Not sure which filter fits your Medify air purifier?
This detailed guide breaks down every Medify model—from the compact MA-14 to the powerhouse MA-112—and shows exactly which replacement filter you need.
Whether you're shopping for the first time or setting reminders for your next filter change, this guide makes it easy to match your machine with the right part so you keep breathing clean, purified air every day.
Why Filter Compatibility Matters
Choosing the correct replacement filter is key to keeping your Medify air purifier running at peak performance. Using the wrong filter can:
-
Lower your air purifier's efficiency
-
Void your warranty
-
Let allergens, smoke, and dust slip through
Each Medify purifier is designed with H13 or H14 True HEPA filtration, capable of removing up to 99.97% of airborne particles—but only when paired with its proper filter.
