How Often Should AC Filters Be Changed?

Home ownership involves a wide variety of time-consuming activities that must be completed in order to keep the property in good repair.

Any of them, such as getting the heating and cooling system serviced, are likely to be done on an annual basis. Others are less time sensitive.

How often, for example, do you change your home air filter?


Air Filter for the Home


Most experts suggest changing your home air filter every 60-90 days in a home that is occupied nearly all year, depending on a variety of factors listed in detail below, such as pets, allergies, and so on.

Deciding when to replace your home air filter can be difficult for a variety of reasons. Every house is a little different, which can change the response to this frequently asked question. The type of air filter you buy will affect how frequently you need to replace this important piece of equipment. Although the response can differ from home to home, it’s critical that you figure out exactly what your home requires to run smoothly.

Changing your air filter every ninety days is a reasonable benchmark. That means you can replace your air filter at least once a quarter with a fresh, clean one. However, if you have pets, allergies, or even a holiday home, this will vary.

What Effects Do Pets Have on Your Air Filter?


Pets will make determining how often you can adjust your home air filter more difficult. Adding a cat or dog to the mix increases the amount of pet dander, dust, and hair in your home’s air. Both of these things work together to clog your filter’s air flow. This is why, if you have a pet in the building, experts suggest changing your filter much earlier or every 60 days.

What about animal lovers who have more than one pet? Dander, dust, and fur can all clog up your HVAC machine and cause it to malfunction. Homeowners who have more than one cat or dog can replace their air filter every 30 days.

Allergies Have an Effect

If you suffer from allergies, changing your home air filter on a more frequent basis is just as necessary. Excess dust, dander, and other air pollutants get caught in your air filter and end up in your house. This can result in runny noses, horrible coughs, and other allergy symptoms that you’d rather avoid. Some allergy sufferers tend to change their air filter every two weeks just to get some relief from their symptoms. Others with milder allergies can be able to get away with changing their air filter every thirty days.

Low Occupancy Lengthens Life Expectancy

What happens if you don’t live at home full-time or you travel extensively? A separate consideration should be made for vacation homes that are only used for a limited portion of the year. There are less air pollutants stuck in your air filter and no one is living in the building. You can greatly extend the time between air filter adjustments. Many of these homeowners just change their filters once a year or every six months.

And single people who live alone can be able to make their air filter last longer. If you live alone and don’t have any pets, changing your air filter every four to six months should suffice.

Why Is It Important to Replace Your Air Filter?

Sure, you’re aware that your heating and cooling system has a significant impact on your home’s overall comfort. Nobody wants to go through the scorching summer heat without the comfort of air conditioning. Is it really that important to replace your air filter on a regular basis?

If you’re still not sure that replacing your air filter on a regular basis is the right decision for your home, consider a few of these compelling factors.

Save Money On Repairs

The reality is that adjusting your air filter is critical to maintaining the efficiency of your HVAC system. Dust, dirt, pet dander, and other air pollutants float around your house, and your air filter absorbs them over time. While the air filter can be clean and white when you first put it in the return, it quickly becomes gray and dusty as time passes. Your HVAC system is placed under a lot of stress as a result of this deterioration.

A clogged air conditioner will put a lot of pressure on your system. The extra work eventually leads to much-needed upgrades, or the unit’s lifetime can be shortened. You can help keep the sections of your air conditioner cleaner and reduce wear and tear by removing the air filter. By completing this one basic mission, you might theoretically save thousands of dollars.

Reduce the Amount of Money You Spend on Cooling

Have you ever wondered what you should do to save money on your monthly energy bill? Those bills can quickly balloon to astronomical proportions, particularly during the summer. By investing in a new air filter for your HVAC system, you can do yourself a favor and cut some of those costs.

Your HVAC machine needs to work even harder to drive fresh air through and into your home when the air filter is dirty and clogged. This additional work consumes more electricity and can quickly drain your bank account. Consider how much money you will save by purchasing a low-cost air filter every few months!

Improve the quality of your indoor air

If you spend too much time indoors, you can experience regular headaches. Maybe you’re one of the unlucky people who gets severe allergies when they’re exposed to bad indoor air quality. The air inside our homes is two to five times more polluted than the air outside, according to the Environmental Protection Agency (EPA). This can trigger a variety of symptoms that you were previously unaware were linked to the overall operation of your HVAC system.

You can avoid breathing in dust mites, pet dander, and other tiny particles by using a filtered air filter in your home. Instead, you should take a deep breath of fresh air and feel good about yourself because you’re doing something good for your health.
