But I believe it is very expensive. LG mentioned this clean room and cabinets including all the equipment such as filtration to suck up the dust and replace it with pure clean air are so expensive. That may cost hundreds of thousands or even millions easily. I am glad, NWBO only require Class 2 clean rooms and with Flaskworks microden, the clean room space requirements I believe would be a lot less. That by itself will cut a lot of cost. No wonder LG was smiling with twinkle in his eyes after they bought the Dendritic Cells manufacturing company. All imo.
