I’m a little bit confused by this video because it seems to be comparing your filter to glow forges filter but their filter allows you to use the glow forge anywhere in your home without a window. I think that’s why people spend money on it.
THIS IS NOT A FILTER, it's just a way to exhaust your fumes faster and further, and really the best thing about it is you can turn off the glowforge fan that sounds like a jet engine. BUT -- THIS IS NOT A FILTER --- This is just an external fan for exhaust. If you are not buying filters for a filtration system, or cleaning off some sort of removal filter, then it is not filtering anything.
