There have been several question regarding Protective Masks and what to buy. While I will attempt to give you as much information as I can, there is no way for me to know exactly what is best. I will try to make recommendations as to what civilian type masks can be substituted for military type masks, but that choice will ultimately need to be made by you the reader, based upon your budget and of course availability. The recommendations are based upon a comparison of the military M17 and M40 series protective masks.
First of all the primary function of the Protective Mask is too keep you from inhaling or ingesting harmful particles and/or vapors that Weapons of Mass Destruction (WMD) can cause. Our primary concern, ranked in order by me below, based upon likelihood of the type of attack. This order is my opinion and is not necessarily correct, but will still be useful in determining what protection is needed.
Please keep in mind an M17 and M40 series chemical-biological mask, when properly fitted and worn with the hood, protects against field concentrations of all known chemical and biological agents in vapor or aerosol form, but will not protect you when the air has a low-oxygen content, such as in tunnels or caves, or when the air has a high level of smoke mixtures. Do not use it for firefighting. It does not protect against ammonia vapors or carbon monoxide. It also is not designed for radiological protection. However, worn properly, it provides added alpha and beta dust inhalation protection, and individuals should wear it in all known situations until the contamination is identified. This will apply to civilian models of full face masks with the proper filters installed.
Some definition of terms is in order, so that no confusion of what a particular filter will protect against.
Fume - Vapor, Gas or Smoke (.001-1 micron in size)
Vapor - A substance that is present in a gaseous phase, generally exists as a liquid or solid at room temperature.
Gas - A substance that exists in a gaseous phase at room temperature.
Smoke - A cloud of vapor made up of small particles.
Mist or Aerosol - Fine drops of liquid sprayed into the air. (.01-10 microns in size)
3M?/span>Full Facepiece Respirators 7000 Series are designed to accommodate a wide variety of cartridges, filters and combinations. The 7276 Cartridge will filter certain organic vapors, chlorine, hydrogen chloride, chlorine dioxide, sulfur dioxide, hydrogen sulfide (escape only) ammonia/methylamine, formaldehyde 2 or hydrogen fluoride. This cartridge in combination with the 7090 P100 filter in a 7287 retainer should give protection equal to or beyond what the military specifications call for.
Millennium?Chemical-Biological Mask (MSA)
The Millennium Chemical-Biological Mask and the Advantage 1000 CBA-RCA Mask are effective against biological agents and these chemical warfare (CW) agents: GA, GB (Sarin), GD, VX, Mustard, and Lewisite. Testing conducted by MSA and independent laboratories assures that the gas mask and canister meet the requirements for effectiveness against CW agents using the test protocol recommended by the Chemical Agent Safety and Health Policy Action Committee (CASHPAC). They are also effective against OC (Oleoresin Capsicum) Riot Control Agent and HCN (Hydrogen Cyanide), but, again, have not been tested or approved by NIOSH for these applications.

West German Filter
East German Filter
German R-30 Filter
For those who have this type of filter, this is a reminder that this filter will expire on Nov 2002. After this filter reaches it's expiration date, use for practice
threaded filter 100% EXPIRED
Great filter, but currently expired
You can find these with the M24 and M25 protective masks.
Super Filter (Current American Made Filter)
type of filter is a good example of what never to purchase.
This filter has a BLACK ring on it, which means that it will only filter tear-gas and radiological particles...that is of course if the filter wasn't expired.
The correct color of ring is GREEN, for NBC rated...but still will not filter chlorine, ammonia or smallpox virus.
These filters are outdated unless you have years 1988 or better. The last known production date was in 1991.
If you have the 1988 made filters, they will expire in MARCH 2002 If the package is bloated then the filters are completely expired.
Do not use if over 10 years old . .
.You can find the lot date, (date of manufacture) on the can itself. Look for the code on the can
RFT  Date of Manufacture
are surplus filters . .
.The military converted over to the C2A1 filters
.C2A1 filters will not filtrate chlorine, ammonia or smallpox virus, (Which the M95 C/A filter has a certified capacity against)
Israeli 'Civilian' Protective Mask
This picture is mostly for informational
purposes, showing you what an Israeli mask looks like with a M95 C/A filter
on. These masks are very basic in terms of protection. They tend to leak without
the user knowing.
Your life will depend on the type of equipment you procure.
M10M Protective Mask
This type of protective mask should
NEVER be used for protecting against NBC warfare agents. Use ONLY for protection
Ardvark Protective Mask
Both of the Russian masks listed here and below are not even worth the trash bag to throw them away in. To put it nicely, if his s the type of protective masks you and your family have in your home when there is a chemical release, then you will be leaving your residence in "body bags". ------SORRY They do make nice conversation pieces.
Russian SMS Protective Mask
M9/M9A1 Protective Mask
Completly outdated. Uses a 60 mm
threaded filter which haven't been produced in a long time. Show item ONLY
C3 Canadian Protective Mask
Also known as the M69 protective mask. The Canadian Military rotated these out of issue because of problems with the voice-mitter leaking. If you own one of these you will need to check it with Banana Oil Ampules be sure to check around the eye pieces and more importantly, the voice-mitter.
The expired mask list was taken from the American School of Defense. http://www.asod.org/index.htm
I include it here in order to completely cover the dangers of having the above masks.
