How To Replace And Clean The Filter Of The Air Purifier?
Nov 12, 2018

In general, many purifiers now come with a reminder indicator for filter replacement. Follow the instructions of the lamp and change it. Some product manuals will also indicate the filter replacement cycle.

Secondly, you can observe whether the air volume of the air outlet is getting smaller; whether the noise is getting bigger; whether the air outlet has an odor; whether the color of the filter (especially HEPA) is black.

Three mainstream filters for filter air purifiers: pre-filter, activated carbon filter, HEPA filter.

The pre-filter (also called the pre-filter/primary filter) is the first filter of the air purifier and the most dirty one.

Cleaning cycle: Depending on the frequency of use, it is usually appropriate to clean 1-2 times a month.

Cleaning method: Use a rag/vacuum cleaner to remove dust.

Activated carbon filter, its main function is to remove volatile organic compounds such as formaldehyde, toluene, etc., as well as odor, deodorization and so on.

Cleaning cycle: It is recommended to clean and dry for at least 1 month for newly renovated users, southern rainy season and northern rainy season.

Cleaning method: dust on the surface of the activated carbon filter, can be wiped with a dry rag or cleaned with a vacuum cleaner.

High-efficiency air filter (HEPA) has the characteristics of large wind resistance, large dust holding capacity and high filtration precision.

Cleaning cycle: usually 1 time in 1-2 months depending on frequency of use and pollution status.

Use a vacuum cleaner to clean the surface of the filter, or wipe it gently with a dry cloth or paper towel, and dry it properly.
