What are tier 1 air filters?

Tier 1 air filters are high-efficiency filters designed to capture a significant amount of airborne particles, including dust, pollen, and other allergens. They typically have a Minimum Efficiency Reporting Value (MERV) rating of 11 or higher, indicating their ability to trap smaller particles effectively. These filters are commonly used in residential and commercial HVAC systems to improve indoor air quality and reduce the load on heating and cooling equipment. Regular replacement is essential to maintain their effectiveness.
