Ventalation for air tight cargo trailer/camper

I've finished my cargo/trailer/camper build. I've noticed when I turn on my Maxxair fan it struggles due to lack of outside air. If I crack a window it makes a HUGE difference. I haven't hit the road yet but I'm assuming if I'm in Quartzsite with a window open the whole place will fill with dust. Any ideas on a filtered outside air intake?

As a quick solution until you come up with something better, a furnace filter over the opened window. Elastic bungee will hold the filter and allow it to be removed.

something as simple as this will help. About 10 dollars or so. You can go up from there as far as models and vents .

I put two of these in my cargo trailer one up high and one down low at opposite corners. When I travel on dirt roads I put duct tape over them to keep the dust out. I've never had dust come in when stopped. But as mentioned above a piece of hvac filter over would help of you're worried about it. I purchased mine on Amazon for $5.99 ea.

Those vents would work but I'm concerned about the dust. Not sure if I'm making a big deal about it. My friend has his own semi truck with a roof fan. If he's in a dry area like Arizona and leaves the window cracked with the fan on the truck fills up with dust. I haven't been out at all since I finished my cargo trailer. Still trying to quit my job and retire. Thanks for the tips.

Driving they would be closed. I'm worried when I'm camping like in Quartzsite and the wind is blowing or other vehicles driving by kicking up the dust.

You could always do a Salem Vent - open it when you want ventilation, close it when you don't

Ooooo, that's a nice vent. I looked it up. It's $0.00 with free shipping!!

I see them on most new toyhaulers. I just linked the first listing that popped up. Dug a little deeper and found one... not exactly cheap but they're very good looking and high quality

Put the same vent just in plastic and it has held up great. I think i paid 30$ on ebay or amazon. And yes a small piece of filter would work no problem

Go to https://www.etrailer.com/dept-pg-Enclosed_Trailer_Parts-sf-Vents.aspx to find Pop-up, or "Salem" vents in steel or aluminum, for $35-45.

I had considered getting those as my side vents, but opted for another type, that I had seen on semi-trailers, when I ran a receiving department. They never showed signs of leaking, so I got them instead.

I put screen material inside the butterfly opening, and modified one, used to cover my A/C exhaust ducting. They work great, no leaks.
Also, I put reversible computer case fans on hinges to be able to swing in front of each of the two main cabin vents, in order to pull air in, or to direct air out (keeps dust out!). They can run forever on 12vdc battery power, since they draw miniscule amperage.

Thanks for all the replies. Things I've never seen or thought of doing.

Do you have a thread with pics of your trailer?

It's been forever since I have been on, but I still get "Top Discussions" emails.

I picked up a couple HEPA handheld vacuum filters from the clearance rack at Home Depot a few years ago with the intention of using them as intake filters for a trailer. A little ingenuity to get the filter mounted using the twist lock mechanism should allow easy replacement at any hardware store, and easy removal when not needed.

A quick Google search indicates that https://www.amazon.com/ZVac-Compatible-Replacement-Replaces-3-SFA115-00X/dp/B008GFP33A?ref_=bl_dp_s_web_5711721011 has them for a few bucks a piece.

I don't know that this is the best size for the job, but it may provide a rabbit hole that yields a solution.
