ALPINESURVIVAL.COM — This NOS filter is commonly used in Class 10 and Higher clean rooms,
to filter particulate radiological, biological agents, smoke, and other hazardous materials.

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, and 12 inches deep.


Simply have your AC/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 greatly provide additional security.


These filters were planned for use in Washington Public Power Supply (WPPS) Nuclear Power Plants.

Survival NOS HEPA Filters
24" x 24" x 12"


Tape and Plastic over windows and doors is a dangerous 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 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 secure ALL your Survival supplies is now!
It will be too late to start shopping for supplies once we have been attacked.
Dateline 1/12/13: Gun sales and prices have doubled, and NO ammunition is available.


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.
Despite that, the government advises sealing up a 'safe room' with duct tape and plastic sheeting.

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.
NOW 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!

News Flash 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.

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 shut down and Alpine acquired many of the New Old Stock (NOS) filters.

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.

Using a conventional furnace filter as a pre-filter will increase the lifespan and efficiency of your HEPA filter that is designed for filtering down to 0.3 microns. That includes radiological particulates (Japan), biological, chemical, etceteras.

Don’t pay $750.00 to $1,200.00 + shipping & handling for a civilian-type filter when you can buy this superior NOS Nuclear Power Plant filters and save! Filters designed to protect personnel at American Nuclear Power plants. Yes, you get the same identical filter, in fact the very same filter.

When we experience a Nuclear Biological or Chemical attack, or a Chemical and Biological attack on American soil, you will be relieved that you had the foresight to protect your family by preparing for the unthinkable. With a little preparation, and a dose of American ingenuity, your family and friends can survive many forms of unconventional warfare. Please don’t entertain the notion that it would be better to die in the initial attack than to survive and witness great misery. If Americans believe that, we WILL be defeated!
