20" BB Dual Gradient Polypropylene Sediment Filter 150/50 mic 12 Months A colorimetric test strip is

A colorimetric test strip is used to take the guesswork out of accurate arsenic measurement

It can also be used with UV water treatment system

NOTE: This controller is used for all SQ-P

As water passes from the outer surfaces into the center of the cartridge

which provides a consistent dispersion of water flow across the filter resulting in cleaner water and very lower pressure drop

20" BB Dual Gradient Polypropylene Sediment Filter 150/50 mic 12 Months A colorimetric test strip isDual Gradient Density Filters work as a pre and post filter all in one, eliminating the need for step down filtration systems in your home. The outer layer is a 150 micron pre filter that takes out larger sediment, thus reducing the load on the 50 micron inner layer post filter allowing it to operate more efficiently and consistently. The pure polypropylene construction makes it resistant to chemicals and corrosion. Features: Will not add taste, odor,
