What is the efficiency of a air filter?

Air filter efficiency is indicated by the filter’s MERV rating. MERV stands for Minimum Efficiency Reporting Value and is a measure of how effective a filter is a trapping and holding particulates. Standard MERV ratings span a range from 1 to 16, with higher MERV numbers meaning better filter efficiency.

Can a dirty air filter cause a high electric bill?

A dirty air filter affects indoor air quality and makes it difficult for your HVAC system to circulate conditioned air through your home. This drives up utility bills and makes your system work harder than it should.
