Air filters are a key part of HVAC (heating, ventilation, and air conditioning) systems. Their main job is to clean the air that circulates throughout your home by trapping dust, pollen, mold spores, pet dander, and other small particles. By doing this, air filters not only help your HVAC system run smoothly but also improve the air quality you breathe by removing harmful substances. They also prevent dirt and debris from entering the system, which could otherwise reduce efficiency and affect your health.
The effectiveness of air filters depends on the materials they're made from. Many filters are made from fiberglass or pleated fabric, which can catch particles of different sizes. Some filters use special materials designed to trap even smaller particles. The filter's efficiency is often measured by its MERV (Minimum Efficiency Reporting Value) rating. By choosing the right air filter, you can protect your HVAC system, ensure cleaner air, and create a healthier living environment for your family.
