A single-room H13 True HEPA unit that covers a bedroom or home office. The easiest first step if you want to see whether filtration actually changes your symptoms before committing to a whole-home system.
The next generation of the AP-1512HH, the unit that spent years as the default recommendation in this category. True HEPA plus activated carbon, sized for a living room rather than a single bedroom.
A 4-stage steel-cased unit built around a large-capacity HEPA and activated carbon/zeolite bed, rated for continuous whole-room operation. This is the tier to look at if filtration is medically necessary rather than optional.
Your HVAC system already moves every cubic foot of air in the house. Upgrading the return filter to MERV 13 captures pollen, pet dander and fine dust system-wide, and costs a fraction of a standalone purifier.
Dust mites live in the mattress, not the air, so no purifier reaches them. A fully zippered encasement is the one intervention that physically separates you from the reservoir for a third of every day.
A sealed HEPA system matters more than suction here. A vacuum that filters its own exhaust removes settled dander instead of re-aerosolising it into the room you just cleaned.
