on our site. Our objectives with these reviews are to simplify jargon and marketing terms while benchmarking products against their peers. However, our overall goal is to get as close to “apples to apples” as possible and help you make the best buying decision.
Our reviews are product specific and focus mostly on one product at a time. For topic focused comparisons (like the best air purifier for basements) check out our guides. They’re based on the reviews below but strive to answer a question… like which air purifier works best for smokers.
Our guides also cover product lines. For example if you want to see Honeywell’s air purifier lineup, you’ll find that in our selection of guides.
You’ve definitely seen 3M’s Post-it® notes … they’re a household name. You’ve probably even seen 3M’s Filtrete air filters. They’re probably the most common replacement air filter in both hardware stores and big box retailers. In fact, if you have a central air system in your home or office there’s a good chance that you have a 3M Filtrete filter right now.
What you might not see on a store shelf, however, is a 3M plug in air purifier. Shelf space is pretty limited in stores when it comes to air purifiers. But, you can get a 3M purifier online. And, with 3M’s stellar reputation for making great products you can breathe easy knowing that these purifiers are coming from one of the worlds premier companies.
Aeramax / Fellowes
Aeramax purifiers are part of the Fellowes Brands portfolio. You may know the Fellowes name if you work in an office or frequent office supply stores. The Fellowes family of products comprise a variety of office products from shredders, to laminators, to the seats in your cubicle. And, obviously they even make air purifiers. Aeramax
Airfree isn’t the biggest name in the purifier game, but they do bring an interesting approach to cleaning air. Without getting too deep into how they work we’ll just say that they use a patented heating system to kill organisms. It’s also unique in that it does not use a filter to mechanically separate pollutants from the air.
Airocide makes one of the coolest looking air purifiers out there. Like the Airfare above the Airocide is a filterless air purifier. It uses tech developed by NASA to improve air quality. Which in and of itself is pretty cool.
AIRMEGA, an offshoot of Coway, is one of our favorite purifier brands. They build purifiers that work incredibly well, look great, and offer the latest in smart tech. If you’re shopping for the best purifier out there AIRMEGA should be on your shortlist.
These guys make both ozone generators and air purifiers. Thier ozone machines are comparable to top tier in home units, and their air purifiers lean more toward the value priced end of the spectrum. Despite the budget pricing these purifiers look great and provide a fair value.
Alen is another of our favorites. They look amazing and work really, really well. Alen purifiers are a top tier brand so don’t expect to shop them against budget purifiers. Build quality, features, and design found in the Alen line is tough to beat.
Bissell is a household name, but their brand recognition is not attributed to their purifier offerings. In fact they’re a newcomer to air purification.
Blueair is a highly respected name in air purification. They’ve been on the business for a long time and build some of the most silent and most effective purifiers available. Blueair is a brand to consider when you’re shopping other leading brands like Alen, Rabbitair, AIRMEGA, etc.
Blue Pure is a new brand and line of purifiers offers by the highly regarded Blueair brand. These purifiers are more stylish, lower priced, and offer great features found in top tier machines.
A good way to judge a purifier review site is to look for a Coway recommendation. Their purifiers are some of the best performers you can find… and they’re reasonably priced. Coway isn’t new to the purifier business, but they aren’t up there in age with some competitors.
With that said we’re huge Coway fans. Both Coway branded purifiers and their higher end AIRMEGAS serve as benchmarks in the industry.
You’re probably familiar with Dyson’s vacuum cleaners, and perhaps their fans. But, they are also selling air purifiers these days. Are they worth the premium price tag? That’s debatable. But they are great looking, innovative, and work pretty well. If you’re a loyal Dyson fan… these are a great option. But, like thier vacuum cleaners… there are other options that may work better for some consumers.
Guardian’s Germ Guardian line is a hugely popular budget option. They work pretty well, but don’t expect them to be as effective as some review sites might lead you to believe. They’re a good purifier at a good price. But, to say that they’re the absolute best for any situation is quite a stretch.
Hamilton Beach makes a lot of appliances. From benders to waffle irons, crockpots to coffeemakers, and you guessed it – air purifiers. Their air purifier line isn’t huge, choices are pretty limited. It also skews toward the budget purifier end of the spectrum. We like them for very small spaces and tight budgets.
Holmes is another budget priced brand, that also happens to be pretty well represented in stores and homes across the country. Thier purifiers aren’t attractive, high tech, or ultra effective. But, they are a good value if money is tight and you want to improve the air quality in your home.
HoMedics is a mid priced purifier that is fairly popular with online retailers. They offer a variety of popular features and look pretty good.
Honeywell is a huge publicly traded company. They build aircraft components, have contracts with the military, and build some of the best bang for you buck air purifiers on the planet. Thier 50250-S purifier serves as a bit of a benchmark by which all other purifiers are judged. Surprisingly it lacks gadgetry and tech and instead offers some of the best filtration you can buy. We recommend looking at this purifier no matter what your budget may be. The 50250-S is perhaps the best example of how much purification you get per dollar with zero gimmicks, tech, or marketing lingo.
This is a premium, top-of-the-line purifier brand. IQAir is also a company that traces its purification roots back to the 1960’s. Their purifiers do not come cheap, but they work so well that they’re used in hospitals and are partnered with the American Lung Association. If you’re at all skeptical about air purifiers and demand top performance, IQAir has the track record and reputation to back up the price tag.
Levoit is one of our favorite budget priced, small format purifier brands. They make attractive purifiers that work well. While there are tons of higher performance purifiers out there, and plenty that offer up high tech features… we believe LEVOIT provides a great product for a great price.
Medify makes great looking purifiers that also rely on top tier HEPA filtration. They sit in the mid higher end of the pricing spectrum. They’re not as well known as some purifiers in their price range, but they’re definitely worth considering.
This company is perhaps the most strongly marketed purifier in the past 10-20 years. They carry a premium price tag, but promise to outperform the competition with the help of science. We’re not 100% sold that these are absolutely the best purifier out there, but we do respect that they back their claims with white papers and other established scientific principles. Oh and they are some of the coolest looking purifiers we’ve seen.
This company is a pretty widely known company that owes its recognition to products that suck. Yes, the famous vacuum company from the 80’s and 90’s also builds air purifiers. Like any product they have pros and cons. Feel free to read our reviews to get a better understanding of our opinion on Oreck’s purifier line.
Philips is another trusted name in the world of electronics and home appliances. They make great purifiers and they’re a big enough name to be held accountable if something goes south with their products. While the plugin purifiers are a great option… we’re partial to their car air purifiers. Which, are one of the few gimmick free products offered to those of us who travel by vehicle. We actually use both a Bosch HEPA cabin air filter and the Philips purifier in our personal vehicles.
RabbitAir is another one of the most respected names in the air purifier business. Like some of the others reviewed on our site you simply cannot go wrong with a Rabbit Air purifier. They focus on build quality, proven filtration methods, and avoid ridiculous gimmicks and marketing nonsense.
We’re fans of Venta. They’re not pretty… at all. They don’t have an app. And, they aren’t even sort of the best air purifier for most people. But, they do offer a product that few companies provide. Venta makes evaporative humidifiers that also capture particles from the air. It’s a combo that actually works and they’re by far the best humidifier / purifier combo machine.
Whirlpool is another home appliance company hoping to cash in on the popularity of air purifiers. They’re a large reputable company so that’s reassuring. But, they’re also not a huge player in the purification world. They make a very small number of purifiers and their a little overpriced if we’re being honest.
Winix is a purifier company that makes a good product for a good price. They’re typically comparable in price to a Honeywell product, but tend to skew a little more toward tech features and away from raw mechanical filtration.
