As Seen On Shark Tank | 16x25x1 4-Pack MERV 8 Air Filter

The Woosh Smart-Ready 4-Pack Starter Kit replaces flimsy cardboard filters with a rigid reusable frame. Powerful integrated magnets and custom gasketing create a "perfect seal" to eliminate air bypass, while the 4 included high-performance MERV 8 refills effortlessly trap dust and allergens. Best of all, the future-proof Smart-Ready design allows you to seamlessly plug in smart sensors later to monitor your filter life and HVAC system automatically.
