## Our score

- Score 4.8 out of 10
- Owners’ ratings, 40%: none yet at the shops that deliver to Germany, so this part is left out and the score is the features part alone.
- Features, 60%: 4.8, 29 of the 60 points for the maker’s and the registers’ facts.
- Price does not count, so a discount never lifts a model. Only air purifiers with a known CADR are ranked.
