My apartment came with a new, fairly high-end Samsung air conditioner. There's a function called 청정 which I usually run when the air pollution is bad outside. As far as I understand it, it's not an air purifier - there's no filter to change, and the air doesn't get sucked in first. I know this is a very unsophisticated theory, but it seems like the machine produces "new" air and just blows it into the room.

Do any of you have a similar air conditioner, or know anything about this? I know a high-powered air purifier would almost certainly be better, but I'm curious about what the 청정 actually does.

If it was air cleaning function, it would be 공기청정.
My samsung also has a 청정 function. What it does is to dry the cooling surface which is wet from all the condensed moisture, so it wouldn't have some nasty mould growing on it. Basically it's just working as a simple fan, no cooling. Whenever I turn off the A/C, I let it run for about 30 minutes on ''cleaning''.
It's fairly standard even on older units. On my previous LG it was called ''drying''.
Those units that have air purifying capabilities have replaceable filters.

Ha! Okay, thank you. I feel kinda dumb now. I think I asked a Korean friend about it a while ago and they told me it was for air cleaning, but probably assumed it was preceded by 공기. Just ordered a new air purifier!
