Do Air Purifiers Actually Work?

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

How do air purifiers work?

Air purifiers typically consist of a filter, or numerous filters, and a fan that sucks in and distributes air.

As air moves through the filter, contaminants and particles are captured and the clean air is pushed back out into the home. Usually, filters are made from paper, fiber (often fiberglass), or mesh, and require routine replacement to maintain performance.

What are air purifiers expected to filter out and do they really do it?

Most filters on the marketplace are created to capture particles like dust and pollen, but don’t catch gases like VOCs (volatile natural compounds) or radon. That would need an adsorbent, like activated carbon. In fact, the Epa (EPA) cautions that the functionality of air cleansers is limited in regards to straining gases, and that you must regularly change filters for ideal performance, typically about every three or so months.

Many air cleansers are good at filtering toxin particles out of the air (dust, smoke, pollen, etc.), however they are not always excellent at eliminating gaseous pollutants like VOCs or radon from the air that may accumulate from adhesives, paints, or cleaning products. Irritants that are embedded into furniture or floor covering are also not recorded by them.

In addition, the efficiency of air purifiers in real-world circumstances likely will not mimic those of controlled conditions in a lab (what those “99% efficiency” claims are describing!). The location, setup, flow rate, and 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 continuously emerging, so the air may not as filtered as the claims may have you think.

If you are concerned about mold, we ‘d recommend purchasing a dehumidifier or humidifier to help keep the appropriate moisture levels in your home and stave off mold growth problems. Air purifiers do not avoid mold growth, so it is necessary to remove the source of wetness that is enabling it to grow.

Can air purifiers filter the outdoor air that enters your home?

Sometimes, non-organic air pollutants like the VOCs we mentioned formerly can stem from outdoors your home. “There are all sorts of scenarios in structure fires where big dosages of smoke inhalation may cause cyanide toxicity. That would mainly require to be someone who was standing directly in or near the fire: Those individuals are brought to emergency spaces immediately,” Dr. Roten describes. “Typically, outside contamination or smoke or temporary bad air isn’t a consistent concern for spectators.” The right kind of purifier can deal with any environmental air qualities in your location. Using nearby wildfires as an example, Dr. Roten includes that a HEPA filter-equipped purifier is your best choice: “Anything that has a real HEPA filter in it is probably sufficient enough to filter out a lot of all the large particles that would be concerning,” he states. “Most of the smoky odor will also be addressed as well.”

What should I look for in an air purifier?

CADR (clean-air delivery rate) score. This determines the cleaning speed of the cleanser for eliminating smoke, dust, and and pollen. Try to find a CADR of at least 300, above 350 is actually excellent.

For correct effectiveness, you require a design developed to operate in the room size. Choose a design that is developed for an area larger than the one you are outfitting it for if you wish to operate it at a lower, quieter setting.

AHAM (Association of Home Home Appliance Manufacturers) Verified mark AHAM’s requirements are style to ensure the security, efficiency and performance of lots of house care appliances, including air purifiers. The standards are designed to provide a common understanding between manufacturers and consumers to help make the buying process simpler. While voluntary, most respectable air cleansers have actually undergone this accreditation program, which frequently supplies a CADR rating and size guidelines.

Real HEPA. Real HEPA filters work at eliminating ultra fine particles (think: dust, dander, pollen, mold and other common irritants in the house). The market requirement for such is that the unit needs to be able to eliminate a minimum of 99.97% of particulates determining 0.3 micron diameter in a lab setting. Remember, it is important to keep in mind that in real life settings, the real efficacy of these gadgets would be far less as new pollutants are constantly emerging. Note that there is no market standard for the terms “HEPA-like” or “HEPA-type,” and are mainly used as marketing ploys to get customers to buy the item.
