    • Cleans up dust and allergens
Color: grey
Great replacement filter for my Mi Air purifier! The triple-layer design with activated carbon really helps with dust, allergens, and odors. Easy to install and lasts a long time. The air feels noticeably cleaner—definitely worth it!

    • Good Quality Filter.

Works just as described. No increased noise and good quality for the price.

    • Authentic
Color: grey
It resets my air purifier, so I believe it is genuine. It would have been preferable if it had been a "True" HEPA filter for extra air filtration

    • OEM filter. Fits exactly like original.
Color: grey
Filter seems to be original and has the "RFID" chip on the bottom so didn't have to reset anything on the 3H. Kinda wish it was packed a little better (arrived in original box), but it arrived ok.

This air purifier filter is very easy to install and has a nice packaging but after a few weeks of using it starts to smell like cheese does anyone know a fix to this?
