The old saying has it that we are what we eat, but more and more we're finding that we are what we breathe. Air quality in the office can have a remarkable effect on the moral and productivity of the average worker. Studies have shown that more is achieved, people are generally happier and there are less sick days taken, all because someone had the forethought to think about improving air quality in their office. Environment is important when you're looking to make the most out of your office space. Imagine having to come to work in a room smelling of dankness, with little or no airflow and the steadily rising smell of your workmates closing in around you. Add to that asbestos ceilings, poorly cleaned and out-of-date air conditioning and lack of ventilation and it's no wonder people hate coming to work. Here's 6 tips to make sure your office's air quality is on par:

Ventilation and air flow. Many office buildings are built to be closed off entities; they are constructed with non-opening windows and often have two or more doors to open before you enter the main area of the office. In such conditions it is impossible let air flow, let alone feel a breeze. Air flow is important for keeping air from stagnating, and stagnant air is a wonderful breeding ground for bacteria and mould.
Proper air conditioning. A few fans here and there will merely circulate air, leaving staff to breathe the same air over and over again. Air flow must be achieved, meaning new air is introduced as old air is taken away. The best solution is a quality air conditioner or heat pump - something which will actually move the air from the office and allow fresh air in - in combination with an exit for the air, such as a slightly open window or exit to the outside via a duct. This is akin to having two windows open on opposite sides of a house, a breeze will find it's way through.
Maintenance. Having your air conditioners, air filters and vents cleaned regularly will keep them clean and stop harmful buildups of dust and mould deposits.
Humidity. Maintaining a healthy level of humidity is essential for keeping the air in your office healthy: too damp and you run the risk of mould buildup in air vents and in the dark corners of your office; too dry and workers will be parched and uncomfortable. This can be remedied with a dehumidifier or humidifier respectively. Ensure you maintain these in good working order by emptying water buckets when they're full and keeping up to date with maintenance.
Plants. Having a few plants in your office environment will not only perk up the look of the office, it will provide a vital natural air-cleansing system. There are some plants that are better than others for expunging toxins from the air. Talk to a plant store about your needs or, even better, contact a plant hiring company that will ensure the plants are well cared for.
Clean air goes a long way to making a comfortable workplace. If the office is a pleasant place to be in, your employees and workmates will be kept happy and productive.
