Vistar – A Smart Air Purifier Developed by IIT Madras Startup AirOk

According to a recent report by the World Health Organisation (WHO), nearly 9 out of 10 people around the world breathe polluted air and an alarming 7 million people die each year from air pollution due to air pollution levels remain dangerously high in many parts of the world.  

Breathing polluted air can lead to heart disease, a stroke and lung cancer. More than 90% of pollution-related deaths occur in low- and middle-income countries, mainly in Asia and Africa.   

“Air pollution threatens us all, but the poorest and most marginalized people bear the brunt of the burden,” said Tedros Adhanom Ghebreyesus, director-general of the WHO.    In fact, an indoor air can be anywhere from two to five times as polluted as outdoor air and one needs to aware about this situation and attempt should be made for a cleaner and healthier air in the house.   

The indoor air quality in your home or workplace can have a big effect on your health, productivity, and overall comfort. Cool air doesn’t mean clean air! It’s true that cool air comforts but clean air makes feel lively throughout the day.   

Pollutants, mold, poor ventilation, exposure to chemicals and a number of other factors can contribute to poor indoor air quality in an office environment. Do you think you need clean air at your workplace? Most of us spend a large amount of time at our workplaces. So clean air in the workplace can improve our efficiency and keeps the energy flowing.  

A number of health conditions may arise from long-term exposure to poor air quality including – Allergy symptoms include coughing, sneezing and runny nose, fatigue, sore throat, dizziness or a headache.  

To tackle the issue of indoor air pollution, a team of IIT Madras start-up AirOK Technologies, namely Vijaya Savanth, Pavan Reddy, Deekshith Vara Prasad, Sravan Krishna and Bhanu Prasanna Varma has built an India’s first indigenously made smart air purifier called ‘Vistar’.  

After 3 years of R&D with an innovational approach to attain clean air with conventional designs they came up with VISTAR450 a uni filter Air purifier with dual stratified filter technology.  

It includes futuristic features from Wi-Fi to touch interface to remote monitoring via mobile phone. The product will be marketed to residential segment by Delhi-based SAR group.  

AirOK functions as a catalyst- progressing energy innovation and technology transforming India’s economy and helping people to choose clean and efficient energy as part of their lives.  

The air purifier Vistar has many special features such as customized services, real-time monitoring, cost-effective, timely services and reliable. It comes with an affordable price at ₹20,000 and has useful life about one year, which is twice that of the air purifier currently available in the market.   

Built on a cylindrical model, the metallic silver coated air purifier comes in two models, Vistar 450 and Vistar 550, with 300mm diameter and 520 mm in height, weighing 8 and 9.5 kg, respectively. “We are planning to make this as a ₹100-crore brand in the next five years,” said Deekshith Vara Prasad, Founder, and CEO, AirOK.  

Powered by Efficient Granular Adsorbent Particulate Arrester (EGAPA) technology, the patented filter technology from AirOK, the purifier will filter a variety of pollutants such as Particulate Matter (PM), microbes, fungus and gaseous substances.  

The technology used in the Vistar can estimate the percentage of pollutants in the air at any given point. With a dual stratified filter technology, it has the capability of filtering particulates up to 0.3 microns. These particulates include volatile organic compounds, acidic and basic pollutants, to airborne bacteria and pet dander.   

“Vistar 550 has a coverage area of 550 sq ft with a filter life of one year, which is twice that of the air purifiers currently available in the market,” said Ashok Jhunjhunwala, faculty-in-charge, IIT Madras Research Park, while launching the product as reported by the Business Times.  

The purifier is designed by modeling the dispersion of indoor air pollutants considering the air flow dynamics and energy efficiency the air intake and exhaust slits were designed at a 45-degree inclination to achieve airflow pattern with maximum efficiency, according to the start-up.  

The AirOk Home app monitors the filter lifespan and sends notification reminders to your smartphone when your filter needs replacement and it also monitors your workspace air quality in real time from anywhere when you sync with AirOk App.  

Since monitoring is a precursor for control strategies AirOK is dedicated to deploying a network of air quality sensors which can generate powerful insights about what actually people are breathing in different environments.  

Designed for the institutional segment, AirOK targets hospitality, real estate, food processing and manufacturing sectors as its primary market for the product.  

The smart air purifier can be placed in any corner of the room where it can sense the pollution level and automate the fan speed, based on the concentrations of the pollutants. Incubated at the IIIT Madras, Vistar can not only work in homes but also in hospitals, commercial real estate and food processing.  

Good device to filter indoor air pollution, while delivering this device to the consumer company also give indoor plants (aloe vera, spider plants, etc.) along with this device, to make realize people that natural air purifier is the plants.  

This made in India product is wonderful and needs to be encouraged due to its clear advantages and performance over the existing air purifiers.
