QuietCool whole house fans use cooler outdoor air to efficiently cool and ventilate your home and attic. This not only fosters a healthier indoor environment but also significantly reduces energy usage, potentially saving you up to 50 to 90% on your A\/C-related electricity bills.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eFurthermore, QuietCool whole house fans greatly improve indoor air quality. By continuously swapping stale indoor air with fresh outdoor air, this fan helps remove pollutants, allergens, and other contaminants that can build up inside your home. It also helps prevent moisture buildup, reducing the risk of mold and mildew. When properly sized, the QuietCool can provide a complete air exchange every 3 to 4 minutes.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eEvery QuietCool RM whole house fan includes a three speed Electronically Commutated Motor, or ECM, that offers ultra-energy efficiency, included wireless controls, and an industry leading 15-year warranty.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003eThe \u003cb\u003eRM WHF-4.0-DB\u003c\/b\u003e is designed for homes with a sealed or conditioned attic, and a minimum of 36\" of clearance.\u003cbr\u003e\u003cbr\u003eThe \u003cb\u003eRM WHF-4.0-DG1 and DG2 \u003c\/b\u003emodels are designed for homes that have small, 6” or greater, rafter bays between the ceiling of the home and the roof.
