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
