Pentair WS-20BB Big Blue Water Softener Cartridge, 20 x 4.5

Pentair's Pentek WS Series Cartridges have been specifically designed to ensure the most effective contact between water and resin surfaces, enabling maximum ion exchange. These cartridges feature an internal expansion pad that minimizes channeling and a post-filter that eliminates any possibility of bypass. Their unique design allows them to deliver softened product water efficiently, thanks to the use of sodium-based, non-solvent rinsed softening resin.

The convenience and practicality of the cartridge style design mean that these units are an ideal solution for delivering softened water in order to protect sensitive water delivery equipment. Medical equipment, coffee and espresso appliances, low-volume beverage equipment, and commercial food service machines all benefit from the superior performance and outstanding protection provided by our Water Softening Cartridges.

With a 4,500 grain capacity, these cartridges are able to reduce hardness, minerals, and scale deposits in low flow rate applications effectively. They are compatible with all 20" Big Blue or other heavy-duty housings, making them a versatile choice. Our water softener cartridges can replace any 20" x 4.5" cartridge with ease.

Choose Pentair Pentek WS Series Cartridges for a reliable and efficient solution to your water softening needs. These cartridges provide exceptional performance, outstanding protection, and maximum life grain capacity thanks to their utilization of single-use resin technologies.
