Hitachi AC key features and technologies

Fresh air

iFresh Frost wash Technology

With the help of dew collected from the air moisture, Frost is created in the indoor unit to cover the heat exchanger. Accumulated Frost then melts and washes away the dust attached to the heat exchanger. Later it dries up the heat exchanger resulting in clean and hygienic air all the time.This unique self-cleaning function removes dust and unwanted particles you might not even be aware of.

Benefits of this technology.

Dusty and humid air conditions become home to bacteria and oily grime. This can create unwanted order and reduce efficiency and performance. Frost wash eliminate dust and bacteria to keep your unit running at optimal condition giving you clean air for longer. The humidity sensor inside your unit checks the indoor moisture level before starting the Frost wash. If the access level is detected, the drying operation activates to ensure no water droplets are formed anywhere on your unit.

Frost wash will be started every 70 hours on the accumulated use basis. You can operate Frost wash whenever you want to, by simply pressing the button. Frost wash LED indicator acts as an alert to suggest operating Frost wash after 70 hours of AC uses.

Clean air

iClean auto filter cleaning Technology

Dust gets accumulated on the stainless steel filter over a period of time. The brush attached to the filter cleans it automatically at regular intervals. The dust catcher, which is located on the top of the dust box, sweeps the dust into a dust box. Once the cleaning is over, the brush move bags from the dust collector box to its home position. The auto cleaning brush moves twice over the dust Catcher to increase the dust transfer capacity.The auto filter cleaning ensures that there is no dust left on the filter. And so, the air that meets the AC is free from dust and air coming out of AC is always clean and fresh.

Benefits of this technology
