The mask is not meant to be used for firefighting and does not provide protection from radiation, however the filters will stop irradiated particles from entering the respiratory system of the wearer. The mask offers protection from chemical and biological warfare agents, but does not function properly in places where oxygen content is low. The US armed forces henceforth returned to 'traditional' designs of mask where filter canisters are mounted externally and thus can be changed if needed without the wearer having to remove the mask. The design of the mask with it's internal cheek filters means that it must be removed by the wearer to change the filters once they are expired or clogged, thus compromising it's protective capabilities in a contaminated environment. It was for this reason that the resuscitation tube system was no longer issued for the A1 and was dropped on the M17A2. The casualty would remain unmasked, and would continue absorbing the contaminated environment. The problem with it being the exposure of both soldiers to contamination, the soldier giving aid ran the risk of encountering resistance from the airway of the casualty, pushing air back into his mask and breaking the seal on it. Other components attached are mask hoods to protect the head and neck area, a winterization kit to prevent frost accumulation during cold weather conditions and optical inserts for soldiers with vision defects.The M17A1 was designed with intent to allow a masked soldier to provide artificial respiration to an unmasked casualty, the resuscitation tube was a noble idea gone wrong. It also contains a M1 waterproof bag to protect filter elements from water damage. The mask is packed in a carrier that also contains other items like a nerve agent antidote kit (NAAK), a convulsive antidote for nerve agents (CANA) and an M-258A1 decontamination kit. These protective masks have inbuilt voice emitter systems that facilitate communication, a tube for drinking water from the M1 canteen cap (A1 & A2), and a pair of outserts to protect eye lenses and an air pathway that reduced fogging. Notable copies include the Bulgarian PDE-1, Japanese Type-3, the Polish Mp-4 and the Czech OM10 or M10M. Many countries have copied the M17 design. An experimental transparent-silicone model called the XM27 was designed in late 1966, but was turned down in favor of the XM28E4.

The M17 series includes three types of masks, the M17, M17A1 and M17A2. Filter elements in the face piece prevent harmful agents from entering the mask.
The mask has different components including a filter, a face piece and outserts.
Air Force replaced it for the MCU-2/P Gas Mask. Army and USMC in the mid 1990s while the U.S. Military until it was replaced by the M40 Field Protective Mask for the U.S. The M-17 was issued to troops in the Vietnam war, and was standard issue for the U.S. The M17 Protective Mask is a series of gas masks that were designed and produced in 1959 (as a replacement of the M-9 gas mask) to provide protection from all types of known chemical and biological agents present.
