A Guide to Changing your Indoor Air Filter

Why Change the Filter?

Over time your indoor air filter becomes filled with dust particles that travel through your home’s air ducts. The filter’s purpose is to pick up dust and prevent it from entering the heating and cooling unit, and from cycling through your home. Filters are made to catch dirt and debris, so over time they should and will become dirty and full.

When the filter has caught all the dirt and dust it can handle it will stop being effective. When this happens it becomes harder for the air to pass through the filter and the air that does pass through isn’t cleaned as well as it should be. Changing the filter is an important part of maintaining your air duct system and maintaining clean breathing air in your home.

How to Determine if the Filter Needs to Be Replaced

To determine if your filter is in need of a replacement you can simply pull it out and examine it. A filter that needs to be changed will appear dusty and dirty. If you are unsure whether the filter needs to be replaced, consider replacing it on a regular schedule, such as every three months.

There are some other considerations to take into account when deciding how often to change your filter. The amount of pets you have in the home will greatly impact the amount of time you can get out of a filter. On average a filter can last approximately three months, but if you have several pets you will want to change it every 30-60 days instead.

Steps to Replacing the Filter

To replace the filter you’ll first want to figure out what type of filter to use, this information should be available with your HVAC units information.

Once you’ve determined the type of filter to use, turn off the unit and remove the existing filter from its place in the unit, the air filter slot. If you have trouble locating this consult the units guide, or contact the company that installed the unit for you.

Once you’ve removed the existing filter you can insert the new one, close the slot, and turn the unit back on. Before turning the unit back on quickly check the new filter to ensure it fits in the slot properly.

After you are finished you can throw away the old filter as you won’t need it anymore. If you were unsure of which kind of filter to purchase, it may be a good idea to write that information down for the next time the filter needs to be changed.
