I have goggles too and duct tape to cover the vents
Yes I do own a respirator/n100 filters, The respirator came in a little plastic bag with cord around the exit you can pull to tighten it up (like swim trunks), the P100 filters came in a sealed plastic bag.
The ventilator itself smells like rubberish shit and is pretty damn uncomfortable. The way it seals to the face is pretty neat though and definitely better than dust masks.
The 3m 6200 respirator was only 8.30 on amazon and the filters only 4.99. The shipping costed more than the materials.
