Replace or clean furnace filter

Depending on your heating system, you should replace or clean filters as necessary. Most systems require a replacement filter, but some advanced systems require just cleaning out an existing electrostatic filter. Filters typically catch dirt, dust, pollen and other airborne contaminants that keep the re-circulated air in your home healthier for you and your family.

How to replace a furnace filter

The first thing to do is to locate your furnace which is often times in the garage or even in a small closet in the home.  Locate an access panel where the return air is and you should see a filter.  Remove the current filter and determine the exact size.  They usually vary in rectangular shapes.

Buy replacement filters that are the exact same size.  You don’t want a filter that is too small as unfiltered air will blow around it thus making it unusable.  Higher priced filters will block out more allergens and other micro particles.

Here is a great video from Howcast on how to change the furnace filter.
