Hi, I need some help controlling some odour in my room. My girl is in a cabinet and it has a carbon filter on it but it doesn't seem to be doing the job adequately enough. I know about ONA gel but I can't seem to find it where I am located. The best places I have access to are Home Hardware, Canadian Tire, Wal-Mart, Zellars, etc and some small shops. What is a good alternative to ONA gel that will not just cover up the odour, but neutralize it? Some things I can get are Air Sponge (Air Sponge | Canadian Tire), BrightAir (Bright Air Odor Eliminator, 14-Oz | Canadian Tire). Any help is greatly appreciated!
