Many air purifiers perform well out of the box—but are they a worthy investment over time? Data from CR’s air purifier survey can help answer that question.
We recently collected info on more than 40,000 air purifiers purchased between 2015 and 2025 by CR members and analyzed that data to determine how models from 50 different brands tend to perform in the years that followed. The results, which are factored into a product’s Overall Score, suggest that some air purifier brands indeed outpace others in predicted reliability and owner satisfaction.

Most Reliable Air Purifier Brands
Given an air purifier’s dependable design, it’s not surprising that a little more than half of the brands in our ratings—33 out of 50—receive favorable ratings for predicted reliability. And yet, some brands truly excel in this arena, while at least one received a reliability rating so low that we can’t recommend the models it makes. For air purifiers, our reliability scores indicate the likelihood of encountering problems with your device by the end of the fifth year of ownership.
