25 Replacement Filter for MA Series 25 S1/W1/B1 Air Purifier, 3-in-1 HEPA Activated Carbon Filter

These work well in my MA-25. The MA-25 is silent unless set on high speed. These filters do not change that. They do filter well.

These Hepa filters are very good filters at a good price

Fits perfectly

I bought this replacement filter thinking, "How exciting can clean air really be?" Turns out, VERY. This little marvel sucked up more dust than a bored Roomba on a mission. Within hours, my living room smelled less like "old gym sock meets wet dog" and more like "fresh alpine breeze with a hint of smug cleanliness." Installation was easier than assembling IKEA furniture (which is saying a lot), and now my air purifier is working harder than I do on Mondays. I swear I saw it wink at me in gratitude. Breathing has never been so luxurious. I now judge people based on the crispness of their indoor air. If you're wondering whether to buy this filter, just do it. Your lungs (and anyone with a nose within 20 feet of your home) will thank you.

These filters fit perfectly. They work great. Don't hesitate buy them. You will be glad you did. I'm very happy with the purshase. Great air flow.

It seems to work well, did have some smells that lingered

excellent quality, very prompt service, and fair price

they're air filters. it's kind of hard to mess that up.
