Reddit reviews 3M(TM) Half Facepiece Respirator Assembly 6291/07002(AAD), Medium, with 3M(TM) Particulate Filters 2091/07000(AAD), P100

Wearing protective gear IS really important. However, please be aware that the mask you are using is only rated for nuisance dust, not any sort of chemical, or any of the really small dust particles, which are the most dangerous. A real respirator rated for organic vapors is not expensive and much more effective. If you can smell the chemical, you're still inhaling it.

For soldering and painting a mask like you have in the picture gives a false sense of security.

Edit: On my PC so adding - you can get a 3m half-mask respirator for $15 on amazon with pink P100 dust filters. Disposable masks are typically only P95, meaning they only capture 95% of dust, and it's the small dangerous bits that get through.


Multi vapor filters are $8.75. Store them in a plastic bag and they'll last a long time. You can't smell anything when using these, if you do the filter is worn out.

If you are making toxic dust and fumes (sanding paint, welding galvanized metal etc) or don't want to swap them out, use multi-vapor cartridges with P100 dust caps.

Here's a costume if anybody actually wants to dress up:

Chemsuit

Respirator

Gloves

$15 well invested friend, you only have one set of lungs.

It's not the goggles it's the dust mask. Those mask are not really that effective. They don't seal well, which is why your goggles fog up. All that air getting out and fogging up your goggles is equal to the amount of dust your are sucking in.

I wear glasses and goggles, but I wear one of these. It's actually a lot more comfortable to wear for long periods of time than a paper mask. I also have the organic vapor cartridges for when I spray finishes.

Buy an air filter! I have terrible asthma and my buns' hay sets me off so badly I use a filtered respirator to clean their cage.

I have two air filters and it makes a HUGE difference. I have this one by the buns: Honeywell HFD-130 Germicidal Tower Air Purifier with Permanent IFD Filter, and this one by my bed Sanyo Air Washer Air Purifier.

The bun-filter is a monster. It's nearly 2 feet tall and can be a bit loud on the higher settings, but it's got a washable filter inside. You would not believe the GUNK that comes out of this thing when I clean it. It keeps the dust from the hay down pretty well and provides white noise to keep the buns from flipping out over every passing car too.

The other filter I haven't had long enough to say if it's good or not, but it's fancy and quiet. It shoots out water from the top and has "odor detection". I say get the monster. :)

If by "dust mask" you mean one of those white paper things, then yeah - get a nice P100 respirator:

Less than $17. Maybe $25 in-store? A pack of disposables probably costs at least half that, and the difference between the two is night and day. You won't smell a fart in the $17 respirator. A disposable mask should be disposed of, rather than used for some imagined protection. (OK, it does block 95% of non-oil-base airborne particles - better than nothing, and better than a rag. But that means it lets 5% through, and is only guaranteed if you have a good deal, which you won't. The respirator will block 99.97% and has a comfortable silicone seal.)

Note that I am saying this purely as a general advice when working with dusty stuff: I have no idea if there's something especially dangerous​ about the finish. The clear coat is probably a urethane, no special danger. The paint might be lead if it's old.

Also, if you have a lot of it, run it through a thickness planer instead of sanding. You may have to sharpen (or clean gummed up) knives afterwards, but the shavings are large, lower dust, and relatively easy to clean up, you won't go through acres of sandpaper, and it's so much faster and easier. And in theory, there are no nails.

Thanks. Here is the respirator:

My bad, I didn't notice the delivery options. Crazy that Amazon could have stocking issues from how big the wildfire problems are.

​

You can also try mixing up search terms for disposable/nondisposable masks and higher NIOSH ratings - there's one $20ish for an older 3M half mask model + 3M P100 cartridges, one and two day shipping available if I read it right.

Do yourself a favor - buy a respirator. They're like $15. Your future self thanks you.

Safety glasses and a big face shield are critical. If I'm grinding a lot or grinding ANY thoriated TIG electrode I'll add a respirator with the pink P100 filter cartridges. Don't forget hearing protection! If you wear earmuffs then behind the neck ones like these will fit with all the other gear.

I don't if I'm rough turning green wood, but usually do wear one if I'm turning dry wood, and always when sanding. I use this one from 3M, which fits under the face shield pretty nicely and isn't too uncomfortable.

The general advice I've seen on /r/HomeImprovement is that if it is a pre 1977 house, assume it has asbestos.

As far as mitigating, I've seen wetting it down before removal, using a HEPA face mask, sealing off areas you aren't working in and changing furnace filters afterwords can remove a significant amount of the risk if you're DIYing it. And encapsulating it (putting another type of flooring over it) should remove any threat too.

I guess as an average homeowner, asbestos wouldn't be something I'd actively worry about. Radon on the other hand.....

• If you're going to weld a lot, use a respirator, at the very least a disposable one but I'm using this one from 3m and it's worthwhile, although the filters can get expensive.
  I had fume extraction at my welding school and it still didn't do the job, although stick is even worse than MIG. Nowadays I'd never weld without a respirator.
  
  
• If you're doing stringers in T joints, rest the nozzle on the bottom plate and they will come out perfect
  
  
• If they have synergic and non synergic machines, use the non synergic ones or you won't learn to set up the wire feed and voltage separately, I find I've learned more with older machines that you have to fine tune to perfection than with newer machines that will run smooth almost no matter what you dial
  
  
• Don't hold any questions for yourself, be annoying if you have to, but get the most out of your teachers now in school and later when you work try to stick around the good welders and ask a lot of questions

I can get this for $18.00. You'd probably also want a set of these ($9) to keep out the volatile organic compounds present in most spray paints. If I bought both of those, it'd be over $25 and would qualify for free shipping. (To me in the US.)

Postal shipping from the US to Oz would probably run $28-35 though. Let me know if you want to do it, and I'll PM you my PayPal details.

I have this 3M one and I use these filters on it. Honestly, I've used it only a handful of times in the 8 years I've been exploring. Once in a place full of black mold, another in a place where all the insulation had fallen onto the floor and created a dust cloud as you walked. It's kind of a personal judgement call. If you feel more comfortable wearing one all the time, go ahead. Just don't get a gas mask unless you want to look silly (or like a bioterrorist).

What I consider essential on the fabrication side:

Huge air tank and hoses. Lots of air tools (glue sprayer, paint sprayer, saws, cutoff wheels, air chuck, nail gun, etc). Seriously, this gets a ton of use and is absolutely necessary IMO.

Table saw. Must have a sturdy fence and be able to rip at least 2 feet wide. Rockewell is basically the cheapest one I know of that's decent. Take a look online, lots of people selling higher end ones, used, for a few hundred.

Router with circle jig and the appropriate bits.

Decent quality drill with spare batteries (I'm currently using the 20v lithium Dewalts, they've been great). Jig saw (I like the Skil brand with laser guide), reciprocating saw. Various drill bits, unibits, and saws.

Palm sander, and pads with various grits.

Bench grinder (wire wheel and stone if possible). I keep a full size angle grinder around as well, with some flap and cutoff disks.

Bench vise.

Propane torch, preferably, with easy-start (no striker/lighter, a button start of some sort)

A decent quality dust mask. I use these. Trust me, it's WAY better than breathing in fiberglass dust, or even just MDF dust.

Tons of latex gloves, "chip brushes", and cheapo tupperware for resin work (mix in tupperware, let it dry, bend to crack out resin, re-use until it's destroyed).

Sawhorses, or at least, durable garbage cans.

Shop vac.

Razor blades. I buy single-edge 100 packs and just throw them away as soon as they're not sharp. For cutting carpet, vinyl, etc. it's much better than scissors.

A decent quality hot glue gun and lots of glue sticks (this is how you position rings for custom doors, dashes, etc)

Less than $1 each:

Fits better on your face and filters out 99.97% of particulates, with replaceable pancake filters.

After pulling up some carpet and enduring sneezing and a swollen face for 2 days (I'm highly allergic to dust mites), I picked up this respirator: http://www.amazon.com/3M-Face-piece-Reusable-Respirator-Assembly/dp/B000FTEDMM/ref=sr_1_2?ie=UTF8&qid=1377109831



Cheap, comfortable, replaceable filters, and works well. Not a single sneeze after pulling up more carpet for 4 hours.

Those particle masks will only help so much, in order to be better protected you need a good seal around the face.

Amazon prime one of these and stay safe!

Well if you don't mind puking your brains out for a day or two, by all means weld away bud! BREATHE DEEP! lol Trust me man, don't do it...you will regret it, death is probably favorable over the sickness you will experience.

Just grind off the galvanizing in the area and make sure you are in a well ventilated area and out of the smoke plume. I would probably wear one of these too.

For yard work and mowing the lawn, I wear one of these: 3M(TM) Half Facepiece Respirator Assembly 6291/07002(AAD), Medium, with 3M(TM) Particulate Filters 2091/07000(AAD), P100 https://www.amazon.com/dp/B000FTEDMM/ref=cm_sw_r_cp_apa_EfSyzbTQQKPSQ

Breaths pretty easily, gets uncomfortable after an hour or so. I'm still looking for something more appropriate for outdoor exercise.

it's this one - the one you linked doesn't filter out asbestos. I bought the same one for my first trip myself, but this one I've linked definitely works

For scope: get a used tek on craigslist

For function generator: this kit

For iron: Hakko 888

You probably want a bench PSU as well: Korad 3005D

You need safety gear too!

• Respirator - half face with P100 filters
  
  
• Goggles
  
  
• Gloves
  
  Don't forget blank PCBs and etchant, breadboard, jumper wires, etc.

I have what they call an "E" container that is about 4 quarts. Puts out 2L/min for 2 hours. Portable concentrators are HEAVY. Work in well ventilated areas as the co2 it emits in my house gives me a headache (not enough airflow in lungs to get rid of excess co2 concentration).

Respirators like this would work if I could get a NIOSH95 rating filter. Seems like it would work and then have to find a way to get air to feed into it behind the filter.

I'll look into non toxic silica too. Maybe I could put some of those inbetween the filters?

Problem is that I have to wear these because I don't make tears anymore and need to protect from wind/keep moisture in. It's very difficult to wear TB n95's, circle n95's or even viral surgical masks without having fogging/comfort issues.

I don't know a whole lot yet about knife making, but I do know that if you are grinding metal you need to be wearing respiratory protection. Metal dust is no bueno for your lungs. In the limited reading that I've done, a standard 3M respirator mask with the P100 filters should be sufficient. [The price is right too] https://www.amazon.com/3M-Facepiece-Respirator-6291-Particulate/dp/B000FTEDMM/ref=sr_1_5?ie=UTF8&qid=1468293781&sr=8-5&keywords=3m+respirator

I know OSHA regulations don't allow for a beard when using an N95 mask and only allows for limited facial hair, IE goatee or mustache, so take that for what its worth, YMMV.

I ran 14 miles in a half face air mask at 8:40 pace! I was surprised I could keep such a good pace, though, because those things are a pain to breathe through.

Was glad I had it tho because running in that smoke without it is even worse.

Here's the P100 mask I bought, is this any good? https://www.amazon.com/gp/product/B000FTEDMM

Since you're trying to work a tight budget, I would skip the Sorby tools and opt for some less expensive HSS options. Sorby makes some of the best HSS tools on the market, but the price premium is rather high for the name. Personally, I'd suggest you opt for Hurricane as starting tools and then make the decision to go for more expensive tools down the road.

Hurricane are solid inexpensive tools and you can pick up way more tooling for $14 more than the tools you have listed. That set gets you a bowl gouge and parting tool, which are both fairly important. Take one of the scrapers and regrind it into a negative rake scraper - I'd use the 1" since a scraper that large is very likely to stall that HF lathe.

I'd also recommend spending the extra dollar now on a respirator and some P100 cartridges. This is the sort of thing you really want to have up front and is far more important than a sharpening jig - you can always learn to hand sharpen tools, you can't un-COPD your lungs later on. Many people who learn freehand sharpening swear by it and prefer it anyway. Luckily, you can pick up a solid 3M mask with filters for under $20 on Amazon.

So, for about $35 more than you're currently looking at, you can add some safety and get way more tooling for your money, at the expense of having to sharpen a little more frequently.

Like any safety gear:

1. Anything is better than nothing
   
2. No safety gear is 100%
   
3. Everything is inbetween the two
   
   This is what I use, but I also use it for sanding bondo, painting (with different filters) and working with cutting/grinding G10 and fiberglass which is way nastier than wood.
   
   If you don't want to bother with a full respirator, the P100 is a good doctor-type cloth mask
   
   If you really look into it and are the paranoid type though, you'll realize your chance of trapping any of the 30nm and smaller dust particles are basically 0, which can be a problem because they're the ones that get deep into the lung tissue. But anything like the above will work fine for trapping the bigger stuff. People spend thousands of dollars on systems to trap or get rid of the smaller particles, but unless you're a serious hobbyist, ie: exposed for many hours a day, it's overkill. Source: Working on a dust collection system for my grinder with exterior vents and basic filtration. It's a pain in the dick.
   
   Best way to minimize the risk? Do it outside. Dilution is the solution for pollution. This isn't a post to scare people so much as remind them that literally everything can be hazardous in some way. Just take regular precautions to minimize the risk and enjoy what you're doing.

Despite what people say you should always use a respirator and not a dust mask. Atomized acrylic paint and air brush cleaner are no where near save to breath. I would suggest this one, or this one.

It is save to say that they are non toxic when used with your paint brush, but you don't want to atomize it and breath it in. Like you don't want to huff anything out of a spray can.

So would this pack of N95 Respirators be good for me to keep some in my car, at home, etc?

Also, now that you've taught me so much and I'm researching everything is there any advantage/disadvantage to having at least one of the P100 Respirators on hand?

What common things would a P100 be better for than an N95?

What things would you use your N95 on to prevent wasting your P100?

Definitely decent hearing protection and a respirator, I use this one and it works great. Save your lungs and your ears.

I ordered a similar mask for $20 with a set of filters included and will have it on saturday

Pick up some neoprene gloves for oily woods like that, especially if they're already causing irritation. I don't know about cocobolo specifically, but many woods can have health effects if inhaled, or you touch the oils too much, and you can become more sensitive to them as you work with them more. Also pick up a respirator, I have an older model similar to this one, and it's quite nice, doesn't bother me in the slightest.

I've got one of these for when it gets really bad. Also brought one of these out last year. It wasn't uncomfortable but you probably wouldn't need it unless it was storming for hours.

3M provides a HEPA mask which I've found to be great. A dust mask won't work, you need a HEPA.

Pick up one of these.
