FAQs
The ranking is based on aggregated user sentiment from Reddit. It aims to show which Air Purifiers are the most well reviewed.
Ranking factors:
- The number of positive user sentiments
- The ratio of positive to negative user sentiment
- How specific the user was in their reference to the model
Scoring mechanism:
- Each user contributes up to 1 "vote" per model, regardless of no. of comments on it.
- A user's vote is less than 1 if the user does not specify the exact model - their 1 vote is "spread out" among the possible models.
- More popular models are given more weight (to account for the higher likelihood that they are the model being referred to).
Score calculation for ranking:
- We combine the normalized positive sentiment score and the normalized positive:negative ratio (weighted 75%-25%)
- This score is used to rank the Air Purifiers in descending order
Our data includes Reddit comments and posts from the past 1 year from 11/21/2025, 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.
