If you have a furnace filter, you may need to change it out. Changing your filter is a simple and easy process that can help improve the efficiency of your heating system. Changing your filter will reduce the amount of time you need to spend waiting for your heater to turn on or off, as well as keep debris and dust from building up in your furnace.

Here’s how to change your filter: first, turn off the power to your heating system. If you have a gas furnace, this means turning off the gas valve on the furnace. Next, open up any panels and remove screws from your air filter. Finally, replace it or install a new one before turning back on the power switch.

Changing your furnace filter can see an increase in the lifespan of your heating system by reducing the strain on your system as it works to heat your home. Let’s take a look at what we’ll be doing today and how it will make things easier for you going forward.

How to Find Your Furnace Filter

First, you’ll need to determine the part number of your filter. This is a 12-digit code that is printed on your filter or on the furnace itself. The code should be located somewhere near where the filter attaches to the furnace. Sometimes it can be found in another place. If so, check your owner’s manual for instructions.

Next, you’re going to want to look for your filter model number in our air conditioner filter comparison chart. If you don’t know what model number it is, we’ve got a handy guide with pictures of most filters and their model numbers that you can use as a reference.

Once you’ve found your filter model number, you can find the furnace’s model number online. If you’re unsure of what model number your furnace uses, you can use this handy guide to find your furnace’s model number.

Finally, we’ll look at where your filter is located on your furnace. This information should be included in the owner’s manual that came with the unit. If not, check with the manufacturer to see if they have a list of compatible filters.

How to Change a Filter

To change a filter, you will need to follow these steps:

  1. Turn off the power to your furnace.
  2. Have someone stand in front of the heater while you remove the old filter.
  3. Unscrew and remove the new filter from its packaging.
  4. Replace the old filter with the new one.
  5. Turn your power back on and enjoy!
  6. Why Should You Change Your Filter?

Changing your filters can also improve the efficiency of your heating system. Filters are devices that clean up air before it comes into contact with an appliance, such as a furnace or heater.

Filters are also known as air cleaners because they clean the incoming air by removing harmful or toxic particles. The efficiency of your heating system can be improved with a simple change in filter type and/or frequency, which may include monthly replacement filters for those who have central heat systems installed.

They’re not just there to make sure you have fresh breath in wintertime; they help maintain safe levels of carbon dioxide and pollen particles, so you don’t start coughing uncontrollably when no one’s around! As for changing out filters–if this process is done well, it will extend their lifespan too!

Some Things to Consider When Purchasing a New Filter

There are three things to consider when buying a new filter for your furnace: the size, material, and features. The size of the filter is important because it determines how much air you need to replace at a time.

The material dictates what type of airflow and water input your furnace will have, as well as if it’s reusable or disposable. A final feature would be something like an antimicrobial coating that prevents bacteria growth in the filter itself.

Buying a high-quality, durable filter can save you money in the long run as they will last longer than others. If you’re buying a replacement filter regularly, then you might want to buy one with extra features that could help save you time or money throughout its lifespan.


The right furnace filter can make all the difference in how effective your furnace is at heating your home. And the more effective your furnace is, the less expensive your heating bill will be. Changing a new furnace filter can be overwhelming. We’ve created this handy guide to help make it easier. Best of luck and happy cooking!
