More than ever before, homes are being more tightly built to promote energy efficiency. As a result, less air is exchanged between the interior and exterior of these tightly built homes causing high humidity levels inside these air tight spaces. This highly humid environment can encourage mold growth and indoor pollutant levels, and can create a humidity level inside that might be two to five times higher than it is outdoors. This can be compromising to the homeowners’ health in many cases.Therefore, proper ventilation to remove moisture, fumes, odors, and air pollutants, and to provide a constant supply of fresh air, is increasingly critical for homeowners health in these types of homes.

Zehnder Comfosystems heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) ensure that equal amounts of stale air and fresh air are exchanged for optimal indoor air quality throughout the home. The air coming in from the outside is filtered, removing many common pollutants and airborne allergens. As the most energy-efficient HRV systems on the market, Comfosystems are up to 95% effective in recycling heat from the exhaust air to the supply  air while promoting indoor air quality in tightly built homes.
