How can they keep out dust and airborne particles if they are vented?

There is a light foam layer which (apparently) aids in ventilation and allows the goggles to keep airborne contaminants from the enclosure.

They have small vent holes on the bottom that are angled in a way that makes it difficult for dust to get in, not impossible.

Yes they do a pretty good job overall of keeping particulates out. I Use them for cement dust. Nothing is 100% when it's that fine.

I store my gas cans under a lean-to outside, and I hang this on a nail in the back. So far dust hasn't been a problem. but maybe a long sock would be good. Let the air circulate, but keep dust out.

Jen is correct, it's just a low vent on the back. It zips down if you don't want it open. But, it is perfect, when open, to put a fan in front of it and keep some fresh air flowing through.

It is designed so it doesn't block the vents. My laptop doesn't get any hitter than it does without the case.

Nothing will keep the dust out except a totally sealed cab enclosure. This dust guard helps a ton and is the best one you can buy. The dust will always be there because of tires moving it everywhere.

ventilation air filters, well...they filter air, generally. Some work better than others.

I use a broadcast spreader, such as Dustmizer. Wear a breathing mask while doing this also.

I'd leave it in to protect the exhaust parts of the vacuum. When it's operating obviously there is air being drawn in and therefore exhausted. If you don't use the dust bag you are first putting a lot of very fine dust right back into the air and second not filtering the air going through the machine.

I put mine in the path of the air blowing from a vent and it worked very well. The vent forced air towards the unit and then the unit cleaned it and spread it throughout the room.

it has 2 vent holes. one on bottom and one on top. then it has a few ports for plugs and wires. these ports tie up onto stuff so you could use them for extra air filtration if you wanted.

There aren't any "vents" per-say, you can direct the air flow left to right via "finns" controlled by a tab above the discharge port. It works well enough.

Living in Beauty has it covered. Make sure the small vent release is not sticking. It should be loose until it pops shut.

What? You intend to cover up the windows or something? If so you probably could, but you would need to leave a few inches of space for air circulation or mold might grow from condensation.

The unit has a fan that makes noice when venting to prevent from getting hot when use.Hope this helps.

It has slits on the sides and slits on the bottom piece for ventilation. Air flow isn't an issue with these. I wouldn't worry about that. I still think this is the best deal.

just blow it off with compressed air, theres seals underneath to keep foreign objects out. However Ive had mine in the deserts of Peru being absolutely abused to years with no, absolutely NO maintenance, and the thing just keeps going like the little train that could ! ! ! ! An excellent investment for harsh environs.
