How Often Should You Change the Filters in Your HEPA Filter Air Purifier?

When it comes to air purifiers, the type of filter you have and the environment you live in will determine how often you need to replace the filters. Generally speaking, replaceable HEPA filters should be changed every 6 to 12 months, depending on air quality and environmental factors. Carbon prefilters should be replaced every 3 months, depending on air quality and environmental factors. For example, Sqair HEPA filters should be changed every 1400 hours, which is equivalent to 6 months if used at a high temperature for 8 hours a day.Air purifiers come with a variety of filters and components that serve different purposes.

AllerAir purifiers, for instance, come with a prefilter, an activated carbon filter and either a large true HEPA filter for medical use or a Super HEPA filter. The polluted air passes through the bottom of the unit and is filtered through each of these components before exiting through the top. Additionally, UV-C light can also be added to any air purifier to kill viruses, bacteria, germs and mold.If you use your air purifier in a commercial environment, it's best to change the activated carbon filter and the HEPA or Super HEPA filter every year. All of the purifiers we offer are made in Canada with Canadian parts and come with a 10-year warranty.

To take full advantage of an air purifier's benefits, it's best to replace the filters on schedule or as soon as you notice a deterioration in air quality. Regularly replacing the filters extends the life of the unit and ensures that it continues to operate at optimal efficiency. Unfortunately, once a standard HEPA filter gets dirty, cleaning isn't an option.How often you should change your HEPA filter depends on your exact use and air pollution circumstances. Air quality will decrease with the frequency with which the air purifier cleans a room every hour.

If you want to get optimal performance out of your air purifier, it's hard to avoid filter replacement times and costs.
