Responsive to your needs
The Flow A4 uses laser particle sensors to evaluate air quality and automatically adjusts fan speeds as conditions change. This means that you can enjoy cleaner air without worrying about adjusting settings.
Efficient and thorough filtration
Flow A4 is equipped with a multi-stage filter that captures micro-dust(i.e. PM 2.5), odours(i.e. Acetaldehyde) and harmful airborne substances (i.e. Formaldehyde) and lets you know in 2 stages of alert when the filter needs replacement.
Powerful yet smooth air circulation
The spiral outlet creates a robust whirl of cleaner air that circulates the air in the room efficiently and reaches within an area of 53sqm** (based on Japan's JEM 1467 regulations of air changes per hour).
Made to fit smaller rooms, Flow A4 has a minimum noise level of just 19 dB(A)*** when used in Sleep Mode function. Even at maximum speed the noise level is 52 dB(A).
Intuitive and accessible
The Flow A4's simple and intuitive touch UI makes interaction easy to adjust air quality levels you desire.
