How Often Should You Change Your Home’s Air Conditioning Filter?, Monroeville, Alabama

Air conditioning filters are essential for maintaining the purity of the air in your home. Because of this important function, it’s crucial to clean and change them regularly. Clean filters remove allergens from the air and allow your HVAC system to heat and cool your home more efficiently. How often should you replace them, however? Here are several factors to consider.

Factors That Affect Your Air Conditioning Filters 

What Type of Filter Do You Have?

Not all air filters are created equal; high-quality ones have a longer life-span. Although they’re more expensive, you don’t have to replace them as frequently. Pleated filters, for instance, catch more dust, and only need to be replaced every three to six months, depending on the conditions in your home. Fiberglass filters are a lower quality option. They’ll do a fine job of catching the dust but will need to be changed as often as once a month. HEPA filters, considered the gold standard, may last from 12 to 18 months before they need to be replaced.

How Heavily Do You Use Your HVAC System?

air conditioningHVAC system usage also determines the frequency in which you need to replace your air conditioning filters. If you live in a house with young children who may track dust in from outside, or have dogs and cats that shed hair, you’ll likely need to replace the filter much more often than if your house is kept fairly clean all the time. Likewise, if the house is a primary residence, it’s more important to change the filter regularly than if it’s a vacation house where you only live for part of the year.

Does Anyone in Your Home Have Allergies?

If you or anyone in your home has respiratory issues like asthma or severe allergies, then maintaining the filter becomes even more important. Having air that’s free of allergens like dust and pollen can greatly improve the standard of living. Cleaning and replacing the filter more frequently will assist with this.
