Tboy,
Are you talking about the whole house system. I got mine from RainSoft it included the main filtration the computer controller to monitor water usage to activate the salt brine flush of the DI Resin on the main system, the Carbon Tower filter (18x54) no small critter and the the RO drinking water with pressure tank and faucet also ran to my ice maker. It is abit pricey but how can you put a price on your health.
