Do Air Purifiers Really Work?

Professionals weighs in on whether or not purifiers can truly filter out germs, dust, smoke, mold, and more.

How do air cleansers work?

Air cleansers usually include a filter, or numerous filters, and a fan that absorbs and distributes air.

As air moves through the filter, pollutants and particles are captured and the clean air is pushed back out into the home. Normally, filters are made of paper, fiber (often fiberglass), or mesh, and need regular replacement to preserve efficiency.


The majority of filters on the market are developed to record particles like dust and pollen, but don’t catch gases like VOCs (unstable natural compounds) or radon. That would require an adsorbent, like triggered carbon. The Environmental Security Company (EPA) warns that the performance of air cleansers is restricted in terms of filtering out gases, and that you should frequently change filters for optimal functionality, typically about every 3 or so months.

Numerous air cleansers are proficient at filtering pollutant particles out of the air (dust, smoke, pollen, etc.), but they are not always excellent at getting rid of gaseous contaminants like VOCs or radon from the air that may build up from adhesives, paints, or cleaning items. Allergens that are embedded into furnishings or floor covering are likewise not captured by them.

Furthermore, the efficiency of air cleansers in real-world scenarios likely will not mimic those of regulated conditions in a lab (what those “99% effectiveness” claims are referring to!). The location, setup, circulation rate, and for how long it is operating for will all vary, as will the conditions in the space. In addition, there are other things happening in your house that might effect the efficacy like ventilation (open or closed windows), and brand-new particles are constantly emerging, so the air might not as filtered as the claims may have you think.

If you are worried about mold, we ‘d recommend purchasing a dehumidifier or humidifier to help maintain the suitable wetness levels in your house and stave off mold development problems. Air cleansers do not avoid mold development, so it is needed to remove the source of moisture that is allowing it to grow.

Can air cleansers filter the outdoor air that enters your house?

Often, non-organic air contaminants like the VOCs we pointed out previously can originate from outdoors your house. “There are all sorts of situations in structure fires where big doses of smoke inhalation may lead to cyanide toxicity. However that would mainly need to be somebody who was standing directly in or near the fire: Those people are brought to emergency rooms right away,” Dr. Roten explains. “Normally, outside contamination or smoke or short-term bad air isn’t a continuous concern for spectators.” However the best kind of purifier can resolve any environmental air qualities in your area. Utilizing nearby wildfires as an example, Dr. Roten includes that a HEPA filter-equipped purifier is your best option: “Anything that has a real HEPA filter in it is most likely adequate sufficient to filter out many all the large particles that would be worrying,” he says. “The majority of the smoky odor will also be attended to also.”

What should I look for in an air purifier?

CADR (clean-air shipment rate) ranking. This measures the cleaning speed of the purifier for removing smoke, dust, and and pollen. Search for a CADR of at least 300, above 350 is really fantastic.

For appropriate effectiveness, you need a design created to work in the space size. Pick a design that is created for a location larger than the one you are outfitting it for if you want to run it at a lower, quieter setting.

AHAM (Association of House Device Manufacturers) Verified mark AHAM’s standards are design to ensure the safety, effectiveness and performance of lots of home care home appliances, including air cleansers. The standards are designed to provide a common understanding in between manufacturers and consumers to help make the getting process easier. While voluntary, the majority of trusted air purifiers have actually undergone this certification program, which typically provides a CADR score and size standards.

True HEPA. Real HEPA filters work at removing ultra fine particles (think: dust, dander, pollen, mold and other typical irritants in the home). The industry standard for such is that the unit should be able to get rid of a minimum of 99.97% of particulates measuring 0.3 micron diameter in a lab setting. Keep in mind, it is important to note that in real life settings, the actual effectiveness of these gadgets would be far less as brand-new contaminants are continuously emerging. Keep in mind that there is no market requirement for the terms “HEPA-like” or “HEPA-type,” and are mostly used as marketing ploys to get customers to acquire the item.
