The Problem

You bought a room purifier.
It's not enough. Here's why.

Stale air in a loop

Room purifiers recirculate the same indoor air — they never bring fresh air in. Windows shut = CO₂ builds. You're cleaning the same stale air, over and over.

One room, not your home

At peak pollution, coverage drops to 100–200 sq ft. A 3BHK needs 6–8 units. One for every room. Every night.

Filters choke silently

No alert. No data. By the time you notice the smell or the readings, you've been breathing dirty air for weeks.

How It Works

The Positive Pressure Principle

Fresh outside air. Precision-filtered through 4 stages. Pushed into every room. Stale air out.

Outside air enters

Fresh outdoor air is drawn in through a 200mm intake — never recirculated indoor air. Every breath your family takes is filtered outdoor air.

4-stage filtration

Pre-filter → Medium filter → HEPA H14 → Superior allergen filter. 99.997% particle capture down to 0.3 µm — the size that reaches your lungs.

Clean air fills every room

Purified air is pushed in under gentle positive pressure. It travels through corridors and door gaps — every room, simultaneously. No ducting. No false ceilings.

Polluted air is expelled

As clean air builds, stale and polluted air is pushed out through micro-gaps and exhaust vents. Your home breathes.

Why airTENO

One system.
Every room. Zero compromise.

One system, not six

A 3BHK needs 6–8 room purifiers — one per room, every night, every room you care about. airTENO MAX is a single unit covering your entire home simultaneously. One switch on. Done.

Smart monitoring, zero hassle

We watch your AQI data 24/7, alert you before problems happen, and schedule filter changes based on real data — not a calendar. You check in when you want to. We handle the rest.

Fresh air — not recycled

Room purifiers clean the same stale indoor air on a loop. airTENO draws fresh outdoor air, filters it through HEPA H14, and pushes it through every room. CO₂ stays balanced. Your family breathes genuinely fresh air.

Designed to disappear

The unit mounts on your balcony or utility wall — outside your living space. No machine in the bedroom. No tower in the corner. Your home looks exactly as you designed it.

What Homeowners Say

Delhi NCR families,
in their own words.

Though I've been using air purifiers — I found this much better. One switch, one unit for the whole house. Brought AQI down more than any room purifier.

Homeowner, GK1, New Delhi

My big Dyson wasn't enough — I felt choked. This works. The AQI is much lower. I've decided to get it for my other home as well.

Common Questions

Everything you want to know

Room purifiers clean one room and recirculate stale indoor air. They don't bring fresh air in. CO₂ builds up when windows are shut. airTENO draws fresh outdoor air, filters it to HEPA H14, and pushes it through every room simultaneously. Ask yourself: what's the AQI in your bedroom at 2am? We can show you.

HVAC purification requires ducting that permanently lowers your ceiling by 8–12 inches — major civil work, ₹3–8L, specialist maintenance. airTENO is a half-day install, no false ceilings, subscription-based. The systems are not comparable in cost, disruption, or reversibility.

100-day money-back guarantee. We install AQI sensors on day one — if the numbers don't improve, the data would show it and we'd refund you. We've never had a customer with functioning sensors ask for a refund.

airTENO is a brand of Afferent Wearable Tech Pvt. Ltd. — in business since 2014, 20,000+ customers through our SandPuppy healthcare brand. We're not a startup selling purifiers out of a garage. Product design, manufacturing, and service are all in-house.

60 dB(A) — and the unit is mounted outside your home (balcony/utility area), not inside your living space. You won't hear it indoors at normal operating levels.

Depends on your air quality data — not a fixed calendar. In peak pollution (Oct–Jan Delhi NCR), typically 30 days. Moderate conditions, up to 60 days. We monitor your data and alert you proactively — you don't track it.

About airTENO

We live in Delhi.
We breathe what you breathe.

airTENO started because we couldn't find a whole-home clean air solution that actually worked — so we built one.

Delhi NCR crosses AQI 300 for 60+ days a year. We watched health-conscious families spend ₹50K–₹80K on room purifiers and still breathe polluted air at night. HVAC purification required false ceilings and ₹3–8L in civil work — viable only in high-end new construction. The gap was obvious. We built it.
