AquaSafeStraw compared to SeaPack

Introduction

SeaPack (Sea Pack) has range portable water forward osmosis devices www.Sea-Pack.com available for consumers.  The products use a filtration and sports syrup to purify water.  The units are designed for hiking, camping, sailing and emergency situations    

 AquaSafeCorp has the AquaSafeStraw specifically designed for travelling, hiking and disaster situations.  The only product that is safe for all to use, irrespective of health conditions.

For the purpose of the comparison, Life Pack, Sea Pack, Expedition, X-Pack, HydroWell2 Lifesaver Bottle will be used against the AquaSafeStraw.

Filtration Methods

The SeaPack (Sea-Pack) uses a membrane filter combined with a Sports Syrup to remove all viruses, bacteria and other substances to 3-5 Angstroms (0.3 -0.5 billionths of a meter, 0.0003 microns). 
The AquaSafeStraw uses a polyethylene membrane that filters down to 0.2 micron, exceeding the US CDC recommendation of 1 micron to effectively remove Giardia and Cryptosporidium.
