Odours in enclosed, air-conditioned offices: implications for staff comfort and productivity

If a sealed office has poor ventilation, carpets and air conditioning systems easily breed mold and accumulate odors, affecting employee health and efficiency. This article provides a five-step battle plan to improve air quality.

Office odors stem from central air-conditioning mold and carpet dust accumulation. It is necessary to periodically clean air-conditioning filters, perform deep carpet steam cleaning, and ensure the fresh air system operates normally. If odors persist, you should commission a professional team to perform air purification.

Causes of odors in closed spaces

Commercial buildings keep central air-conditioning running for long periods with windows closed, creating an air concentration effect. Unwashed filters and carpets adsorbing coffee stains and food debris become sources of bacterial and mold growth in humid environments, emitting a "musty" smell.

When handling moldy materials, you can follow US Environmental Protection Agency's home mold prevention recommendations(opens in a new window)treatment and note the on-site and material restrictions.

Impact on employee health and efficiency

Being in a low-ventilation environment for a long time makes employees prone to discomfort, affecting work performance.

Five practical steps to improve office air quality

Management can take the following actions to optimize the space:

  • Regular maintenance: Commission a professional team to clean central air-conditioning fan coil units and HEPA filters.
  • Air purification: Consider choosing appropriate commercial air purification equipment based on environmental assessment.
  • Deep cleaning: Regularly schedule high-temperature steam enzyme washing for carpets and fabric chairs; we do not recommend relying solely on vacuuming.
  • Control at the source: Restrict eating at desks and strengthen pantry ventilation.
  • Plant purification: Place plants with air-purifying functions, such as snake plants.

The value of professional cleaning teams

Office architecture is complex, and simple daily cleaning cannot solve deep-seated mold problems. If you notice persistent odors, you should first check the air-conditioning or ventilation system, and if necessary, hire professionals to inspect and clean it.

FAQ

Why does the office carpet still have an odor even after daily vacuuming?
Vacuuming removes dry dust and some loose dirt. Where moisture or food residue remains within carpet fibres, assess a material-appropriate cleaning method and drying arrangements rather than assuming every carpet requires hot steam for odour removal.
What happens if the carbon dioxide concentration in the office is too high?
This leads to insufficient oxygen supply to the brains of employees, causing fatigue, inability to focus, short-term memory decline, and reduced work efficiency; it is recommended to increase fresh air volume or improve ventilation.
