HED: Indoor Air Quality

Breathe easier, feel warmer, and reduce indoor air pollution.

A healthy building is one that can breathe.

Over the last 20 years, changes in building practices encouraged energy saving, Our well-insulated homes and offices have trapped harmful pollutants, which in some cases, put you and your family at risk, particularly those who suffer from allergies or lowered immune systems.


Today, we recognize the importance of indoor air quality, (or IAQ). Engineers, scientists and industry experts have developed innovative solutions — air cleaners and ERV (Energy Recovery Ventilators) that remove allergy-aggravating particles and harmful ozone from indoor air and converts it into clean, healthy oxygen.

Maintaining a proper humidity level throughout your home and workplace also contributes to a comfortable, healthy space to live and work. Indoor humidity levels should be between 30 and 50 percent with the ideal — about 45 percent relative humidity.

As with Indoor Air Quality, newer, energy-efficient homes tend to fall victim to problems of high humidity more often. Because these homes are sealed up tight to prevent energy loss from heating and cooling, the house also seals in a lot of moisture. Without adequate ventilation and maintenance of relative humidity, you can create an environment that could be friendly to mold growth.
