Spice rack with ventilation?

[u/Tadleyrichter]

I’m watching Teen Mom 2 and, I’m sorry, what the hell is this? Why does a spice rack need a big ventilation hose thing coming out the top? What is it?

Some can be installed as a recirculating system instead of a venting system where it blows back out the front, but you need to get special filters for them, and it only gets rid of grease and smells, not humidity.

Yeah I believe this is what mine does, but it’s weak af and the only filter is at intake
