What is an Electrostatic Air Filter and How Does it Work?

Electrostatic air filters, also known as washable filters or reusable filters, are found in an oven and usually replace a pleated filter. The main purpose of any filter is to clean dirty outdoor air that is forced into your home. Like any filter, the electrostatic filter removes fine particles and dirt from the air, preventing heating or air conditioning from recirculating dust, pollen, pet hair, pet dander, microorganisms, and other tiny debris around the house. The filter also stops dust and dirt before they reach the HVAC unit, reducing the risk of wear-related damage and increasing efficiency. An electrostatic air filter works inside the ducts of an HVAC system and efficiently removes more than 95 percent of particles floating in the air.

These filters use a safe electrostatic charge that traps some of the smallest particles and contaminants in the air. In effect, the principle works the same way as a magnet: charges trap dust in filters, making the air cleaner for everyone to breathe. Most common household contaminants, such as mold, pollen and pet dander, are all larger and are easily picked up and removed with a standard air conditioning filter. Cleaning the filter every three to four weeks should keep the system clean, but consider replacing it with an electrostatic filter if the system doesn't produce clean air. The 94% retention filter provides greater filtering capacity by trapping up to 94% of airborne particles. Thanks to their construction material, they continue to have a natural charge and, in fact, their charge increases over time as the air passing through the filter helps to accumulate a little charge.

As mentioned earlier, pleated filters fall into two categories when talking about electrostatic air filters. An HVAC contractor can evaluate your heater and air conditioner and recommend the best option for you. In conclusion, electrostatic air filters are an effective way to improve indoor air quality by trapping more particles than traditional filters. They are also more efficient at trapping smaller particles than traditional filters. However, it is important to remember that they require regular maintenance in order to keep them working properly.
