How Long Can Air Purifier Filters Last?

If you are looking for air purifiers or just want to know more about them, you may want to know: "how long can air purifier filters last?" Since almost all air purifiers require air filters to remove pollutants from the air, so the service life of air filters is crucial.

Here are the basics of what you need to know about air purifier filter life.

How Do Different Filters Work and Wear Out?

There are various types of air purifier filters, each of which lasts for a different time depending on how they remove impurities from the surrounding air. For example, the HEPA filter uses a thin layer of porous material to capture small particles in the air. Filters wear out when the material becomes too full to trap more airborne particles.

On the other hand , the operating principle of the carbon filter is similar but slightly different. These filters use chemically activated carbon to capture gaseous impurities, such as odor and volatile organic compounds, from the air. However, like the HEPA filters, these filters will eventually reach their maximum capacity and no longer be able to remove more gases from the home air .

So, How Long Can Air Purifier Filters Last?

The service life of the air purifier filter depends on a variety of factors, including the type, size and use of the filter. Many larger HEPA filters, like those in the Amaircare 3000, can last up to 5 years under the right conditions, though 2-3 is more realistic in spaces with larger amounts of particulate matter in the air. For carbon filters, the average lifespan is generally 3-5 years.

Be aware, however, that not all units have the same specifications. Some air purifiers need to change air filters more frequently, so be sure to read carefully the air purifier's manual to determine the life of its filters.

When to Replace Filters

There are several different ways to know when to replace the air purifier filter. Some units equipped with an indicator light that will let you know when it’s time for your filter to be changed. If your unit doesn’t have this feature, you can simply keep track of the time since your last change and replace the air filter after the recommended interval.

Another option, if you don’t want to keep track of multi-year filter change intervals, is to use the US Air Purifiers filter change calendar tool. Simply enter your air purifier’s information and your email, and you’ll receive an automated email alert when it’s time for you to change your filter.

The service life of air purifier filters may vary, which is why it is important to know how often you need to replace filters in your equipment.
