Any experts with experience here?
The one i usually use is out of order, but at the back there is a filter tank thing, looks like a scuba tank with a black cover on. Water comes out slowly.
I just tried another new machine, water flies out fast and at the back no visible filter, just can see a connection to the external water pipe.
How can you tell if they have a filter? and is it inside, outside or maybe both? or no filter at all
