MB-5, Melt Blown 5 Mic. 9 3/4, SC25-10005

Nelsen Big-Blue Melt-Blown Poly Sediment filters are constructed with 4-layers of different micron ratings. The graded densities of layers capture particles throughout the entire cross section of the cartridge reducing surface binding or buildup.

That sediment buildup results in greater pressure drops and quicker replacement of the cartridge. The finer the particle the deeper through the surface of the cartridge it travels. Example: a 5 micron rated cartridge has these four layer densities - Inside Layer - 5 micron, 2nd Layer - 10 micron, 3rd Layer - 25 micron, Outer Layer - 50 micron.

The Nelsen Big-Blue Sediment filters are made from 100% high purity polypropylene, have good chemical resistance are not prone to bacteria attack. They are available in 1, 5, 10 & 25 micron rates and come in 10 and 20 inch lengths.

An economical alternative filter to the NSF approved. These filters are made from 100% high purity polypropylene, have good chemical resistance are not prone to bacteria attack.
