Combining cutting-edge ultra-low particulate air (ULPA) filtration with 40 mm standard NATO threading, these P3 certified biofilters work with your existing NBC/CBRN gas mask to provide unparalleled, long-lasting protection from airborne viral and bacterial threats. These filters are vastly superior to common half-face masks in practically every scenario. Please Note: This bundle comes with 6 filters in total. Key Features: 40 mm x 1/7” NATO filter standard (EN 148-1:1999) threading P3-certified protection (according to EN 143:2000 standards) filters out 99.9999+% of biothreats (not suitable for other CBRN threats) Lightweight (100g) construction Utilizes some of the highest quality ULPA filter construction that works on particles as small as 0.2 microns Prevents aerosol and airborne transmission of viral and bacterial threats 20-year shelf life for easy long-term storage Hydrophobic filter paper is ideal for decontamination showers Maximum Protection from Pandemic & Biological Threats Modern gas masks provide unparalleled protection from a wide variety of chemical, biological, radiological and nuclear threats. And now, with the new MIRA Safety ParticleMax P3 Filter, the same high-quality mask can protect you from bacterial and viral threats—including widespread pandemics like Ebola, coronavirus (including COVID-19) and H1N1. This effectively turns your ultra-secure CBRN gas mask into a full-face respirator with the highest level of protection from airborne threats. Unlike common surgical masks and half-face respirators, you’ll get a perfect seal and full-face protection for everything including the soft tissue around your eyes. Engineered using the latest in ULPA filtration technology, the same kind you’ll find in “clean rooms” where semiconductors are manufactured. These P3 filters meet some of the highest standards in practically every metric. They’re made using special filtration media and grade 16 filter paper, resulting in a MERV rating of 20 (the highest attainable for air filtration quality). ULPA filters at this level are handcrafted using specially made fiberglass material, then pushed through a rigorous quality control process to ensure consistent quality across each and every filter. They’ve also been subjected to extreme testing to ensure they’ll filter out any and almost all environmental biothreats. The filter is even hydrophobic, so you can wear your mask in a decontamination shower without compromising your safety. The end result? A filter and gas mask combo that’s practically impenetrable for almost all of the world’s biothreats. To infect you, viruses must enter your system through particulate or aerosol intrusion. Once you’ve got a perfect seal around your full face (possibly even reinforced with a full-body HAZ-SUIT), it is practically impossible for these threats to enter your body. NOTE: Due to their sophisticated and specialized construction, these filters will NOT provide protection from common CBRN threats and are primarily intended for protection from biological threats and airborne illnesses. We recommend keeping a variety of filters on hand to tackle whatever threat comes along. This product comes in a pack of six (6) sealed filters with a shelf life of 20 years. They’re designed for easy long-term storage and handling, with a single package of six filters providing a solid amount of protection for one user (though we recommend stocking a full 2-week supply, if possible).

The filters should be stored in their original packaging at temperatures from -58 to 122°F (-50 to +50°?) protected from the effects of precipitation and groundwater. Maximum humidity during storage of the filters is 98%. Storage in places other than those specified can affect shelf life. Shelf life expiration is specified on each filter. The shelf life of each filter is 20 years.
