Allergens that are embedded into furnishings or flooring are also not recorded by them.
In addition, the effectiveness of air purifiers in real-world scenarios most likely will not mimic those of controlled conditions in a laboratory (what those “99% efficiency” claims are describing!). The area, setup, circulation rate, and how long it is running for will all vary, as will the conditions in the area. In addition, there are other things occurring in your house that may 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 might have you think.

What should I search for in an air purifier?
CADR (clean-air shipment rate) rating. This measures the cleansing speed of the cleanser for removing smoke, dust, and and pollen. Look for a CADR of a minimum of 300, above 350 is really excellent.
For correct effectiveness, you need a design developed to operate in the space size. Pick a design that is created for an area larger than the one you are equipping it for if you want to operate it at a lower, quieter setting.

Keep in mind that there is no industry standard for the terms “HEPA-like” or “HEPA-type,” and are mostly utilized as marketing ploys to get customers to purchase the item.
