Whole-House Filtration
Point-of-entry filtration for sediment, chlorine/chloramine strategy, carbon media, KDF options, PFAS upgrades, bypasses, gauges, and premium plumbing.
Municipal Compliance Is Not Household Optimization.
Kensico-region water is not the same as groundwater, well water, or generic municipal water in other parts of Westchester. The route from reservoir to treatment to mains to the home creates different design problems than a one-size cartridge filter can solve.
What the municipality does
Municipal water is treated for public distribution and regulatory compliance. That does not mean it is optimized for taste, ice, coffee, shower exposure, appliances, black vehicles, glass, or high-purity use inside one specific property.
What RFPure Water designs
RFPure Water designs the actual system sequence: sediment, carbon, catalytic carbon, KDF, PFAS media, RO membrane, DI polishing, storage, pressure, flow rate, bypass piping, shutoffs, and fixture delivery.
Build Around How You Use Water.
The correct system depends on whether the goal is drinking water, shower water, whole-house protection, vehicle rinse water, laboratory water, or controlled fluid delivery.
Reverse Osmosis Drinking Water
Premium RO systems for drinking, cooking, ice, coffee, refrigerator feed, remineralization, storage expansion, leak control, and pressure performance.
Purified Shower Systems
Not a screw-on shower filter. Designed purified-water shower systems using RO storage, pressure planning, diverter logic, and premium installation.
Spotless Vehicle Rinse
DI and RO/DI rinse stations for black vehicles, glass, chrome, solar panels, exterior fixtures, garage walls, driveway wash stations, and hose bibb integration.
The Science Behind Your Water.
A serious water system is a sequence, not one filter. Each contaminant class requires different media, contact time, pressure, storage, and final delivery logic.
This is not the company to contact for a $700 RO system.
RFPure Water is for customers who want licensed plumbing, engineered filtration, premium components, correct pressure and storage design, and transparent pricing before the work begins.
Sediment / RustParticles, turbidity, pipe debris, and visible water quality problems.
Chlorine / ChloramineDisinfection residuals need carbon strategy, not just a sediment filter.
Disinfection ByproductsDBP concerns require media selection and point-of-use planning.
PFAS / Emerging ContaminantsRequire targeted media, RO, or staged treatment depending on system goal.
Metals / Manganese / IronMay involve source water, street mains, building plumbing, or premise piping.
TDS / SpottingVehicle rinse, glass, and solar applications often need DI or RO/DI polishing.
Transparent Pricing Starts With the System Type.
Pricing is shown early to avoid wasted visits. Final price depends on photos, pipe size, shutoff condition, media selection, pressure, storage, and installation complexity.

Designed by a Fluid-Systems Inventor. Installed by a Licensed Westchester Master Plumber.
RFPure Water is built around two people responsible for the design and installation quality: Harry Otto and Robert Ferro.
Robert Ferro
Licensed Westchester Master Plumber since 2001
Robert Ferro’s experience ranges from Park Avenue work in New York City to 16,000-square-foot homes in Scarsdale. When permitting, inspections, mechanical-room layout, concealed plumbing, and code compliance matter, Robert is responsible for the licensed plumbing side of the project.
Harry Otto
RO water engineer / fluid-systems inventor
Harry Otto designs the RO, filtration, pressure, storage, flow-rate, selective delivery, and contaminant-removal logic. His patent portfolio involves pressure-based liquid handling, high-speed dispensing, sealed liquid paths, and modular scalable fluid systems.
Patented Fluid-Systems Language Opens Technical Doors.
The patent portfolio supports a higher-level discussion with laboratories, pharma users, beverage companies, cosmetic manufacturers, specialty manufacturers, and technical facilities that need pressure, purity, storage, routing, material compatibility, and controlled delivery.
Useful technical terms: pressure-regulated liquid systems, selective liquid dispensing, controlled fluid delivery, metered fluid movement, pressurized liquid storage, sealed liquid-path architecture, non-pump liquid transport, solenoid-controlled flow, pressure-vs-time delivery logic, modular scalable fluid systems, RO/DI polishing, and high-purity water routing.
