Whether you’re using the filter for hiking, camping, or because of a natural disaster, you can be secure in the knowledge that the SurvFilter 300 will provide clean drinking water to keep you alive.
When water flows through the SurvFilter 300, there’s an ionic exchange that captures the viruses and bacteria so you get clean drinking water. (Imagine the filter is a magnet that extracts all of the bad stuff.)
To give you an idea of just how thorough the SurvFilter 300 is…
When water passes through the filter it has to make its way through approximately 400 layers of fibers and pores. (Below is a simple graphic that shows the hundreds of layers of ion-charged paper the water flows through.)
What’s more, the filter is infused with silver, which means it eliminates bacteria (and everything else) going through it so grit doesn’t build up and clog the filter.
Put another way…
All water filters are NOT created equal.
Most water filters are hollow fiber membrane filters such as the popular LifeStraw.
Hollow fiber filters don’t filter viruses and chemicals very well.
Hollow fiber filters are essentially made up of a bunch of tubes that can easily break. If you drop a hollow fiber filter or if it becomes frozen, it’s worthless. (The graphic below shows these tubes and how vulnerable these filters are.)
However, since the SurvFilter 300 uses nanotechnology you can throw it against a wall or put it in your freezer and it will still work since there are no tubes that can be broken.
What’s more, the SurvFilter 300 has been rigorously tested and certified by independent water laboratories (BSC Laboratories in Gainesville, FL, FL DOH Laboratory #E82924, EPA# FL01147) to remove bacteria, virus, Giardia and Cryptosporidium.
In other words, this filter has been tested and proven to remove 99.9999% of contaminants. (That’s why I was able to drink out of the trough at the livestock auction and the waste pond and not get sick.)

How does a person know when a replacement filter is needed?
They are good for 250 gallons of water. But since we don’t normally measure how much we drink (especially under dire circumstances) you’ll be able to tell if the filter needs to be replaced when it begins to get difficult to ‘suck’ water through the straw.
