Types of Air Filters
Air filters come in various types, each with its own efficiency rating. The most common types include:
- Fiberglass filters: Inexpensive and disposable, these filters capture large particles like dust and hair.
- Pleated filters: Made from pleated fabric, they offer higher efficiency than fiberglass filters and trap smaller particles.
- HEPA filters: High-efficiency particulate air filters are the most effective, capturing 99.97% of particles as small as 0.3 microns.
How to Determine the Correct Filter Size
The size of the air filter you need depends on the specific air handler in your home. To determine the size, measure the width, height, and depth of the existing filter. Alternatively, refer to the manufacturer’s recommendations for your air handler model.
