We are coming across many homes using the $30-$40.00 1″ Merv 11-13 furnace filters. The higher the Merv rating the finer the particles that are caught in the filter, which seems to be common knowledge at this point. However, that also means more restriction to your airflow. Straight out of the packaging it will restrict your airflow more than a basic Merv 8 pleated filter ($10), so it doesn’t take much dust to start effecting the efficiency and life span on your forced air system.
If you have allergies, asthma or just simply hate the thought of airborne particles in your home we would recommend you stay away from the 1″ Merv11+ filters, and upgrade to a 5″ filter to allow for better airflow. We can install this simple 5″ media filter rack in most homes for as little as $250.00. Which will prolong the life of your equipment and allow higher efficiency. We offer a full line of clean air products that are high in filtration and easy on your HVAC system.
