This depends on what type of filter(s) you have, and the loading (loading refers to the amount of particles the filter has trapped). Essentially, you must replace the filter once it starts to reduce the air flow excessively. This can result in your furnace's heat exchanger over-heating, your safety limits getting damaged; it can even create a fire hazard1 It is also the leading cause of air conditioner services calls: a plugged filter can cause the evaporator coil to "freeze up".

This is dependent on the challenges imposed on the cushion. The average person passes gas 14 times a day. Not all outbursts however will be made on the specialty formulated membrane and we therefore based our design criteria on five outbursts per day. Based on this, our sample study shows a life span of six months for a women and half that for a man. The technically advanced filter in GasMedic will last two to four times longer.

A clogged air filter will reduce the airflow through your system, which could cause the blower motor to malfunction. It can cause your system not to work like it should, and could cause your indoor unit to ice up. If the air filter surface is extremely dusty, vacuum first, then spray with a household cleaner (409 or Fantastic). Let it sit for a couple of minutes to allow the chemicals to work, then back flush with water, rinsing the particulate back out the way it came in. Rinse thoroughly. See similar questions...

There's no one-size-fits-all answer. The frequency of filter changes is driven by how much your HVAC system operates, which is driven by the severity of the seasons. In some locations the cooling system might be in use more than four months of the year ? to keep heat and humidity under control. If your house is in such a hot and humid location, you should pay a lot more attention to your filter than in an area where the air conditioning is seldom used. The same logic applies to heating.
