How We Chose the Best Alternative to Air Purifier Filter
To choose the best alternative to air purifier filter, we compared popular HEPA, carbon, pre-filter and MERV 13 HVAC filters on Amazon by filter type, rated life, fit and owner feedback.
EPA says to match CADR to room size, use activated carbon for gases and choose at least MERV 13 for HVAC filters where the system allows; see the EPA Guide to Air Cleaners in the Home.
Product details in this guide are based on manufacturer specifications and verified owner feedback. Read more on our How We Test page.
Buying Guide: Choosing an Alternative
Keep these points in mind before you buy.
MERV 13 for the HVAC
EPA suggests a furnace or HVAC filter rated at least MERV 13, or as high as your system can handle. HVAC filters only work while the system runs, often less than 25% of the time in heating and cooling seasons.
Box fan setups are a stopgap
A box fan with a 20×20 MERV 13 filter is not a tested air purifier; follow the fan maker’s safety guidance and never leave it unattended.
Skip ozone
EPA advises avoiding air cleaners that intentionally produce ozone, a lung irritant.
Source Control Tips
Fewer pollutants to filter:
- Ventilate with clean outdoor air.
- Use exhaust fans.
- Fix moisture to stop mold.
- Avoid indoor smoking.
