GRO 5 Stage, 75 GPD Freshpoint RO

Concern over PFAS in drinking water has put high-performance reverse osmosis front and center, and the Pentair FreshPoint GRO 5-Stage 75 GPD RO System answers that concern directly. Certified to reduce up to 99.7% of total PFAS, this under-sink system targets the so-called forever chemicals along with a wide spectrum of other contaminants found in tap water, making it a strong choice for families who want serious, verified protection at the kitchen faucet.

Five stages of treatment, anchored by Pentair's high-efficiency GRO membrane, work together to reduce more than 90% of contaminants while producing up to 75 gallons of purified water per day. Color-coded cartridges keep the filter sequence correct, and effortless click-in change-outs make routine maintenance something any homeowner can handle without tools or guesswork. The high-efficiency membrane technology also helps the system make the most of every gallon it treats.

Features that make ownership easy

• Certified to reduce up to 99.7% of total PFAS (test mixture of PFOA, PFOS, PFHxS, PFNA, PFHpA, PFBS, and PFDA)
• Reduces more than 90% of contaminants found in water
• High-efficiency membrane delivers up to 75 gallons per day
• Color-coded, click-in cartridges maintain proper filter order
• 3/8" push fittings for fast, tool-light installation
• Integrated check valves allow change-outs without shutting off the cold water line

The system arrives ready to install with an air gap side faucet, a complete installation kit, a 4.4-gallon storage tank, and an installation and operation manual. Thoughtful engineering shows throughout: the integrated check valves mean you do not need to shut off the cold water supply to swap cartridges, and the mechanical-assist lever lets the unit be mounted flush to the baseboard since cartridges push straight out rather than dropping down. Whether your goal is reducing PFAS, dissolved solids, chlorine taste, or all of the above, this FreshPoint GRO system pairs certified, lab-verified performance with maintenance that takes only minutes a year.

For families researching how to address PFAS, dissolved solids, and chlorine taste in one step, this certified five-stage system offers a compelling combination of verified performance and homeowner-friendly maintenance. It turns the kitchen tap into a dependable source of cleaner, better-tasting water while keeping cartridge changes to a quick, tool-free routine.
