Mira Safety ParticleMax P3R Virus Filter One Unit Only

Q: Can a 40mm NATO filter protect against COVID-19?

A: 40mm NATO is a thread designation, not protection destination. For protection against COVID-19, you would look for a 40mm P3 filter.

Q: Viruses can only survive on surfaces for a period of a few days maximum. So if the only concern is only viruses like the coronavirus (and I don't have to worry at all about exposure to chemicals, etc.), why is it that gas mask filters cannot be reused after a few days, when any viruses that were on/in it will no longer be a danger?

A: For safety reasons, we cannot recommend reusing any filter. This would go against all safety standards set out by regulatory agencies all over the world.

Q: Will this filter work against deterrents used by LE such as tear gas or pepper spray. If not all, which ones are not covered?

A: No, it will not, as this is just a particle filter. We would suggest the DOTpro 320 or NBC-77 SOF for riot control agents.

Q: I am using cerakote to coat and spray on multiple objects, will this be suitable to keep me safe? I would like to use my respirator that will take 40mm NATO instead of buying an additional mask for this task.

A: As cerakote is a solid particle traveling in a liquid aerosol, yes, this filter would work to keep you safe.

Q: I just bought the cm-6m. If I took the mask off in a controlled environment and left the filters in the mask after I had used it would they be okay? N95 masks are reusable until they are not structurally sound.

A: That depends on if the filters were used with live agents. If they were, they are considered toxic waste and must be disposed of for safety. N95 masks are only reusable so long as they are used with simple particulates (not viral, biological, CBRN, etc).

Q: I have some expired CNBC filters. I know the carbon aspect of the filter is what expires... Will that filter still remove COVID-19? They are still in original airtight packaging (40mm NATO type). Looking forward to the arrival of the order I put in with you all. I know you are severely backlogged. Your services are certainly appreciated!

A: We cannot say for sure, as even particle filters have glue in them which can begin to flake over time, leading to gaps in the particle filter. For the sake of safety, we only recommend using in-date filters.

Q: How many microns do these filters go down to?

A: The ParticleMax P3 will filter down to 0.2 microns and made from U16 ULPA filter paper. Viruses are smaller (0.004 to 0.1 microns), but the goal with virus filtration is to capture the particles that would host the virus. Aerosols particles are limited to 10 microns in size as coarse particles (over 10 μm) are liable to sedimentation and rapidly settle.

Q: Will these fit Israeli gas masks?

A: Yes they will.

Q: What exactly does "disposable, one-time use product" mean? If in home quarantined and Convid-19 was the concern, would I have to discard after each 1-2 hour trip out to get gas and supplies? Or is there a procedure I could follow to leave attached and reuse? A direct answer or reference to procedure is appreciated. Thanks

A: For safety, yes, you would have to discard after each use. You cannot decontaminate the inside of a filter, so after one use, it becomes toxic waste. When you come back home from a supply run, you would have to fully decontaminate and learn proper doffing procedure (the industry term for removal of personal protective equipment). As part of decontamination, you would dispose of the filter in accordance with local laws.

Q: Is it NIOSH approved?

A: No, it is not. However, this filter is compliant under European standards.

Q: Is it necessary to use more than one filter for ample protection? What is the difference between using one filter or two filters at a time? Why do the CM-6M gas masks come with 2 filter ports? I am generally unclear as to whether or not any of the individual filters you sell online work independently or if I am required to purchase two of each for adequate filtration.

A: The CM-6M and CM-7M masks could be used with one or two filters simultaneously. The benefit of using two at the same time is lower breathing resistance and more extended periods between swapping filters, but that comes at the expense of making the system more cumbersome. For that reason, we suggest using one filter at a time for most applications. Also, for tactical applications (using rifles), you have the option of attaching the filter on the left or right side, for left and right-handed shooters. This allows you to get closer to the stock of your firearm, as there is no filter in the way.

Q: How long can you store masks and an assortment of filters in a vehicle without worrying about the degrading of MIRA products? I live in 4 seasons area.

A: Storing MIRA products in a car is not recommended considering the fluctuation of temperature and humidity. If you commute with MIRA Safety products, we would suggest to bring them into your workplace during the day to avoid these fluctuations.

Q: Will these filters work for CA,OC,CS,CR PS & CN?

A: This filter is only intended to work with particulates, not riot control agents.

Since I don't have a decontamination shower how could I clean and remove my mask without getting contaminated?

A: Removing personal protective equipment is called "doffing". To properly decontaminate would require special training. Users of our products are responsible for acquiring all necessary training. There are many resources available online, but we suggest taking an in-person class to maximize safety and proficiency.

Q: Are these filters compatible with MIRA Safety CM-6M Tactical Gas Mask?

A: Yes, they are compatible with all MIRA Safety gas masks.

Q: How long can this be used before it needs to be replaced? Does one filter last a day or weeks etc? How do you know when to swap it? Thanks

A: Filter use time depends on atmospheric conditions, the concentration of particles, along with your breathing rate. You will know to swap the filter when it becomes harder to breathe. If this filter is used with viral particles, it can only be used once. If it is used with standard particles, it can be used and reused for an extended period of time (that period would be determined by the factors outlined).

Q: Once the filter is opened, how long will it last?

This filter does not contain activated carbon, so as long as you keep it in ideal storage conditions, it will last 20 years even if it's opened.

Q: Approximately how many hours/days will one filter last one person with continuous use?

That depends on a few factors, including atmospheric conditions, breathing rate, and particle concentration. For viral particles, this filter will last for as long as you can wear the mask. Keep in mind, filters are disposable one-time use products, and it's not safe to re-use a filter once it's come into contact with live agents.
