Yep and if you want to get really fancy, ya can put the box on stilts and put a 5th filter on the bottom!

It is setup to pull in air through the filters into the box and push it up through the top.

Just doing my part ground control 🫡

I used the box from the box fan to create a bottom to make it a bit more sturdy for moving around and ensure more air flows through the filters instead of slipping in under the filters.

It also helped making the CR Box easier. I used it as a mount point for each filter.

I duct taped the filter to the bottom piece creating a sort of hinge that let the filter lay flat outward.

I then would prop up two filters creating a corner and tape them on the inside and outside.

Then I’d do the same with the two remaining filters. Then finally tape the final two corners.

The next step i do is optional, but it made taping the fan on top easier. I created a fan shield, which is like the bottom but a big hole in the middle. Tape that on top.

Finally, place the fan on top tape it and try to seal any gaps.

Oh, that’s an interesting idea, not too much different from a swamp cooler actually so ya I think it would work.

My question is, where would be the optimal spot for the ice/icepacks:

• Inside, at the bottom
• Inside, suspended in the middle
• Inside, at the top near the fan

Ohhhhh that’s a great idea! Thanks for the suggestion!

Will all of you get out of my house?!?!

Ya, they were brand new filters from the store. I bought them along with the box fan and duct tape.

This apartment doesnt have a HVAC system (just wall mounted AC unit) so it’s doing all the air filtration.

Funny enough I cleaned that rug after first moving in (apartment was pre-furnished) and it looked clean for a whole day.

Yes it can!

I was a little miffed when i went to buy the goods for this box because i couldn’t get MERV 14 filters and had to settle for MERV 13.

I plan to make a frame so i can just slide filters in each side with the fan mounted on top. I’ll have to figure out a means to create a nice seal between the frame and filters so the air passes through instead of around.
