PEAK SERIES

HOW TO USE

Assemble. Attach the membrane microfilter to the gravity bag by first unscrewing the plug cap. Then screw the filter onto the outside of the neck cap, tightening until secure.
Attach Hose. Connect the included hose to the exposed outlet of the filter. Make sure the pinch clip is tightened to prevent water from flowing until you’re ready.
Fill. hen easy to use, unscrew the neck cap to expose the gravity bag opening. Fill with water, and retighten the cap to close. Note: there is no need to remove the pre-filter basket prior o filling up the gravity bag.
Set. To use as a gravity system, hang the reservoir to an anchor point using the strap to secure it.
Ready to Use. Release the pinch clip on the hose to allow filtered water to flow through, letting gravity do the work
Close filter. When finished, tighten the pinch clip on the hose to restrict water flow. This allows the hose to be removed from both connection points. Replace the plug cap on the membrane filter when a hose is not in use. Note: we recommend removing the gravity system from the hanging position to allow for raising the filter above the reservoir, preventing water from filtering out while the system is being secured.

Slow to star? Remove air bubbles trapped inside the filter by directly pulling water out through suction.
Backwash. 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 wasting 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 been fully pushed through the other side.
If storing your LifeStraw Peak Series 8L Gravity Water Filter System for greater than 1 month without use, we recommend following our long-term storage instructions to preserve the longevity of the filter and prevent clogging. For long-term storage instructions, visit www.lifestraw.com/howitworks

LONG-TERM STORAGE INSTRUCTIONS

Avoid drying out the filter by storing it with a saline solution made by mixing a teaspoon of salt with water. This will keep the filter at its highest performance and maintain the hydrophilic properties of the membrane, while also preventing any mold or algae from growing during long-term storage. When the membrane becomes completely dried out, it can be diﬀicult to get water to flow through again.
Follow these steps if you have already used the LifeStraw Peak Series filter and you plan to store it 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. These instructions can be found at www.lifestraw.com.
Immerse in Salt Solution. Using a reusable container dissolve 1 teaspoon of salt with 2 cups of water. Place the filter into the saline solution and use the backwash syringe to pull water fully into the filter. Place the filter into the reusable container, still filled with salt water, and seal tightly. Once the filter is removed from the system, the bag can be cleaned with household soap and water before setting out to dry.
Store. Store the container with the saltwater in a cool dry place. If storing the gravity bag, make sure the caps open before storage. If applicable, store your Peak Series Carbon filter Attachment System in a separate sealed container and keep it in a cool, dry place.
Resume Use. To use your Peak Series filter again, discard the salt solution and fill a cup or container with regular source water. Use the backwash syringe to remove residual salt water from the filter by pulling in the new water and pushing it back through the filter.

TIPS

Have trouble making sure the filter is secure? Fun fact! The handle of the plug cap can be used as a tool. Simply fit the loop-end around the filter, using it to screw the filter in the rest of the way.
Need some help re-inserting the pre-filter basket? We find it easiest to pinch the bag around the neck area while screwing in the basket. Push the cap toward the back of the bag and twist it using the finger tab, until it locks into place. You can give the pre-filter basket a gentle push forward and backward to ensure it’s locked into place.
Insertion is easiest when there is space between the back of the bag and the front cap, so we recommend holding the bag vertically when possible. Please avoid trying to re-insert the pre-filter basket while the gravity bag is lying flat, as this will be more diﬀicult.
Test your gear before you go! Follow the how-to-use instructions to make sure your LifeStraw Peak Series 8L Gravity Water Filter System is operating as you expect it to.
Slow flow rate? Use the backwash instructions to remove potential air bubbles in the membrane. Questions? Contact remy@lifestraw.com – we’re here to help!
