How Often Should You Change Your Furnace Filter?

It's important to keep your furnace filter clean and replace it regularly to ensure your home's air quality is healthy and your HVAC system is running efficiently. But how often should you change your furnace filter?Most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. This may vary depending on the location of your home, if you have pets, and the age of your system and equipment. If you have pets in the household, you should consider changing the filter every 60 days or 2 months, and for households with multiple pets or people with allergies or respiratory conditions, we recommend changing the filter every 20-45 days.

Vacation homes or empty homes that don't see much use can wait to change filters every 9 to 12 months. The general consensus is that the more you use your home, the more you need to change the air filter. It's also important to note that filters with higher MERV ratings should be changed more often than those with lower ratings. Filters with a MERV rating of 6 to 9 should be changed every 90 days, while those with a MERV rating of 10 through 12 should be changed every 60 days. Be sure to check your oven's owner's manual for the best MERV rating for your oven. It's also important to note that Honeywell oven filters have the same filter replacement recommendations as standard filters.
