This HEPA Filter by itself filters the finest particles down to 0.3 microns, and greatly exceeds the performance of M-95 type filters, and military M-95 gas masks.   Fits standard 24-inch plenum ducting Or simply install a  24-inch plenum HEPA Filters to 0.3 microns This filter is commonly used in Class 10 and higher clean rooms, to filter biological agents, particulate, smoke, and other hazardous materials. These are U.S. Government NOS (New Old Stock) filters boxed in their original govt. packaging, including manuals. The cost savings is substantial. This HEPA Filter by itself filters the finest particles down to 0.3 microns, and greatly exceeds the performance of paper-type filters. In fact they exceed the filtering capability of M-95 gas masks. These HEPA filters are two feet by two feet square. They are 12 inches deep, and their pre-filters are 6 inches deep. A full two feet X 18 inches thick, of HEPA filter protection. Simply have your Heating company fit these filters to your 24-inch ducting to bring in HEPA Filtered air from outside your home. This creates a positive pressure inside your home, greatly helping keep hazardous particulates to 0.3 microns, ...outside your home or office! Many newer homes already have "outside air intake" central heating and cooling systems that create a positive pressure (plenum) inside the home. Fitting these HEPA filters to your existing central system would provide additional security.         HEPA FILTER 24 x 24 x 12 Weight 52 lbs  $195 each  The full set for $270     HEPA PRE-FILTER 24 x 24 x 6 Weight 29 lbs  $95 each  The full set for $270 You do not need the Pre-filter, but it is recommended     Specifications: HEPA FILTER 24" x 24" x 12" NOS  U.S. GOVERNMENT HEPA FILTER Tape and Plastic over windows and doors is a false security! Indeed, what happens when everyone in your little sealed up room runs out of oxygen? Everyone asphyxiates on carbon dioxide and suffocates, ...that's what!  -Read on... Americans are coming to realize  that we live in perilous times. We have enemies around the globe that would love nothing more than to bring the “great Satan to its knees”. Not only is North Korea rattling a nuclear saber, the CIA now admits their Taepo Dong II puts our west coast at risk!. American airborne troops (usually the last to be deployed prior to a military strike) are currently being deployed to the Middle East in final preparation for war. Our territorial borders are not secure and sleeper cells of suicide terrorists are on American soil planning their attack as you read this. Sadly, the United States government is woefully unprepared when it comes to protecting its citizens. While other countries (Sweden, Israel, etc.) have gone to great lengths to provide protective masks and safe room equipment for each of its citizens, our government contingency plans are limited to dealing with mass casualties. We need to realize that if Americans are to survive a nuclear or biological attack, we must take responsibility for ourselves and prepare in advance. The time to gather your supplies is now! It will be too late to start shopping for supplies once we have been attacked. Since the infamous attack on the World Trade Center, many citizens have demonstrated personal responsibility by purchasing gas masks and suits. These items are our first line of defense and will be invaluable for evacuation of a small area after a limited attack. However, if you live in a populated area where large numbers of people are trying to escape (which is a more likely target), evacuation will likely be paralyzed by gridlock. If you are successful in leaving your area, you might find that your destination has become contaminated by wind borne fallout, or is occupied by infected people, who also escaped! However, the most likely scenario involves government quarantine of affected areas. This means that you will be forced to stay put and ride out the storm. Gas masks and chemical suits are not only uncomfortable, they are eventually going to fail! Any person using common sense must conclude that you must escape to an uncontaminated area where you can eat, drink, cook, sleep and perform natural bodily functions! At a minimum, what you need is a clean room to which you can escape. Better yet, you might be able to protect your entire home, which would provide you and your loved ones with a safe, familiar living environment. The government is beginning to inform the public on how to protect themselves but the information they have provided is incomplete. Our children know not to put their heads in plastic bags. Considering that, have you heard any warnings from the government on the dangers of sealing yourself in a room with duct tape and plastic? Put a 55-gallon plastic yard-bag over your head and see how long you last before gasping for air. Calculate the volume of a 55-gallon container, divide it into the volume of your SEALED room, divided by the number of people, ...and see how long you will last!   Think about it! Duct tape and plastic is a good method for suicide! You MUST have ventilation in a sealed room or you will suffocate! But before that happens, you will loose consciousness from carbon dioxide inhalation, you will get drowsy and fall asleep, ...and then you will quietly die. That is unless someone manages to stay conscious and drags you outside into the biological and chemical agents that will have, by then, settled all around your house, ...and so you die anyway. For that simple reason, you at least need a Gas Mask to help get you to a safe zone.   Using a HEPA (High Efficiency Particulate Air) filter, you can construct an air filtration and ventilation system that will remove particles down to 0.3 microns in size. This would remove nuclear fallout, a wide variety of biological weapons and most allergens! Simply construct sealed ducting (using sheet metal or plywood) to attach the filter to a blower fan. Use the blower fan to draw outside air through the HEPA filter into your clean room, home or workplace. Such an air filtration system will provide you with highly filtered air, which will create a slight positive pressure within your living area. The positive pressure will help to keep airborne contaminants outside! You’ll want a large filter capable of enduring a dusty environment (nuclear detonations create a lot of dust). Our industrial size HEPA filter is NOS (new old stock) in the original unopened box. It was made in the USA by Mine Safety Appliance, the leader in industrial safety products. This filter was originally purchased by the United States Government for use in the unfinished WPPS Nuclear Power Plant. Due to budget overruns, the project was abandoned and the materials were sold as New Old Stock (NOS). It was another HUGE waste of taxpayer money, but you can still personally benefit from this case of government waste. Don’t make the mistake of choosing a small household HEPA type filter. When you need it, you will want a filter that is capable of working in severe conditions.   HEPA Filter Specifications: Mine Safety Appliance Company Ultra Aire® (MSA - P/N 463561) Size - 24"x24"x11-1/2" nominal Frame - 14 gauge cadmium plated steel with return bend on all four sides of both ends Separators - .0015" thick aluminum Media - per MIL-F51079B as called out under MUL-F51068D Face guards on both faces - 23 gauge - 4x4 mesh hardware cloth Adhesive - rubber base per MIL-F51068D Gaskets - 1/4" thick x 5/8" wide - sponge neoprene - Grade SCE 43 or 44 Filter media will be all glass with a maximum 5% binder and it is waterproof.

The Bonneville power administration advised everyone over 20 years ago that there would be a major power shortage coming and acting on those concerns were instrumental in trying to get some significant and new power generation on line. In the early 1980s, Washington Public Power Supply Systems was formed by several public utility districts and private utilities which were instrumental in trying to construct five nuclear plants. That resulted in the completion of one plant, the mothballing of another, and the scrapping of the other three because of the negative media criticisms of nuclear power resulting from Three Mile Island and the Chernobyl incidents. That resulted in the default of billions of dollars in bonds for a variety of reasons in the late 80's, which further resulted in a financial disaster on which many are still paying. The principal reason for the projects’ failure was adverse publicity from the Three Mile Island and Chernobyl incidents that had no similarities to these proposed plants under construction at the time, and were of a totally different design using state of the art technology. In addition, increased construction cost because of a lack of consistent safety standards from the Nuclear Regulatory Commission and increased interest rates coupled with labor strikes escalated the original construction cost. The other component of this was a vigorous construction schedule that had all five nuclear plants in different phases of construction simultaneously. That complicated the financial picture, as there was no money being paid out from generation over a long construction timeline. In retrospect, if one or two plants had been in construction at any one time and the completed one or two nuclear plants generating revenues paying back on the bonds and construction costs, would have resulted in a better financial plan that would have ultimately led to all five nuclear power plants’ successful completion. The result of all of this was that nuclear energy got a bad name and became unpopular for many that were involved in the construction program.
