Indoor air quality is a serious issue, not only for individuals but for businesses too. Poor air quality can cause sick absence to rise by up to 50% and that's bad for business.

With the UK population spending up to 90% of their time indoors, the quality of the air we breathe is crucial. Studies have shown that people who live and work in indoor environments where the bare minimum airflow requirements are met record significantly higher sick absence than those who stay in well ventilated premises with good air quality.

Cheaper ventilation systems and downsized fan capacities have combined to produce increasingly unacceptable situations. A well functioning ventilation system should be:

• Well suited to its purpose and fulfil all the legal criteria.
• Dependable, safe, reliable and have long-term functionality.
• Economical, highly energy efficient and cost effective.
