Air is an essential element for our lives, and we breathe air every moment we breathe. In particular, air quality, which is an essential element for our lives, affects our health. Recently, as the frequency of air pollution such as fine dust increases, interest in air purifiers is also increasing.

In general, an air purifier is a device that purifies polluted air in an indoor space and converts it into fresh air. Since it is used in a fixed form at a specific location in the indoor space, the air purifying effect is limited to a limited range of installed locations depending on the capacity of the air purifier. and due to the air cleaning effect of a limited range, it is necessary to install a separate air cleaner according to the size of the indoor space, and thus the user has a great burden in terms of cost.

In addition, a fire alarm is a device that detects the occurrence of a fire by heat or smoke. It is provided in the indoor space and provides an alarm in case of a fire to quickly inform people in the indoor space of the occurrence of a fire. In situations where it is difficult to secure visibility due to smoke or flames, it is impossible to identify emergency exit signs and guidance lights, or it is not possible to move quickly to the evacuation site or exit due to misrecognition of emergency exit signs and guidance lights, resulting in life-threatening accidents. .
