Checking the Dust Concentration

You can check the airborne dust concentration by its particle size.

Press the Indicator button during the operation.

  • Whenever you press the button, the display changes in the following order: PM10 ~ PM2.5 ~ PM1.0.

  • The concentration of the selected dust particle is displayed for about 10 seconds.

Note

  • PM (particulate matter) density is displayed in increments of 1 unit, from 8 to 999. PM density values are based on the data sheet provided by the sensor manufacturer.

  • The PM10 and PM2.5 air quality values follow those provided by the United States EPA (Environmental Protection Agency) for 2015.

    • The overall air quality level displayed on the product may differ from the level announced by the EPA.

  • The PM1.0 density is displayed in the same manner as the PM2.5 density and is based on LG Electronics standards.

  • The PM10 and PM2.5 densities displayed by the product could differ from the EPA forecast and from densities measured by other products or devices.

    • Differences in PM density values may be the result of different methods of measuring or differences in the actual PM density levels.

    • The PM density measurement was tested using LG Electronics’ standard test materials.

  • Using the product near a humidifier, mist generator, air-conditioner or other device which generates steam or micro-particles could affect the PM densities.

  • The overall air quality level is a result of both PM densities and the odor level. It may differ from the PM10, PM2.5 and PM1.0 density levels.

  • Even two products placed in the same space could measure the PM10 density differently due to air circulation.

  • The chemicals contained in air fresheners, perfumes, deodorizers or cosmetics may affect the overall air quality display.

  • The dust density displayed may change with environmental factors such as the presence of sofas, beds, carpets, vacuum cleaners, humidity, smoke, bugs, pets or cooking oils.

  • The PM densities may be affected by changes in the outside environment such as construction, heavy traffic or pollen.

  • The micro dust density could be higher near outside doors, windows, vents or in areas where outside air enters.

  • Use ONLY water to clean the sensor. Using anything else could cause product failure.

  • The fine dust density could be affected by cooking or using humidifiers, sprays or other products which generate steam or fine particles.
