Stop fighting over the thermostat. DraftFix clips onto any 4x10 or 4x12 floor/wall register and actively pushes air into the rooms your HVAC system leaves behind — no more freezing bedrooms or roasting home offices. Built-in thermostat control automatically ramps the fan up or down to hold your target temp, and the included remote lets you adjust speed and mode from across the room. Quiet, easy 2-minute install, no tools or ductwork required.
