This is amazing!!!!!

Was watching Star Talk and learned about you from Neil. Love the videos keep them coming. Blessings to you

Love the video Brian. Keep up the great bits!!

found your videos via the top posts in the parallel view subreddit. thanks so much for the high quality work. these are amazing.

Brian, that is so awesome! You go man!

Who else can say they have done 1 million push up!

Awesome.

Beautiful

It's good that you weren't there to interfere. This is how nature is. Crows need to eat. Snakes need to eat. It may seem cruel to us humans, but some wild animals need to eat other animals to survive.

Does it remove mold

Hint.... a single filter....but 20 x 20 x 5 inch thick.....not 4x of 1' thick......offers the same filter area as the 4 thinner filters...and it's easier to attach ONE filter !!!!

His scientific research is greatly needed at this time!

I'm not skiting, but I can do this easily without the viewer...

Hi Brian, the lighthouse and Lion are so cool

Israel has lost the war. Hostages not free. Israeli society shattered.

3D print the frame for the filters n fan to rest on boom! sell them #thankmelater

1) NO! A CR Box does NOT perform better than a good HEPA air purifier. It will be able to beat some air purifiers, for sure, (esp. at filtering larger particles) as 99% of the HEPA air purifiers don't actually filter at a HEPA level. But it will NOT filter better than the upper-echelon solutions like IQAir, Airpura, etc. 2) It doesn't have any carbon so it will be less effective for chemicals/VOCs than units with a good amount of carbon. 3) It IS good for filtering larger particles. And it will help take out larger particles in the air but the smaller particles are the most dangerous to humans and the most plentiful in the air (ultrafine particles = 90% of the particles in our air and they are .1 to .003 microns in size). 4) NASA, Hospitals, Airplanes and on and on and on use HEPA filtration for superior air quality NOT MERV 12,13,14 filters... 5) The CDC recently said, "DIY air filtration units may be effective for temporary use until commercial portable air cleaners with known performance characteristics can be acquired, or used in areas that cannot obtain commercial portable air cleaners. However, the EPA does not recommend the DIY units as a permanent alternative to products of known performance (such as commercially available portable air cleaners)." 6) CR Boxes are better than nothing and they definitely do improve the quality of air in your space esp. for larger particles - but they do not filter better than the upper echelon HEPA solutions on the market.

Boycott EVERYTHING j3wish...

I thought it was merv 13 cant find merv 14 anywhere

Got rid of the first since it was pretty rude. I do feel bad what happened to the chicks, least you got to spend some time seeing them grow up however.

大事に育てていたのに😢可哀想ね

Science needs MORE than a teaspoon of sugar to help the medicine go down :)

What large egos to name taping filters together after yourself....what a fragile ego 😅😅😅

Al Gore invented the internet 😂😂

What people don't know about air filters is that even the best will only filter out less than 10% of the particles in air. Over 90% of the particles in the air are "ultra fine" particles in the range of 0.1 microns to 0.003 microns and even smaller, and these are the ones that can do the most harm to us, being small enough to enter our blood stream. The fact is an air filter that can filter out these ultra-fine particles has not even been invented yet. All these air filter technologies we have today are historically centered around removing "dust" particles.

So sad,nature or not it's devastating and a painful way to go...Animals,though,have no moral agency-they are wired only to survive and reproduce,and some birds help insect control,etc

No le gustas las palomas ..

Traduzcan al español!!!

Of course these work, the've been used for decades. These DIY filter boxes just didn't have a fancy name till recently.

Such a good mom

Thats so 😢😢😢😢😢

Hello!!!! 😀👍🏼

Excellent interviews and coverage of the Lindau meeting . Seems like old times as the participants are at ease after the pandemic . Safe journeys to all.

Hi Brian!!!!

Yannai is excellent

i'm so sorry, this just happened to me as well. 😞

Elton John recommends gargling vinegar and honey . Advice he recieved from fellow pianist Leon Russell. Have a great conference.
