- Air curtain technology created by a U-M startup, Taza Aya, can attach to the brim of a hard hat and deflect 99.8% of aerosols from reaching a worker’s face, potentially offering a new protection option for workers in industries where respiratory disease transmission is a concern. Independent, third-party testing of the device showed the effectiveness of a downward-flowing air curtain, curved to encircle the face, coming from nozzles at the hat’s brim a few inches from the face. That curtain is just one part of the device’s defense against pathogens.
"Our air curtain technology is precisely designed to protect wearers from airborne infectious pathogens, using treated air as a barrier in which any pathogens present have been inactivated so that they are no longer able to infect you if you breathe them in," said Herek Clack, a U-M associate professor of civil and environmental engineering, and a Taza Aya co-founder. "It's virtually unheard of-our level of protection against airborne germs, especially when combined with the improved ergonomics it also provides."

A wearable laminar flow hood, kinda interesting
This isn't laminar flow.
If it helps to reduce infections, why not, good job.
Really revolutionary! That's thinking out of the box and into the curtain!
Are there any Ozone Exposure (or generation from large amounts of staff using them in an enclosed space) issues with the Plasma?
Also what is the pros/cons vs a PAPR system?
Ozone is the most important issues with this kind of equipment same for air purifiers that has uv function
@@exosproudmamabear558 mechanical filters don't make ozone.
There's no ozone concern with respirators.
@@ggad1899 specifically the “cold plasma” (if done using air, not pure nitrogen or argon etc) generates ozone and other reactive bits that cause it to work if i remember correctly.
Not HORRIBLE, but i want to see if/how it was taken into account.
Works for stores and freezers- this is very, very good work!! Cheapskate me is going to try this!
Pretty cool technology, but it does look like it takes 20 pounds of gear worth thousands of dollars to replace a 9 gram, $1 filtering facepiece respirator.
I'd be interesed in seeing detailed simulated workplace protection factor scores taken while moving or with cross breezes. An unshielded air curtain seems vulnerable to entrainment. But it is impressive how well it reportedly works.
I'd be interested if the air curtain design can work with existing 8 CFM PAPR blowers, or, if not, what the blower requirements are.
Currently I use a 3M versaflow .
Iam Immunocompromised..
This would be interesting to see how it works as a replacement in due time..!
@@Peterthethinker
It does seem like this could be especially useful if it could be retrofitted to existing investments in equipment.
I'm still really interested in seeing test results that are representative of real world use as worn, while moving. Or doing tasks that one might need to take a respirator off for, which would include medical appointments, and eating in contaminated environments (where hopefully eating food that's exposed to that in contaminated air won't be infectious).
Very exciting! Though, I wonder about the venturi effect - where the flow of air draws surrounding air in. I'd add a low pressure air source for the venturi effect, so contaminated air isn't what's drawn in.
I'm also curious about the noise, especially through the ribbed, flexible tubing. High pressure air of any kind can be very noisy.
I think depending on the flow rate, those Eddys would/could be forming below the chin and away from the nose and mouth, making that less of an issue.
What happens when someone sneezes? What about high speed aerosol sprays (like from a toilet)?
Solutions , very well done.
Been recently thinking about this for the garbage company. They may not have to lift bins anymore which is good, but the air quality can be terrible and especially in the summer time.
So many more uses than working in hazardous atmospheres.
@@Travlinmo What other uses?
There is no information about the battery life of the mask. I assume it can only operate by battery, but have no idea how long it lasts with each charge
Depending how much space the plasma treatment takes: They can put a fairly large battery in the backpack shown at 1:00
No word on weight or maximum flow rate for breathing though.
Would not trust this for cycling. N95 masks work surprisingly well for cycling (due to the large surface area) as long as the temperature is far enough from the dew point (can't breathe when condensate clogs the pores).
This is crazy cool! I really want to see this get bigger and more mainstream!! Good luck
This is amazing! It's especially Important for poultry and dairy workers as avian influenza is trying reeeeeeaaaaallllly had to make the jump to human-to-human spread.
What an extravagant service to replace a simple wearable filter. How many thousands does it cost, how heavy is it, how long can it run on its charge, and if the person wearing it coughs or sneezes will the air curtain protect the people on the other side?
Way too frickin cool, what would the cost be to the customer?
I love good innovation but i wonder about "dry eye". I'd have to try it myself! 😊
Interesting! Wouldn't adding a clear plastic face shield make it even more effective?
Yes. But those already exist commercially, called loose fitting powered air purifying respirators, such as the 3M TR 300 with a soft head top.
This has slightly reduced compared to a PAPR soft top, but, I suspect, less robust protection.
Awesome!!!! Is the plasma safe?
Won't help with droplets, which are a major transmission route in the dairy industry, normwith people,touching their faces. And as far as adoption among the public, if you're not gonna wear a little mask to protect yourself, who is going to wear a helmet connected to a backpack to go out to eat?
I bet the cosplay community could make this thing look ridiculously cool!
It actually would help with air droplets, if it's strong enough. But yeah, it's a whole backpack-helmet solution instead of a small face mask.
An interesting and valid statement concerning the limitations to effective communication when wearing a mask…
Nobody likes to be misunderstood…
Amazing and very creative!!!
As a former paramedic constantly exposed to TSS (Toxic Sock Syndrome), I approve this message.
How loud? How heavy? How much charge? How expensive?
This sounds great for the turkey processing facility and some other places. It doesn’t seem practical for everyone to use because it must be expensive.
need that for when I am eating it from the back
As a nurse I used to wear something very similar. But with a face shield. It was of a higher efficiency than even this.
Anyone watching this should realize it’s ineffectiveness to eat or drink. The particulate would still get on your food and in your drink.
Nice, in hazardous environments this is awesome!
Thank you 🙏 well done 👍 I am hoping it will be in store 🏬 soon at least at doctors 🥼 office 💡👏👏👏👋☮️
Perhaps it could be used in Surgery, in some form to help surgical team staying safe..
At 2:30 it looks like the air intake from speaking was pulling some of the vapor through the air curtain. Has this been examined in the lab testing?
Ghost busted them germs bruh. Cool.
ON a nother note this be cool for hologram masks. Wait could you use this quarenteen rooms and some public places? idk
Very cool
Can we use this for painting application...?
Great work!! I want one
Just a fancy polished Cyberpunk skin mod
No mention of how often you have to buy plasma. Battery time. Please advise.
Hard to believe, but if it works it would be a great idea
Company in South Africa have already invented this.
$how much?
I wonder how noisy it is, blowing fan even 6h a day on my head could get me headache
with that kind of airflow probably not much worse than a personal computer
@@markifi yea but some pc can be loud as hell and others as quiet as fly, still with that kind of curtain of flowing air can be noisy, and they did not demonstrate a noise level of this thing
Plasma gas can burn lungs we have these problems in the welding process
How do you kill that which is not alive?
However does it protect other people from you? This is the real point of cheap paper masks. That's the other question you're talking penny is the use and a lightweight easy to distribute compare it to one of these portable air curtains. How much do they cost? The idea is extremely promising and certainly has its place.
Super cool!
How effective is it the way they kept showing it, with the intake/moror UNDER the closed jacket? Because it's extremely unlikely their tests were done with the intake vents completely covered. 🤦♀️
Also no information about the effects of wind gusts, and air coming from the back and sides, and how and if these disrupted the air curtain. No info given here about any testing in extreme heat, cold, very high or low humidity, and the effects from those environmental conditions, either.
Plus, is this like a PAPR, which doesn't filter the user's exhalations? "Protect only me not thee" is a horrible option when it comes to the Public Health side of PPE.
Don't forget, you have to either have very short hair OR bundle it into a bun under that hard hat style helmet, too - the latter is discomfort and annoyance that discourages use and probably wasn't considered as affecting use.
I'll keep wearing my P100 filter elastomeric respirator (mask).
Just wear a mask🤣😂🤣
Amen,🙏
Honestly, design should focus on the nostrils, mouth, and EARS!!! A steamless goggle w/ an earpiece like microphone used by sports commentators would be a nice start. But I would say something positive, if nothing else, incorporating this to a Hazmat Suit scenario for front line people would be nice to protect them against pathogens...esp during plague breakouts in Africa....
maybe you arent aware. hazmat suit usually uses a SCBA....this thing would be totally pointless. like strapping a motor onto the top of your already working car.
😍😘
0:42 Fuck the ‘mask’.
Let’s talk about how the birds are kept. And why. And what for.
Isnt it obvious? Probably neutralized with a sedative,caged and later cut up for food.
Another tool in our pandemic toolbox. Because we know there will be another pandemic sometime in the future. And if the next one is deadly enough, anyone with half a brain will be looking for solutions to protect themselves (no matter how it looks).
Something else that's needed: a way to create protected spaces in small public venues like restaurants, pubs, etc. And classrooms, office cubicles, reception areas, etc. I saw some creative attempts with upgraded HVAC systems that included UV-C irradiation during the Covid Pandemic, but most venues did not have the funding to do much of anything. They just saw traffic dwindle to almost nothing, and, when possible, went to curbside pickup, home delivery, or other temporary measures.
Another global lockdown in the near future sounds catastrophic. We need some very creative & effective tech that can keep humanity up & running...
This is a beautiful idea! I appreciate your work. But that turkey place..... how horrible! Those birds can't even stand and are pressed in those cages horribly, no wonder they worry about diseases........ I would never raise an animal like that!
God said he would pour out his knowledge to the people toward the end. Thank you.
You will never get me wearing anything on my face ever!
Ok cool
Great idea, but the argument that people would 'go out to eat or drink' while wearing a hard hat and an air flow machine is absurd. Just fucking wear a mask. It's not that hard, children can do it.
You have to take the mask off to eat, You don't have to take this off to eat.
@@bunnypeopleWhich is why you eat on the patio. I do it exclusively. Works great.
