Okay, so I've been using these Filterbuy filters for about 90 days now and here's the real tea ☕

First off - the fit is PERFECT. That slight size difference they mention? Genius move. Slides right in without that awkward wrestling match I used to have with other brands.

The air quality improvement was noticeable within like... 2 days? My allergies haven't been this chill since forever. Cat hair, dust, whatever - this thing catches it all.

Pro tip: Set up the subscription. Changed my life. No more 'oh crap I forgot to buy filters' moments at midnight.

Only weird thing - first package arrived looking like it went through a mosh pit. But their customer service hooked me up with replacements super fast.

Final verdict: 9.5/10 (taking off half a point for that packaging hiccup). Will absolutely keep buying!
