OnlyPure Reverse Osmosis System (OPRO600-B, Tankless, Alkaline Filter)

What contaminants does this system remove?

The OnlyPure system removes over 1000 different contaminants including 93% of total dissolved solids. Specific contaminants eliminated include lead, chlorine, mercury, cadmium, arsenic, sand, rust and various organic compounds. The NSF ANSI 58/372 certification confirms its effectiveness against these harmful substances. The multi-stage filtration process ensures comprehensive water purification whilst the alkaline stage adds back beneficial minerals.

How often do the filters need replacing?

The carbon and alkaline filter (PCT filter) requires replacement every 12 months under normal usage conditions. The reverse osmosis membrane typically lasts 24 months depending on your water quality and usage volume. The system's smart faucet display monitors filter life and alerts you when replacement is needed. Filter replacement is straightforward with twist-and-lock mechanisms requiring no tools.

What is the installation process like?

Installation is designed for DIY completion with included components and instructions. The system connects to your cold water supply under the sink and requires a standard electrical outlet. You'll need to drill one hole in your sink or countertop for the faucet. Most installations take 2-3 hours. The system includes all necessary fittings, tubing and mounting hardware. Professional installation is available if preferred.

How does the alkaline enhancement work?

After reverse osmosis removes contaminants, the final alkaline filter adds back essential minerals like calcium, magnesium and potassium. This process raises the water's pH to above 8.5, creating alkaline water. The minerals improve taste whilst potentially offering health benefits like better hydration and pH balance. The alkaline stage doesn't compromise the purification achieved in earlier stages.

What are the system's dimensions and power requirements?

The system measures 43.2cm length x 13.7cm width x 40.6cm height, fitting easily under most kitchen sinks. It requires a standard electrical connection and operates on mains power. The tankless design eliminates the need for a large storage tank, maximising under-sink space. The compact footprint doesn't affect the 600 GPD production capacity or filtration effectiveness.

How much water does the system waste?

The system operates with an efficient 2:1 pure to drain ratio, producing 2 litres of clean water for every 1 litre sent to drain. This is significantly more efficient than traditional RO systems that often waste 3-4 litres for every litre produced. The improved efficiency reduces water bills and environmental impact whilst maintaining excellent purification performance.

Can this system handle high TDS water?

The system effectively processes water with TDS levels up to 300 PPM (parts per million). For water with higher TDS levels, pre-filtration may be recommended to extend membrane life. The smart faucet displays real-time TDS readings of both input and output water, allowing you to monitor system performance. The 93% TDS reduction rate remains consistent across the supported TDS range.

What maintenance is required beyond filter changes?

Beyond scheduled filter replacements, the system requires minimal maintenance. The smart display monitors system performance and alerts you to any issues. Periodic sanitisation is recommended every 6-12 months using standard RO system sanitising solutions. The system's self-monitoring capabilities reduce the need for manual testing. All maintenance procedures are detailed in the included manual with step-by-step instructions.
