Feeling a bit sneazy inside? Partner starting to smell? Live in a place with no open windows? Not sure of the latest results but the 5 stage topped Choice's 2020 test and highly in the 2021 testing (as well as the 4 stage). The Philips 3000i scored a tad better as well as the higher priced InovaAir E20 Plus.
I can personally vouch for the 5 Stage. It is simple but works well for large areas and is quiet. Comes with a 12 pack of pet filters to keep you going.

Best price at the moment but not best drop in history (missed the nice Nov drop). Looking at CCC I'd envisage that these might even drop further soon.
One of this (5-stage) or 2xPhilips 1000 which are also on offer so I could use one upstairs and one downstairs?
