Change Filters RegularlyWe get calls from curious Minneapolis residents who want to know how exactly electrostatic filter impact indoor air quality. We know that indoor air quality is important to our clients, so we thought we would take some time to look into this issue.

In this article, Northern’s One Hour Heating & Air Conditioning looks at electrostatic filters and the link to improving indoor air quality in homes.

What is an Electrostatic Filter?

Electrostatic Air Filters clean the air by using static electricity. This is a safe, naturally occurring phenomenon that’s been harnessed in order to improve indoor air quality. An electrostatic charge is created by air flowing through a pathway of static prone fibers. During this process airborne particles are drawn to and held by the static charge until the filter is later washed.

How This Filter Improves Air Quality

All of us enjoy breathing clean, fresh air. For those family members who suffer from allergies and other respiratory issues , clean indoor air is more than a luxury—it’s a necessity. Electrostatic filters have plastic or metal strips that generate static electricity when air is pulled through them. These filters can do a much better job improving air quality than some products when maintained properly.

Upside and Downside


  • Better for homeowners because they can be washed and reused
  • Clean filters don’t impact the air flow of your home
  • Less expensive in the long run


  • Filters must be cleaned monthly
  • Highly investment up front

Even standard air filters should be changed every month or so, so this isn’t a huge departure from a regular maintenance schedule. And you’re upfront cost will be returned to you through improves indoor air quality.
