You mean an air pump?
Little known fact: if you install a filter facing the opposite direction specified in the instructions, it becomes a super filter, even preventing the passing of the unwanted dihydrogen monoxide. Discovered this once myself.
You’re using the filter wrong, you’re supposed to discard the stuff that passes through it and keep the stuff that doesn’t
I guess it all depends.
Looking for clean drinking water? No.
Panning for gold? Hell yeah.
Silica gel, molecular sieves, air driers, …
Yea but they are less common.
Less common than what? They are all extremely common. Silica gel is in… like every 10th package? There are far less water filters around.
But it doesn’t work for the joke. It just collects the moisture. You wouldn’t put it on your faucet. They want a faucet that doesn’t pump water, so it would be air lol.
Obviously you would not put it on the faucet, that’s the joke. But it would work if you size it correctly. Except that the tiny amount of air that is dissolved in water will still not come out, but the air that was in the filter will be displaced and come out.
