Wearable air purifier · In testing in Bengaluru
Clean air for every mile. No mask.
On the road there’s nothing between you and the air. ClearMile filters street air at the back of your neck and surrounds your face with a curtain of clean air — with nothing strapped over your nose and mouth.
The problem
There is no clean-air city in India. And on the road, you can’t shut the window.
Every one of India’s 1.4 billion people lives where fine-particle pollution (PM2.5) is above the World Health Organization’s guideline. At home you can close a window or run a purifier. On a two-wheeler, on foot, on a bicycle — at the signal, behind the bus, past the construction site — you breathe whatever the street gives you, often hard and for an hour or more a day.

India’s own PM2.5 standard (40 µg/m³) is eight times looser than the WHO guideline.

of life the average Indian would gain if the air met the WHO guideline.

the same gain for people living in Delhi.

What the air costs
Bengaluru’s air costs about two years of life. Delhi’s, more than eight.
Why masks haven’t fixed it
The only tool on offer is a mask. Almost nobody keeps one on.
A mask that stays in your pocket filters nothing. We asked why people take them off — and designed around every answer.
It’s hot
A damp layer of fabric over your mouth, in Indian weather, for your whole commute.
It fogs
Every breath goes up into your glasses or helmet visor — a real problem on a two-wheeler.
You can’t talk in it
Down it comes for a phone call or a chai stop, and it rarely goes back up.
It only works if it seals
Beards, helmets and the wrong size leave gaps, and air simply goes around the filter.
The solution
ClearMile: a curtain of clean air, not a mask.
Instead of strapping a filter over your face, ClearMile brings filtered air to it. The device sits at the back of your neck; nothing seals to your skin, so you can talk, smile and drink as normal.
Filter
A quiet fan at the back of your neck draws street air through a pleated filter before it reaches anything else.
Carry
Slim ducts along your jawline bring the filtered air round to the front of your face.
Curtain
An outer curtain of air pushes street air away, while a gentle inner stream gives you filtered air to breathe.
What it is
- Worn at the back of your neck — nothing on your face
- Free to talk, smile and drink while you wear it
- A replaceable pleated filter and a rechargeable battery
- Designed and built in Bengaluru, for Indian roads and weather
What it isn’t
- Not a mask — nothing seals to your skin
- Not a medical device, respirator or PPE
- Not a replacement for medical advice
Who it’s for
Everyone who spends the day in street air.
Two-wheeler riders
Daily commutes through traffic and signals.
Walkers
The walk to the metro, the bus stop, the office.
Cyclists
Breathing hard, right next to the traffic.
Runners
Early-morning miles when the air is at its heaviest.
