How Ventilation Affects Your Indoor Air Quality

Chris Helms - Thursday, May 14, 2015

What do you need to know about how ventilation impacts your indoor air quality?

Indoor Air Quality and Ventilation

Indoor air quality is a concern to most of us, especially in the spring and summer when allergens are plentiful. Which factors in your home affect your indoor air quality the most? You may be surprised to learn ventilation is one of the key factors. Here’s how it works:

From the Outside In

All of those pollutants and allergens in the air outside in the spring and summer don’t like to stay outside. They come inside on your shoes and your clothes, through open windows and doors. What’s ventilation got to do with this?

As the pollutants come into your home, your cooling system pulls in interior air and recirculates it through your home. Anything in the air travels through your ventilation system. Some of it gets filtered out by the air filter, but some of it gets stuck in the vents where it can get picked up and pushed back out into the rooms in your home.

Prevention Is the Key

How do you prevent all of those pollutants from recirculating through your house? There are a few ways.

The first method is simple, inexpensive, and something you should be doing anyway: checking and changing the air filter. A clean air filter is more effective at filtering out more of those pollutants.

The second method is with an effective air purification system. A good system can make a huge improvement in your air quality filtering out more than 90% of pollutants.

Don’t let dirty vents make your indoor air quality plummet. A few simple measures can have you breathing easier.
