How to Choose the Right HVAC Filters for Better Air Quality
Choosing the right HVAC filters is crucial for maintaining indoor air quality and system efficiency. Filters are rated by their Minimum Efficiency Reporting Value (MERV), which indicates their ability to capture airborne particles. For residential use, MERV ratings between 8 and 12 are ideal, as they trap dust, pollen, and pet dander without restricting airflow. HEPA filters, with higher MERV ratings, are recommended for those with allergies or respiratory conditions as they capture microscopic particles. However, not all HVAC systems can handle high-MERV filters, so check compatibility first. Pleated filters offer a larger surface area for capturing contaminants, while electrostatic filters attract particles using static electricity. It’s also essential to replace filters regularly, typically every 1 to 3 months, to maintain efficiency. By selecting the right HVAC filters, homeowners can improve air quality, enhance system performance, and extend the lifespan of their HVAC units.
