Outdoor air purifiers – what they are and how they can help the environment

Outdoor air purifiers – what they are and how they can help the environment.

With environmental issues being of increasing global concern, companies and governments around the world are looking at ways to reduce carbon emissions and reverse the negative impacts of pollution on our planet. Air pollution from vehicle emissions, agricultural activities and other industries are likely to blame for the increase in human respiratory illnesses – not to mention the devastating effects of rising global temperatures.

Pollution is a significant problem in many countries – particularly in urban environments. Industries such as transportation and aviation have a large role to play in helping to keep our air clean, so companies are increasingly looking for ways to cancel out emissions. One method that’s becoming increasingly popular is the installation of outdoor air purifiers.

These are inexpensive yet effective systems that can be placed in airports, covering large areas where pollution is likely to take place. They work by absorbing the layer of toxic atmosphere that is created by emissions, passing it through a built-in filtration system before releasing it back out again.

Solar powered Eco Mushroom – effective outdoor pollution control

A great candidate for airport spaces is the Eco Mushroom, a solar-powered outdoor air purifier system that is designed for placement in streetlights. This compact system is equipped with something called a CO2 Scrubber, which absorbs pollution. Shaped like a mushroom, the device captures warm, polluted air as it rises, sucking it up into an air purification system, which is situated in the middle of the mushroom.

Disposing of air pollutants

The system purifies the air and then releases it in a downward direction at a height of around two metres – the ideal height for human breathing. The Eco Mushroom is equipped with energy-efficient motors, which absorb the polluted air into the system. These motors are operated by batteries, which are charged by sunlight through a series of PV panels that sit on the top surface of the mushroom.

Effective monitoring

The performance of the Eco Mushroom can be monitored remotely, making it ideal for recording the levels of pollutants removed from the air and therefore the effectiveness of the device. Using GSM communication, the air filter sends signals to the monitoring station about performance and required maintenance.

Of course, there are many types of air filtration systems that can be used to reduce air pollution from aviation. Generally, those using high-efficiency particulate air (HEPA) filters are the ideal solution as they use the latest technology to cover larger areas of air more effectively. These systems are already being used by the likes of Boeing, built directly into its planes to capture more than 99.9 percent of airborne viruses and bacteria. These types of filters are popular for indoor use but are also capable of filtering outdoor air when built to a larger scale.
