Air purifier for snake cage?

Okk..My mom says my snake cage smells to much. I change it out about once a week and clean up its leavings when needed. Now I dont know what the smell is. I personally dont smell anything but she says she does. I cant conivnce her otherwise. Now I have a fifty gallon tank and looked at some air filters here are the sites. http://www.sourcingmap.com/mini-portable-ionic-fresh-air-purifier-cleaner-p-30913.html and

Now my question is, is this safe for the snake. I plan on attaching it to the cage with some sticky things i can get at wal mart. they have Velcro that will attach to the filter and then attach to the Velcro on the cage. Any concerns i should have. & the snake cage does not fit in my room. its currently in the living room. next to the kitchen
Ok..None of you answered my question. Is it safe??
