Children
Small lungs, still growing.
Children breathe faster than adults and take in more air for their size. Their lungs keep developing into their teens.
Whole-home air purifier. Fresh air in every room.
Fresh, H13 HEPA-filtered air throughout your home. Installed and maintained by aqi0 in Gurugram and Delhi NCR.
all taxes included
Why the air at home matters.
Each of us breathes about 11,000 litres of air a day — most of it at home.
Elders
Most at risk, too.
Older parents — especially with heart or lung conditions — are among the most affected.
Tolerance
You don’t get used to it.
Feeling used to the air isn’t the same as being protected from it. There’s no training dose: with pollution, less is better. Period.
Recovery
Home is where you recover.
Most of your hours — and your nights — are at home. Clean air there is a daily break from pollution: a place to breathe and recover.
Try it · one night, one bedroom
Drag through the night.
Two adults asleep, 10 pm to 6 am. On the left, the bedroom door shut and a single-room recirculating air purifier in the corner. On the right, the same room with aqi0.
CO₂ in the room
In the 1,200–2,500 ppm band
No fresh air coming in.
By morning, the CO₂ has nowhere to go.
Fresh-air supply
On, all night
Outdoor air, filtered on the way in.
Fresh air still flowing at 6:00 am. The air kept changing all night.
1,200–2,500ppm of CO₂
A closed bedroom with two adults and no fresh-air supply climbs to 1,200–2,500 ppm of CO₂ by morning. A recirculating purifier cleans the air already in the room. It can’t bring fresh air in, so it can’t bring CO₂ down. Why a closed bedroom climbs ›
One aqi0 air purifier for the whole home.
Installed in homes across Delhi NCR. One system covers up to 2,000 sq ft carpet, which is a 2, 3 or 4 BHK. For a bigger home, or one across floors, we specify two. We’ll confirm layout and sizing with you. See how it works ›

aqi0
Every room in the home.
Filtered outdoor air flows into every room, and stale air flows out.
How it works
One quiet system for the whole home.
It runs 24×7. Here is what it does to the air on the way in.
- Outdoor air in
- Fresh, filtered air
- Stale air out
- 1Draw & filter
Outdoor air comes in through H13 HEPA.
It passes a washable pre-filter first, then three H13 HEPA panels, one behind the other.
- 2Pressurise
Your home is gently pressurised.
Filtered air keeps flowing in, so stale air and CO₂ are pushed out through natural gaps.
- 3Every room
Every room gets clean air.
Day and night, the air keeps changing, and inside the home you live as usual.
Always ask what's inside. We'll tell you ours.
A fresh air unit is a fan, its filters and a box. Everything you pay for is in those three things, so here they are.
Filters
Three H13 HEPA panels, in series
Three filters, one behind the other, each H13 on Japanese media. H13 stops at least 99.95% of particles at the hardest size to catch. At each service we replace one panel, in rotation, so no single filter gets overloaded.
Fan
EC fan
Electronically commutated, backward-curved, variable speed. It draws about 30 W, which is about ₹173 per 30 days at 24×7 and ₹8/kWh.
Pre-filter
Washable, in front of all three
Takes the dust and lint so the expensive filters do not. Rinse it every 7–10 days. It’s a two-minute job.
Body
High-grade sheet metal
Mounted outdoors, on a wall bracket or a floor stand. Before we fit it, we check how much sun and rain the spot gets and whether it needs a weather cover.
Engineering
Made in India
Designed, assembled and tested in Gurugram. We build it and sell it direct. Read the technical note ›

Before

AQI 10–15
Indoor readings taken at installs across Delhi NCR.
The fine print
Readings like these need windows and doors to the outside kept closed, filters changed on time, no more than 2,000 sq ft carpet per system, and the kitchen exhaust running while you cook. All the conditions are in the technical note ›
The live reading below is outdoor PM2.5, right now.
The machine on your wall is the first of four parts.
Every aqi0 Home already installed is ready for the rest.

Room
aqi0 Room In development
An indoor companion for the one room that needs more than the whole-home system gives it. It isn’t a standalone purifier. It works only as an add-on to the system you already own.
