What Type of Furnace Filter is Right for Your Home?
Regularly Change Your Furnace Filters to maintain both your furnace and indoor air quality. Most furnace filters last about 3 months, but it’s recommended that you inspect your furnace filter monthly and replace it when required.
Furnace Filters Remove Various Particles From The Air before they enter your heating system through the return ducts. Removing these particles helps protect sensitive components in your furnace (such as the blower fan) and improves your indoor air quality.

Common Questions About Furnace Filters
What does the MERV rating mean on my furnace filter?
MERV 1-4 | Least Efficient These filters are the most basic. While they can remove lint and debris from the air, they are not fine enough to catch small particles.
MERV 5-8 | Moderately Efficient Pleated filters are made from folded cotton and paper materials. These filters can remove finer particles from the air as well as household lint and dust.
MERV 9-16| Most Efficient These highly effective filters can remove microscopic particles from the air, including smog, pollen, smoke, mold, spores, and dust.
A MERV (minimum efficiency reporting value) rating is a valuable piece of information when purchasing furnace filters, as it defines what kind of air particles a filter will pick up. For example, hospitals will use filters with higher MERV ratings for better air purity.
How do I know what type and size of filter to use for my furnace?
The type and size of filter you should use for your furnace will depend on its make and model. Consult the manufacturer’s instructions to find out what kind of filter your specific furnace needs.
How does a furnace filter work?
A furnace filter works by trapping pollutants and particles as they pass through the filter, preventing them from circulating through the air in your home.
How often should I change my furnace filter?
We recommend changing or cleaning your furnace filter once at the start of each heating season, and every 3 months for as long as you are regularly using the furnace.
What is a furnace filter?
Furnace filters are installed in your home’s heating system and filter the air that it draws in through your return and back into your home.
Can I wash and reuse my furnace filter?
Reusable filters can be washed, while disposable filters must be replaced regularly to prevent air quality and efficiency issues. Consult the manufacturer’s instructions for your unit or contact Action Furnace to determine whether your filter can be washed and reused.
Why is it important to clean or change my furnace filter?
As your furnace filter traps pollutants, it becomes clogged and less effective. If a filter is not changed regularly (or cleaned, for reusable filters), it can lead to poor indoor air quality and reduce the efficiency of your heating system.
What happens if I use the wrong size or type of filter for my furnace?
Using the wrong size or type of filter for your furnace can lead to poor indoor air quality and reduced efficiency of the heating system. It can also cause damage to the furnace itself.
Can a dirty furnace filter cause my furnace to malfunction?
Yes, a dirty furnace filter can cause your furnace to malfunction. A clogged filter can restrict airflow, causing the furnace to overheat and potentially leading to shutdowns and component failure.
Can I install a furnace filter myself?
Yes, installing a furnace filter is a relatively simple task that can be done by a homeowner. However, if you are unsure of the correct type and size of filter to use, or if you encounter any problems during the installation process, contact Action Furnace for assistance.
