iSpring F2WGB21B Whole House 4.5"x10" Water Filtration High Capacity Sediment and CTO Carbon Block Water Filter Replacement Cartridge Pack Set, Model: WGB21B

The iSpring whole house filter is extremely effective in filtering water, specifically well water in southern Alberta. Changing filters was simple and quick. Although it was helpful that the person that changed the filter was the one that installed the system. For my part, it was ordering the system and filters and communicating with Francis with iSpring. Francis provided exceptional service and gave me helpful and professional advice on more than one occasion. Much appreciated! Thank you again. The attached "after" photo shows how effective the filter is!

Excelentes filtros para mi cisterna cumplen con su funcion

I’ve been using these filters for years with great results. Always fit perfectly, they do a great job of filtering with an odor free result. The flow rate/psi differential stays at ~8 to 10 psi until they need changing out. They last a long time. They never come apart and are simple to replace.

Good replacement filters for our water treatment system.

Muy practico diseño, de facil instalacion y muy buena calidad de agua filtrada, el sistema lo tengo instalado a la entrada de mi tinaco de agua principal, el agua que obtengo en el sistema sale sin sabor y libre de sedimentos.
