Over the past two years, the issue of ventilation in offices, factories, warehouses and other workplaces has become of paramount importance, and air cleaning units have been increasingly used to ensure that employees who are not or cannot work from home are as safe as possible.
By law, all workplaces need to be adequately ventilated and depending on the job in question this can either be through natural ventilation or mechanical devices that help swap hazardous air for fresher, healthier air.
This can be increasingly difficult in colder, wetter weather, especially during winter, where many natural ventilation solutions are uncomfortable at best and can cause a potential risk of illness at worst.
However, it is important to focus on ventilation as a priority, not only for the obvious health considerations during a time when public health is paramount, but can also affect productivity and create an unpleasant working environment.
Poor ventilation leads to a build-up of carbon dioxide and lower levels of oxygen, which can at high levels cause fatigue and headaches in a condition known as hypercapnia.
Beyond this, poor ventilation and an increase in the use of strong cleaning chemicals to sanitise work environments can cause poor air quality, and a range of conditions from fatigue to nausea, shortness of breath and coughing.
This can in some cases lead to a condition known as sick building syndrome, where being in a certain workplace can lead to a range of unpleasant symptoms that get worse the longer you are in a building and quickly disappear once you leave.
