9 Best Air purifiers Of 2020 can save you from COVID-19 infection
1. Effective, Efficient. Coway AP-1512HH Mighty
Effective, efficient, and inexpensive The Coway Mighty is the right size for master bedrooms, playrooms, and living rooms—and it’s one of the best-performing, most durable, and most economical purifiers we’ve ever tested.
Within 30 minutes, the Cоwау AP-1512HH Mightу reduced heavy smoke роllutiоn in a 135-square-foot, 1,215-сubiс-fооt New Yоrk office bу аѕ much аѕ 98.9 реrсеnt. In past tеѕtѕ, it performed еԛuаllу wеll in a 200-ѕԛuаrе-fооt, 1,600-сubiс-fооt New Yоrk City bеdrооm. And whеn wе tеѕtеd it during оngоing ѕmоkе conditions in a vаѕt Lоѕ Angеlеѕ соnfеrеnсе rооm of nеаrlу 10,000 сubiс fееt—mоrе thаn twice аѕ lаrgе as thе Coway Mightу’ѕ ѕресѕ wоuld ѕееminglу аllоw—it cut раrtiсulаtе роllutiоn by almost 70 percent in аn hоur. In short:
It’s a fantastic рurifiеr on реrfоrmаnсе аlоnе. But that’s not thе оnlу rеаѕоn it’ѕ оur pick. At an uр-frоnt рriсе that оftеn lаndѕ undеr $200, аnd at аn аvеrаgе total соѕt оf about $450 fоr fivе years оf ореrаtiоn (inсluding the bаѕе рriсе, annual rерlасеmеnt filtеrѕ, аnd еlесtriсitу), it’s easily the most affordable Air Purifier of its abilities that we’ve еvеr found. Itѕ compact fоrm, quiet ореrаtiоn, аnd diѕрlау-ѕhutоff fеаturе (ѕо it wоn’t disturb ѕlеер with bright lightѕ) mаkе it еѕресiаllу well suited tо bedrooms. Finаllу, thе Cоwау Mightу maintains itѕ exceptional реrfоrmаnсе оvеr thе lоng term: Wе’vе rереаtеdlу mеаѕurеd itѕ performance using filtеrѕ thаt hаvе been in соntinuоuѕ uѕе 24/7 fоr a year оr more, аnd every time it has cleaned thе аir juѕt as wеll аѕ it hаѕ with brаnd-nеw filtеrѕ.
2. Alen BreatheSmart Classic Large Room Air Purifier
Do you have a big home? Not a problem with the Alen BreatheSmart Classic Large Room Air Purifier. This best air purifier of 2020 cleans up to 1100 sq. ft. every 30 minutes without filling your house with noise. In fact, the technology is twice as quiet as that of its key competitors, even on Turbo speed. Like all high-quality air purifiers, the Alen BeatheSmart has a HEP-Pure filter that claims to capture 99 percent of airborne particles down to 0.3 microns. This combines with the device’s Laser Smart Sensor, which also detects airborne particles down to 0.3 microns, to effectively clean your air of dust, pollen, allergens and dander.
No expense is spared in the design of the air purifier, either. The Air Quality Indicator Light always reflects the real-time purity of the room’s air in an easy-to-read display. Furthermore, it comes in 14 different colors and panels so you can always find one to match your home’s interior. This is a high-end device, coming in at $688.
3. A stellar performer for larger rooms Blueair Blue Pure 211+
The Blue Pure 211+ aced our tests, and its ability to move extremely high volumes of air make it our pick for large spaces.
The Blueair Blue Pure 211+ is our choice among air purifiers for large spaces of up to 650 square feet, especially spaces with open floor plans or high ceilings. With the ability to filter more air per hour than our top pick, the Coway Mighty, it works faster to achieve and maintain low particulate levels in such challenging rooms. The up-front price and running costs of the Blue Pure 211+ are higher than those of the Coway Mighty (totaling about $800 versus $450 over five years), but it’s far less expensive than most other large-space purifiers we’ve looked at. It was an exceptional performer in our testing, and it’s quiet and attractive to boot. All that said, unless you really need to clean a particularly large space, the quieter, smaller, and more affordable Coway Mighty is usually a better option.
4. Levoit Compact Air Purifier
Compact enough to fit on your desk but powerful enough to remove 99.9 percent of dust, pollen, smoke, odor, mold spores and pet dander, the Levoit Compact Air Purifier is an excellent entry-level option. Rather than using a UV or ions to clean the air, the device features a three-stage filtration system. This comprises a pre-filter, a HEPA filter and an activated carbon filter. Three fan settings let you control the speed and volume of the purifier.
This air purifier was definitely designed for use in the bedroom, but you can also tuck it into the corner of your desk at work. It features a soft optional night light with two brightness settings as well as a very quiet fan. It’s not out of place on your nightstand, with its white or black case and sleek design. While not as feature-filled as other air purifiers on this list and better suited to small rooms than large homes, you can find it on Amazon for the low price of $90.
5. Small, effective, and attractive Blueair Blue Pure 411
In a small bedroom, dorm room, or office, the diminutive and affordable Blue Pure 411 performs well and looks great.
If you need to clean the air in only a small space—a bedroom, nursery, or dorm room, up to about 150 square feet—the Blueair Blue Pure 411 is a solid, inexpensive, and energy-efficient purifier. In such spaces, it performs impressively: In our tests, it reduced particulates by more than 87 percent on its high setting in 30 minutes in a 135-square-foot New York City office. It’s also attractive, with a simple cylindrical design and five color options, and it’s compact, measuring just 16½ inches tall and 7½ inches in diameter. At around $120 to purchase and about $220 total to run for five years (thanks to excellent energy efficiency and inexpensive replacement filters), it’s the cheapest of all our picks. But we found that it didn’t keep pace with the Coway Mighty and the Blue Pure 211+ in larger rooms.
6. Honeywell True HEPA Allergen Air Purifier
Honeywell air purifiers have been recommended by allergists time and time again, and for good reason. This air purifier is excellent at ensuring that allergens — whether they be from pollen, pet dander, or anything else — are taken out of the air. That’s perfect for those with allergies. The device also offers three air cleaning levels, along with a Turbo Clean setting, and it can circulate the air in a home up to a whopping five times per hour. That’s impressive.
7. For odors and chemical sensitivity Austin Air HealthMate HM400
While this model’s HEPA filter removes particulates (like pollen and smoke) from the air, its second filter efficiently removes odors and toxic gases—something our other picks don’t do well
If your environment has high levels of both particulates and volatile organic compounds (VOCs, or more broadly, odors), we recommend the Austin Air HealthMate HM400. Its massive 15-pound VOC filter bested all others we tested by a wide margin, and its HEPA filter offered excellent performance on particulates. The Austin Air’s performance comes at a price, however: Costing about $500 to $600 up front, and averaging around $1,300 for five years of use, it’s the most expensive machine we recommend. You could buy and run three Coway AP-1512HH Mighty purifiers for about the same cost, and if particulates are your main concern, doing that instead will let you remove particulates from more rooms and a larger overall area.
8. PARTU Best Air Purifiers of 2020
The PARTU Air Purifier claims to be the quietest on the market, which is big news for anyone who’s struggled to sleep to do a whirring, noisy fan. At its lowest speed, the PARTU creates 25db of noise; this is just above the sound of leaves rustling, which clocks in at 20db, for comparison. A fairly basic device, its most notable features are a multicolor light setting and a memory function that remembers your last chosen setting when you turn it on.
This isn’t the most stylish air purifier of the bunch; guests will definitely know its purpose when they walk in the room. But it’s still relatively compact at 17 inches in height, making it easy to stow away, and is the least expensive in-home device of the pack at $70.
9. Dyson Pure Cool Link Desk Air Purifier
Dyson has long been known as an innovator in the home cleaning space, though its product line recently evolved beyond vacuums to include technology like purifying fans. The Dyson Pure Cool Fans come in two sizes: a tower and a smaller desktop size. The Desk Air Purifier earns its spot on this list because it’s significantly less expensive than its larger counterpart — though at $400, it’s still an investment. We’ve recently seen it on sale for as low as $270 on Amazon, however, so keep your eyes peeled.
Inside the fan itself is a Dyson HEPA filter, complete with a layer of activated carbon granules that capture odors and harmful toxins like paint fumes. But the real appeal of this product is its portable size. At just 25 inches tall, it fits neatly into small spaces like laundry rooms and home offices where a stand-up fan might be cumbersome.
What can an air purifier do for you?
Air purifiers do one thing and do it very well: remove fine particles from the air. They are especially good at rapidly filtering out the most common airborne allergens, including dust and pollen; mold, mildew, and fungal spores; pet dander; dust mites and their excrement; soot from automobiles; and tobacco, marijuana, and wildfire smoke. HEPA purifiers also capture many airborne pathogens, including most bacteria and viruses. For a detailed discussion of their potential impact on the COVID-19 coronavirus, see the following section.
Air purifier owners offer extensive, almost universal testimony that the machines improve their sleep, reduce their allergies, or lessen their asthma symptoms, and recent studies have begun investigating an association between particulate pollution and degenerative brain disorders, including Alzheimer’s disease and Parkinson’s disease. Air pollution from US combustion emissions alone results in 200,000 premature deaths a year, according to a 2013 MIT study.
However, in the US air purifiers cannot be marketed as medical devices. That’s because it is exceptionally difficult to disentangle the known air-quality impacts listed above from other environmental and genetic factors that influence health.
HEPA (high-efficiency particulate air) filters don’t capture volatile organic compounds (VOCs, or more broadly, odors and fumes). To reduce them you need significant amounts of an adsorbent (typically activated charcoal, which chemically binds to and immobilizes the VOCs) and/or a class of minerals known as zeolites, whose extremely fine pores allow them to function as molecular filters.
No air purifier can do anything about allergens, bacteria, or viruses that have settled on furniture and other surfaces. To remove allergens like pet hair and pollen, you’ll need a vacuum cleaner To get rid of viruses and bacteria.
Can HEPA Air Purifiers Capture COVID-19 Infection
Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the coronavirus that causes COVID-19, and many of you have asked whether air purifiers can help protect against infection. The answer is yes in theory. The CDC believes the virus is mainly transmitted by person-to-person contact, but there is growing evidence that it may also be transmitted through the air. If that is confirmed to be the case, HEPA filters will capture airborne coronaviruses.
The virus that causes COVID-19 is approximately 0.125 micron (125 nanometers) in diameter. That falls squarely within the particle-size range that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above. Many media outlets have incorrectly stated that HEPA filters don’t filter below 0.3 micron, and therefore could not capture airborne coronavirus. That is flat wrong. (This NASA study of HEPA filtration is quite technical, but the graph on page 7 and the preceding paragraph do a good job of explaining why HEPA filters are actually most efficient—almost 100 percent at 0.01 micron—at capturing ultrafine particles below the 0.3 micron HEPA test standard.)
But that doesn’t mean an air purifier will protect you, because it’s not certain that the virus can survive and remain infectious in the air. The position taken both by the CDC and by other global health agencies is that the coronavirus is primarily transmitted by person-to-person contact and by contact with virus-laden droplets expelled by coughing and sneezing. Sneezes and coughs certainly suggest “airborne” to most of us, but the droplets only travel about 6 feet before dropping out of the air and settling on surfaces. This is one reason health agencies worldwide are recommending 6-foot/2-meter “social distancing,” and related efforts like frequent hand washing and disinfection of surfaces, as the primary means of protecting yourself.
It’s also the reason HEPA purifiers must not be considered a first line of defense against the COVID-19 virus. “The big thing with trying to say that a HEPA filter would do any good is whether you’re getting anything to the filter or not,” said Kathleen Owen, a consulting engineer with nearly 40 years’ experience in air filtration. “If it turns out—and this is the big if; I’m not sure you should even mention it—but if there’s stuff that’s getting into the air, HEPA would catch it.”
Owen noted that the coronavirus that caused the SARS outbreak in 2003 was primarily transmitted person-to-person, but is thought to possibly have been airborne as well. Research into whether the COVID-19 virus can spread via the air—meaning whether it can float around for hours, travel long distances, and remain infectious—is ongoing. An April 2 article from Nature provides an excellent summary of the studies done to date, and makes clear that there is no consensus one way or the other. However, a committee from the National Academy of Sciences has told the White House that it believes the evidence points to airborne transmission.
Until that becomes the CDC’s official position, we recommend you continue to follow the CDC’s best practices, including social distancing, wearing a mask outdoors, washing your hands frequently, and treating frequently touched surfaces with commonly sold (or homemade) disinfectants that are effective on coronavirus.
