Crystal Quest Whole House Reverse Osmosis System

The Ultimate Whole House Filtration ExperienceThe Crystal Quest Whole House Reverse Osmosis System is the highest-performing RO system on the market, backed by more than 25 years of experience. Engineered to deliver purified water throughout your entire home, every system is tested in-house before shipping and arrives fully operational, requiring minimal plumbing. With regular prefilter and membrane maintenance, these systems are built to last 15–20 years. All systems are modular, low-maintenance, and economical. Choose from 9 different flow rates to match your home's exact needs — from a single-bathroom home to a 5,000+ GPD commercial-scale property. Benefits Compact, space-saving design Easily accessible components Expandable and lightweight Fully equipped and customizable Low operational and maintenance costs Factory tested and preserved CE compliant Made in the USA ISO certified components Storage Tank Kit Components RO System — Commercial-grade, 300–7,000 GPD with integrated prefiltration to extend membrane life. Water Storage Tank — Atmospheric tank (165, 220, or 500 gallons) sized to your system and available space. Pump — Delivers purified water from the tank to your home on demand. Float Switches — Automatically cycles the RO system on/off based on tank water level. Note: Additional shipping charges may apply for orders with 500-gallon storage tanks. Optional Add-OnsUV Water Sterilizer (12 GPM)Adds an extra layer of protection against microbiological contamination downstream of the RO system. Alkalizing PostfilterEnhances alkalinity, mineralization, and oxidation of purified water before it enters your home. Remineralizer SystemAdds essential minerals back into purified water and adjusts pH to prevent damage to plumbing and fixtures from acidic RO water.
