Most filters that we see in today's market are Ultrafiltration (UF) filters combined with a carbon block. If you are looking for a filter to protect you or your family from outdoor water source contaminants it must protect from Waterborne Viruses NOT just Bacteria, Parasites and the other usual contaminants.
In today's world of clever advertising, it is easy for companies to distract you from this fact. Our filter is as thorough as a filter can be, and our advice is clear, read the filter details before you purchase a filter bottle. Does the filter remove PFOA's, Viruses, Trace Pharmaceuticals, Endotoxins and Chemical reduction? If not, then you are at a very real risk of these contaminants that are present in our water sources, and they can make you seriously ill.
