I’ve placed a HEPA air filter and cleaner in the laser room, in the hope that it will reduce the general stench of burned material and also cut down on the ambient dust level. It’s not in any way a substitute for the laser’s exhaust blower, which vents almost all the smoke to the outside. The HEPA filter is just for our comfort when we’re in the laser room.

The HEPA filter has a timer built in. I suggest you set it to run for 8 hours (the longest timer setting) when you leave the room, if you’ve made any smoke during that session. We’ll see how well that works.
