I use it when I smoke my cigar at home and it is perfect.
The Comgrow Metal Smoke Purifier Absorber unit is actually quite good for working with soldering equipment and laser diode machines. Its not excessively loud and has a variable speed control. The unit was smaller than I anticipated from online photos but it functions well. The only issue I see is the availability of replacement filters atm. It comes with a couple of adaptors and extraction hoses of different sizes. It is fully compatible with the Comgrow Laser Enclosure Unit which just sits over your Diode Laser Assembly. I am going to be purchasing a second unit soon for my new Laser Diode Machine.
