Kitchen range hoods and bathroom exhaust fans should be vented through the roof, not into the attic.

We often talk about the importance of “sealing the envelope” of your home. Improvements in building techniques and materials in recent years have resulted in homes today that are more tightly sealed than ever before.

While these advancements are great for saving energy and reducing your heating and cooling bills, they can also trap stale, polluted air inside your home.

That’s why it’s critical that your home is also well ventilated, allowing fresh air into the house and exhausting contaminated air to the outside.

Check out the Clear the Air episode to see how we solved a young family’s indoor air quality issues. And, watch Clearing the Air With Spot and Whole-House Ventilation for more information on improving indoor air quality.

And read this article until the end to learn the 9 Ways to Improve Your Home’s Indoor Air Quality!

Sources of Indoor Air Pollution

Lack of proper air exchange can cause the air in your home to be up to five times more polluted than outside air. This can cause increased problems in those with asthma or allergies, and can result other serious health risks. Common sources of home indoor air pollution include:

  • Dust, pet dander, and pollen
  • Excess moisture from bathing and cooking
  • Smoke and fumes from fireplaces, candles, tobacco, and gas appliances
  • Harmful volatile organic compounds (VOC) released by some cleaners, adhesives, paints, and other products
  • Radon gas that can be emitted naturally by the ground in certain areas

Whole-House Ventilation Systems

One of the biggest trends in creating healthy indoor air is whole-house ventilation. In fact, some states even require it, per indoor air quality building codes.

The new Fresh Air Systems from Broan offer one of the best solutions I’ve seen for creating and circulating clean air throughout the home. It runs both indoor and outdoor air through a core that filters impurities, and adjusts humidity and temperature. So no matter where your air is coming from, it’s constantly being purified, creating a healthier home and family.

There are two types of whole-house ventilation systems. Which one is right for your home depends on the climate where you live:

Heat Recovery Ventilators: HRV systems remove heat from the inside air before it’s exhausted to the outside, and use it to warm the incoming air. This makes them a good choice for colder climates.

Energy Recovery Ventilators: ERV systems manage both heat loss and the humidity in the air, making them ideal for warm, humid climates. An ERV system transfers some of the moisture in the humid air stream to the dryer air stream to recover the energy trapped in the moisture.
