Micron ratings are only applicable when used to rate membrane filters where there is a defined pore and it can be measured or verified using a standardized test.  Since not all water filters are membrane filters, the micron rating can be misleading.   More important than a pore size rating is what the filter has been certified to remove from the water.  We believe that “Certification” is the only way that a filter should be rated and advertised.  For this reason Aquamira Filters are CERTIFIED as follows:

Filter Straws – 99.9% of Protozoa

Green Line Filters – 99.9% of Protozoa; 99.99% of Bacteria

Red Line Filters – 99.9% of Protozoa; 99.99% of Viruses; 99.9999% of Bacteria

Proof of certification is available on www.aquamira.com


Rather than a mechanical filter media, the Red Line (virus removal) filter removes submicron contaminants through electroadhesion and ion exchange.  The crystal structure allows for an extremely high surface area and a large number of active sites creating a tortuous path for viruses and other contaminant removal.  This media has unique benefits:  High flow; Low pressure drop; and Submicron retention.
