FAQs

The ranking is based on aggregated user sentiment from Reddit. The ranking algorithm takes into account 1) the ratio of positive to negative user sentiment, and 2) the volume of user sentiments.


The intention is to show which Air Purifiers are the most well reviewed.


Green = no. of users who expressed sentiment.

Orange = no. of users who expressed neutral sentiment.

Red = no. of users who expressed negative sentiment.


Details on the ranking algorithm:

For each model we calculate the normalized difference between the number of positive and negative user sentiments, and the normalized ratio betweeen the number of positive and negative user sentiments. We then weight the absolute difference slightly more heavily than the ratio (0.6 vs 0.4) to determine the final score for ranking.

Our data includes Reddit comments and posts from the last 1.5 years, as of 6/25/2025, to keep rankings fresh and relevant.

We continuously crawl Reddit for discussions on Air Purifiers across all subreddits. Each comment and post is analyzed to identify specific Air Purifiers models and brands, and then a sentiment analysis is performed to gauge user satisfaction.

Our rankings shows the most popular, well-reviewed Air Purifiers among Reddit users. It is a good starting point for finding the best Air Purifiers for you, especially if you're looking for tried-and-tested ones. However, individual needs vary, so the best model depends on what you're looking for.

Reddit has an exceptionally strong strong community and moderation. Because of that Reddit is one of the last bastions of genuine online discussions. That makes Reddit a great source for real, unbiased opinions from everyday users. That's why so many people include "Reddit" in their Google searches.
