Indoor Air At Work

We spend a considerable part of our lives working in tightly sealed air-conditioned spaces, without giving much thought to the office air quality.

Since office windows are rarely opened, the office air quality is often not as fresh as it should be. Electronic devices such as computers, printers, copiers, and even the telephone on your desk harbour bacteria, dust and other common health triggers. Chemical sprays used to clean desk tops, windows and carpets worsen the situation. It is not uncommon for potential mould to infest the office storage and other damp spaces.

Poor office air quality should be of great concern for businesses because it has a direct affect on employee health. Poor indoor air quality can lead to sneezing, coughing, dizziness, fatigue, headaches, nasal congestion, skin allergies, sore throat, nausea and eye irritations.

How healthy is the air in your office?

Investing in the indoor office environment is not just about improving the well-being of employees and visitors to your office, it can significantly improve the bottom-line as well. A healthier workplace improves workforce comfort, increases employee productivity and reduces absenteeism. Healthier, happier employees deliver better results!

Reduce Exposure to Indoor Pollutants

As a business owner or manager of an office space, there is a lot you can do to reduce and remove sources of indoor pollutants and reduce adverse health effects. Here are a few suggestions:

  • Smoking should not be allowed both inside the office and within a metre of the entrance. The designated smoking area should be located a sufficient distance from office doors, windows and ventilation systems.
  • Place large door mats at the office entrance to reduce the amount of dust, pesticides, pet dander and other pollutants that are carried in stuck on people’s shoes.


Door Mats

Choosing the right door mat will help reduce the dust entering your house. To help you out, we have done some research and found these that will do the job.


  • If you are moving into a new office, you may want to avoid wall-to-wall carpeting. If you do have carpeted areas, use vacuum cleaners with HEPA filter and power head.
  • Where possible clean the dust in the office with a damp cloth or mop.
  • Air fresheners are popular in offices, but they add to the chemical air contaminants. STOP using air fresheners.
  • Use cleaning products with natural ingredients. Avoid products with chlorine, ammonia or bleach.
  • Check any seepage from plumbing pipes, toilets, dishwashers, walls and windows and dry immediately to prevent potential mould growth.
  • Indoor plants are a great way to splash some colour in the office space, and naturally cleanse the air, regulate humidity and moisture. NASA and Dr B.C. Wolverton discovered that house plants remove and or reduce air pollutant contaminants and in turn improve indoor air quality.


Hire an Indoor Plant for your Office

If your work space is particularly poorly lit or you’d like a particular plant in your office that needs more light than is available, we can work around this by regularly rotating plants from your work space to the nursery to ensure they remain healthy and lush. Check the options available here at The Garden Path.

  • Do not use pesticides inside the office, instead choose non-toxic pest control methods.
  • Use low VOC paint when renovating your office.
  • Ensure regular maintenance of the office heating, ventilating and air conditioning systems. According to WHO (2008) moisture-related heating, ventilation and air-conditioning components such as cooling coils and humidification systems, when poorly maintained, can be sources of microbiological contaminants that cause adverse health effects in occupants. Change air filters in these systems regularly. 
  • If possible, open office windows for natural ventilation.
  • Use furniture made from solid wood. Alternatively, apply water-based sealant to pressed wood furniture to prevent chemicals present in the pressed wood from polluting the indoor air.

If the problem persists even after you have identified and remedied obvious sources of indoor air pollutants, seek outside help such as local or state health departments or consultants in industrial hygiene and Building Biology.

What initiatives has your office taken to improve the indoor air quality?

As Building Biologists, we have acquired knowledge of adverse health effects and recommend effective strategies to reduce occupants’ exposure by eliminating and controlling as many sources of pollutants in order to create healthy indoor living environments that are as exposure-free and natural as practically possible.
