The function of the HEPA filter is to filter out small particles (commonly known as PM2.5), bacteria, and various allergens. It can be said to be the core group of the filter. I believe many people are concerned about whether this key core filter can be cleaned?
Unfortunately, we regret to inform you that most air purifiers use HEPA filters that cannot be cleaned by water washing. This is also due to the fact that HEPA materials themselves are made of paper and generally cannot be washed with water.
What are the consequences after cleaning? The president can tell everyone that after cleaning the HEPA filter with water, it may appear much cleaner on the surface (at least a little whiter), but the direct impact is on the purification efficiency. In most cases, the HEPA purification efficiency after cleaning does not increase but decreases.
The function of activated carbon filter is well-known, mainly removing volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene, and pollutants in the air. It also plays a role in deodorization and odor removal.
Can the activated carbon filter be cleaned? First of all, the president's answer to everyone is yes. However, in general, cleaning and maintaining activated carbon filters does not require so much effort. The simplest way is to expose the filter to sunlight for a day.
If you want to wash the activated carbon filter with water, first the water temperature should not exceed 50 degrees Celsius to ensure that the activated carbon will not deform when exposed to high temperatures. In addition, neutral detergent can be added for cleaning, and strong acid and strong alkaline detergents should not be used to avoid chemical damage.
