Iron removal filter

Iron is the stain you can see and the taste you can’t ignore — and it has to come out before anything else does.

The problem this solves

What changes when the water is right.

01

Dissolved iron looks clear at the tap, then turns water yellow or orange the moment it meets air — staining basins, tiles, and white laundry.

02

Iron fouls softening resin and clogs RO membranes. Left untreated upstream, it shortens the life of everything after it.

03

Borewell-fed homes carry iron more often than the municipal record suggests. Treat it first, or rebuild the softener inside a year.

04

An iron filter is a media bed, not a cartridge. Sized to the iron load and backwashed on cycle, it runs for years.

How we solve it

Sized to the water, the house, and the people in it.

Chemistry

decides the media.

Household

decides the capacity.

Architecture

decides where it goes.

Engineered, not bought off a shelf.

What’s included

Everything to put it in. Everything to keep it running.

Media vessel

FRP / SS316 vessel sized to duty cycle. Media chosen at survey.

Backwash valve + drain

Manual or automatic backwash. Drain sized so regeneration never backs up.

Installation

Plumbing, electrical, mounting, commissioning. Documented before handover.

Water analysis

Pre + post-install parameter readings. Repeated on every visit.

One-year warranty

All system components covered. Replacement, not repair-by-letter.

One-year AMC

Monthly visit. Media check, backwash verify, downstream parameter test.

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.

Bathroom filter installed in the false ceiling

Inlet

Treats every tap from a single point.

Bathroom filter inside a wall cabinet

Pre-softener

Sits ahead of softening resin to prevent fouling.

Bathroom filter floor-mounted in a finished bathroom corner

Pre-RO

Sits ahead of RO membranes to prevent rapid clogging.

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.

Single-point

Bathroom or single line

One iron-removal vessel at the bathroom feed or a single line. Manual backwash.

Most chosen

Whole-house

2,000 — 4,000 LPH

Iron pre-treatment ahead of the HomeSoft train, so iron never reaches the softening resin. Automatic backwash on larger loads.

Heavy iron

Iron above 3 ppm

Oxidation plus media for high-iron borewells. Sized at survey to the measured load.

Frequently asked

What homeowners ask before they book.

Why does my water turn yellow / orange after standing?
That is dissolved iron oxidising. Water from a borewell can look clear at the tap, but once it sits and meets air the iron turns to rust and the water goes yellow or orange — the same stain you see on basins, tiles, and white laundry, often with a metallic taste. It is a treatable water-chemistry issue, removed by an iron filter sized to the iron load.
Does a water softener remove iron?
No. A softener targets hardness — it swaps calcium and magnesium for sodium on an ion-exchange resin. Iron is a different problem: dissolved iron fouls and coats softening resin, so it has to be taken out upstream by a dedicated iron-removal filter. On borewell-fed supply the correct sequence is iron pre-treatment first, softening second.
Iron remover vs water softener — which do I need?
It depends on what your water actually carries, which is why we test before we size. Iron staining (yellow/orange marks, metallic taste) calls for an iron-removal filter. Scale on geysers, fittings, and glassware calls for a softener. Borewell-fed homes usually need both, in that order — iron filter first to protect the softener resin. The free survey test tells you which.
How often does the system need servicing?
Year one of AMC is included with every install. Comprehensive tier is a monthly engineer visit; Standard tier is quarterly. Each visit covers parameter testing (hardness, iron, TDS, pH), backwash and regeneration checks, salt top-up where applicable, and a same-day written report. Iron filters and softeners are media-based, so periodic backwash verification is what keeps them performing.
Do I need to know my TDS or hardness before booking a survey?
No. The survey includes a free water test on the spot. The engineer takes the reading and walks you through what it means before any quote.
How long does installation take?
A bathroom install completes in a single day. A whole-house install typically takes one to two days, with most of the time spent on plumbing rather than equipment.
What if my supply chemistry changes over the years?
Monthly service includes parameter testing. If the chemistry drifts — borewells often do over years — we recalibrate media, regeneration cycles, and dosing.
Can I see what the system would cost before the survey?
We publish "starting from" ranges on the relevant pages. Final price is set after the free survey, based on your specific water and home.
Is the AMC included? What does it cover?
Year one of AMC is included with every install. Standard tier is quarterly, Comprehensive is monthly. Both include parameter testing, media inspection, and a same-day written report.

In your city

Iron in Kolkata water — the long read.

Why borewell-fed neighbourhoods east of the EM Bypass see iron, where it concentrates by locality, and the order treatment has to go in to actually work.
