Nairobi tap water carries chlorine, sediment, and varying mineral loads that you can taste and smell — and borehole water in many areas carries dissolved salts, rust, and hardness that no standard filter adequately removes. The Reverse Osmosis Water Purifier System 306 passes your water through a 0.0001 micron RO membrane that removes dissolved solids, heavy metals, bacteria, sediment, organic matter, and even salt — producing water so pure it fills a 200ml cup in 8 seconds and needs no storage tank on the counter. Wall-mounted with hot and cold dispensing taps, it is the complete home water solution for any Nairobi household or East African home that takes water quality seriously.

• 0.0001 Micron RO Membrane Removes Dissolved Salts, Metals, and Bacteria — The advanced composite RO membrane filters at 0.0001 microns — removing dissolved salts, rust, heavy metals, organic matter, bacteria, sediment, and fluoride that standard carbon or ceramic filters cannot capture. The result is water pure at a molecular level, safe for drinking, cooking, and baby formula without further treatment.
• Tankless Design Produces 300-500 Litres Daily and Fills a Cup in 8 Seconds — Unlike traditional RO systems that require a bulky storage tank and produce water slowly, this tankless system delivers purified water on demand — filling a 200ml cup in approximately 8 seconds at a daily output of 300-500 litres, enough for a medium to large household’s full daily water needs.
• Hot and Cold Dispensing — Replaces Both a Water Purifier and a Dispenser — Two push-button taps dispense hot water (pink indicator) and cold water (blue indicator) on demand — making this a complete water station that replaces a separate hot water dispenser, filter jug, and standard RO unit with a single wall-mounted appliance.
• Five-Stage Filtration Through Sediment, Carbon, and RO Filters — Water passes through five sequential treatment stages — sediment pre-filter, activated carbon, RO membrane, post-carbon, and mineral or UV stage — each removing a different category of contaminant, so the final water is not just filtered but genuinely purified for direct daily drinking.
• Eco-Friendly Reduced Waste Water Output — This system reduces water wastage by up to 600% compared to traditional RO systems by using waste water productively — suitable for mopping, car washing, and laundry. The twist-and-pull filter replacement design requires no tools and makes maintenance a simple self-service task.

This RO system is ideal for Nairobi households on borehole water, water tanks, or tap supply with taste or quality concerns — anyone who currently spends money on 20-litre bottled water deliveries and wants a one-time installation that produces equivalent quality water permanently. It suits families with young children where water safety is a non-negotiable daily priority. It is also the right choice for anyone in areas with hard, salty, or rust-affected water where no standard filter is adequate — only an RO membrane removes dissolved salts at the molecular level.

Frequently Asked Questions

Q: Does this water purifier work on standard Nairobi tap water, or is it only for borehole water?

It works on both. Municipal tap water, borehole water, water from rooftop tanks, and hard or salty water are all suitable input sources. The 5-stage filtration handles the sediment and chlorine typical of municipal supply, while the RO membrane addresses the dissolved minerals and salts found in borehole and hard water sources across Kenya.

Q: How often do the filters need to be replaced?

Pre-filters (sediment and carbon) typically need replacement every 6-12 months depending on input water quality. The RO membrane lasts 18-24 months under normal use. The exact interval depends on your water source’s TDS level and daily usage volume — harder or more contaminated source water accelerates filter consumption.

Q: Does installation require a plumber, and is it possible to do it yourself?

The system mounts to the wall and connects to your existing water supply line. Basic installation is within the ability of a handy homeowner or casual fundi — the filter replacement mechanism is explicitly tool-free. For the initial water line connection, a plumber’s visit for one to two hours is recommended to ensure a leak-free fitting.
