Change your filter when...

We frequently get asked "How often should I replace my air filter?", but unfortunately the answer is often 'it depends.' Many variables can determine how long your filter will last at optimum air flow. Some of these variables include, what type filter you ar using, what flooring is in the house, how many people are in the house, as well has the type and number of pets. Many manufacturers advertise that their filters last longer than their competitiors and catch more debris. Sounds contradictory to me. A filter that catches more debris should not last as long as a filter that catches less. I recommend that you use a standard pleated filter (white kind) as opposed to the fiberglass (blue kind). Merv 8 is probably the most common filter and anything above that may be overkill. A filter is not going to be able to keep your children from catching a cold or even prevent bacteria from entering the air conditioning system. I feel I am getting long winded and would be happy to respond to any other posts.
