In recent years, we’ve seen a significant increase in the level of fine dust particles in the air in different regions throughout the world. Fine dust has been linked to respiratory disease and is particularly harmful to more vulnerable populations such as children and the elderly. While there are efforts being made by regulatory bodies and companies to reduce the emission of these harmful particles into the air, it is vital to protect ourselves from fine dust and contaminants not only outdoors but indoors as well. In order to provide more healthy environments for commercial facilities, LG has released 1-way and 4-way cassette applications with powerful air purification capabilities.

Fine dust is classified according to the diameter of the dust particles themselves. PM2.5 particles are defines as having a diameter of 2.5μm (micron) or below and PM1.0 particles are defined as having a diameter of 1μm or below. The smaller the fine dust particle, the more capable it is to be absorbed into the lungs and into the blood. These particles contain heavy metals and hydrocarbons that are detrimental to our health. Organizations such as the WHO and UNICEF have reported that as many as 1 in 10 people are exposed to fine dust particle pollutants and the deaths of as many as 130,000 children can be contributed to air pollution. While taking the dangers of fine dust particles into consideration, LG has implemented robust air purification filtering into their 1-way and 4-way cassette units.
