Indoor air quality is critical to the health, comfort, and wellbeing of occupants. Pollutants in the air can cause ill-health, irritation, and other adverse reactions to smells or odors, whether at home, in public, or the workplace.

Indoor air quality assessment measures air pollutants to ensure that you are compliant with health and safety standards including Control of Substances Hazardous to Health (COSHH) Regulations. Compliance to these and environmental standards such as LEED, BREEAM, and WELL will demonstrate your commitment to environmentally sustainable buildings for occupants. If dangerous levels of air pollutants are detected, air quality assessment can also help determine a remedial solution. 

Element’s qualified occupational hygienists have extensive experience in full indoor air quality assessments looking at chemical, physical, and biological parameters using a variety of measurement methods. We are also able to provide quantitative face fit testing in according to COSHH regulations.
