Pure Skies 9000 for Events


Air quality at sporting events and festivals is of increasing concern for athletes, entertainers, fans, and sponsors alike.

Pure Skies 9000 can help.

Poor Air Quality for Athletes - Everyone Loses

From wildfires in California to vehicle emissions in Jakarta or crop burning in Delhi, concern over air quality at major events is becoming the new norm for deciding schedules for international to school-level sporting events.

Concern for air pollution at athletic events has forced multiple professional sports organizations, including the National Football League and the Board for Control of Cricket in India, to reschedule or postpone events due to poor air quality.

Outdoor air pollution is a major menace, especially affecting athletes and sportspersons who breathe heavily while performing.

During an event, sporting venues often have high levels of:

  • Particulate matter (PM2.5 and PM10)

  • Sulphur dioxide (which causes bronchoconstriction and asthma)

  • Carbon monoxide (which binds hemoglobin in the blood and reduces maximal performance, endurance, and attention)


So why is pollution so high during a game?


The influx of tens of thousands of cars, buses, and trucks at athletic venues, all arriving during a relatively short span of time, intensifies air pollution quickly. This adds to the regional influences affecting air quality that are already in play at the venue. 


Athletes are vulnerable to air pollution

Even though they enjoy elite levels of fitness, athletes are at special risk from air pollution. 

  • Physical activity increases minute ventilation (the amount of air taken into the lungs each minute). As a result, the number of pollutants that are inhaled relative to when the athlete is at rest are increased.

  • During activity, a larger proportion of air is inhaled through the mouth, which bypasses the body’s built-in nasal filtration system.

  • Pollutants are inhaled more deeply and may diffuse into the bloodstream more quickly during physical activity.

In athletes, low levels of pollution cause the same amount of lung damage as high levels of pollutants in non-athletes. Over the long term, this leads to asthma or chronic obstructive pulmonary disease. These risks are heightened in athletes with pre-existing lung or heart conditions.

Outdoor air pollution is a major menace, especially affecting athletes and sportspersons who breathe heavily while performing.


Several athletic associations have developed guidelines for training and competition activities based on air quality. For example, the National College Athletic Association recommends:

  • At AQIs of over 150, outdoor activities should be shortened, and exertion should be minimized by decreasing the intensity of activity. Sensitive athletes should be moved indoors.


  • At AQIs of 200 or above, serious consideration should be given to rescheduling the activity or moving it indoors. Prolonged exposure and heavy exertion should be avoided. Avoid all outdoor physical activity for sensitive individuals.


When major events are scheduled months in advance, however, moving or rescheduling an event can be logistically difficult. Wildfires in California, for example, have caused officials to consider moving or postponing several National Football League games over the last few years.


Dance. Freedom. Groove. Experimentation. These are part of the modern-day festival experience. But there are other “highs” at such events. 

Air quality at busy festivals tend to be poor. Smoke from tobacco (and other intoxicants we can’t mention here), dust from dirt roads, and vehicle emissions add to the mix.

PM10 and PM2.5 are kicked up from dusty outdoor dance floors by armies of 20-somethings hopping up and down at the same time.

At mass events such as a concerts, air pollution almost always intensifies and also affects a larger number of people.

​On the other end of the spectrum, religious and other festivals can draw hundreds of thousands or even millions of devotees, presenting significant environmental challenges including air quality. Re-suspended road dust, vehicle emissions, and smoke from choolahs used for cooking, cigars, hookas, and bidi cigarettes combined to send more than 15,000 people to local hospitals and medical camps during the last Maha Kumbh Mela.

Air pollution can also reach dangerously high levels during certain festival celebrations.

Pure Skies is perfect for Special Events


Sporting events, festivals, conclaves, ceremonies: Pure Skies can be quickly deployed and implemented to improve air quality when needed. 

Our "Clean Air as a Service" (CaaS) option makes it easy to deploy Pure Skies for limited events using a subscription or lease model. For venues with recurring events, either the subscription model or purchase of Pure Skies can be used. 

Devic Earth takes care of installation, maintenance headaches, and reporting. All we require are the appropriate permissions, and a place to keep our units (2'x2' space at a height, pole mounting for parking areas, or portable masts), and a power connection (30 W power consumption).

​We guarantee system uptime (>90%) and minimum improvement in air quality index (33%). 

Pure Skies 9000 reduces particulate pollutants (PM2.5 and PM10), nitrogen oxides, sulphur dioxide, and carbon monoxide. Overall air quality index improves by a minimum 33%.


Atmospheric carbon dioxide, the principal greenhouse gas responsible for climate change, reduces by 15-20 ppm. That's only a 5% decline, but better than anything else available today.

Importantly, Pure Skies does not adversely affect human health.
