Updated on:

At Modern Castle we assess air purifiers with a series of objective and data-driven tests. We focus on ozone generation, coverage levels, noise, usability, and air purification performance, which is our most important factor. We gather this data through a battery of tests and assessments to determine the best air purifiers.

Below you can see a complete list of all air purifiers we’ve tested to date.
