A purifier with genuine MERV-13 filtration captures airborne pollen (a relatively large, easily-filtered particle), lowering the amount you breathe indoors. Sufferers most often notice a difference overnight in the bedroom.
What they can't do
They don't stop pollen you carry in on clothes and hair, and they only clean air they reach — so placement and sizing matter, and they work best alongside shut windows and showering after being out.
Getting it right
Prioritise the bedroom, size to the room (calculator), and run it continuously through the season. See the full setup guide.
