So given room size and cash limitations, I wasn’t going to install a standard air filtration system for the Nomad. So my roughly $150 approach was as follows:
1- Seal possible escape routes for the dust with top quality (audimute) weather stripping (except the fan and other necessary apertures). Since I was also using some soundproofing materials like audimute’s peacemaker rubber sheeting with duct tape this not only had the benefit of noise reduction, but also dust containment. Here’s a video showing what this looks like
2- Buy a shop vac, seal all air crevices with Gorilla tape, and add a special HEPA filter in the back for the air to go through https://www.amazon.com/gp/product/B0100FJ7E4/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 Just as with the Nomad, I also added 3.2mm peacemaker to make it quieter, which worked quite nicely.
3- Get a Holmes True HEPA Air Cleaner for medium rooms https://www.amazon.com/gp/product/B000H0Y5XQ/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
4 - A Comfo Classic mask with cartridges (which I already had)
