but wat is the diff bet clean and ion ?
Ionizer is for purifying the air ma.. When they detect impurities in the air, the ionizer will turn on by itself rite.. then they will clean the air by charging dust and smoke particles into positive or negative ions so that they can stick to a charged surface.. Then can get rid of them..
Larger impure particles will totally fall out of the air when two smaller impure particles of different charges clump together..
So I think since it does ionic charging.. so heat is required to gain/lose the electrons to charge the particles ma.. So I think air con becomes hotter during ion mode?

But I think it is attached to our air con de.. so if on the air con.. it will be auto detecting if there's impurities.. So I dun think there's a way to turn it off w/o turning the air con off lei..
But I realise the ionizer often comes on only when I wind down window or open the door when the air con is turned on or when I fart in the car..

This 1 onli my theory hor.... I may be wrong...
