The air you breathe is invisible.
Most people spend 90% of their lives indoors. The air in those rooms is 2 to 5 times more polluted than the air outside, and it is invisible, odourless, and accumulating right now.
20 years in the field.
One product for every building.
Ventara builds ventilation for the way the world constructs today. The people behind it spent 20 years inside the buildings that demand the most: hospitals, schools, factories, and high-specification builds across India. That experience is in every product.
The founders spent 20 years inside the buildings that demand the most. Critical care wards where 1 ppm of contamination is one too many. Classrooms where 40 children breathe the same air for 6 hours. Factory floors where ventilation is a regulation, not a comfort.
They saw a pattern Indian homes had never measured. The same problems, the same particles, the same CO₂ build-up, present in every sealed apartment and every glass-fronted office. The hardware that could solve it existed. The product an ordinary building could afford did not.
A quiet exposure,
every breath, every hour.
“We were running our ICU at 1,600 ppm and didn’t know it. After the retrofit, the night shift stopped complaining of headaches inside a week.”
3 categories,
one standard of air.
Energy-recovery and heat-recovery ventilators, ducted units, commercial systems. Every product engineered for Indian dust, monsoon humidity, and the way our grids actually behave.
ERV / HRV

Wall-mounted and ducted units for 1 to 6 BHK apartments and homes. 100 to 500 CMH.
Ducted &
concealed range
Offices, schools, hotels and retail. 500 to 20,000 CMH with BMS integration and demand control.
Filters &
accessories
HEPA H13 cartridges, CO₂ sensors, grilles and controllers. For every Ventara system.
Where clean air
changed the space.
Why fresh air matters
in a high-rep room.
A 60,000 sq ft gym in Delhi recorded peak CO₂ above 1,800 ppm. After Ventara ERV install, sustained 720 ppm at full class capacity.

learning instrument.
Across 14 Delhi NCR schools, classrooms hit 1,400+ ppm by mid-morning. Ventara dedicated-OA systems kept them below 800 through the school day.
Read case study →Infection control
starts with the air.
A 240-bed multi-specialty hospital in Gurugram saw HAI incidents fall 31% within 6 months of fresh-air retrofit. CO₂ from 1,650 to 690 ppm.

What is an ERV and how is it different from an air conditioner?
An Energy Recovery Ventilator (ERV) brings filtered fresh outdoor air in and pushes stale indoor air out, exchanging heat and humidity through a recovery core. An air conditioner only recirculates and cools the same indoor air. It does not remove CO₂, VOCs or bioaerosols. Cooling without ventilation concentrates those contaminants; an ERV removes them.
Do I need ventilation if my home is open-plan or has windows?
Yes. Open layouts move air sideways but do not exchange it, so CO₂ and off-gassing still accumulate. Opening windows in most Indian cities swaps indoor CO₂ for outdoor PM2.5 that is 6–10× the WHO safe range. Mechanical ventilation with HEPA filtration delivers fresh air without that trade-off.
What airflow (CMH) do I need for my space?
As a rule of thumb, target roughly 30 m³/hour of fresh air per person, adjusted for room volume and use. Ventara sizes every system to the actual square footage, occupancy and building type. Share your details on the contact form and we return a sized system, price band and timeline, usually within 24 hours.
Are Ventara systems built for Indian conditions?
Every product is spec’d for Indian dust load, monsoon humidity and voltage fluctuation, with G4 + F7 + HEPA H13 multi-stage filtration and EC motors that tolerate real-grid conditions, not lab conditions.
Do you install, or is it self-install?
Both. Residential ERVs are available for self-install through the online shop with engineer support, and we have 120+ authorised installers across 25+ cities for full sizing, install and service.
What warranty and service do you offer?
Ventara systems carry a 5-year warranty on the recovery core and 2 years on the motor, with nationwide service and a 5-year filter/accessory service plan.
