Clean air used to mean buying an expensive machine, plugging it in, and hoping for the best. Aerosol scientist from IIT Bombay and clean-tech entrepreneur Ravi Kaushik decided that wasn’t good enough.
After eight years studying air pollution and its devastating impact on human health, Kaushik arrived at a deceptively simple truth: the most powerful fans in any building are already installed inside your air conditioner. The problem? They’ve been circulating poison.
That insight became AIRTH, India’s first AC Air Purifier company, and one of the most disruptive clean-tech startups in the country today.
The Dirty Secret Inside Your AC
Most people assume their AC is keeping the air clean. It isn’t. Standard AC mesh filters are engineered to capture large particles, not your lungs. Research confirms that indoor air can be significantly more polluted than outdoor air, and conventional ACs do nothing but recirculate it. Every breath in an AC room could be a recycled one.
“Some technology has to succeed — otherwise future generations will pay the price for the air we fail to clean,” says Ravi Kaushik, CEO of AIRTH.
The Smartest Fix No One Thought of First
AIRTH’s breakthrough is elegant in its logic: if an air purifier is simply a fan plus a filter, and your AC fan is already up to 5-10 times more powerful than any standalone purifier — why not use it?
AIRTH engineered FILTRIX technology, an AC-compatible antimicrobial HEPA filtration technology validated by IIT Bombay, IIT Delhi and IIT Kanpur. Also,tested from NABL-accredited labs, and BEE-certified labs. Installed directly into existing AC units, it transforms ordinary air conditioners into certified, high-performance air purification systems, with zero added electricity, zero bulky machines, and costs up to 75% lower than standalone air purifiers.
No new hardware. No extra electricity bill. Just cleaner air, at scale.

AIRTH doesn’t offer a one-size-fits-all solution. It offers the right one:
Summer Version maintains optimal airflow while purifying air during warmer, use when AQI is below 200 or in moderate air quality conditions
Winter Version maximises filtration during India’s most extreme pollution season, when AQI is more than 200
Trusted by 75,000 Families Pan India
Since launch, AIRTH has been trusted by over 75,000 families across India and is now deployed across homes,luxury societies, corporate offices, gyms, hospitals, hotels,schools, international organisations, and big real estate groups.
