Having a few cases of bottled water on hand will help, but that may not be enough. In the event of a major disaster, finding water either for sale or otherwise may be next to impossible for perhaps days or weeks.
Without some way to obtain safe drinking water within about two days, the very survival of you and your family could be in question.
Your Solution: A gravity water filtration system
Purifies any fresh water source -- lake, stream, river, pond and rain water
Requires no electricity to operate, only gravity
Will produce clean, safe, great-tasting drinking water
Portable, in case you need to shelter outside your home
Filtering your water couldn't be easier -- just pour the water to be purified into the top portion of the system, let it slowly filter through the filter elements to the lower storage container and it will be purified and ready for drinking
Essentially all potential contaminants – organic & inorganic chemicals and pathogenic organisms – will be removed
Relatively inexpensive – well worth the price for your peace of mind
