What is the filter aperture of the water purifier pre-pp cotton and? Don't pp cotton. can you install backwashing front? There are two kinds of PP cotton filtration accuracy: 1 um and 5 uM. the reverse filtering accuracy is not as high as that. pp cotton is not expensive, or it is not convenient to figure it out. The diameter of PP cotton is about 1 micron, and the difference may be larger. It is not very expensive to change pp cotton. it may be about 20 yuan to go to the wholesale market. it is good to change one in three to six months. besides, carbon is also to be changed, carbon adsorption is to lose activity to a certain extent. it is necessary to change it anyway. it does not take much time to change it together. if it is manual, you must also rush frequently.
