Question 2: How to clean the HEPA filter? I don't know where the students who said "h 10 can't be washed, but H 12 H 13 can" came from.
As a precision material, HEPA filter is more efficient and cannot 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%.

Question 8: How to clean the air-conditioning filter element is very necessary, because a lot of dust accumulates in the air-conditioning filter element, which is not only harmful to human body, but also hinders air circulation and refrigeration effect. So how do you clean the air conditioner filter? Rinse the filter with plenty of flowing water, dry it and put it back. If there is not much oil in the cover, you can rinse it with clear water and then brush it with a clean soft brush. During use, in order to ensure fresh air, it should be cleaned every 15 days.
Generally speaking, you don't have to clean yourself. Because it needs professional cleaning and maintenance, and because the current air conditioners are all heat pump units, the indoor evaporator and outdoor condenser will be replaced in summer and winter, especially in the defrosting process, the evaporator can be self-cleaned to a certain extent. The filter screen should be cleaned frequently, which is beneficial to the improvement of air quality and the air conditioning unit itself. Please see below! ! !
※ 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".
