Environmental consulting with a focus on air quality

World class indoor air quality expertise

Prezant Environmental is one of Australia’s most respected air quality and ventilation consulting firms.

Our expertise includes advising on air quality management in public buildings, schools, offices, laboratories, industrial and manufacturing facilities, and single and multi-family residential.

Concerns addressed include indoor contaminants with potential health impact: mould, bushfire smoke, methamphetamine residue, and in occupational settings, silica, welding fumes, solvents, pesticides, fumigants, and other airborne or skin contact workplace hazards.

With certification, credibility and authority in public health and HVAC engineering, Prezant Environmental offers a unique combination of skills based on science and public health.

Our services include site visitations, remote assessments, infection risk modelling and chemical assessments. These range from simple air measurements to highly complex assessments, including tracer gas studies using smoke, carbon dioxide, and/or sulfur hexafluoride (SF6) to quantitatively measure air exchange or track contaminant movement through buildings.
