Central Filtration
HOW TO CHOOSE
Typical furnace filters are meant to protect the air handling system from large particles and do little to improve the air quality in your home. Only high efficiency filters can trap pollen, plant and mold spores, bacteria and other tiny particles that can bypass your respiratory defense system. High efficiency filters have a MERV (Minimum Efficiency Reporting Value) rating of 10 or higher. The higher the MERV, the more efficient the filter will be at trapping small particles.
MAINTENANCE
Replace your filter at the stated intervals instructed by the manufacturer, usually about every three months, to ensure proper air flow. Replace more often if you are introducing higher levels of particulates into the home, such as when renovations are being done.
