How Often to Change the Air Filter

how often to change the air filter

The answer to the question of how often to change the air filter depends on a few factors. Depending on the type of filter, it may vary from manufacturer to manufacturer. Some recommend changing the filter every 45,000 miles, while others say to change it every 15,000 miles or when there is excessive heat in the cabin. According to Gregory Prokopenko, chief mechanic at Momentum MotorSports in Quebec, changing the air filter at least once a year is the best policy.

If you have allergies

If you suffer from allergies, you should change your air filter more often than normal. Basic filters should be changed every thirty to sixty days, and people with asthma should change them at least twice a year. If you are a heavy HVAC user, you should change the filter every month. The best time to replace your filter is when you have a sudden spike in allergies, like spring or fall. But this can vary.

If you live in a single-occupancy home

The answer to the question “how often to change the air filter in a single-occupancy home” depends on several factors, including how many people live in the home, whether the home is pet-free, and the type of air pollution in the area. However, whatever the answer is, timely replacement is important to maintain the quality of air inside the home.

If you have a car

The frequency at which you should change your air filter varies from one manufacturer to the next and even from driving conditions. Some recommend a yearly replacement, while others say it’s important to change it every 15,000 miles or two years. To make sure you’re getting the most out of your filter, you can consult the owner’s manual of your vehicle to find out the recommended interval. You may need to change the air filter more often if you drive in dusty environments or on unpaved roads.

If you have a furnace

If you have a furnace, how often should you change the air filter? The answer depends on the type of filter you have. Thin filters collect less debris than thick filters do, so they don’t need to be changed as often. Thick filters also tend to last longer. The rule of thumb is to change the air filter every three to six months. If you live in a city, your filter will get clogged more frequently than a rural area.

If you have a Pleated air filter

You might wonder how often to change a Pleated air filter. It is a good idea to follow the manufacturer’s recommendations, which range from 60 to 90 days, although more advanced models can last up to six months. The filter’s efficiency degrades as dirt and other particles accumulate on its surface. The thickness alone isn’t enough to determine how often to change it. You also need to consider the number of people in your home, as more people and pets mean more dust and dirt will build up on the filter.

If you have a Fiberglass filter

The answer depends on your needs and climate. For example, if you live in a desert, you might want to change your filter once every six months, while a high-efficiency fiberglass filter requires changing it every 30 days. However, if you live in a city with higher pollution levels, you might want to change your filter even more often. Fortunately, many retailers offer recurring shipments, making it easy to stay on top of the air filter replacement schedule.

If you have a Pleated filter

The most common pleated air filters need to be changed every 90 days, although they may last as long as 120 days, depending on usage. The longer the air filter stays in place, the less efficient it becomes. The longer the filter lasts, the higher the price tag. If you have a pet, you should replace it more often, and if you are allergic to dust, you should consider purchasing a monthly filter.
