How Do Electrostatic Air Filters Work?

Posted on: October 13, 2016

Electrostatic air filters are made of multiple layers of vented metal. As the air passes through the layers, the molecules become positively charged by the friction between the air and the filter. This positive charge causes dirt particles in the air to cling to the metal surfaces of the filter, preventing most dirt from passing through to the furnace and air ducts.

Advantages of Electrostatic Air Filters

The main advantage of electrostatic air filters is that they are reusable, and therefore can save money over time. When the filter becomes dirty, you simply vacuum or hose it off. While the up-front cost is more than most disposable media filters, they should last a long time.

Disadvantages of Electrostatic Air Filters

There are several important disadvantages to electrostatic air filters. First, high quality disposable media filters are usually more effective at removing fine dirt particles. Second, because they charge the air, any dirt that makes it through the filter will cling to air conditioner coils and air ducts, causing dirt to accumulate, and potentially causing air quality issues. Finally, a standard media filter is simple to dispose of and replace, while electrostatic air filters require time to clean off.
