NO, you need a combinationfilter for that. P100 is only particles not vapors.

But don't go into an area that you need to have O2 replacement, this filters won't do that.

...Sorry, I guess this is a combination filter.
Just better versions. and still pretty cheap...

Yep, it's a combination.

P filters will only filter out particles and not vapours, that's what they are designed for. Particle filters work on the principle of very tiny holes while vapour filters are treated with solutions.

Combinationfilters have colorbands on them, Ammonia is darkgreen with the capital K. In most cases you won't find them separately but more in the combination ABEK togheter with a P3

A: organic gases
B: non-organic gases
E: Hydrochloric acid
K: ammonia

An ABEK filter is the best choice for handling gases since it has a wide range.

Yup!

You will however need a high rated ABEK filter, depending on the concentration. Much like P filters (P1 P2 and P3), ABEK filters have ratings. However, ABEK are rated on their capacity, not level of filtration. An ABEK1 filter will give you the same level of filtration as an ABEK2 filter, but the ABEK1 will be depleted sooner.

I have tried this out with a tank of butane. Butane saturates ABEK filters very quickly, and can be smelt even in tiny amounts. I released the gas for a few seconds, and then tried to breath around the tank. With an ABEK1 filter on my regular UEing half mask, I was able to breath very easily (as there was not enough gas to displace the oxygen). But more importantly, I couldn't smell any of the gas. This meant it was protecting me. But very soon after, the gas broke through the filter. I then tried this with an S-10 respirator: the standard issue NBC mask to the British armed forces. With a brand new filter off Ebay, I was able to breath around the tank for much longer before the butane broke though the filter canister. There is power that causes coughing and sneezing that is used to test P3 masks, but due to its nasty properties, it isn't easily obtainable.

You also have to be very careful with asbestos. While a P3 mask will filter out ambient and low level contaminations of asbestos, if you were say removing asbestos (or treading on broken asbestos), you would need a full face respirator. Even a $400 full-face respirator with P3 filters isn't enough to protect you if you break or saw asbestos.

Edit: It would probably be worth using an S-10 respirator for UEing, as the filter canisters are rated ABEK2-P3. I got mine for £20 off Ebay

You must be extremely careful if you go someplace where the oxygen can be displaced by other gasses or vapors. All the filters in the world won't help you if there is no oxygen where you are at. Specifically, below grade areas are susceptible to collecting heavier than air gasses.
Just be aware of this fact.

Don't worry, it's an open building with broken windows. It just reeks of ammonia.

If ya wanna filter out amonia, get an SCBA.. You'll only get 30 min per UE but whatever...

Scuba shops should be able to recharge it for a fee..

No, you do not want SCBA. You want either an ABEK1 filter, or a K2 filter. You can get each letter in individual filters, providing higher air cleaning capacity.

A = Organic vapours and gases

B = Inorganic vapours and gases (NOT Carbon Dioxide or Carbon Monoxide)

E = Acidic vapours and gases (eg. sulphur Dioxide)

K = This is the one you want: ammonea, and ammonea derivatives, vapours and gases

The number after the letter(s) is how much of the contaminant that the filter can take before it is used up. In your case, when you can start smelling ammonea, that means your filter is depleted. For your purposes you just want a half mask like this one:

Or for more high risk locations, a full face mask:

They can be fairly expensive, this one was $80 (but I got given it for free because it was an old model). However, you can get them very cheap. I got this one for $20 off ebay, including a brand new filter (ABEK2 P3):


Although it can seem overkill, it is well worth the money of you are visiting a location that is contaminated with chemicals. As for low Oxygen levels, unless it is something REALLY worth seeing AND you have all the correct equipment, its best to stay well away.

I'm not sure about SCBA equipment, but a dive shop will not sell or service SCUBA equipment unless the buyer is licensed to dive. There might be similar restrictions on getting non-scuba tanks/regulators.
