The alert came two weeks before I would've noticed anything. Changed the filter on my own schedule, not a guess.

Your water.
Finally intelligent.
NeerSense clips onto the RO purifier you already own and reads every drop that passes through it — so you know your water is safe, and your filter tells you when it isn't, before it happens.

The device
One clip-on sensor. Two points of truth.
NeerSense sits inline with your purifier's plumbing, reading the water before your RO touches it and again after — the only way to know what your filter is actually removing.
Inlet sensor
Reads incoming tap or tank water before it enters your purifier — TDS, temperature and flow.

Every glass, tracked as it's poured — not estimated after the fact.
Predictive AI
Machine learning trained on real usage tells you what's coming, not just what's now.
Save money
Replace filters only when they're actually spent — not on a calendar guess.
Protect your family
Know instantly if quality drifts, before anyone takes a sip.
Smart alerts
A nudge on your phone, timed to matter — never noise.
Cloud analytics
Your data, secured and synced, accessible from anywhere.
Historical reports
Months of readings, turned into trends you can actually read.

Fifteen minutes, no plumber, no cutting into your purifier.
How it works
One line of water. One line of data.
The same path your water takes through your purifier is the path your data takes to your phone.
01
Your RO purifier
Water enters exactly as it does today — nothing about your purifier changes.
02
NeerSense reads it
Inlet and outlet sensors measure quality on both sides, continuously.
03
WiFi upload
Readings sync securely over your home network — no hub required.
04
Cloud + AI
Our models compare your data against usage patterns and filter behaviour.
05
Prediction engine
Remaining filter life is calculated from what's actually happening — not a fixed date.
06
Your phone
Everything above lands quietly in the NeerSense app.
07
Smart alert
You hear from us only when something is worth knowing.
The difference
Guessing vs. knowing.
Traditional RO
- Filter changed on a fixed calendar date
- No visibility into water quality
- Problems discovered by taste
- No usage or history data
- Servicing is reactive
With NeerSense
- Filter changed exactly when it's needed
- Live TDS and quality, always visible
- Problems flagged before you taste anything
- Full history, synced and searchable
- Servicing is predictive
Early feedback
What testers are noticing first.
★★★★★
Installed it myself in under twenty minutes. The app is the first water app that's actually pleasant to open.

With two kids at home, knowing the water is fine — actually knowing, not hoping — is worth far more than ₹49.

Questions
Before you reserve.
Yes. NeerSense installs inline with your purifier's existing plumbing — it doesn't replace or modify your RO in any way. It's compatible with Kent, Aquaguard, Livpure, Pureit, Blue Star, AO Smith and nearly every other purifier sold in India.
Completely. Your ₹49 simply reserves your Early Supporter slot and locks in the launch price. You can request a full refund anytime before your device ships, no questions asked.
NeerSense continuously compares incoming and outgoing water quality against your household's actual usage and environmental conditions. That's a far more accurate signal than a fixed replacement date, which is why most filters are changed too early or too late.
Around fifteen minutes, with the tools already in your kitchen drawer. No plumber, no cutting into your purifier, and the in-app guide walks you through every step.
A 2.4GHz home WiFi connection and a power outlet near your purifier. No hub or separate gateway required — it connects directly to your existing network.
Early Supporters get priority shipping as soon as the first production batch is ready. Reserving now secures your place in that first batch, in the order slots were reserved.
