Mixed results reported with furnace filters. Don't leave it open all the time the size of furnace filter. You want to be able to close it off too, as the fine playa dust will blow right through a filter, and way more so in a heavy wind.
For the swamp cooler, remember you only need (but do need) a small exhaust hear the top to let the warm/moist air be forced out as your fan brings cool/moist air in from the swamp cooler. Consider that it should be the same size as the duct? While the fan is running, it will create a positive pressure within your shelter, helping to keep dust out too.

Perhaps a nylon strap, all the way around the two sheets and across the ground to the other side (make the triangle shape), one at the front, one at the back and one at the middle, would stop the bottom of the sheet from spreading apart, and hold the structure together. You may even be able to have a scrap of nylon strap sewn to the strap at the ground at each side with a grommet for a tent peg of your choice. All you'd need would be a way to prevent the wind from blowing the bottoms of the sheets inward. If you weren't shy of space/weight, you could table-saw an 8' 2x3" with a grove for the bottom of the sheet to sit in...

How about combine these two ideas and fasten the nylon strap to the walls so they hold the walls both open and closed?
Canoe wrote:Too complicated.
It's two sheets, edges taped with 3" foil tape (moop, skin, breathing), taped/hinged along the top.
Nylon strap (don't need tubular; 3" flat readily available), 8' for the sides plus the distance you want the bottoms to be apart (4' ?), plus 3" to 4" for overlap for sewing it into a loop. Make two.
When the sheets are unfolded/opened within the loop, they'll only open so far.
Nylon strap Tabs with grommets, sewn to loop on each side (use a 3" to 4" overlap), close to but not quite at ground, so when they're pegged to the playa they tension the loop to the ground.
The pegged loop over the top prevents it from closing.

Jared It used 2" polyiso panels painted white.
I discovered that one person's body heat was sufficient to heat a closed H2 to an uncomfortable level. The swamp cooler I had was insufficient for cooling the H2 in the middle of the afternoon and the furnace filter duct didn't seem to increase airflow very much. My typical use was to prop the door vertical while sleeping at night to provide airflow and open the door all the way once the sun rose in the morning. I was able to sleep comfortably until approximately 10:30AM. I wasn't inside the H2 during any dust storms, but wind never blew the door in and very little dust ended up inside.
Canoe wrote:White paint absorbs a lot more heat than the shiny foil. Why paint the shiny foil that reflects sunlight and heat away?
Canoe wrote:I can see your swamp cooler in one of the photos. Given the much larger spaces that swamp coolers cool, and you reporting it wasn't up to the job, I'm very curious to know how your swamp cooler was constructed?
Jared wrote:I couldn't find the foil polyiso panels in my mid-sized Canadian town. Apparently they're not used very much as a building product outside the US. The only ones I could find were primed with a thin layer of white paint and I figured painting them was easier than gluing foil to them, although I may have been wrong. The research I've done suggests that the different between white and foil is not as big as you suggest?
It was basically a hybrid between Figjam's bucket and box designs. It turns out that there is a lot of nuance in Figjam's designs that you lose when you fuck with them. Next year I'll just make a bucket.

You can burnish it to a fairly reflective sheen, even after it is dirty. I use a paper towel for that.I brush it on, but it can be sprayed.
