7 ways to improve indoor air quality at work
Indoor air quality is a critical, yet often overlooked part of creating a safe, healthy working environment. Poor air quality can lead to a variety of health problems, including respiratory issues and allergies, as well as fatigue and decreased mental acuity.
Improving air quality at work requires a holistic approach combining technology, regular maintenance, and thoughtful office design. Controls that can significantly enhance workplace air quality include:
- Ventilation Systems: Modern Heating, Ventilation and Air Conditioning (HVAC) systems are designed to bring in fresh air from outside and filter out pollutants, dust, and airborne pathogens. Upgrading to a system that includes High Efficiency Particulate Air (HEPA) filters can capture at least 99.97% of particulate matter, ensuring cleaner air circulates throughout the workplace.
- Air Purifiers: In areas where ventilation may not be sufficient (or to create even cleaner air for vulnerable workers), portable air purifiers with HEPA filters are a great option. They're effective in removing dust, pollen, mould spores, and other particulates, further improving the quality and purity of the indoor air.
- Regular Cleaning and Equipment Maintenance: Dust and mould build-up can significantly affect air quality. Regular cleaning of ducts, vents, and filters, in accordance with manufacturer's recommendations, is essential in ensuring HVAC systems operate efficiently and effectively. Wet wiping of surfaces and regular vacuuming also assists to reduce dust and dirt that maybe brought into the workspace via high traffic areas.
- Control of Indoor Pollutants: The use of low-emitting materials for office furniture, flooring, and paint can significantly reduce the amount of volatile organic compounds (VOC’s) in the air. Consider implementing a procurement policy to ensure substances such as VOC's are minimised in the workplace.
- Use of Biophilic Design: Incorporating live plants within office spaces can naturally improve air quality. Plants can absorb toxins and produce oxygen, enhancing the overall air quality and office ambience.
- Optimising Humidity: Excessive humidity can lead to mould growth, while too little moisture can increase the risk of virus spread and respiratory irritation. Maintaining indoor humidity levels between 30% and 50% can assist to control these issues.
- Smart Building Sensors: Implementing smart sensors that monitor air quality, humidity, and temperature allows for real-time adjustments. This technology can ensure that the working environment remains within optimal parameters for employee health.
If you're concerned about workplace air quality, or are unsure about the best controls to implement, then consult with an occupational hygienist for further advice.
By promoting optimal air quality at your workplace, you not only address an often overlooked health and safety risk, but also create an environment that facilitates the productivity and ongoing wellbeing of your entire team.
