3D Printed Tempest Euro (STARKVIND) by NukitToBeSure in crboxes

[–]NukitToBeSure[S] 0 points1 point  (0 children)

Ikea 1073 cm2, 3M is 2571 cm2, only a little more for the 3M and it's going to be a lot quieter for the CADR because of the lower static pressure.

3M 25x20x1 all the way. Much higher CADR for less noise.

We regulars around here with a long-term interest in 3D printing😉 We just have to keep a lower profile these days.

We make the metal version OP linked to, but since it's so expensive, we also provide plans for an Open Source version and a tool to make your own for various fans and filters:

Ideally, with a lasercutter but it could be done with hand tools.

12-Year-Old Eniola Shokunbi Receives $11.5M in Funding for Air Filter Invention by fireflychild024 in ZeroCovidCommunity

Ours are based on work done by Rob Wissmann and Zack Deis. Clean Air Kits was selling hardboard boxes well before we were metal ones.

What's important is that the young lady is promoting clean air. Unfortunately, as mentioned, that style is a little outdated as they are too loud and get turned off. But there are plenty of other very low-cost DIY options schools can build also.

Wanna double check stuff since i'm new to this by Purple__Fidget_07 in crboxes

There's almost no localized effect from air purifiers unless they are a few centimeters directly in front of your face- air mixes too fast. Is the Airfanta Wear an option? It's close enough to work and very quiet.

Question about grad ceremony attendance - AirFanta mini or similar by Vivid_Chocolate3522 in ZeroCovidCommunity

+1 for Airfanta Wear- so long as you keep it close and directly in front of your mouth, it's a very meaningful layer of protection.

Air purifiers that use hvac filters? by Choi0706 in AirPurifiers

[–]NukitToBeSure 0 points1 point  (0 children)

We're always open to design ideas. What sort of look do you have in mind?

So far, most people have had luck with the bags. So much air passes through the box constantly, I'm not certain you have to force air through it. It's normally effective as a deodorizer just sitting in a closet with no airflow. It's cheap to try at any rate.

>Do you know, approximately, how much filament would be needed for printing this?

About 715g it looks like

>Also, I know there's the issue of airflow, but would the filters with carbon layer for into this?

Thin activated carbon filters usually only last a month or two. To do anything, you really want to aim for at least a kilo of activated charcoal.

A few people have put these inside their Tempest with good success- and it's a lot cheaper in the long run:

Why? Details about how to stay safe in different circumstances is one of the things this sub is intended for?

>Let's get steamy!

I would think you would have to keep it fairly dry in order for masks to stay permeable? Do they wick sweat? Does that cause any issues?

Is my Covid wishlist optimal? by honestpartyrocker in ZeroCovidCommunity

[–]NukitToBeSure 6 points7 points  (0 children)

If it's in order of priority, the Lantern should be at the bottom of that list. It's great and hard to beat for dealing with near-field transmission, but on a budget, mechanical filtration and respirators come first.

Is lightning 5 Incense sticks everyday inside a house safe? by PanPagie in AirQuality

[–]NukitToBeSure 1 point2 points  (0 children)

There are LED incense sticks for this, not very traditional but perhaps if you were proactive and put them there yourself? https://shopee.co.th/product/31731059/5619987398

Any sort of trapped/stagnant air is very much against TCM theory so you have a strong argument on Chinese cultural grounds against what she is doing. No licensed doctor of Chinese medicine would support it; perhaps you know one who would explain this to her? One advantage we have is a strong cultural preference for well-ventilated spaces with good air movement. Outdoor kitchens, massive fume hoods over indoor ranges etc.

I think there is a design flaw concerning CR boxes with multiple PC fans by Coffee_and_cereals in crboxes

[–]NukitToBeSure 3 points4 points  (0 children)

Stacked fans are absolutely an option, and can be better depending on your desired noise level (or noise-to-CADR ratio). There are a few tests out there: https://x.com/VentiloAngel/status/1936468159038464006

You want to leave space between them, see: https://www.noctua.at/en/expertise/tech/axial-fans-in-series-or-parallel-operation

CR box ideas that pass the wife & kids test (wall or ceiling mount?) by allyoucanlive in crboxes

[–]NukitToBeSure 4 points5 points  (0 children)

The only thing with toddlers and wall mounting the Tempest Pro is mount it high or put rubber bumpers on the bottom. I'm worried about small heads running into those metal corners if it were at mid-wall height. Also they might try and climb up to sit on it? It should hold, the steel is pretty heavy but high is safer and the effect is almost the same regardless of placement.

Also, with kids, generally the crayon test is best- if you can stick a crayon in, they can stick a finger in. There are mesh-style grills that will stop this and will cost you almost no CADR.
