Why we started

We started Dr. Water because bad water affected us and our families at home. Dry, rough hair. Skin that felt tight after a bath. Brown marks in the bucket and white crust on the taps. Better water should be simple, so we're making a filter for the shower you already have, and we'll always be straight about what it can and can't do.

What's in your water

Four things that come out of the shower

Most of us never think about it. This is what usually comes out of the shower in Indian cities, and where it comes from.

  • Chlorine

    City water boards add it to keep water safe to drink. That part is good. In a hot shower, it can also strip the natural oils from your hair and skin.

    The filter is built to catch this

  • Rust and dirt

    Old pipes, rooftop tanks and tanker water add rust and dirt. You've seen it as brown marks at the bottom of the bucket.

    The filter is built to catch this

  • Metals such as iron

    Water picks up iron and other metals from pipes and from the ground. Borewell water often carries more. It's what leaves orange-brown stains on tiles.

    The filter is built to catch this

  • Hardness: calcium and magnesium

    These react with soap and shampoo and leave a film on hair and skin, and white crust on taps.

    The filter helps with the effects. It isn't a softener and doesn't remove hardness.

If your hair stays dry or your scalp stays itchy, see a dermatologist. Water can make dryness worse, but it's rarely the only cause.

Try it

Turn on the shower and watch

Two showers, the same tap water. Screw the filter onto the right one and see what reaches the bucket.

Start the water, then tap the filter to screw it on.

Calcium and magnesium pass through, because the filter isn't a softener. This is a simulation to show the idea, not a lab test.

How the filter works

15 stages between your pipes and your hair

  1. 1 · From your pipes

    Tap water goes in

    • Chlorine
    • Rust and dirt
    • Metals such as iron
    • Calcium and magnesium

  2. 2 · Inside the filter

    It passes through 15 stages

  3. 3 · Onto your hair and skin

    Passes through

    • Calcium and magnesium

What it doesn't do

It isn't a water softener. Calcium and magnesium pass through, so your TDS reading won't change much. The filter is built for the chlorine, rust, metals and dirt.

Check your water

Four ways to check your water at home

You don't need a lab. Most of these take a minute.

  1. Look at your taps

    White crust around the tap mouth or the shower holes is dried calcium and magnesium. It means your water is hard.

  2. Try the soap test

    Fill a clear bottle one-third with tap water, add a few drops of plain liquid soap and shake. Little foam and cloudy water means hard water.

  3. Read a TDS meter carefully

    A high number hints at hard water but doesn't prove it. TDS counts every dissolved solid, not only hardness.

  4. Tie a white cloth to the tap

    Leave it for a day. Brown marks on the cloth, or brown residue in your bucket, point to rust and sediment.

Questions

Questions people ask us

Will it fit my shower and tap?

It fits standard ½-inch (20 mm) shower arms and bathroom taps, which most Indian bathrooms have. Attachments for taps that need them come free in the box.

How long does one filter last?

About 6 months of daily use. We'll message you when it's time to replace it, so you don't have to keep track.

Will it lower my TDS or soften my water?

No, and we'd rather say so now. The filter isn't a softener. Calcium and magnesium pass through, so your TDS reading won't change much. It's built to catch the chlorine, rust, metals and dirt in your water, and it helps with the effects of hard water, like the film soap leaves behind.
