It's made out of wood and it has a filter and a 120mm pc-fan to generate airflow throught the filter to help the paintfumes to go to filter. It took about 3h to make, I used a jigsaw to cut the plywood and used a miter saw to get the 45° angle to the stick, then I put the thing together with glue and small nail gun. The fan is held on with regular fan screws, the plywood is 6mm thick. The filter is attached with nuts and bolts. Corners are sealed with silicone.
