How do I replace the carbon filter for my LifeStraw Max?In order to preserve the longevity of the filter, do not remove LifeStraw Max advanced carbon filter from sealed packaging until ready to use. When removing the LifeStraw Max advanced carbon filter from its separate packaging, please handle carefully to avoid any damage. Top lid must be in place when using LifeStraw Max.
1. REMOVE TOP LID
Slide the LifeStraw Max lid locks towards the middle of the unit to unlock. Lift the lid off of the Max and set to the side. Lid locks do not need to be held together while lifting the lid.
2. DISCONNECT WHITE FILTER HOUSING BRIDGE
Disconnect the top filter housing bridge (white) from the filter cartridges by pushing the two tabs toward the center of the box while pulling the white housing bridge upwards.
3. UNSCREW AND OPEN THE TOP OF THE ADVANCED CARBON FILTER HOUSING (GRAY)
Unscrew the top cap of the gray carbon filter housing. Locate the carbon filter block and remove from wrapping.
4. INSERT CARBON BLOCK WITH BLACK O-RING ON TOP
Place the carbon filter, with the black silicone ring facing outward, into the gray carbon filter housing. Screw the gray carbon cartridge lid on tightly.
5. REASSEMBLE CARBON FILTER HOUSING
Make sure that the bottom of the gray carbon filter housing is in place by pressing firmly into the fitting. Double check that the side cartridge connectors are firmly in place with the black seal flush against the inside.
NOTE: If you removed the carbon filter housing from the Max to insert the carbon block, reinsert by fitting the bottom of the cartridge into the plug fitting located in the bottom of the Max. Ensure the two side connectors are lined up to their matching pieces and press firmly to make sure they are in place.
6. RECONNECT WHITE FILTER HOUSING BRIDGE
Reconnect the top filter housing bridge by lining up the tabs with their associated slots and pressing down until it clicks into place, indicating it is fully locked.
7. CLOSE TOP LID
Place the top lid back onto the top of box, sliding the lid locks toward the corners to secure.
If you are having difficulty opening the carbon filter housing, we recommend pulling the full gray carbon cartridge out of the Max to unscrew the top and install the carbon filter block.
