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 phenomena, 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.

We recommend using the following.
1. When you receive the product for the first time, please charge it for more than one hour.
2. We recommend that you connect to the charger before going to bed.
(It is better to charge the battery frequently as well)
The integrated display mode displays PM2.5/PM10/VOC at once in graph form.
If the measured value is “POOR” or greater than or equal to that level, the letters of each item will blink and warn you.
If the alert function is working, the air quality is POOR or UNHEALTHY level, we strongly recommend you to ventilate or wear a mask.
It displays PM2.5/PM10/ VOC.
This mode is displayed in graph form on one screen with 4 steps each – GOOD, MODERATE, POOR, UNHEALTHY.
Each step is divided into 18 steps. (Total 72 steps)
Even if you do not see the numerical value directly, you can see it in 72 steps, which is very intuitive.
If you do not ventilate by closing the door overnight, VOC may be released overnight in a new house or new furniture containing hazardous substances, which may increase the level of the house.
Many products used in daily life can release harmful substances, and the higher the number of such substances, the higher it can be. Volatile Organic Compounds such as formaldehyde are gradually reduced by frequent daily ventilation.
We recommend that you ventilate in the morning, and ventilate more often if the number is high.
Most purifiers filter out more than 99% of PM, but VOC cannot be filtered like PM.
In order to remove VOC, which is a volatile harmful substance such as formaldehyde,
it is most effective to remove the cause or to constantly ventilate daily.
The health effects or symptoms of VOC are;
- Irritating to eyes, nose and throat stimuli.
- Causes headaches, loss of coordination and nausea.
- Causes allergic skin reactions.
- Causes shortness of breath, nausea and vomiting.
- Causes fatigue and dizziness.
- Causes liver, kidney and central nervous system damage.
- Some organisms can cause cancer in humans and animals.
Especially methylene chloride (contained in adhesive removers and aerosol spray paint) is known to cause cancer in animals.
Benzene is a substance that causes cancer in humans.
Indoor sources include cigarette smoke, stored fuel, paint supplies, and automobile exhaust.
Huma-i air quality monitor follows the recommendations of the German Health Ministry, which is divided to 4 levels.
GOOD: 0.000 ~ 0.220ppm
MODERATE: 0.221 ~ 0.660ppm
POOR: 0.661 ~ 2.200ppm
UNHEALTHY: 2.201 ~ 10.000ppm
VOC occurs mainly in household products such as:
- Paints, paints and other solvents
- Wood preservative
- Aerosol spray
- Detergents and disinfectants
- Insecticides, fragrances and pesticides
- Combustion fuels such as volatiles
- Dry cleaning clothing
- Products with glue
OLED display shows VOC measurement value in VOC mode.
To view all measurement results simultaneously, use the integrated display mode.
