If there is a purifier, put it on the purifier outlet.
If the measured value is less than 10 units, it will work normally.
Another method is to rub the tissue on the suction side of the device to generate dust, which can lead to an increase in the PM10 value.
If you smoke, the numbers will go up tremendously.
However, smoking is harmful to your body, so please do not try it in this way.
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 for a while 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.
The life span of VOC or CO2 gas sensors is 10 years.
In case of White model,
We recommend that you charge through USB cable provided by Huma-i.
When using mobile phone charger, it is better to use the charger which is more than 1A.
In case of Black and Skyblue model,
You can use the mobile phone fast charger due to the built-in high-speed charger protection circuit.
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.
It is possible to use 3 hours of continuous use time in one charge in case of white model
and 2 hours in case of black and skyblue model.
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.
Protective film is attached on 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.
