Seal – 4 Pack
Use one filter in fresh or salt water? Yes, you can.
Based on reliable forward osmosis technology, the extraordinary Seal filter is both simple to use and exceptionally reliable, able to filter virtually any available water without clogging.
To use, simply place the pouches in the water source. In open water where the pouches might float away, use the provided net and tether to lire-raft or other object.
The Seal will swell over time as water flows through the membrane wall into the pouch. Salts and biological contaminants are blocked by the 0.0007 micron membrane filter.
When finished, simply poke with the included straw and drink.
Now you can rely on one filter to generate a safe drink using one filter, no matter where in the world you are.
