Helps to clean & maintain itself year after year

FrostWash: Better at maintaining peak performance Over time, dust and dirt build up in your AC, reducing its power. Hitachi FrostWash technology continuously maintains performance by removing dust and dirt from the heat exchanger.

FrostWash double benefits: Preserved performance: Systems with FrostWash show better airflow performance maintenance compared to those without.

Sanitising effects on the heat exchanger: 99% Viruses eliminated, 99% Bacteria eliminated, 95% Mould reduction.

FrostWash process: 1. Freeze the heat exchanger. Frost captures dirt. 2. The unit enters a thawing cycle. Dirt detaches as frost melts. 3. Dirt and mould are washed away with condensate.

airHome 500 & 600: Mould guard function Minimises mould formation & bad odours. When switched off, the mould guard function automatically blows air through internal components to dry them. airHome 600 also heats the coil to improve the process.

Let FrostWash work when you're absent Pre-set FrostWash to activate automatically when no one is in the room (with motion sensor on airHome 600). Control FrostWash remotely via the airCloud Go app.

Easy filter cleaning process airHome's pre-filter can get clogged. A reminder lights up when it's time to clean. The filter is easy to remove and wash.

Long-lasting performance for worry-free comfort

Hitachi Cooling & Heating air conditioners are built to last. Packed with safety & reliability features, airHome air conditioners are engineered to perform through the years.
