This build-up can hamper the efficiency of the air cleaner and trap dust and bacteria. Cleaning your air purifier can be completed in less than an hour with readily available household items. This is a maintenance task that should be done at least once a year. In this tutorial, we will see how to clean Honeywell air purifier filter.

What kind of filters do Honeywell air purifiers feature?

How to Clean Honeywell Air Purifier Filter?

Honeywell air purifiers are effective against up to 99.97% of microallergens in the air, thanks to their filtration system.

To achieve this effect, the company relies on the following filters: coarse particle pre-filter, activated carbon filter, particularly useful for gases and odors, HEPA filter against up to 99.97% of all 0.3 micron particles, like the Honeywell HPA300 features.

Your air purifier will likely carry at least two of these filters: a pre-filter, which traps large particles such as animal hair, and the main filter, which traps small pollutants. The Honeywell HPA300, for example, features the carbon pre-filter and the HEPA filter. The main filters in Honeywell air purifiers can either be a HEPA, ifD, or HEPA clean filter which can capture smaller microscopic particles.

You should look for an air purifier such as the Honeywell 50250-S that uses a True HEPA (High Efficiency Particulate Air). The filter in this type of device is the standard recommended by both the European Union and the World Health Organization (WHO). HEPA filters retain 99.95% (EU) or 99.97% (US standard) of particles 0.3 microns (millionth of a meter) or larger.

Frequency of filter cleaning

While Honeywell recommended that you change the filters of a Honeywell air purifier approximately every 6 to 12 months, the washable pre-filters should be washed once in a month and the main filter should be washed once in three months.
