Particle Counting in my Laser cutting room.
The Counter starting detecting (MDF cutting )particles almost immediately. It was sighted about 1m away from the machine.
I run a 400CFM grow-room style fan, porting outside. The Counts do drop quite a bit after cutting ceases.
I knew it was going to be a very interesting result but I was gobsmacked. Thankfully I have always worn a 3M respirator & today upgraded to the delux 'Cool Flow' Silicone rubber model ($99)
Within the small room I have fans pointing at HEPA style air filters, and also run a second squirrel cage fan hooked up to a grow-room air filters.
I also created a secondary 'curtain' out of thick plastic sheet, used Velcro to fasten around the pocket-style sliding door.
My Wife said it was the first time she didn't smell anything, and that the plastic was so effective it dropped sound pollution levels in the adjoining room.
Next plan is to start habitually wearing overalls or labcoat to keep the skin exposure limted.
Looooong term plan is to stop using MDF
If this interests anyone I'll do some tests with Plywood and Acrylic
