It hooks up to the faucet, and the water goes through a box, which sits on the counter. The water is filtered through, and then is poured through the machine. You can add a hose, to fill up five gallon tanks. Father Voigt bought one for the seminary in Boston, so the seminarians and priests can have good, filtered water, free of contaminants.
I sent Father an email about which model he purchased. I will post the information as soon as I get it. God bless.
