As is known to all, now standard configuration: pure water machine is commonly magnitude of 5 & mu;

After the activated carbon.
Former triple filter is in the service of the RO membrane, as the pretreatment of raw water, in order to increase the service life of RO membrane, the pure water machine of RO membrane before a filter or 1 & mu;
MPP cotton is better?
for three reasons: first, 1 & mu; MPP cotton is 1 micron filter filtration precision, greater than 1 & mu; M of sediment particles, bacteria, scale and other harmful substances can roundly eliminate, in the first 5 & mu; M still can rise to protect the RO membrane filter loss effect, reducing the probability of RO membrane contaminated.
2, can effectively prevent internal activated carbon powder into the RO membrane, protect the RO membrane decrease as far as possible the entry of activated carbon powder, prolong its service life. Because before installing the activated carbon filter we wash and clean, also can have charcoal powder flow out, before the RO membrane with a 1 & mu; M filter can have barrier effect, greatly reducing the possibility of man-made pollution of RO membrane.
3, if the third level is the massive compression or sintering CTO of activated carbon, five three filter is activated carbon filter, activated carbon filter for repeated use, not only waste resources, also increase the cost and lose its proper role. And the second level is generally granular activated carbon, installation time need to wash, often cause a lot of blackwater, and easy to wipe clean. If activated carbon to compress the blackwater problem is solved, does not increase the burden of the third grade PP cotton.
pure water machine filter cartridge is the period of using, fiber filter can use commonly 3 - 6 months, activated carbon filter 6 - in general 12 months, their life is totally depends on the size of the local water quality, water pressure and water consumption. In the regular replacement of filter, reverse osmosis membrane guarantee period is one year, more than 90% removal efficiency.
