- Pleated furnace filters and pleated AC filters will clean your home's air more effectively than low cost fiberglass air filters. Pleated home air filters are made from a synthetic media which can filter out much smaller particles from the air such as dust mites, mold, pet dander and even viruses in the case of high Merv rated filters. Today, people spend up to 90% of their time indoors. This makes the air we breathe inside important to our short and long-term health. Indoor air pollutants such as household cleaning products, mold and pet dander can be effectively cleaned from the air when a home's air filter is changed every 90 days or sooner. Don't risk you or your families health. Be sure to follow the manufacturer recommendations and even change your HVAC filter sooner if it is dirty when checked.

APR vs MERV
APR
APR stands for Accumulair Performance Rating. This rating has been established by the manufacturer of the Accumulair Filters. 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.
