Whole HouseWater Refining System
Soft, clean, truly refined water. Combines water softening and carbon filtration in one dual-tank system with a single control valve.
Same benefit as separate systems -- at a fraction of the cost.
Hydrotech HTO Up Flow Series
Rid your water of hardness minerals (calcium and magnesium) plus filter out bad tastes and odor caused by chlorine, chloramines or organic matter. The unique two tank system keeps the two media beds separate, allowing for more carbon contact which greatly improves removal. You get the same benefit as a separate water softener and whole-house carbon filter for a much lower price as the single control valve operates both systems.
IAPMO R&T Certified against NSF/ANSI 44 and CSA B483.1. Certified by IAPMO R&T to NSF/ANSI 42 for chlorine reduction.
How the HTO Combo SystemRefines Your Water
Two separate media tanks operated by a single control valve deliver complete water treatment
Catalytic Carbon Tank
Removes 97% of chlorine, chloramines, and organic compounds. Over 1.1 million gallon capacity. Separate tank allows for easy, cost-effective carbon replacement.
Softening Resin Tank
Aquafine 8% cation exchange resin removes hardness minerals (calcium and magnesium). Up Flow Regeneration saves salt and preserves unused resin.
Brine Tank
High-density polyethylene tank with lifetime warranty. Brine safety valve and plastic salt grid prevent bridging and overflow. Up to 420 lbs salt storage.
Because carbon typically needs replacement before softening resin, the separate tank design allows for easy, cost-effective maintenance
