Gas mask
I am currently looking for a gas mask for use with organics and fuming chemicals. The one that I am currently thinking about is this one:

And this cartridge:

Does this seem like a good choice to you? If not, what do you recommend?

I would personally suggest the Israeli civilian gas mask with a NBC (nuclear, biological, chemical) filter. The filter is the NATO standard and last
a reasonable time.

Looks like a decent all-around filter. Of course there are plenty of things that will probably make it through those filters unscathed so the only
way you will know it is a good choice is on a case by case basis. Just be aware of what you are working on and if your filter is rated for it. Of
course with a half-face you also have your eyes as a remaining liability. Goggles and glasses (unless you were wearing diving goggles) don't protect
your eyes from gases, chlorine, ammonia, plenty of lachramators will still tear at your eyes given the chance. Of course there is the social
liability of wearing a full-face mask (neighbors tend to treat it much more suspiciously) as well as comfort and cost to consider.

I was thinking of a full face one, but the $200 price tag killed it for me. Plus, I already have the face mask I listed here. I just need the filters.
On 3M's website it says that the filters protect from general Acid and Organic vapors, as well as Ammonia, Formaldehyde and, strangely, Methylamine.

I found another cartridge which seems to offer better protection:

What do you guys think?

you should choose the cartridge based on what type of gas you are likely to be exposed to.
http://www.lbl.gov/ehs/chsp/html/OdorThresholds-3MRespirator...
has some guides on the type of filter/cartridge to be used based on the gas (Ctrl-F is your friend)
also do remember that the gas masks are only for use for gases below the IDLH concentration (immediately dangerous to life and health)
i personally use a 3M 6000 full face respirator and haven't found any fault with it yet

I have to agree that a full face respirator is much better for most chemicals, if there is chlorine, ammonia, etc, it will be painful/harmful to your
eyes just as fast as your lungs, maybe worse for them. If you are only worried about particulates or toxic solids, then the half face is OK. But in
my experience, they are not much help in the hazardous areas that I have had to deal with, as dust, silica, acids, benzyl halides, etc are very
irritating to my eyes.

http://www.ebay.com/itm/Russian-USSR-gas-mask-FILTER-for-PBF...
I personally use this one seems to work for most of my stuff, I usually use it in combo with fume extractor though. I really like it because it covers
your whole face top of your head and side of your head and the filters are on the sides so you're not breathing what you're facing.. I have tested it
with things like ammonia and chloramine and cant smell them at all when im wearing it. From what I can tell when buying a gas mask the more cheap they
are the harder it is to breathe.
I dont know for your area but the isralei style gas masks are avalible at my local military surplus store for ~5-10$ no new filters though, the
filters closer to 25-40$ a piece, compared to the 20$ Russian PBF mask and 6$ pair of filters. When shopping keep in mind you need to have fresh
filters and the price can really add up so try to find one with cheap filters.
Also before buying your gas mask do some research on it alot of ones avalible to civilians at cheap prices are because they were flawed and became
obsolete, and therefore are not safe.

i have a czech double filter and ammonia odor still is detectable but faintly and no tears so they are good. i have a russian anteater looking one
with a single canister full of charcoal and is what i would probably use if cyanide was in the air.army surplus has them cheap for about 19 dllrs. and
filters sold separately in a sealed package,also cheap.better than nothing.

3M is way TOO expensive, and you don't have to buy 3M filters for your half facepiece mask : the "click-fit" system has been copied by a lot of
manufacturer and their masks/filters are just as reliable and much much cheaper...
Got a fullpiece mask I bought a year ago, it costs me half the price of the 3M mask with the same design (Sperian opti-fit twin) with 6 pairs of
ABEKP3 filters (EU standard). You may sometime feel unconfortable with such kind of apparatus, but it's worth your lacrymal system or corneal safety.
Take a look at Sperian, it's a manufacturer among others.
BTW : it's better to use 1 filter (or pair) for 1 specific use to avoid cross-contamination with chemicals, so buy a couple if needed...

Sorry to resurrect an old thread, but if anyone else is looking for gas respirators, I would seriously consider looking on eBay and searching for the
GSR (general service respirator). GB has just replaced its military respirators, and many of these brand spanking new GSRs are popping up on eBay with
bags and spare CBRN filters. Apparently they are quite comfortable too.

I personally got mine at Home Depot, I know it's not perfect but it's pretty nice. It's rated for almost all commonly encountered fumes in a lab. HF,
HCl, SO2, NOx (to a lesser extent), formaldehyde, and a wide variety of organic solvents. I'd go with the Israeli mask if you've got a decent amount
of money, I was on a bit of a budget.

I think I might need one of these for walking around the streets in my town where there is currently an uncontrolled coal mine fire. The whole town is
shrouded in coal smoke and there have been many hospitalisations from carbon monoxide poisoning, let alone the obvious respiratory issues you'd
expect.

Australia - in one of the largest coal mining areas in the country. The Government is censoring media coverage heavily and the whole event is being
significiantly downplayed, which is concerning. I have detected a thick film of sulphur dioxide deposits all over our house and car and even members
of my own family are displaying the text book symptoms of smoke intoxication and carbon monoxide poisoning.
The Gov is being elusive and the only data they have given us is next to useless - ie an "air quality index" rating, rather than actual data like
dangerous gas ppm levels etc Mind you, the scale is 0-150, 150 being the worst and our air quality is currently sitting at 950.
I think coal smoke contains a lot of metal particles and carcinogens that will likely cause a lot of long term health effects over the course of
ongoing exposure. The fires are not expected to be extingished any time soon.
