For hay fever, the best air purifier is simply one that keeps pollen out of the room you sleep and relax in, quietly enough to run all season. Here's what to prioritise. For symptoms and medication, see the hay fever resource.

Pollen is a relatively large particle that MERV-13 captures easily — so you don't need an exotic filter, just a genuine one. Avoid low-grade washable filters.
The right size, quiet enough to leave on
The bedroom is the priority room. Choose a unit sized for it (see the CADR guide) that runs quietly — ideally under 35 dB — so you leave it on all night, when relief matters most.
Set-up for pollen season
Run it continuously through the season, keep windows shut on high-pollen days, and change filters more often in summer as they load faster with pollen.
