Making a Full Face HEPA Respirator 

Sir, i have to say this is outstanding craftmanship. In my language, dude, you are too good.

Dude! It was truly amazing what some of us did during the lockdown and you sir...that’s some next level awesomeness indeed!! Surprised/disappointed this vid doesn’t have waaay more views! crafted quite a few hepa filter designs but childs play in comparison! It's insane how we collectively dealt with the lack/shortage of N95's/masks in general. Anyway, thanks for the video and I hope you and yours are happy and healthy!🤘🔥🤘

love it. all these parts are so inexpensive, but because 2020 you put them together and it's like: here's your $1500 respirator!😂

I love watching artisans at work. Too cool!!

you deserve more subs man, great work

This is what i've been looking for!

Oh!! so close to what I designed. But so different. Good job on vacuum forming thing. I think you scaled it for your kids face :)

Not every body has the fancy equipment like you!!

One word from Evil Dead 2: Groovy!

That takes The Snorkels into a whole different direction hahahahaha :D Cool!

Omg Morgan I love it! Lol

For the visor fog there is something that motorcycle shops sell called catcrap which you can wipe on the inside which will stop that. I use it on my visor for my motorcycle.

Hey, how and where do I find the plastic tha you use to make the mask.? I have been wanting a clear mask for a while can't find one.

is the air flow nice in the face mask? how big is computer fan you use? what kind of filter that you use?

Your are very creative. I would follow Alec Boss's advice. The "problem" with Hepa filters is that some, not all, are made with fiberglass. If you cut the HEPA bags or filters, you potentially will introduce loose fiberglass into your filter system which may cause issues with you lungs down the line. We are treading new territory here and no one has done any real testing on cut fiberglass filters and possible introduction of loose fiberglass. Just erring on the safe side with this information. I'm not an expert on fiberglass filters or the affects that cutting these filters have or their integrity after they have been cut.

the air flow from the fan and air come out in front?

So cool I wish I had a 3D Printer

soo, how did you attach the silicone to the plastic? What glue did you use?

Excellent mask

I'm curious about how well you could be understood if you were talking and would the seal be affected. Could you be understood? Also I think if you made the small filters on the mask about 4 times that size you would not need the fan. Final thought: If you cut a 2 liter bottle on the diagonal wouldn't you get a similar mask shape without vacuum forming?

Very nice! May I ask? Why did you put a filter on the end of the fan outlet? And how do I know what fans work on a battery like you used? Liked and subbed!!

I want to praise you for the creativity and the dedication but this mask is *ineffective*. First, look at 3:53, you have filters that are supposed to filters particulate of size down 0.3 micron but then leave a gap of 1-2mm , you need more silicone and more pressure , there is a reason why if you use real respirators all day it does shows on your skin. Plus as other said beard is a no no. Second, the fan is useless : it fogs up because when we breath out we emit water vapour , just creating a small positive pressure won't help as the water vapour will start accumulating as it get partially blocked by the filters that soak up and will become a bacteria breeding ground plus quite hard to breath . That's why you have one way pressure valves in respirators, between filters and mask to not contaminate the filters and get soggy from your breath and one valve between the mask inside of the mask to the outside to discharge water vapours that doesn't have filters because it's not needed : the positive pressure built inside the mask when you breathe out that doesn't let the air outside in before the valve closes again. In your final setup you get less fog because there is simply no seal around What you need : A big surface , multilayered HEPA filter in a cartridge , ( not the one used for vacuum filters , get a H14 rating or better) , remember more surface = less breathing strain, then an one way valve of the size of a 50c coin in front of the mouth , and a better contouring , meaty silicone seal . Plus if you go for a full face mask a one point elastic band is insufficient you need at least 2 . Anyway keep up the good work.

I HAVE A CANISTER DESIGN THAT I WANT TO GET TESTED. It is the exact same, but uses a two to three compartment part wet filter.The first section is contained in the same manner as the activated charcoal, and is simply a wet rag stuffed into the front of the filter. The second section is just a dry cloth or sand filter, that can be made using straws (filed with sand and contained using cotton stuffing,) or a second section inside the canister. (possibly a second soda that has been cut in half or a third. Sand is used to absorb excess water from the filter and then dry quickly. Cotton may work just as well to stop water, but is more easily contaminated. You can use a candle wick style water feeder to keep the filter wet, which can be made using a piece of rope, and pill bottle. you drill a hole in the top of the pill bottle, super glue the lid to the bottom of your canister, and then run the rope threw the hole. the filter will then be fed using osmosis, which will only fill the filter with water as it dries out. Came up with this idea for covid. If you used this you would need to replace the or wash the cloth part of the filter on a regular basis.

Tu los haces? En cuanto salen y de qye país eres?

Fantastic design but doesn't true HEPA filter contain fiberglass particles? Wouldn't want to breathe those. Do you think the cotton layer is enough to keep fiberglass out?

can virus come inside body trough ears ?

Nice idea but ... it doesn't work this way. Please read a little bit more about filtration, volumes, air flow, surfaces, materials...etc. this kind of thinks. I was glad to see the beginning but the shape is not quite right and the filtration system... hm, no. The beard is a big problem anyway, in a refinery like Exxon you will be not allowed inside the plant, in case of event (gas leak) the survive mask will not fit to your face... you get the idea. Biohazard is even worse. Try, if you have the skills (and the head) anyway something like a semi-motorcycle style head cover and hip ventilator with proper filter (surface, HEPA H14 or up to E or U...etc). High filtration require some effort, some ventilators are like a drone motor or small vacuum cleaner for table...you get the point; a PC fan will not do the job, is to weak... Keep the good work !!! Keep trying !!! Respect.

Awesome

that is so cool

its cool!!! thx for idea

So cool! :-)

Cool gas mask And also to avoid fog add an exhale valve

Awesome...👍🏼👍🏼

FUCKING GENIUS

Such a nice job. Just print something to avoid those metal pins you used to hold the elastic...

thats all very well and good providing one has a 3 d printer , not every one has one

My question is would it be better to have a mud face like women do when they go to a salon

No one mistake not every one has small short nose or same porportion of head and mouth size thats y respiratory n95 is perfect for everyone.

I was looking for a video to make an easy mask at home to protect myself and others from catching the Corona virus, not a way of complicating life and not accomplishing the original goal. There are real problems in the world now because of the Corona virus, and if you put your mind to it, could you please make a video on how EASILY make a mask that can be washed and that protects people from catching the Corona virus?

I'm impressed. lol

Couldn't you purchase a universal gasket?

For the fog, use liquid soap.

Cool! Now all I need to build it is everything in the video...which I don't have.

That’s awesome man and I would even submit the designs to some of the larger companies out there that are being outsourced to help in the PPE shortage like Otterbox etc especially your other design which is easier to make. One thing I might suggest is using Filtrete Furnace filters by 3M that have a 1900 rating or are 13 MERV or higher. These filters are designed to filter down to .03 microns and most are made of polypropylene and polyolefin which are non toxic unlike fiberglass although you’ll still deal with some fuzz. I do like the HEPA idea with the cotton to protect from the fibers because you’re getting double the protection. Either way great job man.

Isn't that tube too small? Even with a military/industrial mask that uses 40mm thread/tubes is hard to breathe under phisical activities, I can't imagine that mask being viable for normal day activities...

Hi, I'm from México, I love you're proyect. I wan to congrats for these proyect, you try to hel people, it's amazing what you are doing. Lol, Lol, lol😍😍😍 Could you tell me what kind of líquid silicon use for seal it, the Brand, because here don't find something like that. Not the window silicon, the líquid, Please, We make the mask, just have problems to continue. Please, help us🙏🏻🙏🏻🙏🏻🙏🏻 and thanks again😘

That first look :)) I think the video is very useful. I would do it in a different way but who cares :)

There are vacuum bags which are containing antibacterial substances between two layers, if you cut the bag, they can come out and they can be harmful to health....

I would pay you $200 if you could make the D MASK. I found a version that looked like a D MASK not made for scuba and had a filter at the top. Everything was slender and hi tech looking.

I think the weakest link should be the 3d printed part.

Instructions for the Common Joe.

seedy!!!!

Looks cool. Won't the positive pressure of the fan keep the breather valves open when inhaling, unless you inhale at higher pressure than the damn puts out?🤔 Other than that, it looks awesome.

use mi portable air compressor instead of Fan

Beautiful, but not enough filter media to not leave you hypoxic.

still fog at the end

Steven Spielberg production

Bad ass, LOL

your kid should wear a dust mask too

Fog its still there 😅

Aww maybe the anti-fogging mechanism is overly elaborate? A better design imo is to build a check-valve system where exhaled air is channeled to a separate exhaust port _without_ using battery power. A passive solution, in other words. Take a look at this guy's idea: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Y0jYmJzEIuw.html Best one yet I've seen so far.

Ok vallamos todos a comprar una impresora 3D Para hacer los aditamentos accesorios ... La idea es muy buena pero desearía que lo pongas ha ras de gente que no tiene recursos ....

You could have just craft a nose cup without getting a fan on your head lol

One issue I see.. the high percentage of people that wear glasses.

Something tells me that you have a lot of time on your hands

FIRST REMOVE THE BEARD LOL

Will never seal correctly with a beard

You're a nutter very good now for a space alien have a really good week don't forget to wash your hands😊🤣🤣🤣😂👍

Uh NOT, , WAY TOO MUCH WORK FOR THIS SENIOR, LOL😂😂😂

LOL, LOL, LOL....

I cant recommend this video. Why? Because you have Facial Hair. The whole point is to crreate a seal between the mask and skin. The hair prevents a tight seal. Thats why Firefighters are MANDATED by law to shave..Everyday. Not even stubble. Because No matter how well the mask is produced, if air can get through the maask and skin, the mask is pointless. Another reeason to have a clean shaven face, like ALL Actors did during the Golden age of Hollywood. Beards, Facial hair became popular in the 60's. Need I say more?
