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.
The Dangers of Fine Dust Particles
Fine dust is classified according to the diameter of the dust particles themselves. PM2.5 particles
are defines as having a diameter of 2.5m (micron) or below and PM1.0 particles are defined as having
a diameter of 1
m 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.
LG Clears the Air
LG has implemented a powerful 4-step filtration process to ensure a healthy indoor environment. The
4-step filter kit includes a pre-filter, dust electrification stage, an ultra-fine dust filter and a
deodorization filter. The pre-filter has a multi-layer structure that removes larger dust particles.
After passing through the pre-filter, the air is treated with dust electrification in the second
step, which uses electrostatic force to remove particles thoroughly. In the third step, an
ultra-fine dust filter is implemented to remove 99.9% of PM1.0 particles. Finally, the deodorization
filter removes odors and harmful gases from the air with gas absorption technology. This
comprehensive filtration kit is compact and implemented inside the body of the indoor cassette unit
so that the installation of the kit does not impact the overall size of the unit itself. This robust
filtration system makes the 1-way and 4-way air purification cassettes ideal for schools and
healthcare facilities where people are vulnerable to fine dust pollution as well as in restaurants
and retail spaces where there can be a high concentration of people. The filter kit can also be
removed for easy cleaning and maintenance. Furthermore, with ThinQ connectivity, the filtration
process can be conveniently monitored in real-time from anywhere.

ThinQ connectivity makes real-time air quality monitoring convenient
Providing superior air quality and comfort wherever our products are installed is point of
pride for LG.
As we continue to innovate new solutions that perform to new standards in the industry, we also
continue to ensure healthy environments in line with the requirements of our changing world.
