Electrostatic Air Filters: How Do They Work?
Electrostatic Air Filtration in Greater Los Angeles
Charge Up Your Air. Clean, Reusable Filters.
Standard air filters rely on mesh or pleats to catch dust and debris. Electrostatic air filters add static electricity to the mix. They attract fine particles like pollen, smoke, and bacteria that plain filters miss. You rinse and reuse them, cutting filter costs and waste without sacrificing air quality.
At Air‑Tro, we install and maintain electrostatic filters for residential furnaces and HVAC systems. Our team shows you how to clean filters and keep your system running smoothly.
Do electrostatic air filters really work?
Yes. Electrostatic filters use charged fibers to grab particles as small as 0.3 microns. Independent tests show they can trap up to 94% of airborne pollutants, including dust, mold spores, and pet dander. (arpis.com) Paired with quality filtration, electrostatic air cleaners boost your system’s ability to clear invisible hazards.
These filters run at standard airflow. You won’t lose power. And you can wash them every month to restore performance. That means cleaner air for your home and fewer filter replacements.
How Electrostatic Filters Work
Electrostatic filters contain multiple media layers treated with an electric charge. As air flows through, particles pick up opposite charges and stick to the fibers. Over time, the filter holds more particles. When it looks dirty, you remove it, rinse with water, and let it dry. The charge returns, and it’s ready to work again.
This process gives two major benefits. It traps small particles that pass through standard filters. And it reduces the need for disposable filters, saving money and cutting plastic waste.
