Critical lack of understanding
I was researching and researching and decided to get these from hygger. I understand in theory how they’re supposed to work, by creating a pull that forces water through the sponge and the exhaust air and water flor out the top. I cannot wrap my mind around how these things aren’t just aerators with extra steps? Like where does that suction force come from? If the air is supposed to force the water in the chamber into the sponge, how does it filter anything besides the very bottom of the sponge? When i sit and stare at it for several minutes, i swear the only current i see period is the bubbling. I can’t see anything being gently succed into it… just tank “dust” that has settled
Edit: thank you for the input. I understood in theory how they’re supposed to work, it just seemed like witchcraft in practice lol
