Reverse Osmosis Water Purification · Nairobi & Nationwide
Pure, contaminant-free water, straight from your kitchen tap.
Book professional reverse osmosis under-sink water purifier installation and stop worrying about what's in your drinking water. Our certified technicians fit multi-stage RO membrane systems — with storage tank and dedicated tap — neatly under your sink, done in one visit.
Why install one
Everything a bottled-water dispenser does — without the bottles.
Removes dissolved salts & contaminants
The RO membrane filters out chlorine, sediment, dissolved salts (TDS), heavy metals and most bacteria before water reaches your glass.
Pays for itself
Cut the recurring cost of bottled and dispenser water with one RO system fitted for the long term.
Completely hidden
The membrane unit and storage tank fit inside your existing under-sink cabinet — no counter space lost, no visible units.
Better-tasting everything
Purer water improves the taste of drinking water, tea, coffee and cooking.
Protects your appliances
Removing dissolved hardness minerals reduces limescale build-up in kettles and appliances fed from the purified line.
Best for hard & borehole water
RO is the most effective option for mains tap water, borehole supply, or tank water with high dissolved solids.
The installation process
From booking to your first glass of purified water.
Five steps, usually completed in a single visit.
Book & assess
Book online, by phone or WhatsApp. We review your water source, TDS level, and kitchen layout.
Match the RO system
We recommend a 4, 5, or 6-stage reverse osmosis system based on your water quality.
Fit the unit
A certified plumber connects the pre-filters, RO membrane, storage tank and drain line, then fits your dedicated purified-water tap.
Test & verify
Full pressure test for leaks, plus an output TDS check before we hand over.
Handover & care plan
A quick walkthrough and a membrane and cartridge replacement schedule to keep it performing.

Frequently asked
Questions homeowners ask before booking.
Most installations are completed within 1 to 2 hours, provided there's existing plumbing access and room for the storage tank under your kitchen sink.
Yes. RO units and their compact storage tanks are built to fit standard kitchen cabinets. We assess your sink and cabinet space during booking to confirm the right system size.
A carbon filter removes chlorine, odour and sediment. Reverse osmosis adds a fine membrane that also removes dissolved salts (TDS), heavy metals and most bacteria — producing significantly higher-purity water, especially important for borehole or hard water.
Yes. Pre-filter cartridges typically need replacement every 6 to 12 months, and the RO membrane every 12 to 24 months, depending on usage and water quality. We provide a maintenance schedule and replacement service.
Yes. Once installed and maintained on schedule, reverse osmosis purified water is safe for drinking, cooking, and preparing beverages directly from the dedicated purified-water tap.
