Mitsubishi Heavy Industries (MHI) split systems respond to an increasing understanding of the importance of indoor air quality with the inclusion of Clean Air technology.

Clean Air technology is a combination of several specialised components, systems and functions within the split systems designed to work in synchronisation to improve indoor air quality, particularly important for those who suffer from allergies or asthma.

Each individual component has a core function to help deliver clean air.

The Allergen Clear Filter is designed to capture airborne particles including pollen and dust1 with a specially formulated enzyme-urea compound which breaks down the structure of captured allergens and deactivates bacteria2, mould and viruses3.

The next line of defence is the Photocatalytic Washable Deodorising Filter that captures additional airborne particles, such as fine smoke particles, before neutralising odour. It is easy to wash and helps ensure the home smells fresh.

The multi-stage Allergen Clear operation involves the unit cycling between heating and cooling modes to generate internal moisture which in turn activates enzymes within the specialised Allergen Clear Filter. These advanced enzymes then break down allergens and deactivate bacteria2 mould and viruses3 that have been captured by the Allergen Clear Filter. Activated by the ‘Allergen’ button on the remote control, the operation runs for 90 minutes and automatically stops upon completion.

A separate function recommended to be used after the Allergen Clear operation is Self-Cleaning mode to dry the internal components, including fan and filters to help eliminate mould and deliver clean and odour free air. To further prevent the growth of odour causing mould, the internal fan has undergone specialised anti-microbial surface treatment.
