Over time dust and dirt can build up in your AC reducing the amount of air that can flow through it and making it less powerful over time.

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].

Stop the causes of AC odors

Heat and freezing shock, extreme humidity, torrential rain, voltage surges, lightning strikes, impacts and more… every air conditioner we sell has been tested to the extreme. In addition, our unique SafeGuard System combines electrical and mechanical systems to protect the outdoor unit from extreme weather and voltage fluctuation. These protections include a 3-minute delay circuit to prevent damaged caused by multiple fast re-starts in the event of power cuts, an ODU valve cover to channel water and condensation safely away from the outdoor unit, anti-rust paint and heat fins, and a metal fireproof electrical enclosure to protect electronics inside the outdoor unit.

Combining 3 different air purification technologies for enhanced effectiveness against pollutants including viruses and bacteria and even odors. The pre-filter, air purification filter and heat exchange cleaner work together with up to 99.9% effectiveness on viruses including SARS-CoV-2^[2], up to 99.0% effectiveness on bacteria^[3]

Our Cascade Vector DC Inverter System is equipped with a microchip to control the speed of the compressor. A split rotor with displaced electrical poles enables electromagnetic noise suppression and optimizes low-speed energy-efficiency.

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.
