Vacuums: Tips on How Often to Change a HEPA Filter

The frequency of the HEPA filter changes will depend on a myriad of factors, including how often you use your machine, the indoor environment, the condition of the air con and even the location.

Nonetheless, some of the filters will go up to two years without requiring change.

If you're still unsure on when or whether it's the right time to change your HEPA filter, remember that you will not lose anything by playing safe and changing your HEPA filter regularly.

Nonetheless, here are some a few pointers to guide you on how often you should change your HEPA filters.

Residential Setting

If you’re using a vacuum with a HEPA filter is strictly a residential setting, the filter should last anywhere from 2-3 years before needing a replacement.

While the period will depend on how much you use it, regular cleaning usage should last anywhere from 24 to 36 months.

Commercial Use

If you are using your vacuum in a commercial setting such as an office, the filter should be changed more frequently.

If it's used daily, it should be checked at least every six months.

If the filter looks heavily soiled, it should be changed even more regularly; otherwise, the filter should be changed at least once a year.

In a commercial setting, we recommend that you perform a DOP Testing | Dispersed Oil Particulate Test to ascertain the integrity/efficiency of HEP of your filter. This will ensure that all your workers are protected and only inhale quality indoor air.

If you Smell Must

While it’s good to know how long a vacuum can last, a musty smell is an indicator that your HEPA filters need change.

In any case, the musty smell indicates that the integrity of your HEPA filter has been compromised and it’s no longer working efficiently.

Carbon Filters

Some of the advanced HEPA filtration systems usually come with an additional layer of filtration in the form of carbon pre-filter.

Carbon pre-filters are excellent at removing the odors from the air.

Similar to the regular HEPA filters, the carbon filters should be removed at least annually for commercial uses, and one in 2 or 3 years for residential use.

Others

If your filter has a pre-filter that is designed to capture the large particulate matter, you should check the filter after every three to four months.

Also, if the filter or the housing that holds the filter ever gets damaged, you should change the filter as well.

During replacement, we recommend that you call a professional to make the change.
