!!NEW!! DIY Powered Air Purifying Respirator (PAPR) for Grinding and welding 

this is bloody amazing!!!

It's criminal that PAPR isn't as cheap as low end power tools. This video is way under watched. Bravo!

I don't know how many times I've watched these and been envious. Bit the bullet and my cheep ass spent 100 bucks. Gonna try 3m cartridges since I get them free.

When the wife asked me to look at the vacuum because it wasn't picking up, I already knew what the problem was (as I nipped into the shed to retrieve the hose) ;-) Fantastic idea Joshua!

Thankyou for your out of the box thinking, I too have used powered respirators at previous employment and the work phenomenally, I have been wanting to get one for myself but have been discouraged by the cost, thankyou for this fantastic solution

Thanks Joshua De Lisle. I am new to your site, and spent about 4 hours last night up until 2am French time watching you videos beginning with the pneumatic air hammer. Your skills are impressive as well as your ability to demonstrate and explain your projects. Thanks again and take care.

This was great! Using glasses under the mask for welding might be an issue - but a diy PAPR is definately the future for this boy! No more fogging glasses, no more uncomfortable masks leaking. There are a few 3D print PAPR efforts around. Strangely none have really standardized and taken off. Should be a prime project for 3D printing.

I built this! It works great, and I love wearing it around the garage just for the novelty.

The most useful video I may have seen on you tube yet! And this is honestly mind blowing how simple the design is!!! Amazing job!

Bro you walk in that store like you were a space man 😆

Made it! Thanks for doing this video, Josh. I love your videos and am so grateful that you share your experiences. Cheers!

Thank you Sir, for the build and the inspiration. The build looks very well done and I love your problem solving skills demonstrated in the creation of this unit. Keep up the great work.

I saw this yesterday, and all my parts arrived today. I'm substituting a cheap, full face respirator for the snorkel, and 3D printed a 40mm to CPAP adaptor to connect the mask to your pump design via the suggested CPAP tube. I can wear my glasses, since the seal doesn't matter with the positive pressure. 👍🏾

I have received a great idea from this video. Instead of spending a butt load on insulation for my garage I should build a shed for welding.

Very well done! Particular thanks for the detailed component list! Love the addition of variable speed.Sometimes, LESS is MORE!

You are a absolute legend!!!!! I’m going to start building mine this week. Thanks mate!

Haha I actually made this, using it in MIG workshop 8 hours a day the QA PAC tested it as I used a S10 carbon filter from the issue gas masks I had spare. Rotated the battery mount so was more horizontal and inline with the pump housing and tig welded a twist notch cap for the filter so looks like a complete unit. Lovely base idea mate!!!

I would put the filter just before the tube. Less chance for leaking in. Every connection and the case of the pump can leak air.

Excellent, very well done! The 3M was to be my next purchase, perfect fix for my needs. Thank you I subscribed and liked! Again great content and nice editing!

Very Impressive!!! I just got into wood and epoxy and with all of the sanding, especially the epoxy I need a PAPR. They are way to expensive for me so this is a great option. Well Done Tony from Hilton Head Island, SC USA

Also your design is bloody brilliant and you made an instant subscriber out of me.

Thank you for sharing. I clicked on your Amazon links and ordered all of the parts.

Dude. Your thumbnail and intro to this vid are so good I had to watch it a few times 😁. Love it.

Genius idea for welding smoke.. Thanks !

Awesome. I've wanted one of these for absolutely years, but as a hobbyist can't remotely justify the cost. I've toyed with some designs for a DIY version, but never came up with something i felt great about. But you seem to have nailed it and I'll be making one of these immediately. Putting that on instead of my old rubber 3M on a 40C Texas summer day is going to be worth absolutely every cent. Thank you 1,000,000 times for the post. Cheers.

You just earned yourself another subscriber. Awesome job! Waiting on V2 and then I'll use your links to buy everything.

Your invention gives me inspiration to try and improve one that I built for short use using the inflatable air mattress pump with a filter on the intake and hose on the output then put it to a half mask through a hose that was for an hvlp mask. it wasn't full face but it worked for simple purposes and was less likely for fog up my goggles.

I've been wanting to make a powered pack for my 3M mask for a long time but didn't really know where to start so this video is awesome!! Thanks 👍👍👍👍👍

Went over and beyond Subscribed immediately 👍🏼👍🏼 Especially with the list

I’m definitely giving this a go, I would love to somehow make the welding helmet detachable so I can go straight from welding to grinding to painting! Thanks so much for a great vid!!

Unbelievable mate. Absolutely class, such great work. This looks like one ill be doing not really for welding but for knife grinding. Cheers bud 👍

Fantastic. Going to try myself. I've got a extract set up and usually use disposable carbon fiber mask which work out expensive. Thanks for the video. Also going make the BBQ forge but I can't weld very well so am trying a heart sink Copper pipe experiment with a little radiator just for fun so thanks for the inspiration (open system) 🤘

Genuinely enjoyed, liked AND subscribed! Thanks for sharing this you just saved me a ton of aussie quid!

This is nothing short of brilliant! 👍

Hi for those using a Makita 18v, the adaptors tend to not have the 12v conversion inside, unless you look for one with a torch! But you can use a plain adaptor as you're using the PWM reg anyway, so the initial voltage is not too much of a concern, but I would recommend marking on your PWM knob, 12v and 6v or making a stop so it does not over volt the blower. If you find the 12v part of the adapter fails as mine did you can connect the terminals inside directly to the PWM, so you will get the full 18v at the PWM just don't urn it up fully.

I saw your stag sculpture in the fire and iron gallery - amazing. can't wait!

This is exactly what I believe I'm desiring...GREAT Idea and Thank You for Sharing

I am absolutely making this

I’ve wanted one of these things forever. The units designed for wood working are only dust filters. I need something for organic vapors as well. Your design should cover all the bases. I’m an old geezer so the position of filter/ motor unit where it is could be problematic . But, hey, all the more incentive to get a good filter! Thanks for the information.

Brilliant effort. Great to see another use of a Milwaukee battery. Tool batteries are not just for tools but can be used on other projects if you put your mind to it.

This is codswallopping awesome! Love your polished well-researched DIY!!!!!Kia Ora form Aotearoa, New Zealand! :)

23:00 You can't get 'flashed' through glass. It's just a very bright light, & you might see stars for a minute. Great build!

What a Fantastic Video. I think ill be doing something similar for wood turning. Thanks for sharing

I ordered and assembled one. I used a CPAP hose instead of Dyson, but otherwise the same. Thank YOU!!

I do enjoy the fresh thinking! outstanding work.

Glad your back, great project something we all need

Excellent work, great design, clear explanation! Thank you!

Very well explained. I made a similar device prior, for dust and such. New to wielding. Thanks

Another class video. I'm a knife maker in a small shed. This makes sense.

I might piece one of these together if I can find cheap activated charcoal filter elements that will work for base coat/ clear coat. One thing for sure is I’ll be using your bottle shrinking trick.

I love the video more from the humour point of view than practical, by the way, The Speedglas picture is not. a G5-01. but a 3M Speedglas 9100XX FX Adflo Air Fed Welding Helmet a much older version than the NEW G5-01.

this is awsome. i have to wear glasses helmet earmuffs and respirator at my work and its hot and uncomfortable, i always take my mask of all the time cause i want to breath and wipe the sweat and condensation off and that defeats the point. ive been trying to make a design that incorporates my safety helmet and flip down face shield.

Very clever, well done Josh, i might have to try this.

You are a very smart bastard! That is simple, looks effective and could be useful for any of the dust disease jobbos. Well explained too. I will have to look for the bits in Oz, hmmm. Thank you.

WOW good old ebay 38 minutes after amazon tells me I no longer exist, purchased the lot, thanks Joshua, once it all arrives i'll send a picy

This is great. Maybe a suggestion to cut costs is to get a “3M Filter adapter”, this $17 piece will let you use much cheaper 3M cartridges. You’re buying basically the baseplate for the 3m organic vapor cartridge

Heh. It's like a CPAP for the active sleeper.

!!!! I need this!!! Thanks!

Thank you for the information Sir!!!

Thanks man. I'll build may own today.

Awesome job my friend and Nuff Respect from Jamaica :-)

Perhaps a small fan expelling condensation on top running by pipe to the rear with a cap end filter?

More proof that people are amazing. Thank you so much !

the lungs saved by this video the people that avoided cancer i wonder how many you saved with this video

Nice job.realy Nice job .Simple and works.very good.👏

If I could press the subscribe button again, I would. Another project that's been wondering in my mind. Though I was looking for something thinner. But such fans are way more pricey then what you came up with. Well done again ...

Amazing, this is real RU-vid

Nice job sir,. And a very good presentation,. Keep it up ☺️

I subscribed in 5 seconds Joshua. You wouldn't believe this, but I've bought a scuba mask and a 3A motor, and looking to put together. Found this! Loved the footage patrolling the shops! I was thinking of that as a screw you covid measure :D

Quite nicely assembled thing. All about the filter and as if it keep pressure in the mask positive of outside AND doesn't have "venturi" effect in any air connections I can't see it differing from any of the indeed _really_ expensive 3M stuff. I've been thinking to get powered respirator, but.....Man those prices are steep.

Dude. Mate. Im gonna parrot Alec and say 'this is bloody amazing!!!'. Im a bit of a PPE nut, cuz we only get one pair of eyes and lungs.... But $1500 for a PAPR is a bit out of my budget. This is the best DIY PAPR i could find on YT. The quality of your instructions and thoroughness of everything you need for the project, should be a template for all tutorials. i ordered everything through your links, except the spped controller, which was sold out. you should add the link for batteries and chargers too! big thanks man. you got a new subbie.

Very good video cool idea for Powered Air Purifying Respirator

Great video. I've just done something similar for my spray booth, only I'm tethered. I've piped a line to the outside where there's no contamination, and made a snorkel type head set to breath through. Being tethered isn't the the best but I don't have to move very far when I'm spraying.

Excelente ideia!!! No Brasil chamamos de "gambiarra" de sucesso 😅😅😅😅

Brother all I can say is AWESOME!!! keep it up my man

I enjoyed this video, and thought the idea was great. The battery adaptors are ingenious! I love the component for adjust the voltage! Never seen all this put together in such a compact way. As well as the snorkel mask. However the pump and filter system needs serious reworking, in my opinion. I am open to hearing responses and opinions. I'm learning too. At first I was so stoked, I was about to pull the trigger on ALL the components, but after hours and hours of researching and many rabbit holes, the day has turned to night, and I've realized now that I have several serious reservations and comments that you and your viewers should be made aware of IF using this setup for woodworking and some "in general" use insights. It's a great starting point, but it needs refinement. 1- these style air pumps have very short duty cycles; pumps like this are only meant to run no more than 5-10min, then they must rest for an equal or greater amount of time, they will burn out easily, b/c they are cheap. AND, these are very loud. I have one of these pumps for camping, it's embarrassingly loud to use in the outdoors when others are around to enjoy the quiet. I couldn't imagine having this mounted to my back. Even with over the ear headphones style hearing protection, if I could get those to work with the face mask (which i think was a super clever repurposing!), this pump would be annoyingly loud for me. I would have to go with foam ear plugs on a necklace. 2- the filters have activated charcoal inside. And most, if not all of these are made in china; meaning there's no certain quality control or even assurance of the product being what you're paying for. I researched filters for hours today, and many folks made comments on these filters not speaking highly of them. Some saying they can tap the filter and charcoal dust comes out. THIS IS DANGEROUS to breathe. BEWARE. My conclusion on filters: go with P100 filters, w/o charcoal. like these: www.fishersci.com/shop/products/scott-safety-p100-he-cartridge-40mm-connection/191202850 You mentioned using this system for welding, yes I could see this working better for that, if not welding for long period of time, and having minutes of resting betweens welds to allow pump to cool off. I would be using it in several areas: welding, milling lumber and woodworking. My conclusion is this needs much more refinement. Quieter pumps... cooling fans more likely. the pumps are not high enough quality and the filter can be dangerous. I ordered P100 filters that will work for particulates, paints, and sawdust. I like what this guy used to create his filter and air movement system: steampunkworkshop.com/respirator.shtml/ great idea in general! and maybe it'll work for some, though not for me. I think I'll take the best of your design and rework the filter /air flow design. Thank you sir for all your effort!

You are the legend ,man

Hi Joshua thank you so much for putting the time and effort to make a video I will be making one any idea when you will be doing V2 is coming out many thanks Mark

Thought I'd share that I've made another mod to the design. I found it awkward trying to shrink the bottle around the hose and facemask. So, I cut about the first two inches off the end off of the snorkel provided, and attached the hose to it. Now, it will just snap onto the mask and can be easily removed. This also adds a little more length to the hose, which I find helpful.

Genuine idea, I like it a lot mate. It is horrible joke, just for sake of earning some money, those companies still charge way too much for necessary health safety equipment. Thanks, I will copy it. I use two 14 inch fans at full speed to evacute air from my small garage, but I still develop cough after welding. It is simply not enough.

i'd probably combine it with the wolfsnout motorcycle dust mask. it's a semi-rigid mask that makes you look like you have a wolf snout. i don't have it yet but it looks pretty comfortable

good job!

This is great! I'm going to make one and use your links... thank you.. subbed and liked as well.

Hello sir! This build is AMAZING!! What is the ETA on V2? I'm a frequent flyer and would love to have this sooner rather than later! (Minus the welding portion, as they frown on welding on airplanes...)

I love this but I wish you’d gone into a bit more detail about connecting the adapter leads to the potentiometer. I’m certain I can figure it out, but it would’ve been nice to be able to watch you do it.

Yet another great video, build and DIY

Great stuff. Filtration is where it is at.

Your resourcefulness is akin to Yankee ingenuity! sorry just a bit of humor. Seriously, thank you very much for the great and inexpensive solution to a health and comfort issue and for the links to your components.

Just need this for painting 😍😍

Love this DIY PAPR system!! I saw this video and ordered the part’s immediately! This works great for my welding sanding needs, but I find when painting I can still smell the paint fumes and have to quit immediately. Is this because of the filter canister (P-A-2) not being rated for common spray paint?

Great job! I'll try to copy your idea... thank you so much

Thank you, I learnt loads from your tutorial. One thing though I might be wrong but I think the air pump is a brushed motor. If so you might be getting small carbon particle dust. Either way at the present time you can buy from China CPAP fans quite cheaply used in machines for sleep apnoea, they are brushless and perfectly designed for this purpose. All the best.

This.... is... gold... thanks :D

GENIUS!

when you made your own resin helmet add one, two or four mini dc dynamo fan on top, the backside or inside the side wall for air suction🎉🎉🎉compact and light weight

I love it. 🎉thanks.

Bravo!

Genius. Absolute genius.

Freaking genious.. I just got me a 3M second hand.

Outstanding!! Thank you!
