Healthy indoor air

Healthy environment

Low indoor air quality causes health problems. Nakoair® creates high indoor air quality — the inbuilt air filter removes pollutants and humidity while providing fresh natural airflow. "The life you lead is the air you breathe."

Why indoor air quality matters

Indoor air quality measures the health and comfort of the air within a building. According to the World Health Organisation, household air pollution is one of the world's greatest environmental health risks. Understanding and controlling it reduces health concerns.

Signs of low indoor air quality

  • Humidity issues — high moisture encourages mould, dust mites and allergens; timber and structures can suffer.
  • Allergies & asthma — among the fastest-growing chronic diseases in the UK, Australia and beyond.
  • Stale, musty or smelly air; condensation on windows; peeling wallpaper.

How Nakoair helps

By continuously exchanging air and filtering pollutants, Nakoair® reduces humidity, removes allergens and odours, and prevents mould and damp — for a healthier home, workplace or anywhere people breathe.
