If the value is "0" during measurement, a purifier is operating properly.
If "0" is continuously displayed, the small particles in the sensor area are occasionally stuck to the sensor side due to electrostatic phenomenon, which prevents normal measurement. In this case, blow off the suction side of the device, located on the left side of the product front, strongly 2 or 3 times and it will work normally. If this is not the case and you keep seeing "0", please contact the customer service center nearby.
It is designed to automatically power off when there is no operation for 10 minutes to protect battery life.
If you want to use continuously, then press the power button lightly to extend the use for another 10 minutes.
The automatic power-off function does not work when the power cable is connected.
Huma-i shows the air quality level in real time as the internal fan is actively and constantly sucking in the air just around you.
The fan sounds a faint vibratory tone.
If you rub the tissue lightly on the fan inlet, you can see that the value changes in real time.

Basically, fine particles of water coming from a humidifier are perceived by optical sensors as fine dust, which is also seen in high-end equipment. We recommend that you turn off the humidifier and measure. Even on rainy or very humid days, the fine dust measurement is a little higher on the same principle.
For accurate measurement and prolonged use, you can keep the sensor clean by blowing the air intake part 2 ~ 3 times with strong wind. When storing for a long time, please keep away from dusty or humid place. Since the sensor is an optical device, it can be used for a long time if you think of handling the optical device.
The fine dust sensor has a life span of 10,000 hours and can be safely used for more than 2 years on a regular basis.
In case of white (HI-100) model,
We recommend that you charge through USB cable provided by Huma-i.
When using a mobile phone charger, it is better to use a charger which is more than 1A.
The fine dust levels provided by the Meteorological Administration and Smartphone application are basically measured at more than 10m above the ground and are provided by a specific measuring station installed in specific area. Our device measures the air quality just around you in real time.
Huma-i provides a display mode that meets World Health Organization (WHO) recommendation criteria.
Especially infants and elderly people with weak immunity are strongly recommended to use WHO mode.
Huma-i basically uses a rechargeable lithium-polymer battery.
Assuming that you use it for 10 minutes each time, it can be used about 15 times when fully charged.
(It may vary depending on the battery condition.)
If you use a portable auxiliary battery, you can use it much longer.
ICON mode automatically selects and displays poor level between PM2.5 and PM10 values.
The protective film is attached to the display screen for product protection.
This film is a protective film for scratch blocking that can occur in the manufacturing process.
If you remove the protective film after receiving it, you will be able to see a cleaner screen.
