Buying Guide: Allergy Relief Without a Purifier
Keep these points in mind before you buy.
Control the source first
EPA advises source control and ventilation first. Encase mattresses and pillows, wash bedding hot weekly, vacuum with HEPA and keep humidity in check.
Upgrade the HVAC filter
A MERV 13 furnace filter cleans air for the whole home whenever the system fan runs. Check that your system can handle the higher rating.
Try a DIY box fan filter
A 20-inch box fan with a MERV 13 filter strapped to the intake is a low-cost room filter. Never leave it unattended and keep it away from water.

For pet dander
Pet dander is sticky and settles fast. Pair a HEPA purifier with a pet mode or pre-filter, and vacuum with a sealed HEPA vacuum to remove settled dander.
Damp-dust and wash weekly
Dust with a barely damp microfiber cloth so allergens are trapped, not spread, and wash bedding in hot water each week.
Source-Control Tips
Reduce allergens at the source:
- Encase mattress and pillows.
- Wash bedding hot weekly.
- Use a MERV 13 HVAC filter.
- Vacuum with sealed HEPA.
