Electrostatic Furnace Filters: What They Are & Why They Matter

Not many people realize the fact that the air filter is a critical component of the furnace that must be kept clean at all times. The filters prevent the dust, dirt, and debris away from entering the system. These air borne pollutants can cause serious damage if they get inside the system.

Spending a little extra on high quality filter can pay you in the long run. In this article, we will talk about electrostatic furnace filters in detail so that you can be able to make an informed decision about whether they are worth the extra money.

What are Electrostatic Furnace Filters?

The electrostatic filters are different from standard filters in that they create their own electrostatic charge. Dust and other pathogens are removed by static electricity. When the static charge is created, the dust and other particles are attracted to the filter that becomes trapped.

Electrostatic filterThe filters are generally made of a heavy duty aluminum frame with 2 layers of special polypropylene weave on the back and the front. The unique poly internal lining ensures long lifespan of the filter thereby saving you costs overtime.

Pros of electrostatic filters

The main benefit of electrostatic filters is that they are reusable. You can wash the filters and then place them back inside the system. Also, the filters do an adequate job of filtering the air keeping dirt, dust, and other debris outside the system. The filters are as efficient as a pleated filter having a MERV rating of 5 or 6.

In addition, the typical electrostatic filters are normally 80 to 85 percent more efficient as compared to standard filters. Thus, you can save hundreds of dollars by installing electrostatic air filter.

Cons of electrostatic filters

Most electrostatic furnace filters don’t have many drawbacks. However, some cheaper brand filters do not adequately remove dust and other allergens from entering the system. As a result, the cheaper filters are not ideal for persons that suffer from dust allergies. Also, the filters need to be cleaned more frequently as compared to standard heaters.


Remember that the best filter is the one that ensures optimum air flow while still keeping dust and other allergens out of the system. The filters should be able to remove a high percentage of air pollutants thereby protecting the system from developing major defect.
