Schwerkraft-Wasserfiltersystem der LifeStraw Peak-Serie mit sicherer Wasserspeicherung – 8 l + 8 l

The Peak Series membrane microfilter lasts up to 500 gallons (2,000 liters). This filter is designed to stop working (meaning water will no longer flow through) once it has reached the end of its lifetime.

Connecting to a reservoir - Peak Series Gravity System (3L & 8L)

1. Disconnect. Open the top cap of the LifeStraw Peak Series Collapsible Squeeze Bottle Water Filter System by unscrewing from the body. Remove the filter for use with the new system.  

2. Attach. Attach the filter to the LifeStraw Peak Series 3L Gravity Water Filter System by screwing the bottom onto the outside of the neck cap. To do so, make sure the plug cap is already removed from the gravity system. To attach the filter to the LifeStraw Peak Series Gravity Water Filter System - 8L, screw the bottom of the filter to the outside of the cap after first disconnecting the plug cap. 

3. Connect. Connect a hose to the end of the filter by attaching to the open end.

4. Ready to Use. Now that your filter and hose are connected, you can let water flow directly out of the filter using gravity. When finished, simply swap the hose out for a plug cap to close off the gravity system until later use. 

5. Backwash. When you are finished using, backwash your filter using the backwash syringe to remove excess water inside the filter. Close the caps. 

Connecting with the Peak Series Personal Water Filter Straw

1. Unscrew. Open the bottom cap of the LifeStraw Peak Series Personal Water Filter Straw by unscrewing from the body. 

2. Disassemble. Remove the filter from the Peak Series Collapsible Squeeze Bottle by unscrewing from the top cap. Remove the mouthpiece from the top cap and store somewhere secure. 

3. Connect. Attach your LifeStraw Peak Series Personal Water Filter Straw to the top cap by screwing bottom of the filter into the now open top cap where the mouthpiece sits. 

4. Fill. Open the neck cap of the squeeze bottle. Fill with water.

5. Ready to Use. Now that your LifeStraw Peak Series Personal Water Filter Straw is attached, you can drink directly from the collapsible squeeze bottle by pulling in water. 

6. Backwash. When you are finished using, blow air through the moutpiece to remove excess water inside the filter. Close the caps.

Follow these steps if you have already used your LifeStraw Peak Series filter and you plan to store for greater than 1 month without use. If storing for longer than 3 months, we recommend cleaning with a diluted bleach solution prior to storage for increased disinfection.

To disinfect, mix 1/4 teaspoon household bleach solution with 1-2 cups of water. Dip the filter into the bleach solution far enough so that the end is submerged in solution and use the backwash accessory (or blow into your filter if using your Peak Series personal water filter straw) to push and pull the solution from the filter several times. Rinse with tap water. For your squeeze bottles and gravity systems, we recommend cleaning all mouthpieces, caps, and parts for optimal disinfection. Don’t forget you can easily remove the mouthpiece on your squeeze bottles to get out the nitty gritty stuff and use the wide neck cap on the 8L gravity system to scrub the inside of the bag.

To store, mix 1 teaspoon of salt with 1-2 cups of water in a reusable container. Dip the filter into the saline solution and use the backwash accessory to push and pull water in and out of the filter. After a few rounds, put the filter into the reusable container filled with saline solution and seal tightly. Store in a clean, cool place. When ready to use again, use the backwash accessory with the filter (or backwash method with your straw filter) to push and pull tap water in and out of the filter, removing the salty water before resuming use. This will help prevent a salty taste.

Note: We recommend storing the bottle with a salt/saline solution because it helps to prevent any mold or algae from growing during long-term storage while also keeping the membrane microfilter wet which ensures a good flow rate when resuming use. When the membrane becomes completely dried out, it can be difficult to get the product flowing again.

Follow these steps if you have already used your LifeStraw Peak Series filter and plan to store it for longer than 3 months. If you’re planning to store for a shorter timeframe, we still recommend disinfecting your system, but at a minimum ask to rinse all parts and leave out to dry before putting away (make sure to check out our long term storage instructions!).

If your filter becomes clogged or you experience slow flow rate, we recommend backwashing the filter to remove excess debris from inside.Regularly backwash your filter after drinking to keep the filter clean and to prevent clogging. To do this, disconnect the membrane microfilter from the top cap by twisting counterclockwise. Then, screw the included backwash syringe onto the membrane microfilter. Plunge the open end of the filter into drinking water, and draw water up through the filter by pulling the syringe upward and away from the filter until it reaches the edge of the housing. Then push water back through the filter by pressing the syringe downward toward the filter until the water has fully been pushed through the other side.
