RO membrane of a filter and 1 micron pp filter before choosing the three factors of

for three reasons:

1. Can effectively prevent internal activated carbon powder into the RO membrane, protect the RO membrane to minimize 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 micron filter can have barrier effect, greatly reducing the possibility of man-made pollution of RO membrane.

2。 Pp filter 1 micron accuracy of 1 micron, greater than 1 micron sediment particles, bacteria, scale can be qualified to remove harmful substances, such as during the first 5 micron filter loss function still can rise to protect the RO membrane, reduce the probability of RO membrane polluted.

3。 If the third pole is activated carbon block compression, 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.

4。 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, will not increase the burden of the third pole PP cotton.
