Duct for Coway Airmega AP-1512HH Air Purifier

I placed my Coway Airmega in the middle of my space under a table, and noticed a lot of air flowing back into the intake of the air purifier. This duct will redirect flow towards the rear of the air purifier so that it works more efficiently.

A small piece of tape (pictured) is required to keep the duct in place.
