Our car aircon already comes with the ioniser.
Ya, i am aware of that but I think our Latio aircon ioniser is not strong enough,

and moreover the ioniser function in the aircon is not always on.
if i am not wrong, it switches on/off like 20min interval?
you can see it on the screen "Ion" when it is on.
this Maier one wil help remove odour faster.
i always on it when i tabao food in the car,
other times, i did not on it.
iagree,
i think the retail price is abt $45.
but tat time my friend got for me in a group buy from another car forum at abt $35.
