How we test

01Three weeks per deviceEach model runs continuously in a real home in the Montréal area, in the dead of winter.

03Real 3-year costPurchase price, replacement filters and electricity: we calculate what you will really pay.

Frequently asked questions

What size purifier should I choose?+

Aim for a device whose rated area exceeds your room by at least 30%: manufacturers test in ideal conditions.

Should it run continuously?+

Yes, ideally in automatic mode. A purifier only acts on the air that passes through it; turning it off quickly cancels the benefit.

Does a purifier replace an air exchanger?+

No. It filters particles but does not renew air or control humidity. The two are complementary.
