The air surrounding our litterbox area is cleaner and fragrance-free. We don't even notice any odor at all, and it reduces dust. I've had my purrified unit for almost 3 years and love it. It's handy that all the components are replaceable either individually or as a kit. I'm glad the site offers cord protectors and different styles of mounts to accommodate our changing needs as our pets have changed guard and we have replaced out litterbox model. Thank you so so much for this quality, long-lasting, dependable filter.
Thank you for that wonderful review, RS.
