Indoor air is a lot worse than outdoor air. Many health symptoms experienced by workers are caused by indoor air pollution, which is why you should keep the air inside your commercial building clean and safe, promoting comfort among your employees but also protect their health. Poor indoor air quality can lead to productivity problems and increased absences among employees. Because indoor air pollution cannot be seen, it is easy to dismiss the fact that it exists. Pollutants such as cigarette smoke, dust, mold, mildew, and chemicals can exist inside the workplace. Approaches to detect possible indoor air quality normally include inspection, ruling out triggers, and testing. Inspection of the ventilation system to see if a sufficient amount of outdoor air is taken in and properly distributed throughout the area and if the filtration systems are working. Ruling out possible triggers of symptoms such as thermal comfort, noise, ergonomics, and poor lighting. Testing for the presence of air pollutants. This can be done using air testing kits. Samples are then submitted to the lab for analysis. You can improve your air quality by keeping your workplace clean and using eco friendly cleaning products that do not release harsh chemical compounds into the air. Having commercial grade equipment in your disposition, such as air scrubbers, dehumidifiers, and air purifiers are a great way to keep your indoor air quality at good levels and prevent the need to hire a professional. Properly ventilating and opening windows whenever possible while turning off your HVAC system will help the air quality as well. Changing your HVAC filters regularly will prevent dust and other air pollutants from circulating back to your indoor air. Taking these measures will decrease the amount of pollutants in your air and increase overall air quality.
