First off, let’s talk value—getting TWO H13 True HEPA filters in this pack felt like stumbling upon a hidden discount. I’ve been using these in my Medify MA-40 purifier for weeks, and honestly? They perform identically to the OEM filters but cost way less. Snaps right in with zero gaps, just like the original.

The 3-stage filtration is no joke. My apartment reeked of last night’s fish fry, but after an hour on high speed? Gone. The activated carbon layer murders odors—I even tested it near my cat’s litter box (risky move) and it handled the ammonia smell impressively.

Dust bunny alert: The pre-filter catches visible debris like a champ. I’ve got long hair and a shedding dog, so finding less fur swirling around my floors was an instant win. Airflow feels strong too—no weird whistling or reduced performance like some knockoffs.

One heads-up: These don’t come with a change reminder sticker (unlike Medify’s originals), so set a phone alert for that 4-5 month replacement window. But at this price? I’ll gladly trade a sticker for extra savings.

Final verdict? If your MA-40 is wheezing for fresh filters, this 2-pack is the stealth MVP—affordable, effective, and surprisingly premium for a compatible product.
