congratulations.

tis is fantastic.

This is very interesting.

As someone who’s not seen this before, cool, will be keeping this in the storage locker I call a brain. It’s very telling however each time he refers to the box as the “C&R” box instead of just “the box” while going* through the steps. You’re already the Dean of a college brother, you ain’t gotta be extra.

SCIENCE!

Maybe because he is using tape that off gasses(voc's); use a hot glue gun.

Why is he wearing a mask?

These egotistical tools naming this like they just discovered string theory. It's a box glued to a fan... Tell me you're insecure about your accomplishments without telling me!

Next I'll name a rubberband around a deck of cards some pretentious Italian name after me!

Hard to take a guy wearing a mask seriously

Video didn't age well..

I love that 90pc of the comments are hating on the name. It's indeed cringe AF to name that thing after yourself, it's almost like making warm water after yourself. Brought to you by Brawndo. It's got electrolytes.

Put one filter on the back of the fan and have a descent air filter easy squeezzie! And "That your dinner .

Reporting all the errors in the data set is going to land me an A for my capstone. Thanks for the A.

I work with Molly!!

S4A sent me here, and I'm quite happy he did <3 Thank you so much for showing me this!

I'm looking at an MCAS diagnosis and thank god I found this

65$ if you live in america... The box fan alone is nearly 70 euros The filters are nearly 100 euros The entire thing costs as much as a brand new air purifier.

There's a lot of Chinese nationals on that campus, what are they doing there?

I appreciate the demo, but .....the face diaper is RIDICULOUS!!!

Lol this has been in amateur KZbin DIY channels for years to reduce air pollution on the cheap. The name of this box sounds like I need a degree in rocket science to build something a 3rd grader could do DIY. Try to accomplish something real instead of sticking your name on a cheap life hack.

Question: an I use an exhaust fan instead of the regular one? Is there a way to box the filters so the dust is not exposed at sight. Yes, the fan will attract air and expulse it on top but the filters are retaining the dust that will. OST likely fall out when I stop the fan. I think .. am I wrong?

Why are you wearing a suit and tie... in a shop video? ;>)

Thanks for this

As a nearly-graduated CS student at Portland State, I mourn the fact that I just barely missed the opportunity to take a course with Professor Mitchell. Melanie’s voice is refreshingly honest and level-headed in our current world of AI hysteria.

Everyone is like "i made this in 200bc with my great grand uncle sextuple removed". did you advocate for air quality for 20 years? Did you do research to show its effectiveness versus hepa filters? Did you show its effectiveness for removing viral particles in different room sizes? I didnt think so.

What would the difference be when the fan sucks in the air and air would be filtered out?

So how do you dispose of these when they are full?

Does this remove mold?

Simple method to get 97% or more of the results. Take your fan and one merv 13 filter. Turn the fan on and simply place the filter on the back of the fan. Air pressure will hold the filter in place until you turn the fan off. Requires no tape and takes only 15 seconds to set up. In short order most of the room's air will have been filtered as the air runs through the filter several times over and over. Do not worry about a few molecules escaping the first minute of use. When the filter needs changing, simply repeat the process. No need to replace 4 filters each time. Its called the Cheap-Skate Box. No professors or Phds were harmed in this process. (Optional use of N-95 mask during the early minutes while the room's air is filtered several times.)

Wearing a mask like that while building your filter is ridiculous.

Saved my life!

wood working environments. Thank you

Isn't this called Comparetto Cube instead ? kzbin.info/www/bejne/l6ial4iDnbOirJo @4:23

He's using painter's tape, not duct tape, fyi.

I made a modified version of this using 4 box fans for the walls and a 5th box fan for the top.

High quality filters are way too expensive to be using 4 at a time. I just buy 1 good quality filter and slap it on the back on the fan and call it done.

Thank you for this clear and helpful tutorial.

Why is this guy wearing a mask?

Just finished ‘Artificial Intelligence for Thinking Humans’. Melanie Mitchell is amazing

Practical

Thank you, it works like a charm

See video How to Make a Better DIY Air Purifier by Healthy Home Guide

Looks great until you have to change the filters. 😒

3M gonna announce Professor Corsi unfortunately suicided himself if he’s not careful

Thank you, Dr. C! ⭐️⭐️⭐️⭐️⭐️

can you use the sides of the box to create a circular shroud on the inside of the fan? that way the box is completely used. back panel for the bottom, front panel for the top (with circular hole cut out in the diameter of the fan blades), and hten the remaining thin edges would be used to create the circular shroud.

Please note in putting the box together he had one edge on inside and opposite edge one the outside. if you do this with all four you'll have a square instead of a rectangle. wasn't sure why that wasn't made clear and yeah, i know, most of us would say well that's obvious... but this is the internet after all.... also my guess is by putting those triangle corners you've lifted the fan enough that you've probably created about as much space as you remedied. so you could just make sure it's well taped?

You know, I want to ask if he knows the type of bearing the fan uses, a sleeve bearing or ball, because placing the fan like that with a sleeve bearing could cause it to go out pretty quick. Then I looked at the channel's name and think maybe that's a stupid question to ask a literal engineering professor.

Great video! This comment section is fucking awful though
