Here is a chart of MERV rating for air filters. Understanding MERV ratings is key to selecting the right furnace filter for your home or business. This chart simplifies the comparison, showing how each MERV level impacts air quality by capturing different sizes and types of airborne particles. Whether you're looking to reduce dust and pollen or tackle microscopic allergens and bacteria, this guide helps you choose the filter that best meets your indoor air quality needs. Use it to find the perfect balance between filtration performance and HVAC system efficiency.

MERV stands for Minimum Efficiency Reporting Value, a standardized rating system developed by ASHRAE (the American Society of Heating, Refrigerating, and Air-Conditioning Engineers). It measures how effectively an air filter captures airborne particles of varying sizes. The higher the MERV rating, the more efficient the air conditioner filter is at trapping smaller and more harmful contaminants.
