Generally, household and general purpose air purifiers only use filters to filter air. The filter screen in such equipment must be cleaned and replaced frequently. The use of ultraviolet mercury lamp can solve this problem to a certain extent, but it also leads to the difficulty of miniaturization.

By combining the deep UV LED with the filter screen, a compact but more powerful air purifier can be achieved.

In hospitals, especially waiting rooms, wards, examination rooms and operating rooms, they must be kept clean to prevent cross infection. Many methods have been used for disinfection, such as filters, chemicals, UV mercury lamps, etc. However, from the perspective of size and safety, the use of UV mercury lamp and chemicals is limited. Deep UV LED is compact and mercury free, which can significantly improve the hospital environment.

In closed spaces where doors and windows are not opened for a long time, such as the interior of airplanes and trains, the risk of air pollution will also increase. Air purification devices usually use filters to filter air. Due to the size and power consumption, it is difficult to realize other methods such as UV mercury lamp to achieve purification.

With compact structure and low power consumption, deep UV LEDs help to achieve a safer and more comfortable space when combined with filters. In addition, deep UV LEDs are mercury free and therefore harmless to humans.
