Important Facts To Know About Your Home Furnace Air Filter

Posted On: November 07, 2012

Air filtration is an important for a number of reasons. We usually only think about our furnace filter when we’re dusting around the house or sneezing from the airborne particles that appear when the furnace turns on in the winter.

How Often Should I Replace My Air Filter?
Filter replacement frequency varies by filter type, by the size of your home and the overall air quality. A furnace in a larger home will move more air and clog the filter faster. If you have pets you’ll probably need to change your filter twice as often. Not only are pet dander and hair a leading cause of allergens, they also clog air filters quickly!

Start with every two months for a pleated 1” filter and double the frequency if you have a large home or if you have pets. Costlier filters may claim to last 90 days, but, in our experience, these filters are so restrictive that they should be changed monthly. Your furnace and air conditioner will breathe easier and so will you!

Choosing a Furnace Air Filter
If you’re really interested in cleaning the air in your home, we can install a whole-house air cleaner in place of your furnace filter. These filters clean the air better that any of the standard filters and they often only need changed annually.

Buy your air filters by the case (usually 6 to 12) and keep them near your furnace. This will lessen the tendency to procrastinate about your air filter change. Buying by the case can also reduce the cost of each filter change.

Never run your system with an incorrectly sized filter. An poor-fitting furnace filter will allow dust and other contaminants to sneak around the filter and into your home. This is also the primary cause of clogged air conditioner coils. Clogged AC coils reduce efficiency and compressor life, and can cause expensive problems down the road.

Always turn off your furnace at the breaker panel or disconnect (not just the thermostat) before replacing your filter. Some furnaces have electrical wiring close to the filter location which could shock you if the power is not disconnected first. furnace air filters
