7 Best Gas Masks - Reviews
1. Mira Safety CM-6M Gas Mask- Top Overall Pick
Our overall top pick spot is always a little ‘claim to fame’ for the product we choose. Why then has the Mira Safety CM-6M gas mask been awarded such a prized position? Well, we are about to divulge some insider knowledge, so listen carefully!
You may not know this, but this exact gas mask is used by government agencies across the GLOBE, including those of Norway, Portugal, the Czech Republic, Lebanon, Turkey, Saudi Arabia and Chile! If it’s good enough for these governments, it is more than good enough for us, right?
If the thought of chemical, biological, radiological and nuclear weapons or materials has ever haunted your nightmares, then this mask is definitely the one for you, as it goes above and beyond to meet all CBRN protection standards. Rest easy, there’s no need to worry anymore!
An unrestricted view is of utter importance when you are in an emergency, so this mask has been designed to include an expansive lens to provide perfectly panoramic visibility when you need it most.
However, lens size isn’t the only thing that will prevent you from seeing clearly — fogging also plays a pretty big part in that! Thankfully, the hypoallergenic inner mask completely eradicates the risk of fogging, so you are all prepared and ready to take on the world.
What really sets this mask apart from other similar products, I hear you ask? Well, that will be the rigorous testing it has undergone to ensure it can withstand mustard gas for up to 30 hours — leaving you completely unscathed and safe!

2. SAS Safety 7650-61 Opti Fit Gas Mask - Best Value for Money
Our best value for money slot is taken by this tried and tested full face respirator.
Regardless of your head size, this mask is guaranteed to fit you, as they come in aptly named ‘small’, ‘medium’ and ‘large’ sizes — each, by the way, has easily adjustable straps, so don’t think your measurements have to match up exactly.
The tight seal you need for a functioning mask is well and truly there with this one. Plus, the silicone edging makes for an extra durable and wonderfully comfortable feel.
Visibility without exposure is perfect in times of crisis or when dealing with potentially harmful substances in a work environment. Luckily, the full-face aspect provides a large, yet covered viewing area.
SAS Safety pulled out all the stops by going one step further and coating the wide lens with an anti-scratch film! Not to mention the nose cup that prevents any fogging from occurring and distorting your vision.
Side note: you might want to swap your glasses for contacts before putting this on.
3. Parcil Distribution PD-100 - Top Choice for Chemical Gas Mask
Do you work with chemicals or any toxic substances? If the answer is yes, then this Organic Vapor Respirator is the one for you.
Complete with dual filter cartridges and a scratch-resistant, impact-proof lens, you will be kept far away from any nasty gases.
While the fit of all of these masks must be relatively snug in order to create a tight seal, this one has been expertly designed to ensure maximum comfort despite this fact.
Don’t worry, the manufacturers haven’t let style overrule safety, as they have made sure to include an anti-fog and anti-scratch layer on the lens to ensure complete visibility in all conditions. They didn’t stop there either — this mask allows you to have access to your peripheral vision! What more could you possibly ask for?
This company is as confident with their product as they should be. How do we know this? Well, they wouldn’t offer a 100% satisfaction guarantee otherwise!

Preppers look away now! This one won’t save you from biological warfare, but it will protect you against smoke fumes and dust particles.
3M have made sure to integrate features that will increase their mask’s usability. How? Their specially-designed quick latch component offers speedy application and a unique ability to take the face piece off when you move out of the contamination area.
No matter the size of your noggin, this half face mask is bound to fit you. It comes in small, medium and large sizes, each with a customizable head cradle for a fit that is specific only to you. Perfect for those with oddly-shaped heads.

6. Mestel SGE 400/3 - Top Gas Mask for Volcanic Gases
In situations where volcanic gases are a threat, you need to make sure you have the best personal protective equipment out there, as you can find yourself in highly dangerous situations, as we’re sure you’re aware!
Fortunately, the Mestel SGE 400/3 gas mask provides absolute protection against nuclear, biological and chemical substances.
Not to mention that the one-piece full visor offers complete visibility of the scene around you. To add even more bragging rights, the lens is also fully scratch- and solvent-proof.
Besides ensuring you are left well alone by any fumes, physical impact won’t be able to harm any part of your face either. How is this possible, you ask? Well, that is down to the polycarbonate body which has undergone lab tests to prove its ability to withstand a bullet. You can’t feel safer than that.
Regardless of the temperature, this mask will never mist. This is all thanks to the perfect ventilation system it has — the masterfully-designed shape of the internal ring nut spreads air flow across the entire face piece, which acts as an anti-fogging mechanism.
Don’t be fooled by the heavy look of the product; it is surprisingly lightweight and easy to carry.
Hint: You will most likely need some practice in putting it on and taking it off, so don’t wait until a real emergency before you try it!
