An electrostatic air filter works by using air filter material (aka media) that produces static electricity that is created when air and particles flow to and rub the media. This static electricity “charges” the particles and makes them stick to the air filter media. In this way, an electrostatic air filter works like a magnet.
We all know what static electricity is when we hear or see it. Sometimes clothes come out of a clothes dryer with static cling. The clothes cling together. This is caused by the clothes rubbing against each other in the dryer.
Scientifically, when two solid materials are rubbed together, a static charge buildup is formed. This occurs because electrons start moving around and affect the “charge” of the materials.
We use multiple layers of an electrostatic media called polypropylene. We arrange the layers in a unique way to capture the most particles. We do not use inferior materials like foam or polyester. This is why our filters are washable and can last a lifetime.
Our filter media also contains antimicrobial protection that will not allow bacteria and mold to grow. This protection is permanent and will not wash off.
Our filter frame is made from heavy-duty aluminum, not flimsy cardboard. The filter media is held in the frame with heavy gauge wire on each side.
MERV stands for Minimum Efficiency Reporting Value. Ratings range from 1 to 16 and then there is HEPA (High-Efficiency Particulate Air filters). Choosing the air filter MERV rating is really a balance between capturing particles in the air while allowing air to continue to flow through the HVAC system.
Most home HVAC systems are designed to use air filters with MERV ratings from 1 to 8. MERV 1 air filters allow lots of airflows but do not capture many particles. MERV 7 air filters still allow good airflow but also capture more particles like dust and mold.
We make HEPA filters too, but these simply don’t allow enough airflow for most HVAC systems. HEPA filters are generally used in hospitals and other settings where extremely clean air is required.
