Lots of air purifiers are proficient at filtering toxin particles out of the air (dust, smoke, pollen, and so on), however they are not always very good at getting rid of gaseous contaminants like VOCs or radon from the air that may accumulate from adhesives, paints, or cleaning products. Allergens that are embedded into furnishings or floor covering are also not caught by them.

In addition, the effectiveness of air purifiers in real-world scenarios most likely will not simulate those of controlled conditions in a laboratory (what those “99% efficiency” claims are referring to!). The area, installation, circulation rate, and how long it is operating for will all differ, as will the conditions in the space. In addition, there are other things occurring in your home that might effect the effectiveness like ventilation (open or closed windows), and new particles are constantly emerging, so the air might not as filtered as the claims may have you think.

Utilizing neighboring wildfires as an example, Dr. Roten includes that a HEPA filter-equipped cleanser is your best bet: “Anything that has a real HEPA filter in it is most likely appropriate sufficient to filter out most all the large particles that would be worrying,” he states. “Most of the smoky smell will likewise be addressed too.”

What should I try to find in an air cleanser?

CADR (clean-air delivery rate) ranking. This measures the cleaning speed of the purifier for removing smoke, dust, and and pollen. Look for a CADR of a minimum of 300, above 350 is really great.

For correct efficacy, you require a design developed to operate in the room size. Select a design that is designed for a location larger than the one you are equipping it for if you wish to operate it at a lower, quieter setting.

Real HEPA. Real HEPA filters work at removing ultra fine particles (think: dust, dander, pollen, mold and other common allergens in the house). The market standard for such is that the unit should have the ability to get rid of at least 99.97% of particulates determining 0.3 micron size in a laboratory setting. Keep in mind, it is important to keep in mind that in real life settings, the real efficacy of these devices would be far less as new pollutants are constantly emerging. Keep in mind that there is no market standard for the terms “HEPA-like” or “HEPA-type,” and are primarily used as marketing tactics to get consumers to purchase the item.
