  • The black mesh pre-filter is in action, trapping fine dust, bacteria, and viruses that float in the air.

    Pre-Filter

    It captures parts of fine dust, bacteria, and viruses in the droplet

  • A blue UV light glows, sanitizing the pre-filter, which has diligently captured dust, bacteria, and viruses.

    UVnano™

    It sterilizes up to 99.99% of bacteria and viruses in the pre-filter

  • A multitude of 1-3 μm particles has adhered to the surface of the white MERV 13 filter.

    MERV 13 Filter

    MERV 13 Filter removes 1-3 μm particles over 85%, 0.3-1 μm over 50%. It has more than 89.93% efficiency when viruses spread in droplet form (*Based on the result of ASHRAE test)

* Uvnano™ is a compound word derived from the words UV and its unit nanometer.
** Based on TÜV Rheinland test conducted according to LG test method in compliance with ISO 20743 : 2007 removing 99.99 of percent of Staphylococcus aureus, Staphylococcus epidermidis, and Klebsiella pneumoniae from the air conditioner blower fan after being exposed to UV LED lights for 4 hours (tested models : PBM13M1UA, PBM13M2UA, PBM13M3UA). The result value is measured at a specific point set in the experiment.
*** This result may differ in actual use conditions of the air conditioning system.

* Based on KCL test conducted in compliance with ASHRAE 52.2. ASHARE recommends MERV 13-equivalent filters for reducing airborne infectious aerosol exposure.
