The HydroTAC Whole-Home Water Filter & Conditioner is a compact whole-home water filtration and conditioning system designed to help reduce scale buildup, chlorine, sediment, and other common water contaminants without the use of salt or harsh chemicals.
Using advanced Template Assisted Crystallization (TAC®) technology combined with high-flow activated carbon filtration, the HydroTAC® system helps protect plumbing, fixtures, appliances, and water heaters while improving overall water quality throughout your home.
Unlike traditional salt-based softeners, HydroTAC® conditions water without adding sodium or producing wastewater, making it a low-maintenance and environmentally friendly alternative.
Key Features
• Salt-free water conditioning technology
• Helps reduce and prevent scale buildup
• Dual-stage high-flow filtration system
• Activated carbon filtration for chlorine and chemical reduction
• Helps reduce PFAS compounds
• No salt, chemicals, or wastewater required
• Leaves beneficial minerals in the water
• Compact whole-home system design
• Low-maintenance operation with long filter life
Advanced TAC® Scale Prevention Technology
HydroTAC® uses proven Template Assisted Crystallization (TAC®) technology to convert hardness minerals into harmless microscopic crystals that are less likely to adhere to plumbing surfaces.
Independent testing has shown HydroTAC® can help reduce and prevent up to 99.6% of scale buildup while also helping remove existing scale deposits over time.
Dual-Stage Whole Home Filtration
The integrated dual-stage filtration system combines TAC® conditioning with a high-performance radial flow activated carbon block filter to help reduce:
• Chlorine taste and odor
• Sediment
• PFAS compounds
• Other common chemical contaminants
Activated carbon treatment is one of the most widely studied and proven technologies for PFAS reduction.
Benefits of HydroTAC®
• No salt or corrosive chemicals required
• No wastewater during operation
• Helps extend the life of appliances and plumbing
• Leaves healthy minerals in the water
• Helps reduce existing scale deposits
• Lower maintenance requirements compared to traditional softeners
• Filter life up to 3 years under normal conditions
