CRW SH-GBD-8F Glassbrudd


Air Quality Sensor


SH-AQ enables you to take control of home air quality. Indoor air quality is affected by smoke and volatile organic chemicals (VOCs). Home building materials and furniture may also release these VOCs. In the process of trying to secure your home by locking doors and keeping the windows shut you may inadvertently seal in carbon dioxide. Furnaces and other wood-fueled heaters also produce carbon monoxide while high humidity contributes to poor air quality.
