– 3X better at maintaining the performance of your AC
Hitachi FrostWash technology helps to maintain the performance of your AC for years to come by freezing dust and dirt, melting it and washing it away. Our tests show that systems with FrostWash are 3X better at maintaining air flow performance than those without this technology[1].

– Vector DC Inverter technology
With inverter technology, an air conditioner cools with maximum capacity at start-up, then automatically slows down and operates at a minimal capacity to maintain room temperature at a comfortable level. Non-inverter models can only operate with simple on-off controls. Trying to maintain the desired temperature by repeatedly switching power on and off consumes much more electricity and results in bigger temperature fluctuations.

– Adjusts temperature as you arrive home or leave the house
With the airCloud Go app you can also connect to your smart speaker (compatible with Amazon Echo and Google Home), use weekly schedule and timer functions and see how much power has been consumed with the integrated Energy Cost Estimator.
– Discover how to install airHome 400
The airHome 400 series combines award-winning design and great air conditioning performance. The FrostWash self-cleaning feature enables to remove dirt, mold & contaminants from the heat exchanger coil. airHome 400 can be paired to airCloud Go app via wifi, for remote control and energy cost monitoring.
[1] Two identical units were tested for comparison; with and without FrostWash. Test chamber simulated approx. 2 years of dust and oil build up which may be experienced in a typical home environment. Airflow performance was tested before and after being in the chamber. Unit without FrostWash experienced an 18% drop in airflow performance. Unit with FrostWash experienced only 6% performance drop. Tested at Johnson Controls-Hitachi Tochigi factory, Japan Nov/Dec 2021
[2] ViroSense Z1 filter shows 99.9% of effectiveness against SARS-CoV-2 NIID isolated variant: JPN/TY/WK-521 and 99.0% effectiveness against Influenza A Virus (H3N2) tested at Japan Textile Product Quality and Technology Center using ISO18184:2019 method. FrostWash technology also showed 99.0% reduction of virus particles on the heat exchanger tested at Kitasato Research Center of Environmental Science
[3] Claim refers to the effect of ViroSense Z1-filter (optional on some models) which showed 99.0% reduction of Staphylococcus aureus NBRC12732 and Escherichia coli NBRC3301 bacteria particles under lab conditions tested at Nissenken Quality Evaluation Center Japan, and also FrostWash technology which showed 99.0% reduction of bacteria on the heat exchanger tested at Kitasato Research Center of Environmental Science Japan
[4] Requires installation of external airCloud Go adapter
