- AC filters and furnace filters with an efficiency rating of Merv 8 are able to remove pet dander, dust mites debris, lint, dust and pollen from the air. Electrostatic HVAC filters are different than regular home air filters. Negative and positive charges in the filter fibers attract dust and other airborne particles. This helps keep your home's air cleaner and safer for you and your family's long-term health. Indoor air quality can be even more polluted than outdoor air from mold, household cleaning products, pet dander and more. Given people spend almost 90% of the time indoors, make sure to change your home air filters regularly to avoid the long-term negative health effects of breathing in dirty air.

APR vs MERV
APR

This rating exists to demonstrate the different levels of efficiency throughout the Accumulair filter line. Generally speaking, the higher the APR, the better the filter performs in capturing small airborne particles. This rating system is an internal rating system and applies to Accumulair filters only.
MERV
MERV stands for Minimum Efficiency Reporting Value. It is a number from a test method designed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE). The number is intended to help people compare filters. Generally speaking, a higher MERV rating indicates better filter performance.
