REQUIREMENTS FOR USE
WATER PRESSURE REQUIREMENTS:
LifeStraw Max is powered by water pressure from existing piped water
systems. The minimum recommended pressure is 1 bar / 14.5 PSI. Below
this pressure, the ow rate will be aected.
Maximum pressure: 6 Bar / 87 PSI
HOSE ADAPTER:
The LifeStraw Max includes a
pre-installed hose adapter at the
water inlet for use with standard
U.S. hoses (3/4” MGHT). If
using with a hose of dierent
threading, please remove the
pre-installed hose adapter.
The inlet will become 3/4” BSP
compatible.
CARBON FILTER:
In order to preserve the longevity
of the lter, do not remove
LifeStraw Max advanced carbon
lter from sealed packaging until
ready to use. When removing the
LifeStraw Max advanced carbon
lter from its separate packaging,
please handle carefully to avoid
any damage. Top lid must be in
place when using LifeStraw Max.

FIRST TIME USE
CONNECT SOURCE WATER HOSE
Connect the source water hose (3/4” MGHT) to the
water inlet by screwing BOTH sides of the inlet adapter
tightly.

Blue drinking water dial
in open position
Switch the dark gray backwash dial to position 1 and wait
30 seconds. Then turn it to position 2, wait 30 seconds,
and continue to do so until reaching position 0. Let the
water run for up to 2 minutes while in position 0; Discard
the rst batch of water.
Note: if water is extremely muddy, cycle through backwash procedure
a second time. If you notice a “sweet” taste after performing the
backwash procedure, cycle through again.
LIFESTRAW MAX IS NOW READY TO USE
With the backwash dial in “0” position and the drinking water dial on,
the LifeStraw Max is ready to use. Simply turn the drinking water dial to
the “close” position when done using. The system does have a pressure
regulator, but it is advisable to turn o water source when not in use for a
longer period of time.

Note: If using a dierent hose, unscrew the included adapter to
connect the source water hose (3/4” BSP).
CONNECT BACKWASH HOSE
Connect the included light gray backwash hose to the
orange backwash outlet and route to an area where
dirty water can be discarded.
CAUTION: DO NOT DRINK WATER FROM THE
BACKWASH HOSE
TURN ON WATER
Turn on the water source. Make sure the preassure is
greater than 1 bar, then rotate the blue drinking water
dial to the open position.

9
Ensure all hose connections, lter cartridges, and pre-lter lid are in place,
as any loose parts may cause leaking. Make sure the dark gray backwash
dial is in position 0.
EVERYDAY USE
Water will start to ow from tap once the
blue drinking water dial is rotated to “open”.

2TURN ON WATER SOURCE (HOSE)
3ROTATE BLUE DRINKING WATER

4TURN OFF WATER SOURCE (HOSE) WHEN FINISHED
SWITCH BLUE DRINKING WATER DIAL TO CLOSE POSITION
Once nished and water source is shut o, switch blue drinking dial to the
“close” position.
NOTE: Once the dial is CLOSED, it may take a few seconds for water to stop owing. Make sure
the internal hoses are emptied of water as much as possible.
5
Do not remove the lid if the system is
on and the hose is connected to the
inlet. Opening the lid while the system
is under pressure could result in
damage to the product or injury.
The lid can ONLY be removed when the
system is o and the source water hose
is disconnected from the water inlet.
CAUTION!

10
Tip: Refer to Backwash Procedure when you see a reduction in ow rate
during use.
CLEANING | BACKWASH PROCEDURE
TURN ON WATER SOURCE (HOSE) AND TURN BLUE DIAL TO OPEN
POSITION (Water should be owing from the tap)
Let the water run for up to 2 minutes while in position 0. Discard the
water until completed.
Note: if water is extremely muddy, cycle through backwash procedure a second time.
NOW READY TO RESUME USE Turn o water source when nished.
WHEN TO BACKWASH
• Once a day or when you see a reduction in ow rate
• After pre-lter cleaning
• After any cartridge or lter replacement
• After long periods of non-use

Switch the dark gray backwash dial to
position 1 and wait 30 seconds. Then turn it to
position 2, wait 30 seconds, and continue to
do so until reaching position 0.
ROTATE GRAY BACKWASH DIAL TO EACH POSITION FOR 30
SECONDS
3LET WATER FLOW FROM TAP FOR UP TO 2 MINS AND DISCARD
Regular backwashing ushes out contaminants from the lter cartridges and
helps to maintain ow rate.
4
NOTE: Once you begin the backwash process, water will stop ow-
ing from the tap. This is normal. During dierent rotations, water
will ow out of the backwash hose. Once the dial is returned to
position 0, water will resume owing from the tap.
WARNING: Never consume water from the backwash outlet. It is
not safe to drink.

NOTE: If is not required to remove the top lid in order
to pull out the pre-lter. However, If you have diculty
removing the pre-lter while the top lid is closed,
slide the lid locks inward to remove the top lid before
twisting o the blue pre-lter lid.
CLEANING | PRE-FILTER
If your water is clear, we recommend cleaning the pre-lter weekly with regular
use. If your water is cloudy, you may need to clean the pre-lter more frequently.

lter, disconnect the white lter housing bridge. Unscrew the light
gray carbon lter housing cap and remove the carbon block inside.
Set aside to dry.
PLACE CARBON BLOCK IN SEALED BAG
Once the carbon block is dry, place in a sealed bag for storage to
preserve the longevity of the lter. The light gray lter housing
should remain inside the Max with the cap reattached.

TROUBLESHOOTING
LEAKING
Follow the below checklist if you experience leaking with your Max.
• Ensure all hoses are tightly connected and there are no holes in
each hose
• Ensure the white lter housing bridge is fully connected with push
tabs clicked in place
• Ensure gray cap of carbon lter housing is tightly screwed on
• Ensure carbon lter block is properly installed with black silicone seal
facing the top
• Ensure all three lter cartridges are properly installed into both top
and bottom connectors
If you continue to experience leaking, please contact LifeStraw at info@
lifestraw.com.
LOW FLOW RATE/CLOGGING
If you experience low ow rate or clogging, follow the below procedures.
• Open the lid and ensure none of the hoses are kinked
• Perform backwash procedure. If water is extremely muddly, run
through cycle twice
• Using instructions provided, clean pre-lter.
If you continue to experience little to no ow-rate, it may be time to
replace your membrane ultralter set. Water will stop owing through
once the membrane ultralter set has reached the end of its lifecycle.
