2. How AC Filters Work

AC filters work by trapping particles as air passes through them. The filter media, whether it’s made of fiberglass, pleated material, or electrostatic material, acts as a barrier that captures particles and prevents them from circulating in the air.

For example, fiberglass filters use a dense mesh of tiny fibers to capture larger particles like dust and pollen. Pleated filters have a larger surface area, which allows them to capture smaller particles like pet dander and mold spores.

Electrostatic filters, nevertheless, use an electrostatic charge to attract and capture particles. The charged filter media acts like a magnet, pulling in airborne particles and trapping them.

HEPA filters are constructed with a fine mesh that can capture particles as small as 0.3 microns in size. This makes them highly effective at removing bacteria, viruses, and other microscopic pollutants from the air.

Regularly replacing or cleaning your AC filter is crucial to ensure optimal performance and air quality. A clogged or dirty filter can restrict airflow and reduce the efficiency of your AC system.
