State is serviceable condition (the second state), the non-completely new filter core being as able to use.It is small in the purification efficiency of air cleaning facility
In the case where second threshold p2, it can determine that the use state of filter core is to use up state (third state), as scrap filter core.
Further, it is also possible to which it is p3 that third threshold value is arranged between first threshold p1 and second threshold p2, set in air cleaning
In the case that standby purification efficiency is greater than third threshold value p3, it can determine that the remaining life of filter core is greater than 50%, and it is net in air
