first, check the air filter of the purification project to see if there is no black or black. if the air filter has a very obvious black appearance, then we need to replace the air filter. generally speaking, if there is a problem with the air filter, it will deflate. once this situation is found, it needs to be replaced. if we find that the effect of air filtration is not particularly good, but there is no problem in itself, we can see that there is a lot of dust around the filter, because if too much dust will also cause problems in our filter, we only need to clean the air filter at this time is good, but if it is cleaned, the effect is not very good. you need to change it.
