Think of your home’s ventilation system as an intricate set of lungs—it helps your home inhale good air and exhale bad air. Today’s tightly-constructed homes are being built to keep heated or cooled air in, which is great for lowering energy costs but tends to trap air pollution within your home, causing health problems, odors, and mold growth from excess moisture. According to the EPA, because of this, the air in your home can be up to five times more polluted than the air outside, containing radon, airborne viruses, allergens, and more. Find out how fresh air ventilation systems can help you breathe Healthy Air.




Ventilation Systems Help Reduce:

  • Dust and Dust Mites
  • Carbon Monoxide
  • Tobacco Smoke
  • Ozone
  • Pollen
  • Pet Dander
  • Airborne Viruses
  • Mold Spores
  • Radon
  • Odors

According to the National Center for Biotechnology Information, U.S. National Library of Medicine, there are three types of ventilation systems: natural, mechanical, and mix-mode ventilation. Natural ventilation refers to windows or screen doors that allow fresh air to flow naturally into your home. Mechanical ventilation uses a mechanical fan to push fresh air into your home. Mixed-mode ventilation uses a combination of the two to supply Healthy Air.


Benefits of Mechanical Ventilation

Aprilaire’s ventilation systems use mechanical ventilation to push fresh air into your home. With proper maintenance, mechanical ventilation systems allow air flow to be controlled more easily, ensuring your family is breathing Healthy Air.

By regularly replacing your air filters, you’re ensuring the air you breathe is free from microorganisms, odors, and vapors regardless of weather, changes in humidity, or outdoor air pollution.


Reduce In-Home Moisture with a Mechanical Ventilation System

Mechanical ventilation also helps remove moisture from your home. Moisture is added to your home throughout the day through showering, laundering, and dish washing. In today's tightly-built homes, this added moisture cannot escape and creates an environment where viruses, bacteria, molds and dust mites thrive. Highly humid air can also damage your home, causing wood to swell, warp, or even rot. Mechanical ventilation fills your home with fresh air, pushing any excess moisture out.

Dos & 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.


forget to make sure your ventilation is up to code

Fresh air ventilation systems are recommended by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and required by California Energy Commission Title 24. Aprilaire ventilation equipment meets the requirements of the International Residential Code as well as the International Energy Conservation Code.


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.  

 ...the proper design, operation and maintenance of the ventilation system is essential in providing indoor air that is free of harmful concentrations of pollutants."

U.S. Environmental Protection Agency


Without ventilation, your tightly-sealed home is subject to stale, stagnant, polluted air. By properly ventilating your home, you’re filling it with fresh, breathable air while simultaneously maintaining airflow and removing harmful indoor air pollutants. Used in conjunction with the Aprilaire Healthy Air System™, you can even reduce the risk of airborne viruses such as the flu and common cold.
