Not sure what MERV means? Learn how to choose the right filter for your commercial or industrial HVAC system with this quick guide.
When it comes to choosing HVAC filters, one of the most important (and misunderstood) metrics is the MERV rating. Standing for Minimum Efficiency Reporting Value, MERV ratings range from 1 to 16, and they measure how effectively a filter traps airborne particles.
MERV 1–4: Basic dust and pollen protection
MERV 5–8: Common in residential and light commercial buildings
MERV 9–12: Ideal for hospitals and high-traffic buildings
MERV 13–16: High-performance filtration for surgical centers or cleanrooms
At CAP Filtration, we help you find the perfect balance between airflow and filtration efficiency to meet your space’s unique needs. Remember: higher isn't always better—it's about the right fit for your system.
