on recently day Free catch ill similar to air condition change but just persist in room

after few day all clothly thing wash and change but issue still persist

until one day sudden think about air perifier and change the filter for new one

the old old was cover in thick dust after change attempt and leave it run in few hour

the world in much better and the handache gone

Free just think it's recently change the filter, but not sure how long it take since last maintainance

but this time Free just learn about reset the filter counter which not automatic like another one.

stay in clean air for better life
