How to Clean or Replace a Furnace Filter

The obvious reason to change your furnace filter is because that filter is what is removing all the dust, dander and debris from your air in your home. Remember, there are two filters in your house – your furnace filter and your lungs! Let’s make sure the furnace filter is taking the brunt of the dust and allergens, not your body.

Why is it so Important to Clean My Air Filter on Furnace?

A clean furnace filter can cut your heating bill by 5 to 15 percent. If you live in a cold area of the world, it is likely that the majority of your home-energy expenditure will go towards your furnace. Cleaning your furnace filter is an easy and cheap way of reducing your energy costs and improving your indoor air quality.

How to Clean or Replace a Furnace Filter?

Step 1
Locate the service panel, usually on the furnace’s lower front or side.

Step 2
Turn off the furnace, then gently pop open or pull down the panel door with your hands; tools usually aren’t needed.

Step 3
Locate the filter-a framed-mesh rectangular screen inserted either horizontally or vertically near the intake-outtake blower.

Step 4
Check for brown, dusty buildup on the mesh screen (or a screen you’re unable to see through).

Step 5
If you have a reusable plastic-frame or metal-frame filter, use a hose to rinse away the dust particles on the screen in the backyard or driveway. Let it dry, then return it to the furnace. If you have a disposable cardboard-frame filter, write down the size, then throw it away. Buy a new furnace filter of the same size (available at hardware and home supply stores).

How Often Should You Replace Air Filters?

The short answer is, you should at least change your filters once a year, preferably every three to six months. But it also depends on how many people are in your home, the appliance in question, if you have pets, and if you or others living with you are sensitive to allergies. Families with more than one pet should consider changing HVAC (Heating, Ventilation and Air Conditioning) air filters every two months. For other appliances it’s important to set up a routine so you don’t forget to change the filters. Frequency is specific to the individual, but once you’ve done it a few times, you’ll begin to see a pattern of when they should be changed. Over time, you’ll develop a routine that you can put on the calendar so you don’t fall behind.

In the end, the state of air filter will determine the quality of air as well as energy efficiency of the system. Regular cleaning of the system will ensure that the system works efficiently in heating the room.
