Replacing & Cleaning Your Furnace Filter

When used, a furnace’s filter should be cleaned or replaced about once a month. This allows the furnace to operate at maximum efficiency. When a filter is clogged, it takes more energy to heat your home, which costs more money. There are various filters, and those can be easily purchased at a hardware store if you use a replaceable one. More advanced filters are not replaced each month but are cleaned.

Whether you are cleaning or replacing, here are some instructions:

  • Turn off the furnace either at the main circuit breaker or the service panel on the furnace.
  • Look for the filter, a square or rectangular mesh device, usually found near the blower.
  • Remove the filter and wash it if necessary.  Before putting it back in the furnace, make sure that it is dry!
  • If you bought a new one, check to be sure it is the right size and then replace the old one.

This might seem like a hassle, but it is well worth it for your furnace and wallet.
