What is Mira Safety CM-7M

What is Mira Safety cm 7m

As aforementioned, the Mira military gas mask manufacturers make it using military-grade technology to offer maximum protection against CBRN agents and toxic chemicals. Mira safety has designed the mask for use with a rifle. The masks feature a dual visor system and an inhalation valve for eye relief and closer cheek weld, respectively.

How to Use Mira

The Mira safety CM-7M mask works in 2 ways;

First, it filters particles like how a water filter works and eliminates bacteria in the oxygen you inhale. It acts like a physical barrier, much more like a cloth put in your mouth to prevent smoke inhalation, but the mask prevents the inhalation of finer particles.

The second method is a chemical process that involves the adsorption of toxic gases. The process differentiates gas masks from respirators or wet cloths that people use over their mouths while running from burning buildings. Damp cloths and respirators trap particles, but they cannot filter toxic gases.

Are MIRA Safety Masks Good?

Mira safety masks are very comfortable on the head. They have advanced features that make them better than other masks available in the market. While using these military masks, you don't have to spray anti-fog spray in the visors to make your vision clear.

FAQ

Selecting the right gas mask filter is as important as selecting the suitable mask. Proper research will help you find a gas mask filter that fits your mask and effectively filters and cleans breathable air in an NBC or CBRN environment.

Here are some of the frequently asked questions regarding Mira safety masks and filters to help you get the answers you need.

How Long Does Mira Filter Last?

Mira gas mask filters typically last 12-24 hours. But they can last for fewer hours if you are in a highly contaminated area. Generally, you can use filters until they become damaged, clogged, or soiled.

Environmental factors play a critical role in the lifetime of filters. Ideally, you should use the mask as few times as possible, especially in the case of nuclear, biological, and chemical exposure. It is vital to have multiple filters if you have several hours of exposure to toxic substances.

How Long Does a CBRN Filter Last?

A gas mask filter will last 12-24 hours in a CBRN situation. However, it will also depend on the concentration of the hazardous chemicals the CBRN filter is filtering. If the environment is closed with a full concentration of thick toxic gases, the mask may only last for a maximum of 1 hour.

Where is Mira Safety Located?

Mira safety is a renowned family-owned company located in Austin, Texas. The company manufactures and distributes top-quality tactical gears, respirators, and safety equipment.

How Many Times can you Use a Gas Mask Filter?

organic substances, tear-producing gases, carbon monoxide, harmful microorganisms, and other highly toxic substances you cannot reuse the filter.

In most cases, we recommend changing gas mask filters after a maximum use of 2-3 weeks since the activated carbon in the masks will lose its potency. As mentioned before, most gas filters in CBRN/NBC situations can last between 12-24 hours. You will know it is time to change the mask when you have restricted breathing.

How to Know When to Change a Mask Filter

The use time of a filter depends on various factors, including environmental conditions, breathing rate, contaminant type, and toxic gas concentration. Generally, we advise using a filter for 8 hours and changing it. When you begin having labored breathing or smell something inside the mask, it is time to swap the filter.

How to Use MIRA CM-7M and the NBC-77 Filter

The Mira CM-7M and the NBC-77 filter provide a powerful tool to protect yourself from terrorist attacks, cases of airborne contamination, natural disasters, and dangerous industrial chemicals. The combination will go a long way to ensure you are safe from all airborne threats.

The NBC-rated gas mask filters offer excellent protection from hazardous substances like nuclear, biological, chemical, and radiological agents. The Mira safety CBRN NBC-77 SOF Gas mask filter is pretty costly, but it has a longer lifespan. The filter has a shell life of 20 years, which is four times the lifespan of other filters, making it the best filter for civilians. The filter is popular among police, first responders, civilian contractors, and military personnel.
