emergency desalination filter system that rejects contaminants and
create pure drink. Purifiers use chemicals to try to kill pathogens and
therefore require long exposure times, high dosages and result in a
drink that may not be safe. SeaPack's emergency desalination membrane

failure. The primary risk is that bacteria introduced to the clean side
product through normal use (backwash or airborne) will eventually cause
bacterial growth within the clean side of the membrane. In the event of
emergency, the health risk from this growth is minimal due to the less
threatening nature of these type of bacteria, and certainly much less
alternative of not using the SeaPack product at all.
Is it possible for harmful bacteria to grow in the sugar-based
There is very little risk of this happening. Our nutrient driver is
to lower the pH of the drink to 3.2, which is inhospitable to
bacterial growth. In addition to this, the charge contains
sorbate and sodium benzoate, commonly used food preservatives to keep
microorganisms from growing.
How long can I store your products before they go bad?
When stored below 90F, we guarantee a 3 year shelf life. Membranes

Users are advised not to use leaking bags. The membrane itself is
rugged. The rejection side of the membrane filter does not come into
with abrasive material that could be present in the source water and
protected from damage. Any puncture of the membrane would also likely

sugars responsible for pulling water across the filter will seep into
water, preventing water transfer across the membrane and keeping the

Can the membrane tolerate high temperatures and freezing on
the low end?
The membrane handles extreme temperatures fairly well. During storage
membrane systems can tolerate temperatures from 40F to 160F.
160F will cause failure of the plastics. After initial start and during

Does the product meet
EPA standards require chemical purifiers to achieve 6-Log reduction of
