    We encourage you to seek local expertise before deciding on a filtration or softening system. The composition of water and water pressure can vary so greatly from one location to another that you may require a different level of softening, filtration, or purification than our kits provide (ours is designed for hard water). Regardless of water quality, some filter type is always required to keep solids out of the machine.  It includes everything needed to connect the cold water source under your sink to the braided line included with your espresso machine.

    The cartridge in this kit is a Homeland filter. Homeland is a co-op of Holiday House Distributing and Omnipure Filter Company. This cartridge filters taste, odor, chlorine, limescale, and particulates. Its service life is 1,700 grains or roughly 1,000 gallons with a flow rate of 2 gallons per minute(GPM). 

    The HCWS filter is a 10-micron level Granular activated carbon cartridge. The Granule Carbon removes taste, odor, and chlorine from water and particulates and has a scale inhibitor and softener.
