Selling brand new air purifier for laser and 3d printers. Comes with everything you need to get up and running so you can engrave and print without having to worry about the harsh chemicals. I also have 2 prefilters and 1 medium filter and a spare motherboard I am throwing in. Bought two of them and only needed one. asking what I paid minus shipping. Also willing to trade for gun related items. If interested let me know the worst I can say is not interested.
