Homes are being more tightly built than ever before. Although this can make homes much more energy efficient, indoor air quality suffers when there is not adequate ventilation in the home.
Contaminants and airborne pollutants get trapped in the home, increasing in concentrations. Energy recovery ventilators (ERVs) are air exchangers that remove contaminated or stale air while simultaneously supplying fresh, filtered air. They are a great way to promote indoor air quality and energy efficiency in the home.
Heat Recovery Ventilators (HRV) are primarily used in cold or dry climates and can transfer heat from exhaust air to the intake air during the winter. Ideal for warmer, more humid climates with mild winters, ERVs transfer both moisture and heat from incoming fresh air to the outgoing airstream
Remove Pollutants with Filtered Air
Opening a window supplies fresh air into your house, but it isn't an energy efficient option for much of the year. This approach can also bring a lot of dust and pollen into the home, triggering asthma and allergy symptoms. ERVs filter incoming air from the outside, which aids in greater indoor air quality and overall health.
The Importance of Home Ventilation
Did you know that indoor airborne pollutant levels are commonly two to five times higher than outdoor levels, according to the US Environmental Protection Agency (EPA)? Many homes have bathroom exhaust fans and range hoods to remove excess humidity, fumes, and odors. Although this is adequate for some homes, this may not be an adequate ventilation strategy for tightly built homes or homes that have been air sealed.
This is because the home lacks gaps and cracks for air to flow between the interior and exterior of the home. ERVs offer an indoor air quality solution by constantly supplying fresh, filtered air into the home.
Greater Energy Efficiency
Energy and heat recovery ventilation systems promote energy savings and healthy air quality by transferring heat and moisture from the incoming fresh air stream to the outgoing air stream. This allows for efficient heating and cooling, makes good use of your energy dollars, and boosts home health.
