Indoor Air Quality Testing

Indoor Air Quality Testing (VHA Ventilation Hygiene Risk Assessment)

Ensure the air your occupants breathe is clean and healthy through routine IAQ testing:

What is IAQ?

The purity of indoor air, influenced by:

  • Particles: Dust and dirt (particulate matter)

  • Gases: Carbon monoxide, carbon dioxide, Sulphur dioxide

  • Liquids: Microscopic droplets suspended in the air

Key Influences

  • External pollution, building location, and occupancy levels
  • The performance of HVAC systems and AHU filters
  • Poorly maintained ductwork

Health Risks

  • Pollutants can cause drowsiness, allergic reactions, and serious illnesses
  • Contaminated ductwork can foster microbial growth, increasing health hazards

Why Test?

  • Contaminants are often invisible and odorless
  • Regular testing ensures efficient ventilation and overall system performance

Testing Methods

  • Standard VHA: Visual surveys, deposit thickness tests, and photographic evidence

Regular IAQ testing is essential for maintaining a healthy indoor environment.
