Other methods to get rid of smell with Flowermate V5.0s?

Hey guys, I got a flowermate about a month ago and I've been looking for ways to mask the smell. Right now I'm using both Ona Gel Pro from here: http://www.amazon.com/Ona-Gel-Pro-1-Quart/dp/B00AC1N4DM/ref=pd_bia_nav_t_1?ie=UTF8&refRID=0122WHDBP2N6VXVSV3JE and a sploof from here: http://www.sploofybrand.com/ but I'm not sure else how to hide the smell of cannabis.

Recently my roommates said they smell weed from my room all the time when I was only using Ona Gel and blowing vapor out the window. After hearing this, I picked up a sploof to help mask the odor more but I'm still worried about the smell coming from the Flowermate itself and wondering if the sploof covers all the smell of the vapor.

Does anyone have suggestions on masking smell coming from the flowermate itself or suggestions in general? I'd vape outside but campus security is always around.
