Laser Cutter/How to clean the exhaust filter
When standing in front of the laser, above and to the right is the larger pipe leading to the shop fan.
The green filter attached to this pipe needs to be cleaned 1x per month.
Use a step ladder, take down the filter and vacuum using the laser shop vac that has the HEPA filter installed.
Ladders can be found in electronics, please be sure to replace it if you borrow it.
