Efficiency Prefilter

Our Pre-Filter is a rigid and durable surface filter which utilizes an advanced synthetic media.  It offers superior particulate contact resistance as your first line of defense from a dirty bomb or atomic bomb dust.  Its primary purpose is to filter the larger particles from all incoming air.  This four layer filter with progressive density significantly increases particulate holding capacity. As a highly efficient 85% pre-filter, it will greatly extend the life of the High Efficiency Filter.

Filter Science feels very strongly that nothing else manufactured today will do the job.  When you buy an NBC filter, even if you don buy it from us, please make sure you are buying ASZM Teda Carbon which has been tested and approved by the U.S. Government Department of Defense.  Many supposed NBC filters on the market today utilize common carbon which is 10% of the cost and will be very ineffective in case of an emergency.   

Our chemical warfare, chemical weapons filter is a massive block of a very specialized and technical, activated carbon 14 inches wide, 18 inches tall and surrounded by a heavy, corrosion proof, non-ferrous metal frame.*  It's inner construction and faceplates are all 16 or 20 gauge 304 Stainless Steel.  It massive size and weight assures your safety.  It utilizes the only carbon manufactured today which was developed in conjunction with, and approved by the U.S. Government Department of Defense for Military Ventilation Systems in Control and Command Centers, Military Vehicles, and Aircraft.  These activated carbons were specifically designed to remove deadly toxins such as advanced chemical weapons, modern chemical warfare agents and 21^st. Century nerve agents.  It also is the same patented carbon used on the air supply for the M1A2 Abrams Battle Tank.  While primarily designed to nutralize deadly chemcial weapons, the extreamly small pores in the carbon can also trap dirty bomb and atomic bomb dust.

Our Nuclear Grade, Particulate Air Filter utilizes the same material and technology developed for, and used to support the U.S. Government Apache Longbow Helicopter and M1A2 Abrams Main Battle Tank. We believe it is the most advanced filter on the market today for atomic bomb or dirty bomb dust, and/or biological weapon agents. 

This filter is a 4.75 inch thick Nuclear Grade, High Density, High Efficiency, Particulate Air Filter.  It will filter the incoming air far cleaner than a standard HEPA filter 10-inches deep.  It is primarily used in nuclear power generating facilities and biological research laboratories where the highest degree of clean air is absolutely mandatory.  Before each Nuclear Grade, Particulate Air Filter is shipped from our plant, it has been tested to retain all particles to 0.12 um in size and at an efficiency rating of 99.999%, far cleaner than a standard Hepa which is 99.97% on a much larger particle size of 0.30 micrometer particles.  Example: The air you breathe usually contains 50,000 contaminant particles per square foot (which is average in the U.S.).  This filter is designed to reduce that amount to a few sub-micron particles per square foot.
