I don't want to start a war on here - this is just a personal preference - but I am looking for options to do HEPA filtering around a BigBox. There are a couple of printers on the market now that have it built in. However for a BigBox I would need to either buy a 3rd party enclosure like this one (which I am willing to do if the price is right) or build my own (with no power tools). The reasons for wanting a HEPA filtered enclosure, if you are interested: Maybe the ultrafine particulates / particulate matter (UFPs) from 3d printers will turn out to be harmless but I am not confident about that yet and prefer to play it safe. My home (I think most homes in Japan) are not well ventilated - central air is mostly non-existent and room units are not usually run continuously. That leaves doors and windows which are not reliable enough to provide 24h ventilation. Besides the UFPs, printing odors (including PLA) will probably get the printer kicked out of the house quickly. Printer vs Typhoon is not something I want to see. Also due to the small living space, any reduction of noise is welcome. An enclosure is or can be latched to protect the printer from inquisitive minions. If you have any ideas, either 3rd party or something that can be made relatively easily, please share your ideas here.
