Air pollution control equipment for industrial zones
What we did:
A prominent industrial zone in Mumbai was subject to numerous complaints about air pollution from neighboring residential areas. In just 6 weeks, Pure Skies reduced average levels of particulate pollutants by 36-40%.
Industrial zones are engines of economic growth. Unfortunately, air pollution from operations in these areas can be problematic. Public nuisance complaints, fines from state pollution control boards, and even plant shutdowns for polluting industries can make life difficult for companies and neighboring residential areas alike.

One of Devic Earth’s partners, a large industrial zone in Mumbai, wanted to improve air quality throughout their entire property. They had received a number of complaints from neighboring colonies as well as punitive fines.
Despite taking several measures, air quality measured inside the campus inside remained poor. Particulate matter – PM2.5 and PM10 – were 224 and 260μg/m3, respectively, averaged over one week. This is much higher than what is recommended by the National Ambient Air Quality Standards (PM2.5 < 60 μg/m3 and PM10 < 100 μg/m3) and more than 10 times higher than standards of the World Health Organization..
Employees were exposed to high levels of harmful pollutants which would impact their health and productivity.
Two Pure Skies 9000 air pollution control systems were installed around the campus. The installation consisted of Pure Skies base stations, extender units, and third party air quality monitors (Environmental And Engineering Solutions Pvt. Ltd., Aligarh).
The system was configured to handle particulate pollutants (PM10 and PM2.5) and common pollutant gases (NOx, SOx) across approximately 150 acres.
Outdoor air pollutant levels were monitored continuously at appropriate locations around the industrial zone to help the customer understand the efficacy of Pure Skies, as well as to provide real time data for optimizing the smart technology in each Pure Skies unit.
Installation technical details:
It took just one and a half days to complete the installation. The base stations, extenders, and air quality monitors were installed on either building rooftops or utility poles. No floor space was required. Equipment was plugged in and connected wirelessly to the local GSM data network in the area.
Power requirements: Routine power supply (ordinary 10A sockets). Each base station and air quality monitor are equipped with battery backup.
Once online, the performance of each air pollution control unit is monitored by Devic Earth 24x7.
Pure Skies' built in smart technology allows each unit to understand air quality patterns at its location and optimize its output accordingly.
The property manager and EHS head were given secure logins to view the industrial zone’s air quality data on a convenient app.
After Pure Skies was powered On, air quality showed a steady improvement in a short period (Figure 1).
In just three weeks, Pure Skies reduced levels of PM2.5 and PM10 were reduced by 36% and 40%, respectively.
Plant output, number of workers, and local weather patterns remained stable during this period. There was no precipitation (rain).

The successive green bars depict the incremental decrease in the levels of the pollutants over 7-day intervals. Data source: 3rd party air quality monitor (Environmental and Engineering Services Pvt. Ltd., Aligarh), pre-calibrated against a reference grade monitor.
Pure Skies is a state-of-the-art air pollution control system that ensures that the employees working in the industrial zone as well as those living in neighboring communities breathe clean air.
What’s the value of cleaner air to you and your industrial zone?
Reduced sick days
Cleaner air means a stronger immune system. A study from several of Devic Earth’s customers showed sick days reduce by 11-13% year-on-year after installing Pure Skies!
Worker productivity drops by 1% for every increase in PM2.5 levels by 10 mcg/m3, according to researchers from Columbia University. For a typical factory with PM2.5 levels averaging 220-230 mcg/m3, that’s like watching productivity drop by 16-17%!
Improving air quality index (AQI) to less than 50 improves the productivity of employees by 5-6%, which in turn increases the profitability of the company by 1%, according to a study published in the Harvard Business Review. Also, a money saver when it comes to paying fines to the CPCB for bad air quality.
If that’s not good business sense, then we don’t know what is!
