Measurements are being made, but OLED display in ICON or PM mode shows PM2.5 & PM10 value.
To view all measurement results at the same time, switch to the integrated display mode.
Or switch to VOC mode to see VOC result.
Due to the nature of the gas sensor, VOC values can be measured slightly higher or lower when power is on, which is normal.
The longer the neglected period is, the longer it may take to stabilize.
If you do not use it, you can keep it charged for more stable use.
VOC sensor requires time to stabilize.
It takes about 15 ~ 60 seconds, and it usually shows the measured value about 15 seconds.
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 and measure. Even on rainy or very humid days, the PM 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 the 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 PM 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 sensor is 10 years.
You can use the mobile phone fast charger due to the built-in high-speed charger protection circuit.
The PM 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 a 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 12 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.
