Clean Air – The Key to Healthy Employees and a Healthy Business

It’s a no-brainer in these times of Covid-19, a must-have for every company that cares about its workers. Plus, it’s great for the balance sheet too.

Clean air in the workplace not only stops workers inhaling harmful substances but can protect them from viruses too.

And considering we spend more than one third of a typical day at work, that’s not to be taken lightly.  

Polluted Air Causes Serious Health Problems

Working in polluted air is a major cause of many health problems and occupational diseases, such as asthma, COPD, and lung cancer.

“We’ve helped so many companies where poor air quality is causing employees to complain of headaches, lack of concentration or to regularly call in sick,” says Ben Simons, Head of Europe West at Zehnder Clean Air Solutions.

A healthy work environment is the basis for employee satisfaction and motivation.

“This is extremely worrying for a responsible employer – doubly so when they see productivity decreasing through absences, and costs rising too.”

Typical Sources of Poor Air Quality at Work

Harmful pollution particles come in all shapes and sizes. Many of the most dangerous are invisible to the naked eye. They include:

    • Chemical vapours released by paint, glues or cleaning agents
    • Substances released when materials are heated or burned, such as in welding
    • Mould in damp rooms
    • Exhaust fumes from nearby roads or forklift traffic that are blown into the workplace
    • Dust or fumes from grinding and cutting, such as silica and nickel dust.

Clean Air – A Good Return on Investment

Various studies have shown that healthy indoor air reduces sick leave and increases productivity[1]. Moreover, healthy employees are more satisfied and motivated[2]

In fact, The CBI calculates that 3 million working days currently lost to illness in the UK could be regained if air pollution was reduced to the WHO recommended levels. The increased productivity would gain the UK economy £1.6 billion as a result, and workers would benefit through an additional £900 million in earnings currently lost because of air pollution[3].

Industrial Air Cleaning in Practice

There are thousands of companies around the world that have discovered the benefits of clean air.

Take Bells Food, one of Scotland’s best-known bakeries. Their philosophy has always been to put their employees first – and to go the extra mile when it comes to their health.

After installing industrial air cleaners, Bells reduced harmful dust particles at their main Shotts factory by 68%.

“Studies have shown that indoor air quality can be so much worse than outdoors,” says Zehnder’s Ben Simons. “It doesn’t help that regulations governing indoor air are lagging well behind the rules for that outdoors. So, any responsible employer has to ask themselves: Am I doing enough about air quality in the workplace?’”
