Shopping Guide and Advisor

What attributes matter when choosing the best air purifier?

Type of Filter

A filter is the most significant part of an air purifier. Therefore, when looking for an air cleaner, ensure you pick a high-quality filter. HEPA is the most common filter, which removes dust and pollutants of up to 0.3 microns. While it works in eliminating allergens, it does not remove strong smells. You will need an activated carbon filter for that. Reading air purifier reviews and doing analysis will help you get an excellent purifier.


Certification ensures a high-performance standard. When looking into certification for air purifiers, you should consider the AHAM and the China certifications. Any model with certification has undergone inspection and a test run. You can read the air purifier reviews to confirm this.


An Air purifier’s performance is measured by the CADR (clean air delivery rate), ACH (air changes per hour), and the size of the room it can purify. A tested purifier should filter the air in a place several times in an hour. It ensures a fresh supply of air at all times.

How does an air purifier work?

An air purifier has internal fans that pull in the interior air and runs it through several filters. The dust particles, pet dander, hairs, smoke, and other allergens are trapped in the filter. The clean air flows into the room. The process repeats every few minutes to ensure the air in the house is always fresh.
