The Woosh Difference

Introducing the
Fit Tight System™

Built to eliminate leaks where ordinary filters fail.

Rigid Reusable Frame

Rigid frame prevents buckling, resists moisture, and is good for the life of your HVAC system.

Magnetic Seal Technology

Powerful magnets built into the rigid frame securely lock the filter and frame in place, allowing for quick and worry-free installation.

Pre-cut Adhesive Gaskets

Pre-cut adhesive gasket sealing the gap between a Woosh filter frame and the filter slot

Included pre-cut adhesive gaskets are easily applied to the rigid frame, filling any gaps that may still be present in the filter slot.

Designed for Easy, Dust-Free Disposal.

Customer Kevin O. holding his Woosh air filter
"Woosh caught an HVAC issue early, saving me from costly repairs. The system alerted me to abnormal pressure drops caused by frozen coils before any real damage was done. It’s like having a built-in technician tracking my system's performance!"
Kevin O., West Des Moines, IA
Customer holding a Woosh air filter next to a home furnace
We've had the Woosh air quality monitor in our living room and we used to manually kick the fan on/off to clean the air but now with the Sensi Smart Thermostat integration we don't have to, it’s all automatic. I'm excited to see this continue to grow and develop.
