How to clean HEPA filter
Students who say "h 10 can't be washed, but H 12 H 13 can" don't know where the basis comes from.
As a precision material, HEPA filter is more efficient and can't be cleaned. Because the efficiency of HEPA is reduced after use, although the air purifier is still running with a filter, it may have no purification ability.
Especially, in order to increase the filtration efficiency, some HEPA materials are electret-treated materials with static electricity, which can't be washed with water. In the process of use, the static electricity of this material will be less and less, and the efficiency will be lower and lower.
In other words, HEPA material is a consumable and cannot be recovered after use. Just like toilet paper, no one will clean it before using it, right? Believe me, the bacteria on HEPA filter net are not necessarily cleaner than toilet paper after several months of use. . . . . .
You can read the article "How often does HEPA filter of air purifier need to be replaced?"154.
Moreover, not only the HEPA filter element in the purifier can't be cleaned, but also the HEPA filter element in the automobile air conditioner can't be cleaned. The filtration accuracy of this improved PM2.5 vehicle filter is also very high, with a removal rate of over 99%.

Cleaning method of air filter screen
Methods/steps
1, the front filter (usually the back cover of the chassis) has been used for a long time, which will gather some dust, thus affecting the effect of air intake and air purification.

2, filters, some filters need to be exposed to the sun regularly, so as to better maintain the purification efficiency, such as activated carbon filters.
3. Deodorizing filter screen, the deodorizing filter screen of a few brands of air purifiers, in order to reach the technical level of cleanability, can maintain the purification efficiency through cleaning and shorten the cycle of replacing the filter screen.
4. Generally, the ionizer is built-in and does not need cleaning. A better ionizer is more efficient.

※ How to clean the air conditioner※ The air conditioner mainly cleans the filter screen of three parts, the filter screen of the evaporating dish and the filter screen of the cooler. Evaporating dish and cold detector directly lead to refrigeration effect, and there is a layer of scale on it, which should be cleaned with clear water. Clean the air conditioner, mainly by cleaning the air conditioner panel and dust filter regularly. So, how to operate to achieve the best cleaning effect?
1. First, remove the dust filter screen according to the instructions, and be careful not to touch the metal part of the indoor unit during removal to prevent scratching.

Cleaning method
The cleaning of air conditioner should include three parts: the first part is the shell of air conditioner and the * * * part, which is easy to be polluted; The cleaning of the second filter is the most important part of the core; The third condenser and evaporator, relatively rare, combined with maintenance, is equivalent to cleaning a small system. They are relatively large "operations" and often appear in old air conditioners or "special price machines" and "inferior machines". Quite a few of these air conditioners have no cleaning and maintenance value, so I won't go into details. The cleaning of the air conditioner shell and corresponding components is very simple. As long as a little soap powder and detergent are added to the clean water, or special air-conditioning cleaning liquid, a considerable part of air conditioners can be cleaned, which meets the cleaning operation requirements. As for the cleaning of household air conditioners, the key part is the cleaning of filter screens. First, open the cover of the air conditioner, take out the filter screen and brush it with a clean filter screen to clean most of the dirt attached to the filter screen. Then soak in the mixed solution containing special air conditioner cleaning solution or self-made cleaning solution or detergent and soap powder for 65,438+00-20 minutes, depending on the dirt on the filter screen. After soaking, gently brush the filter screen with a bottle brush. If it is normal, you can sign for it, and the cleaning work is over. Cleaning the household air conditioner is beneficial to improve the refrigeration efficiency; It is beneficial to improve the refrigeration effect, prolong the service life of household air-conditioning equipment, improve the energy-saving effect and benefit the health of users. The effect is healthier and more ideal than "healthy air conditioning".
How to clean the floor heating filter by yourself?
Step 1: Close the main water inlet valve and water outlet valve, then insert the pipe for drainage into the water outlet and exhaust valve, then open the water outlet and exhaust valve to release the pressure in the geothermal pipeline, then open the filter valve with a wrench, take it down and clean it carefully, and finally restore it to its original state. The next step is to discharge the sewage in the geothermal pipeline: step one, close the main backwater valve, open the main intake valve, then close the small valves of each branch pipe, then insert the waterproof pipe into the backwater vent valve, and finally open the small valves of each branch pipe one by one to drain water one by one until the sewage disappears.
