MOOKA Air Purifiers for Home Large Room up to 1076ft², H13 True HEPA Air Filter Cleaner, Odor Eliminator, Remove Smoke Dust Pollen Pet Dander, Night Light, B-D02L White

We have 3 air purifiers: 1 in the living room (main floor) 1 in our bedroom (top floor) and 1 in a spare room (top floor, where 1 of 2 litter boxes is). We scoop the litters once a day. They're stainless steel so they don't absorb odor like the plastic ones do. Adding the air purifiers made a big difference in the "cat box smell." Before, you could walk into our home and think Ah, cats live here and now you can walk in and be like Oh! You have cats?!? This is the one we bought 3 of, and the replacement filters are pretty inexpensive too https://amzn.to/4ogYKs7 Edited to add the litterboxes that we have https://amzn.to/4fAZmXn
