Rudy, those things are designed to collect and filter predictable fumes from welding steel and iron and the welding rod flux coatings.

They are not designed to work the heavy / hazardous metals like cadmium, lead and the dozens of other colorants used to give glass the wonderful colors and characteristics that make it useful in lamp working.

If, and its a big if, the filtering system could capture the hazardous fumes from lampworking then you would wind up with a highly contaminated filters that would need to be properly disposed of at a hazardous waste facility.
That will get really spendy really quickly and become a pretty much a night mare for the disposal place because you will have an unknown mix of chemicals that will each have to be treated differently.

You are going to be much better off using the "dispersal and dilution" that a high velocity ventilation system will give you.
There is a great deal of information in the safety conversations here about setting a system up but the theory is that moving a large amount of air from the torch will pull gas burning fumes and the off gassing colorants outside to mix with the air which normal winds will carry away to mix with massive quantities of clean air and this reduces the concentrations down to extremely small amounts that can settle back into the ground in nearly untraceable amounts as long as you are not running a factory producing tonnes of material a year.

But if you don't mix large quantities of air at fast enough velocities then you just wind up spraying it on your lawn and the roofing and side of your house and you wind up with contaminated surfaces that have to properly treated at a hazardous waste facility at great expense.

Another thought is that if such filtering systems worked then the you would see them in use at the larger teaching studios and at commercial glass facilities.


I wish I had better answers but the science shows that the quick fixes just don't work.
