In recent years, as industrialization is advanced and the severity of environmental pollution is increasing day by day, people are continuously exposed to pollutants present in the air not only outdoors but also indoors. This is evolving.

Such an air purifier is a device that purifies the pollutants contained in the air and replaces it with fresh air. The principle of discharging is mentioned. Air purifiers employing this method usually use a fine non-woven filter called HEPA to collect and filter particulates and absorb odors using activated carbon. In addition, titanium dioxide photocatalyst instead of activated carbon is used. There are also models that employ ULPA, which is a finer filter than HEPA.

However, in the case of a conventional air purifier to which a filter as described above is applied, it is very important to replace the filter at an appropriate time in order for the filter to properly perform a function of absorbing pollutants and discharging purified air. Regardless of the reason, the air purifier filter used in a clean space is basically a method of checking the operating time (eg, motor operating time) through the timer in the air purifier and guiding the replacement time after a predetermined time has elapsed. It can make the air worse as harmful substances are discharged from the polluted filter in a poor environment that is replaced unnecessarily even though it can be used longer than other places, or the filter is polluted before the predetermined operating time of the air purifier. There is a problem.

Therefore, there is a need to prepare a method for simply and efficiently checking whether the filter of the air purifier is functioning properly and notifying the user of the correct replacement cycle.
