2023 Best 40mm Gas Mask Guide by Parcil Safety

What's the best gas mask for you?

Whether you’re working in emergency response, disaster cleanup, or just preparing for the worse, there’s a gas mask option out there for you. Deciding which one to go with can get tricky. A gas mask, sometimes referred to as an “air purifying respirator”, offer’s the wearer protection from inhaling airborne pollutants and toxic gases. Things like what gas you’re trying to filter out, duration of use, concentration levels of the gas, and how ventilated the area you are working in are all factors in determining the right gas mask for you. Some elements you want to look at in your mask include how many filter ports the mask has, what type of material the seals are made out of, level of impact resistance on the face shield, communication needs, and head harness style preference.

Common Applications and Situations for Gas Mask Use

There’s a variety of situations where a gas mask may be applicable. Most people believe it’s just needed during chemical or biological warfare situation or where nuclear materials are present. However, there are a lot of times where you may need access to a gas mask and it may not have anything to do with a warfare or nuclear situation. Below are some common environments where you may need a gas mask, but for a more in depth look, check out our blog post on why everyone should have a gas mask (https://parcilsafety.com/blogs/parcil-distribution/why-everyone-should-have-a-gas-mask).

• Natural Disasters
• Dangerous Environments
• Pandemics & Contagious Diseases
• Nuclear Warfare
• Chemical Attacks
• Nuclear Power Plants
• Unruly Protests and tear gas

Common Features of a Gas Mask

A lot of different gas masks look very similar. But there are multiple features to a gas mask and these features ultimately make the difference on determining which one is right for you and if you are getting a quality mask or not.

Seal Materials

Gas Masks typically have internal and external seals to help keep good air in and bad air out. There are two materials that most seals are made out of: silicone or butyl rubber

1. Silicone – silicone is the most common used material in gas mask seals – an excellent, affordable option for ozone gas protection and organic vapor and particulate protection such as tear gas or pepper spray, however, it doesn’t withstand highly acidic gases very well.
2. Butyl Rubber – butyl rubber is known for it’s excellent sealing properties (commonly used in manufacturing vehicle tires) and its resistance against highly acidic gases. Typically, if you are using a gas mask for protection against chemical or biological warfare agents or a nuclear fallout situation, you will want Butyl Rubber seals on your gas mask. (A great article on how gas masks are made and why certain materials are used can be found at http://www.madehow.com/Volume-3/Gas-Mask.html).

Face Shield Impact Rating 

One thing a lot of people don’t think about when selecting a gas mask is whether or not the face shields are impact resistant. Will you be in a situation where you made need to protect your eyes and face from flying debris or blunt force? Then you may want to make sure that the gas mask you select is rated for impact resistance. The most common impact resistant standard is ANSI standard Z87.1, however some more expensive gas mask face shields can also have ballistics-grade resistance.

Filter Port Options and Location

Another factor you may want to consider is how many ports come on the gas mask and where the ports are located.

1. Central, single 40mm port – great when you only need to don one filter at a time and are needing access to both the left and right side of your body.
2. Single 40mm port, left or right side – typically used when you are needing to cant a rifle or need to operate something with one side of your body. Another great read on operating a firearm with a gas mask - https://www.swatmag.com/article/good-guys-wear-masks-operating-with-a-gas-mask/.
3. Dual 40mm port, left AND right side – If you are wanting lower breathing resistance or needing a mask for longer term use, then you may need 2 40mm gas filter canisters attached to your mask. Dual 40mm ports were designed with this in mind.

Head Harness Material and Type

Often times this one get’s overlooked, however if you plan on wearing a ballistics helmet or hard hat, or have a sensitive head, you will want to consider the head hardness strap material and points of contact. For material, typically we see silicone or mesh cloth head harnesses:

1. Silicone – more affordable, flexible option typically used in more industrial or short term environments.
2. Mesh Cloth – more comfortable to wear for longer amounts of time, and fits better under a helmet.

Next, is the connection points to the mask. You typically see gas masks with 4-point, 5-point or 6-point head harnesses

• 4-point – least comfortable to wear, doesn’t always provide a comfortable fit
• 5-point – most common, provides good comfort and stays tight in short term use
• 6-point – spreads out pressure points, decreases cranial pressure and is recommended if you plan on wearing a hard hat or ballistics helmet.

Voice Amplifier - Included or Not Included

The final factor when determining which gas mask to go with is whether or not it comes with a voice diaphragm or voice amplifier. The two most common are mechanical and digital:

• Mechanical voice amplifier – typically made out of a metal or plastic – it reverberates your voice and amplifies it slightly so you can communicate with people in close proximity.
• Digital voice amplifier – digital or electronic voice diaphragms typically work like a speaker phone. They amplify your voice through a mic and a lot of time includes a built in radio so you can communicate with people from a distance.

BONUS FEATURE!

If you are shopping on a budget or just don’t want the hassle of buying a gas mask AND a filter separately, consider purchasing a gas mask bundled stock with a filter canister. This can save time and money.  Both Parcil Safety’s ST-100X and NB-100 come bundled with a 40mm gas canister.
