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. 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 than outside your home. 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

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. Moisture is added to your home's air throughout the day by showering, laundry, or washing the dishes. This added moisture creates an environment where viruses, bacteria, molds and dust mites thrive. Highly humid air can also damage your home by causing the wood to swell, warp, or even rot. Ventilation helps circulate this air.

Do’s & Don'ts


consider the size of your home and its location when installing a ventilation system

Larger homes and extreme climates may cause your ventilation system to work inefficiently. If you live in a larger home and/or an extreme climate, you may want to look into an energy-efficient system that will help you maintain indoor air quality and save you money.


frequently clean out dryer vents to maintain constant ventilation

In fact, you may also want to consider using more eco-friendly and plant-based 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 poor 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 you are releasing Volatile Organic Compounds (VOCs) in the air. Make sure your home's air is properly ventilated to keep VOCs manageable.  

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. By helping your home better, you're helping your family breathe better.
