Domestic RO systems
A multi-stage under-sink system feeding a dedicated drinking tap. Sized to what your supply actually carries, fitted and serviced by the people who built it.

Output is rated in gallons per day. The right one depends on household size and what your supply carries — a TDS reading settles it in minutes.

Treatment stages
Nine stages between the tap and the glass. Not every system carries all nine — the ones your supply needs are fitted, and the rest are not sold to you.
Stage 01
Tap or bore water enters the unit.
Stage 02
Sand, dirt, rust and visible particles.
Stage 03
Chlorine, odour and organic chemicals.
Stage 04
Fine particles down to one micron.
Stage 05
Raises pressure to 60–120 psi.
Stage 06
Removes 90–99% of dissolved solids.
Stage 07
Polishes taste on the way out.
Stage 08
Fitted where the supply warrants it
Bacteria and viruses, where the supply warrants it.
Stage 09
Pressure tank feeding a dedicated tap.
Products & components
The consumables and components a domestic system runs on, with current website prices. Ask for anything not listed.
Carbon Block Filter Cartridge
A CTO carbon block. Adsorbs chlorine and organics ahead of the membrane, which is what protects the membrane from them.
Rs. 750
10-inch Sediment Cartridge
The first mechanical stage. Traps sand, silt and rust before anything finer has to deal with them.
Rs. 550
GAC Carbon Cartridge
Granular activated carbon, working on chlorine and organics in the pre-filtration stack.
Rs. 750
Three Pre-Filter Set
Sediment, GAC and carbon block together — the routine replacement set for a domestic system.
Rs. 1,950
Post Carbon Cartridge
The polishing stage after the membrane, fitted where taste and odour are a consideration.
Rs. 1,100
Mineral Cartridge
Reintroduces selected minerals after the membrane, where that is part of the specification.
Rs. 1,100
UF Membrane
Ultrafiltration, used where the specification calls for it. It works on a different principle from reverse osmosis and is not a substitute for it.
Price on request
100 GPD RO Membrane
The separation stage itself. Price varies materially by brand and grade, so it is quoted from.
From Rs. 3,750
UV Lamp & Quartz Sleeve
Consumable parts of a UV stage, where one is fitted. The lamp and its sleeve are replaced periodically as part of servicing.
Rs. 2,200
Domestic RO Booster Pump
Supplies the pressure that drives water across the membrane. Without it the membrane does very little.
Rs. 6,500
4-Gallon RO Storage Tank
Holds treated water so supply meets demand at the moment of use rather than the moment of production.
Rs. 6,500
Standard 10-inch Filter Housing
The housing a 10-inch cartridge sits in.
Rs. 2,000
Domestic 10-inch UV Sterilizer
A UV stage for domestic systems, fitted where disinfection is specified for the application.
Rs. 7,900
The range
Selected products and treatment components. Other parts and capacities are available — ask for what you need.
Product prices are current website prices. Installation requirements and site-specific materials may affect the final total.
Stage 06
Everything before it exists to protect it, and everything after it polishes what it produces. This is the stage that changes what your TDS meter reads.
Feed water
Enters the housing under pressure from the booster pump.
Semi-permeable layer
Water molecules pass. Dissolved solids do not.
Product water
Spirals inward to the centre tube and leaves as treated water.
Concentrate
Carries the rejected solids away to drain.
A working membrane removes 90 to 99 percent of dissolved solids. It also produces a reject stream — an RO system uses more water than it makes, and anyone who tells you otherwise is selling something else.
Maintenance
The cheap parts protect the expensive one. Neglecting the cartridges is what kills a membrane early.
Service intervals depend on what your supply carries — a heavy sediment bore goes through pre-filters far faster than a clean mains connection. We set a schedule against your own water rather than printing one on a page.
Not sure which one
Tell us how many people are drinking it and what your supply reads. If you do not know the TDS, we will test it. Or call 0300-4334482.
