So someone over at another forum came up with this idea, and while he may have been kidding, I think it could be a very marketable idea. All of us constantly talk about wanting a clean vapor path, a clean air path. We tout that glass on glass is the cleanest route to get our vapor, but what about the cleanliness and the purity of the incoming air before it gets heated? What if someone designed a vape that incorporated a hepa filter where the air first enters the vaporizer to filter out any airborne contaminants along with a glass on glass vapor path? Hell, they could even market an optional accessory that would allow you to bypass the filter and hook up a small oxygen tank for the purist vapor that can be found anywhere. Hey, as crazy as these ideas may seem, there is another level that vaporizer manufacturers can explore that hasn't been done yet, eh? A vape such as these would be a perfect medium for those who have lung issues or compromised immune systems let alone those of us that want the cleanest vapor possible, eh?
