Understanding HVAC Air Filtration Basics
The air filtration system in your HVAC unit is key to a comfy and healthy indoor space. HVAC air filters catch dust and other particles as air flows into the system. They’re placed between the return duct and air handler.
How Air Filters Work in HVAC Systems
As air moves through your HVAC, it goes through the air filter. This filter stops contaminants. The filter’s MERV rating shows how well it works. Higher MERV ratings catch smaller particles, improving air quality.
The MERV Rating System Explained
The MERV rating system rates air filters by how well they catch different-sized particles. Basic filters (MERV 1-4) catch big particles like dust and pollen. Higher-rated filters (MERV 9-12) catch up to 95% of smaller particles, like bacteria and smoke.
Different Types of Air Filters Available
There are many HVAC air filters to choose from, each with its own benefits:
- Fiberglass Filters: These are cheap but catch only big particles.
- Pleated Filters: Better at catching small particles, they still let air flow well.
- Washable/Reusable Filters: Clean and reuse them to save money over time.
- HEPA (High-Efficiency Particulate Air) Filters: They catch almost all particles but might slow air flow.
- Electrostatic Filters: Use static to catch small particles, but need cleaning often.
Knowing about HVAC air filtration, MERV ratings, and filter types helps you pick the best one for your space.
