- American Revolution 750 Commercial RO — 750 GPD light commercial RO for restaurants and small food service operations.
- Raptor Lite Food Service RO — Compact RO for food service environments. Evaluated against full commercial systems on flow rate and footprint tradeoffs.
Water softeners
- US Water Systems Synergy Twin-Alternating Softener — Twin-tank commercial softener for 24/7 hardness-free water. Best for restaurants, hotels, and operations that cannot tolerate regeneration downtime.
- US Water Systems Maverick Commercial Softener — Single-tank demand-initiated softener for smaller commercial loads where the Synergy is oversized.
Iron and contaminant filters
- US Water Systems Matrixx InFusion — Peroxide injection iron and sulfur removal for high-load well water applications. Handles 7+ PPM iron and simultaneous H2S where air injection systems fall short.
- Matrixx DROP Bodyguard Plus Backwashing Carbon Filter — Dual GAC + catalytic carbon backwashing filter in 1.25″ and 1.5″ commercial configurations. Removes chlorine, chloramine, THMs, PFAS, VOCs, and organic contaminants. DROP WiFi smart valve. The correct pre-treatment stage before any commercial RO or softener on municipal water.
- Harmsco HUR-40-HP Hurricane Filter — High-flow commercial wound filter housing for sediment and particulate prefiltration ahead of softeners and RO systems.
Multi-stage commercial filtration
