PLEASE NOTE BEFORE INSTALLATION
The Alb Filter® DUO has a standard M22 female thread, suitable
for most taps with M22 male thread. If your faucet does not
have a M22 external thread, you will need an adapter.
Adapter available at www.alb-filter.com
Shop Category: Accessories
DETERMINE CONNECTION THREAD
The two most common jet control variants are called M22 or
M24 in technical terms. Furthermore there are further sizes
e.g. M16, M18 and M21, which are however less common.
Online thread guide for more details at
www.alb-filter.com
Procedure for determining their connection thread:
1. Remove your aerator from the fiing. If necessary, use a
pipe wrench with jaw protection or a mounting key.
2. Measure the diameter of the thread on the tap.
Alternatively, measure the diameter at the unscrewed
aerator.

thread, screw the previously determined thread adapter
into your armature. (C)
If you have any questions about the thread adapters, you
can contact us using the contact details on our website.

1. Check that the Alb Filter® DUO is correctly and firmly
aached to your faucet. If necessary, use a pair of pliers
with jaw protection to tighten the union slightly.
2. Before opening the water inlet of your faucet, make sure
that the switch lever is in vertical (downward) position.
Mode: Unfiltered.
3. Set the switch lever to horizontal position (Mode:
Filtered) (E). Then slowly open the water inlet of your
faucet. (F)
4. Now let the water run through the water filter for 5
minutes to activate it. (G)
Production-related activated carbon dust may dissolve
during rinsing and slightly cloud the water during the
cartridge activation process.
5. Check the water filter housing and all connected
components for leaks. (H)
6. The Alb Filter® DUO is now ready for use.
We recommend to mount the Alb Filter® DUO on the
right side or aligned to the front to make the switchover
function (filtered/unfiltered) easier to operate.

8. Now let the water run through the water filter for 5
minutes to activate it. (G)
Production-related activated carbon dust may dissolve
during rinsing and slightly cloud the water during the
cartridge activation process.

MAINTENANCE AND CARE
The Alb Filter® DUO is generally low maintenance.
However, the maximum service life of the filter cartridges
must be observed.
Clean and lime-free fittings are the prerequisite for hygie-
nically perfect drinking water.
To remove limescale, we recommend the use of a vinegar
cleaner
Depending on the water quality, it may be necessary to
remove any deposits that have formed inside the housing
with a cloth (e.g. kitchen towel) every two months.
In case of calcareous water (>15°dH) and very frequent
operation, the changeover valve in the changeover lever
(6) may be damaged under certain circumstances. In this
case the bypass can be replaced. (Available under the
store category: Accessories)
FILTER CARTRIDGES FOR THE
ALB FILTER® DUO

CARTRIDGE REPLACEMENT INTERVAL
We recommend changing the filter cartridges every four
to six months (according to DIN 1988). They should also
be replaced after longer periods of standing (> 6 weeks).
Warranty claims are void if these instructions are not
observed.
Please dispose of used filter cartridges in residual waste.

GENERAL SAFETY INFORMATIONS
• No liability will be accepted for any damage caused by improper
installation.
• Maximum operating temperature: 45 degrees.
• Protect from frost.
• Do not use on a faucet with a pull-out shower.
• The cartridge should be changed aer 4-6 months. However,
note the replacement interval of the cartridges used individually.
• Earlier replacement may be necessary if the water flow is visibly
reduced, or if the water quality deteriorates.
• An early change is not a defect of the cartridge used, but an
indication of increased occurrence of fine particles or pollutants
in the unfiltered water.
• In exceptional cases, when the water in the supply line is very
cold (for physical reasons) condensation water may form on the
filter housing.
• To ensure complete safety with regard to the quality of your
filtered water, a water test in a competent laboratory is
mandatory.
• In connection with pressureless boilers, please note that due
to the high fineness of the cartridge, a pressure is built up in
front of it (approximately equal to the mains pressure), which is
reduced only slowly. Under certain circumstances, this can lead
to damage to the non-pressure-resistant boiler. Please contact
your responsible installer for this.
• No liability can be accepted for the consequences of using filter
cartridges from other manufacturers. We strongly recommend
the use of original Alb filter cartridges.
• Caution: In accordance with applicable regulations, never opera-
te the water filter on the drinking water network without a sys-
tem separator. Make sure that the connection of your domestic
waterworks, on which the water filter is operated, is equipped
with a system separator according to EN 12729 type BA. Water
that has flowed through a system separator is no longer consi-
dered drinking water.
• Please observe the applicable drinking water regulations of your
respective country before installation and commissioning.
• Use only with drinking water.

FAQ - FREQUENTLY ASKED QUESTIONS
F What does the NANO cartridge filter?
A The NANO cartridge filters only germs and bacteria down
to a size of 0.1 μm. This corresponds to 99.9999% (log6) of
microorganisms harmful to humans.
F Can activated carbon germinate?
A Yes. Please pay aention to the specified service life of the
cartridges.
F Does the activated carbon filter lime?
A No, the Alb Filter® is not explicitly a lime filter - it filters
bound lime flakes, but not dissolved calcium carbonate.
F Is the water safe to drink in Germany?
A The tap water provided by water suppliers in Germany is
treated in a complex process. Aer treatment, it complies
with the German Drinking Water Ordinance (TrinkwV).
However, the variety of substances that can be dissolved in
water is enormous. It is estimated that more than 50,000
dierent chemical compounds are present in water. Only a
few of these are filtered by water suppliers as standard.
F When does the filter need to be changed?
A The ACTIVE and ACTIVE PLUS+ cartridges should be changed
aer 4 months at the latest, the NANO cartridge aer 6 months
- at a consumption of approx. 150 l/week. If the flow rate of the
cartridge decreases prematurely, this may be due to poor input
water quality.
F What are signs that a filter change is necessary?
NANO: The water flow is greatly reduced or no water is coming
through at all.
ACTIVE, ACTIVE Plus+: The flow rate decreases only in rare cases.
Therefore, it is important to change the cartridges at regular
intervals, at the latest aer 4 months or 3,000 l of water flow.
F How high must the eective water pressure be to operate the
filters?
A For a good flow, the pressure should be between 2.3 and 2.6
bar for all cartridges. With the NANO cartridge, 1 bar is already
sucient for a good flow. The average water pressure in German
households is between 3 and 4 bar.
