You raise an issue that has been bouncing around my mind. How do you dispose of an old carbon filter? You can't just chuck it in the recycling bin, now can you... Mine is rate to last for 3 years at full CFM and as I'm using at about 2/3 the rated CFM I expect to get well more than 3 years but then what? It's frikkin' huge. I guess I'll be looking for an unattended dumpster when the time comes...

My buddy has a 10" inline ozonator and the damn thing works a charm. There is no particle buildup, or he hasn't complained of any. My guess is the fan blows it 99.9% of it out of the vent. The problem with Ozone is that it is toxic. You have to vent externally. Oh and you have to replace the lights every 18 months or so which has costs too.
