Think of your home’s ventilation system as an intricate set of lungs – it helps your healthy home inhale the good and exhale the bad, leading to greater indoor air quality. In fact, according to the Environmental Protection Agency, ventilation systems reduce the concentration of pollutants in your home, which can be 2-5 times greater inside your home than outside. These pollutants, such as dust, molds and allergens can have an effect on your family’s overall respiratory health.

Ventilation Systems Help Reduce:

  • Dust and Dust Mites
  • Pollen
  • Pet Dander
  • Mold Spores
  • Gases, Chemicals and Smoke
  • Misc. Air Particles

It’s obviously important to ensure your healthy home is properly sealed, which only increases the need for a highly efficient ventilation system. When you seal your home, you’re preventing drafts from entering or exiting your home, which can save you tons of money in energy costs each year. However, without ventilation, your tightly sealed home is subject to stale, stagnant, polluted air. This is where your ventilation system shines as it pumps the bad air out and the good air in, improving airflow and circulation.


Ventilation also lends a hand in removing moisture from your home. Every time your family showers, does laundry, or runs the dishwasher – or if you simply live in a particularly humid climate – moisture is added to the air. This can affect your family’s health by providing a climate where viruses, bacteria, molds and dust mites thrive. Not to mention, highly humid air can cause damage to your home by causing wood to swell, warp or even rot. Ventilation helps circulate this air, providing better indoor air quality, and therefore, a healthy home.

Do’s & Don'ts


consider the size of your home as well as the climate it’s located in when installing a ventilation system

Larger homes and extreme climates may cause your ventilation system to work harder. If that’s the case, you may want to look into an energy efficient system that will help maintain indoor air quality and help save you money year-round.


clean out dryer vents frequently to maintain constant ventilation

In fact, you may also want to consider using less toxic laundry solutions. Anytime you smell that “fresh laundry” smell, your family is inhaling chemicals. Consider using less volatile cleaning products at home like this DIY fabric softener to increase indoor air quality.


forget to test your home for radon

Radon is the second leading cause of lung cancer. According to the American Lung Association, concentrations of radon can increase in homes with low ventilation. If radon levels are high in your home, hire a professional to help remove it as soon as possible.


make sure gas, propane and wood smoke ventilate outdoors

It’s important to minimize the source of indoor air pollutants in your home. Forcing these pollutants to ventilate outdoors provides greater indoor air quality for you and your family.


forget to install smoke and carbon monoxide detectors throughout your home

A great ventilation system should help maintain a healthy home, but it will not help in emergency situations. Take every precaution.


open windows and use a fan to add extra ventilation

Whenever painting, gluing or using excess amounts of cleaning supplies.

Like the lungs, homes need to be able to breathe to make sure that fresh air comes in and dirty air goes out.”

American Lung Association


As we mention above, your home’s ventilation system is like an intricate set of lungs. By properly ventilating your home, you’re filling it with fresh, breathable air while simultaneously maintaining airflow and removing harmful indoor air pollutants. Help your family breathe better by helping your home breathe better.
