An independent reference
What clean drinking water actually means, for you
What’s really in the water coming out of your tap, what counts as safe, and — once that part is clear — what actually treats it. No brand comparisons.
Every claim is checked against sources such as BIS, WHO, CGWB and FSSAI—not a purifier company’s marketing material.
The problem
Almost nobody knows what’s in the water they drink every day
Not through carelessness — the information is genuinely hard to find, and almost everyone explaining it is also selling something to fix it. So a TDS number gets quoted like a safety score, and the contamination that actually shapes health here — fluoride, arsenic, nitrate — barely gets mentioned, because no product neatly solves it.
Three things most people believe
“Low TDS means the water is safe.”
It says nothing about bacteria, fluoride, or arsenic.
What TDS actually measures“Boiling takes care of everything.”
It kills what's alive. It does nothing to what's dissolved.
What boiling does and doesn't do“RO is always the safer choice.”
On already-clean supply, it just strips minerals and wastes water.
When RO is actually the right call
The vision
An encyclopedia for water in India — every contaminant, every technology, every myth, answered properly, in one place.
No chemistry degree needed, no salesperson attached. Just a reference that keeps growing, and keeps correcting itself as the evidence does.
How this reference is organised
Understanding your water
What's actually dissolved or living in Indian water, region by region — and the standards used to judge whether it's safe.
- TDS levels explained: what's safe, what's too low
- Fluoride, arsenic, nitrate: what's actually in your water
- Municipal, borewell, or tanker: why your source matters
Treating your water
RO, UV, UF, softeners and gravity filters: what each technology actually does, what it costs, and how to keep it working.
- RO vs UV vs UF: which one your water actually needs
- Hard water, explained: what it is and whether you need a softener
- What a purifier really costs over 3 years
Myths & misconceptions
The claims purifier marketing repeats most often, checked directly against the evidence.
- Does RO water strip out minerals you need?
- Does boiling remove everything harmful from water?
- Is bottled water actually safer than purified tap water?
How each guide gets written
- 1
Researched
Drafted against primary sources — BIS, WHO, CGWB — not other blogs.
- 2
Independently checked
A separate pass flags any claim that's unsourced or overstated.
- 3
Revised, then published
Every flag gets fixed before it goes live — and stays dated.
Start with your own water: what’s in it, and whether it needs treating at all.
