Regular air filter replacement can reduce your energy bill by up to 15%. It will protect your HVAC system from unfiltered air and make it last longer. Knowing when to change your air conditioner filter is essential for keeping your home's air quality healthy and your energy bills low. When it comes to changing your household air filter, the general consensus is that you should check and replace it every month during peak season.
This is especially true if you have pets in the house, as they can contribute to a faster buildup of dust and other contaminants. If you have multiple pets or people with allergies or respiratory conditions, you should consider changing the filter every 20-45 days. Vacation homes or homes that don't get much use can expect to change filters every 9-12 months. It's helpful to know what size filter you need for your HVAC system.
Common sizes include 16 x 25, 20 x 25, and 20 x 20. You may also want to invest in HEPA filters with a MERV rating of 10 or higher if you want to improve the air quality in your space by eliminating pollen, mold, and other harmful contaminants. If you don't have a regular HVAC service technician to ask how to change an AC filter, you can do it yourself if you know where the filter is located, how to remove the old filter and insert the new one, and how to get the right filters for your system. An arrow on the filter frame indicates the direction in which air should flow through the filter, which is always away from the return air duct and into the air handling mechanism.
Discount Filters offers many different types of discounted air filters to help you better breathe the air inside your home based on your specific needs. MERV 17 to MERV 20 filters are commonly used in operating rooms, cleanrooms, and other settings that require absolute cleanliness. You can also set up a calendar reminder so that you don't forget when it's time to replace your filter.
