How healthy is your air?

Poor air quality can have a serious impact on workers’ health, wellbeing and productivity. This impact may be caused by too little fresh air or over zealous heating or by more sinister risks that may be associated with the nature of work, such as respirable dusts or VOCs.

Employers have a duty of care to make sure these impacts are minimised through measurement, testing and monitoring.


  • Indoor Air Quality Audits

    Certifact can provide Indoor Air Quality audits within a regular monitoring programme or investigative surveys in response to a particular issue.

    All audits are carried out by qualified inspectors, with an extensive background in building and environmental services. All incubation and analysis of microbiological samples is undertaken by appropriately accredited UKAS/NAMAS specialist laboratories.

    We are able to measure the basic environmental factors such as temperature, relative humidity, carbon dioxide, carbon monoxide and airborne microbiological activity or more advanced factors such as ozone, volatile organic compounds (VOCs), chlorine, airborne particles & microbials, respirable dusts, oxides of nitrogen or sulphur dioxide.

    We can also undertake odour threshold analysis and provide local exhaust ventilation (LEV) inspection and tests.

    We work in a variety of building types including enclosed workplaces, theatres, cinemas, shopping centres, hospitals, clean rooms, stations and airports.
