Hitachi's 4-way Cassette Air Conditioner - Innovative Solution for Discrete and Precise Airflow
In 1983, Hitachi invented the 4-way cassette air conditioning unit, which is an innovative solution for clients who want a visually discrete AC system where a ceiling plenum is available.
For home users, Hitachi's 4-way cassettes are an excellent option for minimizing the visual impact of an AC unit without incurring the cost of installing ducted units. Today's models deliver precise airflow in all four directions and feature optional occupant sensing technology, which automatically saves energy if a room is empty.

– Healthier, cleaner air from your room AC
Choose from our range of air conditioning for single rooms, with up to four different air purification technologies. The pre-filter, air purification filter, heat exchange cleaner, and ionizer all work together to achieve up to:

• 99.0% effectiveness on bacteria [2]
• 90.0% effectiveness on odors [3]
• 98.7% effectiveness on allergens [4]

– ACs that can now clean itself
Hitachi FrostWashTM, available on many of our models, maintains your AC performance for years to come by freezing dust and dirt, melting it and washing it away. ACs with FrostWash are proven to be 3X better at maintaining air flow performance than those without this technology[5].

ViroSense Z1 filter shows 99.0% effectiveness against Influenza A Virus (H3N2) tested at Japan Textile Product Quality and Technology Center using ISO18184 method. FrostWash technology also showed 99.0% reduction of virus particles on the heat exchanger tested at Kitasato Research Center of Environmental Science
[2] Air purification technologies may differ by products – see individual AC product information for further details.. 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, and also AQtiv-Ion (optional on some models) which showed 99.0% reduction in E.Coli particles tested at Boken Quality Evaluation Institute Japan following JIS Z 2801 standard
[3] Air purification technologies may differ by products – see individual AC product information for further details. Claim refers to the effect of AQtiv-Ion (optional on some models) on various odors including a 90.0% reduction in formaldehyde, tested at Kinki Bunseki Center Japan

Following JIS-L-1920.standard, Cedar allergens (97.1% reduction), Mite allergens (79.7% reduction) and Dog allergens (94.9% reduction) all tested at the Institute of Tokyo Environmental Allergy Japan.
[5] FrostWash availability may differ by products – see individual AC product details for further information. Claim is based on 2 identical units 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.
