For example, our #1-selling Austin Air Healthmate utilizes a HEPA filter along with a thick bed of activated carbon to help eliminate dust, pollen, and dander as well as things like smoke, odors, and chemical vapors. HEPA air purifiers are the most popular, and they are perfect for eliminating household allergens such as dust, animal dander, pollen, and other particulate. First is their patented hemispheric HEPA-type filter, which removes dust, smoke, and pollen from the air.

That’s where an air purifier comes in: Air purifiers filter out airborne allergens, which include dust mites, mold spores and pet dander,” says Devang Doshi, M.D., the Director of Pediatric Allergy and Immunology at Beaumont Hospital in Royal Oak, Michigan. Air purifiers use different kinds of filters to do their job – usually, a large washable, reusable pre-filter to collect the large particles, plus a finer filter, which is usually a disposable HEPA (High Efficiency Particulate Air) filter. This huge combination filter catches virtually every airborne contaminant down to a virus in size: pollen, dust, pet dander, mold spores, allergens and bacteria.
This combination filter catches virtually every airborne contaminant down to a virus in size: pollen, dust, pet dander, mold spores, allergens and bacteria. HEPA filters trap 99.97% of particles down to3 microns in size, reducing the airborne allergens in your home. The air purifier simply won’t be powerful enough to quickly and effectively remove pollutants, such as pollen, dust, smoke and pet dander, from the air.
Its four-stage hospital-style HEPA antimicrobial filter is capable of removing most airborne particles, including pollen, dust mites and cigarette smoke and it couldn’t be easier to use. Via its app – the same one used to control the Dyson 360 Eye robot vac – you can set how sensitive to particles you are (if you want your air perfectly clean at all times, expect to see that £50 filter longevity head south to 180 days), set timers, and monitor your room’s air quality and temperature, as well as the pollen and pollution counts in your local area. These units are also called air cleaners – their purpose is to remove pollutants and allergens from the air in your home using filters.
HEPA filtration is a physical process: A fan running at high speed draws particles suspended in the air through a dense, feltlike filter with gaps of varying size. With a Clean Air Delivery Rate (CADR) of 350 cfm on high for smoke, pollen, and dust, it handily outdraws most purifiers in its price range and many machines that cost far more. 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.
For example, an air purifier with a CADR like this: dust/500 cfm, pollen/640 cfm, and smoke/500 cfm (or 500 Dust/500 Smoke/640 Pollen) will normally have a coverage from 700 to 800 square feet. Its True HEPA filter meets the strictly standards to remove 99.97% of dust, smoke, odor, mold spores, pet dander and particles as small as 0.3 microns. Some air cleaner models offer optional filters for smoke and odors, but these simply trap chemicals and odor vapors in activated charcoal or carbon, and are not very effective unless they have a sizeable carbon, like in the Airpura models.
Cost per square foot of filtration with a HEPA unit ranges from35 cents to as much as $1.10 (or more); filter-less air purifiers units average18 -25 cents per square foot (not including electricity costs). Consequently, most filtration-type air cleaners (they are NOT air purifiers because the cannot purify the ambient air of very small contaminants like viruses!) have large, often loud fans because they only clean the air they can actually filter through them. In order to clean the air, these appliances use filters and fans to remove particles and circulate the purified air back into the room.
HEPA technology is used in portable air purifiers as it removes common airborne allergens. It uses True HEPA technology which captures 99.97 % of airborne pollutants including pet dander, pollen, and dust mights as well as other particles. This air purifier captures 99% of airborne pollutants including mold, dust, pet dander, pollen, and smoke.
This air purifier covers an area of up to 150 – 200 sq ft. Ionizer, HEPA filter and activated carbon filter is included in the multi-filtration technology of this air purifier. Many filters are designed for mimicking the effectiveness of HEPA filtration, but very few of them achieve the ability to remove particles down to 0.1 microns in size or smaller. The air purifiers efficiently remove harmful gases, bacteria, pollen, virus, ultra-fine particles and dust.
Allergies: If you have allergies, you should choose an air purifier designed for allergy relief They typically have multiple filters, including HEPA filters, to remove indoor allergens. If you’re looking for general air quality improvements, consider models with HEPA filters, or High Efficiency Particulate Air filters, which are proven to eliminate 99.97% of common airborne allergens sized at 0.3 microns and larger. These air purifiers feature the technology to detect and report real time air quality levels, purifying your air while acting as a fan at the same time.
Our air purifiers are specifically designed to remove germs and airborne allergens like dust, mould spores and pollen so you can breathe easy and sleep better. The HEPA filter is a mechanical air filter and it’s a way of purifying the air is by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. Using the Blueair HEPASilent Technology, the purifier removes all the airborne pollutants ensuring superior quality of air to the users.
The purifier comes with Vitashield IPS technology which can remove particles of up to 0.02-micron size which is more than 100 times smaller than the normal PM 2.5. With its numerical indicator and 4 color AQI lights, the purifier provides the real-time PM levels in the air. The HEPA removes airborne allergens such as dust, pollen, mold, viruses, and bacteria. Smart Air recommends the standard HEPA filters they provide be changed within less than 2 months when operating 24 hours a day, while the long-life true HEPA filters in the more expensive air-purifiers, when combined with activated carbon and pre-filters, only need to be changed once every 2-5 years according to their manufacturers.
HEPA filters are no good where dust has settled, since the filters can remove only airborne particles. All of the air purifiers we’ve tested here use a HEPA filter, which will capture a minimum of 99.97% of airborne particles 0.3µm in size. Air purifiers use a fan to pull in dirty air at one end, remove pollutants, and output clean air at the other end.
Cut down on pollen, smoke, dust and make your home environment full of clean air with Trusted Reviews’ ranking of the best air purifiers, all fully tested. The Whispure’s Clean Air Delivery Rate (CADR) is the highest of any air purifier we’ve tested here at TopTenReviews, meaning that it removes smoke, dust, pollen and more from indoor air with ease. Filters: 2 – carbon filter, True HEPA filter Ionizer: N Auto mode: N Max power use: 102W Noise: 55.1 dB Warranty: 5 years CADR: pollen removal – 401, dust – 325, smoke – 316 Coverage (sq ft): 490.
Most air purifiers tackle these particles with a pre-filter, which also helps protect the more delicate inner filters, but the Winix HR900 has two prefilters including an Ultimate Pet Pre-filter for an extra layer of protection against pet-related dust and dirt.
