The CDC saying it is not transmitted by an airborne route is, as far we know, accurate. That statement however can be misleading if you don't know what that means. It can be transmitted by droplet. In the hospital we generally have three types of isolation. Airborne, droplet, and contact. Here are examples of those.
Airborne - tuberculosis. Isolation is putting that person in a negative pressure room, with 2 doors in series with only one door being open at a time. Gown, Gloves, and N95 mask worn. These are particles that are small enough that basically they can just float and hang out in the air.
Droplet - Flu. Gown, glove, mask (doesn't have to be N95). Droplets disperse with sneezing and coughing, but will be pulled down by gravity, rule of thumb is anything within 3 feet of the patient is contaminated. If you stay more than 3 feet away you don't have to gown up.
Contact - staph skin infection. Gown, glove. Only have to gown and glove if you are going to touch the patient.
You all might already know this stuff, and this isn't hard and fast science.
Part of the problem with Ebola is how virulent it is and how stable it is outside of the host. This leads to the problem where just a small drop of infected blood can cause so much trouble.
