Sediment filter
The chained pre-treatment. Protects every system downstream. The cheapest filter, doing the most invisible work.
From ₹14,000. Final price after free survey. EMI from ₹1,167/month via Bajaj Finserv / Snapmint.
The problem this solves
What changes when the water is right.
Sand, silt, particulate from upstream pipes scratches valves and tears membranes.
Visible particles in water are usually a sign that something is wrong further upstream too.
A sediment filter buys downstream systems years of life. Without it, RO membranes fail in months.
Borewell water and old municipal lines both deliver particulate. Worst in monsoon.
How we solve it
Sized to the water, the house, and the people in it.
Every Uniwater sediment filter starts with a free water test and a site survey. The chemistry decides the media. The household decides the capacity. The architecture decides where it goes.
Catalogue sizes are starting points, not the sale. Our 17-rule auto-suggest engine generates a bill of materials specific to your water analysis, pressure, and draw — not a generic SKU pulled off a shelf.
Engineered, not bought off a shelf.
Inside the vessel
The engineering, in section.
What the system looks like on the cutaway. Media bed, distributor, freeboard, control head — the visible engineering that decides what the water does over the next fifteen years.
What’s included
Everything to put it in. Everything to keep it running.
Engineered vessel + media
FRP or SS316 vessel, sized to your draw and chemistry. Media chosen for the specific problem.
Controls & valves
Manual or automatic regeneration. Pressure gauges and flow meters where they matter.
Installation
Plumbing, electrical, mounting, and commissioning. Documented before handover.
Water analysis
Pre-install and post-install parameter readings. Filed with your quote.
One-year warranty
All system components covered. Replacement, not repair-by-letter.
One-year AMC included
Monthly preventive service on Comprehensive / Premium tiers. Standard tier gets quarterly.
Where it goes
Upstream of everything else.
Iron, sediment, and chlorine are pretreatment stages. They protect downstream resin, membranes, and softening media — or those systems fail faster.
Inlet
Treats every tap from a single point.
Pre-softener
Sits ahead of softening resin to prevent fouling.
Pre-RO
Sits ahead of RO membranes to prevent rapid clogging.
Architectural patterns
How the system fits, on paper.
Section drawings of the install patterns we use most often for this system. Pre-tile, mid-construction, or as a retrofit — the right pattern is decided at survey, against the house.
02 · Utility room
Indoor controlled environment. Easiest service access, full 4-stage train fits.
03 · Terrace
Rooftop install with weather hood. Uses existing OHT gravity-feed, exposed to elements.
04 · Basement
Villa basement plant room. Centralised, sump pit handles backwash, full 4-stage train fits.
Configurations
Three or four sizes. Decided by load, not by SKU.
We don’t expose part numbers. The configuration is decided at survey based on bathroom count, household draw, and water chemistry.
Bathroom Mono / Duo / Trio
Per-bathroom
Pre-treatment for a single feed.
Whole-house 2K / 4K / 6K LPH
Inlet
First stage of the HomeSoft four-stage train.
