  • Since the sensor is mounted inside the product, the measurement time may be delayed.
    Depending on the external temperature, the measurement time may be different.
    The measurement deviation is 5% ~ 10%.

  • The integrated display mode displays PM2.5/PM10/VOC or PM2.5/VOC/CO2 (black model) 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.

  • Skyblue model displays PM2.5/PM10/ VOC.
    Black model displays PM2.5/PM10/VOC and PM(PM2.5 and PM10 AUTO)/VOC/CO2 with two kinds of integrated display mode.

    This mode is displayed in graph form at 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 fine dust, but CO2 and VOC cannot be filtered like fine dust.
    In order to remove CO2 or 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.
    Or switch to PM (Particulate Matter) measurement mode to see fine dust concentration.

  • Measurements are being made, but OLED display in ICON or PM mode shows a fine dust/ultra-fine dust 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 or CO2 values can be measured slightly higher or lower when power is on, which is normal.
    The longer the neglect 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 and CO2 sensors require time to stabilize.
    It takes about 15 ~ 60 seconds, and it usually shows the measured value about 15 seconds.
