Electrostatic air filters are a great way to improve the air quality in your home. With a MERV rating of between one and four, they capture up to 90% of dust, pollen, pet dander, bacteria, mold spores, and indoor air smoke. This is a much higher capture rate than standard pleated fiberglass or cotton filters. These filters use a combination of polyurethane and polypropylene layers and filter media to generate static electricity.
This static electricity attracts charged dust particles that float around the house, as well as bacteria and viruses with charged protein layers. It also captures pet dander, pollen, and other particles. The electrostatic air filter has a self-charging filter medium, so it can be washed and reused over and over again. This means you won't have to remove dust from your house as often because the filter will sequester it.
This keeps your home cleaner and nicer. Choosing an electrostatic air filter can also lower your utility bills because your heating and cooling system will be able to operate at its highest level of efficiency. The lack of mechanical filtering can also cause other problems, such as particles simply falling off the filter and returning to the air each time you remove it. If you suffer from a variety of airborne allergies, electrostatic air filters may be a reasonable way to reverse poor indoor air quality.
The Centers for Disease Control (CDC) recommends improved air filters and air purifiers to improve indoor air quality (IAQ) and combat Covid-19, especially for people with respiratory diseases.
