Underground Survival Shelters Have Come A Long Way!

A far advancement from the days of old and prison-like boom or fallout shelters we have seen or read about in the past, the modern Underground Survival Shelters of today have grown in strength, capacity, and comfort to the point they have been converted to house the common comforts of home. Buried a minimum of 10 feet below the surface, and up to maximum depth of 42 feet, these type of shelters can provide safety and security from tornadoes to nuclear attacks. These shelters can be outfit with filtration and air-cleaning systems that protect the internal environment by shut off outside air supply, scrubbing and recirculating the air.
