Air Filter Efficiency Calculator
Compare air filter efficiency between different filter types and brands. Calculate filtration performance, cost-effectiveness, and find the best option for your needs.
Step 1: Filter Details
Understanding Filter Efficiency
Filter efficiency is measured by MERV rating (Minimum Efficiency Reporting Value). Higher MERV ratings indicate better filtration of smaller particles but may reduce airflow if not properly sized for your system.
Step 2: Environment Details
About MERV Ratings
MERV ratings range from 1 to 16, with higher numbers indicating better filtration. MERV 1-4 are basic filters, 5-8 are better for residential use, 9-12 are superior residential/commercial, and 13-16 are high-efficiency filters.

Filter Efficiency by Particle Size
Air Filter Efficiency Formula
Efficiency = (Particles Captured / Total Particles) × 100%
Filter efficiency is calculated by comparing the number of particles captured by the filter to the total number of particles in the air. Higher MERV ratings and proper filter sizing increase efficiency.
