This is a really, really key question that not enough people ask.
First, remember how air purifiers work.
The purifier’s fan circulates air around a room, pulling the air and airborne allergens towards the unit. The fan ultimately pulls the air directly through the unit where the filter captures the allergens. The resulting stream of pure air is returned into the room.

3. Run It 24/7 for Maximum Effectiveness
That’s right, don’t think about it, just run it!Air purifiers are most effective when they are in constant use. And if you are worried about energy consumption, see our page on Energy Star rated units. Air is always moving. Our testing has shown that a clean room can go back to being full of pollutants in as little as an hour! The coverage area rating for each unit is also calculated with this idea in mind, so keep it on and you’ll get the best possible resu
