Frequently asked
What filter fits a Medify MA-22 air purifier?
The Medify MA-22 uses the AXPPF231 (AIRx Replacement HEPA Filter for Medify MA-22).
Is the AXPPF231 True HEPA?
Yes - the AXPPF231 is a True HEPA filter, rated H13, meaning it's rated to capture at least 99.97% of 0.3-micron particles.
How often should I replace the AXPPF231?
About every 6 months under typical use, or sooner if airflow drops or your purifier's filter indicator lights up.
Should I buy the OEM filter or an aftermarket one?
The genuine Medify AXPPF231 is the safe, exact-fit choice. A cheaper aftermarket filter can fit the same slot too - check reviews for real-world fit and filtration performance before buying, since air purifier filters generally aren't independently certified the way NSF-listed water filters are.
