Enjoy fresh air with your furry friends with the Pet Care True HEPA Air Purifier. With its non-woven pre-filter, it captures more fur and pet dander. The activated carbon filter’s ARC Formula absorbs pet odors and chemically decomposes them to prevent second-hand pollution. The air purifier refreshes air 5 times per hour in rooms as large as 219 sq ft/20 sq m with its aerodynamic air duct design and spiral airflow.
