Tee,
I think what you are calling "air roots" are reg roots that are looking for something to grow in. They look to be coming out of the bottom of the upper joints and hanging down. ."Air roots" should be curling around the closest thing looking for support help. or at least reaching upwards.
This is just my opinion.
Masud:
I personally don't think you will be able to get any of these Hybrids to cling to a wall and grow upward like the Epies. do. Can't comment on the true plant species because i haven't had any experience with them..
I usually have 100 or more at any 1 time and have never seen 1 that has put out holding type roots in Schlum. Hybrids
These are my opinions on this so please don't take my comments as argumentative

Here's a closer look at some:
