10 pcs Standard Size 4.5”x 20” ( 5 Micron) Sediment Filter. Filters sediment particles such as silt, sand, rust, dirt, and other undissolved particles.

Melt-blown Polypropylene Sediment Filters. The main function of a sediment filter is to remove large and fine particles from our drinking water, such as sand, dirt, silt, and rust particles.

Our Sediment filters are made of fine melted polypropylene, which is then blown and spun in a cylinder-like form.  These filters have a lower density at the surface of the filter with progressively higher density toward the center which enables to capture of particles throughout the entire filter depth.

This translates to a longer life and allows better performance of all the following filters, such as Carbon Block or GAC filters.

David Slusser (Hayward, California, United States)
go with the flow

I dried to find some discussion of stepping down from larger to smaller micron filters as I have three inline 4.5x20" canisters. I know everyone's water is different but I thought there might be a few thumbs rules. 'right now I use two of the three canisters with 5 micron filters. each year I change the filters I see a dirty first in line filter but not plugged up. What I want to maintain is good flow so maybe a 10 or 20 micron filter might be a good addition to my system.

Water Filters

We go through a lot of water filters because our well has fine sand in it. These filters sift out the sand and we change them monthly.
We really appreciate that they cost less and we can get them in quantities.
