Review on Innofresh Fridge-It- Refrigerator Deodorizer & Odor Absorber - 1 Pack, Wafer Size. Natural Activated Charcoal, Fragrance-Free Formula, Long-Lasting up to 4 Months by Susan Vaughn

I have two cats and their litter boxes are in the laundry room, which has no windows or air conditioning, so it can get quite smelly. Even though I clean the trays every day, the smell comes from the laundry room door. I have tried several other odor removal products with no success. I found Innofresh Pet Odor Eliminator and used four of them for two months but it didn't eliminate the odor completely. I finally tried one of these Innofresh fridge odor absorbers and within 24 hours the smell was 99% gone! I didn't even empty one of the toilets for a whole week just to check but the smell was gone anyway! I doubt it will last the advertised 4 months but finally no litter box smell when I walk past the laundry, worth buying one every month or two!
