Zehnder Comfosystems - Comfort Ventilation Systems

As homes are becoming more tightly built, proper ventilation is increasingly critical for optimal indoor air quality. A constant supply of fresh filtered air in the indoor spaces in which we spend more than 70% of our time is vital to our health. Zehnder Comfosystems comfort ventilation systems provide an assurance that equal amounts of stale and fresh air will be exchanged and optimal indoor air quality is achieved in the home.

Fresh air promotes well-being and a healthy lifestyle. Poor indoor air quality can lead to a rise in asthma and allergic symptoms due to the increased concentration of allergens such as dust mites, VOCs, pollen and mold. Zehnders comfort ventilation systems offer optional fine filters which capture fine dust and pollen, even allergy sufferers can breathe easily.
