These "whole house" Ametek cartridge filters are large enough to reduce any pressure drop problems that can be found when using smaller housings. The housings are of a commercial quality and will remove sediment from your water when supplied with our standard sediment filter cartridge. Cartridge filters will provide a pre-treatment filtration that can extend the life of many other water treatment products. When used in conjunction with a CAI Ultraviolet Disinfection System , these filter housings are a convenient place to add bleach solution when performing periodic disinfection of your homes piping.
