Aquasafe filter order?

[Midknight]

Ok, I need help with mine.
I just replaced the bottom 3 filters but couldn't find the top 2 filters.
Not even sure what they are called.


So if someone can tell me what they are and if they can be ordered from the same place then I am in.
At this point I have disconnected the top filter as I was and still am getting maybe 2 gallons a day out of this.

TIA
