Intended for homeowners who want to pull more conditioned air into cool or hot rooms without changing ductwork, the unit quietly boosts airflow by up to 85% and can deliver as much as 132 CFM at its highest setting. The included 6-ft power cord and plug-in design make installation straightforward, and the patented smart technology automatically turns the fan on and off with the HVAC system, so it requires minimal interaction once in place.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoosted airflow:\u003c\/strong\u003e Increases airflow to under-served rooms by up to 85%, helping rooms reach the set temperature faster.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable speed:\u003c\/strong\u003e Five adjustable fan speeds let users tailor airflow up to a maximum of 132 CFM for comfort and balance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-quiet operation:\u003c\/strong\u003e Engineered and assembled in the USA to minimize noise so the fan can run without drawing attention.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy installation:\u003c\/strong\u003e Fits standard 4' x 10' floor or wall registers and requires no tools - just plug the 6-ft cord into a nearby outlet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart auto on\/off:\u003c\/strong\u003e Patented technology senses when the HVAC is running and switches the booster on or off automatically.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrusted build:\u003c\/strong\u003e Backed by a 12 month warranty and decades of brand experience for reliable performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe booster fan is best for homeowners or renters with specific rooms that consistently feel too hot or too cold and where adjusting vents or the thermostat has not solved the issue.
