Cutename
trendless@Cutename nope! Some really good ones using 2 filters lately. But filters can be all sizes – both length/width and thickness – wanna have as much filtration area as you can in the footprint you want.
@trendless We're trying to build as many as we can on a limited budget. We're looking to protect a lot of people for just a few days. Any recommendations are greatly welcome. It's about 80k sq ft of assorted hotel function space total.
@Cutename can you take your time to find the best, cheapest stuff or is there a tight deadline?
@trendless Definitely on a timeline. We may have a resource for wholesale.
I've been eyeballing the two filter style, forming a triangle base for stability and safety.

@Cutename I'd be tempted to look at single 5" filter units. Perhaps the quickest to assemble and mayyyybe competitive on price. Should have similar throughput to 4x1" filter cubes. Triangle is maybe good too, especially if 2x2" filters. Definitely get good, vetted filters tho; some real stinkers out there. Apologies if any of this is stuff you already know.
@trendless The deal is we have a bunch of box fans and a next to nothing budget. 4 + filter designs are going to leave us with more spaces without. I'm trying to find our best compromise. It's not a fun place to be.
@Cutename maybe it comes down to as many fans with even a single filter as you can. Spread it out as much as possible.

@trendless @Cutename There is on paper that indicates that the single filter taped to the box fan is almost as effective as the four. My experience is that the single filter gets dirty much faster. I cut free and tape on new filters every month. For something like a week long event, that would not be a detractor?
@trendless @HaplogroupNews THANK YOU! That's exactly what I expected. We're running them for 5 days. We're good! I just need to consider keeping them from being knocked over in certain locations. You rock!
@Cutename @trendless As you will have the boxes mostly intact with the single fan method, you can use it to make extended supports on the sides.
@HaplogroupNews @trendless The CR boxes have to survive being kicked, tripped over, and transported from room to room occasionally. They're going to take some abuse. I'm planning to reinforce with cable ties, but we've got to have a stable design. Something about having a safety device causing injury just seems off.
I also get to figure out how to make them visible in a darkened room. I have fun ideas.

@HaplogroupNews @trendless I know we have regular caution tape. I'm hoping for actual lights. I want two or three of them to be VISIBLE, and hopefully a bit geeky and fun.
Folks will likely be in costume / cosplay, so we've got to be a bit extra here, at least for the dark spaces. I may have some geeky ideas for illumination that fit our safety requirements.
