LEVOIT Core Mini-P Replacement Filter, Genuine Core Mini-RF Air Purifier Filters, Supports HEPA Sleep Mode, High-Efficiency Activated Carbon for Removal of Smoke, Odor, Allergens, Pollen, 1 Pack,White

I use these for the little machine that's planted right next to my litterbox. I leave it on low for the most part but crank it up to high as needed - probably once a day for a few hours. They're not cheap but they remove some very foul odors (cat with GI problems) on the high setting in a pretty efficient manner, and they last six months to a year (whenever the indictor light comes on, but I can usually tell when they're becoming less effective). given how bad the smells are that it's working against, it's well worth the money.

once a month I purchase this product and I wouldn't change it for anything. its very efficient for the size. its super quite for the level of noise. it collects a lottttt of dust and durt. it hasn't given me any problems and I own 4 of them running constantly 24/7. the lifespan I would say if amazing. I've had mine for 3 going on 4 yrs now.

This is my second time using this replacement filter and it works great! We place our air filter in the living room and bedroom and one filter last me 4-5 months with no issues.

Great for desk or nightstand area filter try finding slightly damaged through Amazon resale for cheaper price on all the filters.

Works great in my son’s dorm room. Expensive replacement filter but worth it for how much dirt it removes from the air.

This works as it should since it’s the manufacturer filter but it is expensive.

I was a skeptic when I first bought the machine. Now I’m loving it and the filters honestly last for a long time.

Perfect fit. Easy to clean with handled vacuum for reuse
