Driving the Future of
Filtration
CUNO
Today & Tomorrow
CUNO Incorporated, a 3M company, is a world leader in the design,
manufacture, and marketing of filtration products for the separation,
clarification, and purification of fluids and gasses. Its products are widely
used throughout the global healthcare, industrial, and water markets to
make customers more successful.
A History of Ingenuity
The name Cuno comes from the Company’s founder, Charles Cuno, who
started the Company in 1912 in Meriden, Connecticut. The Company
began as a supplier of mechanical parts to the automobile industry but
began to develop metal and mechanical filters early in its existence.
During the 1960’s it turned its attention solely to filtration and developed
a line of resin bonded depth filters for the industrial market that are still in
production today. Progressing to finer and more sophisticated filtration,
CUNO’s engineers invented a cellulose based filter that was charge modified,
permitting the filtration of sub-micron particles, smaller than the pores of
the filter. Variations of this filter are used today in the blood fractionation
and biopharmaceutical industries. CUNO was a pioneer in the development
of microporous membranes, and the use of nylon 66 for the formation of
filtration membrane. Finally, leveraging the technology developed for the
industrial market over to the residential and commercial drinking water
market, the Company launched a full line of products under the Aqua-Pure®
brand name. CUNO’s unique carbon block process results in a product that
reduces a wide variety of chemical contaminants in water while delivering
high flow rates and low pressure drop.
In 2005 CUNO was acquired by 3M and now operates as a division within
the Industrial and Transportation Business. The acquisition combined
the innovation of 3M with the filtration application know-how of CUNO.
The combined entity participates in virtually all the key markets for
liquid filtration. CUNO has fully integrated into 3M’s international
organization capitalizing on the growing market for cleaner fluids in
industry and cleaner, better tasting water for people around the world.

Cleaner, clearer
Residential
The choice of the water professional.
CUNO has long been regarded as a leader in delivering quality filtration
products for a variety of residential applications. Maintaining a customer
focus has resulted in a complete line of water filtration and water treatment
products to provide families with cleaner, clearer water for home use, and
even some office and light industrial applications.
Our labs provide water testing free of charge to the end consumer to help
better identify the problems faced in each home. Then, our network of water
professionals have been trained to identify and install the best solution to
meet that specific need. Different parts of the country face different water
issues. For example, hard water is more predominant in Midwestern states
than on the east coast; municipal users face higher chlorine/chloramine
content than well users; and lead poses a threat in many communities.
water
Applications
Point-of-Use Systems filter the water for a specific use
or location, such as kitchen and bath. In the kitchen, our
undersink systems offer consumers customized filtration
solutions that address simple aesthetic issues such as
sediment and chlorine taste and odor to sophisticated
Reverse Osmosis systems that offer the highest level of
contaminant reduction. Drinking water systems typically
offer higher levels of filtration and the water is delivered
through a dedicated faucet. Other systems provide
filtration for all of the water at the sink, again with
varying levels of filtration.
All of these systems are installed out-of-sight, under the
sink, with only a faucet to potentially affect the décor of
the kitchen. To address higher end kitchens, we also offer
decorative faucets in a variety of finishes.
To further address water concerns in the kitchen, we offer
a series of in-line filtration products to filter the water for
refrigerator ice makers and water distributors.
In the bath, shower filter systems help protect from the
effects of breathing steamy chlorine fumes. In addition,
reducing the amount of chlorine in the water helps prevent
dry skin and hair. Undersink systems can also be installed
in the bath to filter the water at the sink.
In the basement, point-of-use scale inhibition cartridges
help protect water heaters.
At the office and in the kitchen, in-line and cooler systems
filter the drinking water in tankless water coolers,
drinking water faucets, and coffee machines.
Point-of-Entry Systems address all of the water entering
the home. Again, a variety of options address the specific
needs of each home.
Simple Filtration We offer filtration systems that address
sediment, as well as chlorine taste and odor, in all of the
water entering the home. We recently introduced a new
innovation: Sanitary Quick Change in a whole house
filter system. Gone is the cumbersome, time consuming
cartridge change experience. Just a quarter turn removes
the old cartridge. Another quarter turn installs the new.
The homeowner’s hands never touch the dirty filter media.
Water Treatment For more complex situations, we make
water treatment products that address heavy sediment
content, high acid content, arsenic, and lead, to name a few.
Other point-of-entry systems include water treatment
systems for commercial and light industrial applications
that are found in workplaces around the world.
Specialty Engineered Products CUNO also works with filter
integration for appliances and other private label solutions.

Applications
Recipe Quality Water™ Water is the main ingredient in
many recipes and beverages. As such, water affects the
quality, consistency and appearance of any product.
It may be pleasant to drink, but certain constituents in
the water can cause the end product to appear cloudy,
look oily, or taste differently from day to day.
For example, the consumption of specialty coffees,
coffee based beverages and specialty teas is on the rise.
Approximately 98% of coffee is water. Any off-taste
from chlorine can change the taste of the coffee, tea or
espresso, which can drive customers to seek a better
tasting location.
Filtration solutions for
Post-Mix machines present similar challenges. Excess
chlorine residual can cause unpleasant tasting beverages.
High turbidity can cause the beverages to appear cloudy
and unappealing.
Appearance is Everything When a customer sits down
to a meal, but the dishes and silverware are spotted with
hard water spots, it ruins the atmosphere. Warewashing
equipment can be protected by water softeners, which
will reduce the spotting on dishes, as well as helping to
protect the equipment itself.
Helps Protect Equipment Water can also affect the equipment
in which products are made: Sediment particles can clog
fine spray nozzles; chlorine and chlorine by-products
can cause corrosion; calcium and magnesium can form
hard scale on coffee brewer heating coils and evaporator
plates. Scale build-up also causes an increase in energy
consumption and a decrease in the efficiency of the
equipment.
Food
service
customers
around the globe
Installing equipment that helps protect water-using
equipment can lead to reduced service calls and reduced
downtime increase the bottom line profitability.
To address all of these issues, restaurants and convenience
stores use 3M Water Filtration Products to help improve
the quality of the water they use to cook with, as well as to
help protect their water-using equipment like coffee and
tea brewers, steamers, steam tables and ice machines.

Applications
Scientific Applications Support Services
(SASS)
Providing the key to customer collaboration, the global
CUNO SASS organization is a team of multi-disciplinary
scientists and engineers that provide the vital link between
CUNO’s filtration knowledge base and customer needs.
With complete access to CUNO technology and its research
and development, members of the SASS group provide
on-site bench-scale tests and assist with customer scale-up to
the full manufacturing process. When unique processing
requirements are encountered, SASS is expertly equipped
to identify filtration solutions using either the broad
array of existing CUNO filter products or by working
with CUNO R&D to design a custom solution for the
application.
Assisting with Regulatory Requirements CUNO understands
the exacting nature of the regulatory environment and
the demands on today’s pharmaceutical and bioprocess
industries. In response to these ever increasing demands,
SASS has developed a Validation Support Services program
designed to streamline filter regulatory compliance. These
services extend beyond the validation of sterilizing
grade membrane filters to the support and validation
of prefilters. CUNO helped pioneer prefilter validation,
an emerging industry trend, with our Zeta Plus line of
pharmaceutical grade prefilters.
Filter Integrity Testing Water-wet integrity test values
are supplied with all sterilizing grade CUNO membrane
filters. However, many filtration applications are in
solutions other than water. The properties of these
solutions (surface tension, wetting angle, etc.) may alter
the integrity test value of the filter under consideration.
SASS can execute the appropriate method to determine
the fluid specific integrity test parameters to answer this
critical question.
Bacterial Retention This evaluation supports the ability of
a given filter to quantitatively retain a test organism when
maximally challenged. The appropriate test organism is
typically suspended in the drug product or fluid of choice,
at a concentration that will yield a complete “challenge”
to all areas of the membrane’s surface.
Chemical Compatibility Testing This evaluation provides
evidence that the CUNO filter selected for the particular
application is chemically and physically compatible with
the fluid to be filtered, as well as the operating conditions
in which the filter is expected to perform.
Extractable Testing Evaluation of what is extracted from
the filter materials is critical in many applications. After
all, it is important to understand what a filter can add
to a process as well as what it can remove. The testing,
in the customers’ specific fluid, is used to identify the
material and amount extracted. Additionally, SASS
can recommend the appropriate filter combinations to
reduce the number of extractable components to simplify
validation issues.
CUNO Filtration Technologies
CUNO’s core technologies, filtration media and delivery
systems, provide solutions for filtration challenges in a
wide range of applications. From cost effective, coarse
filtration using filter bags, to the finest particle removal
using hollow-fibers, our customers depend on CUNO
to develop solutions.
Depth Media Utilizing various platforms, CUNO provides
depth filtration products in a variety of forms. Rigid
cylindrical elements, such as the Micro-Klean™ product
family, are manufactured to meet the requirements of a
range of applications. These filters are usually constructed
using either resin or thermal bonded fibers, or are multi-
layer, spiral wrapped design, to provide cost effective
particle retention to industry and consumers alike. The
Zeta Plus family of filters uses a unique felting process to
create a depth filter pad which is delivered to customers
in sheet, cartridge, and capsule formats.
Prefiltration Pleated Membranes Available in materials
from non-woven polypropylene to cast nylon and
polyethersulfone, these filters provide the filtration
surface area required to retain large amounts of unwanted
material, usually in the micron or submicron size range.
Typically, prefilters are used to protect final sterilizing
membranes, reverse osmosis membranes, or other
downstream equipment and processes.
Sterilizing and Diagnostic Membranes These cast
membranes with absolute removal ratings of 0.20 microns,
the size required to retain bacteria, are used extensively
in the pharmaceutical and other healthcare or food &
beverage processing/manufacturing. In fact, CUNO
is constantly collaborating with industry leading drug
researchers to provide the necessary filtration solution
as early as possible in the pharmaceutical development
process. Diagnostic membranes, used in devices to test
for specific medical conditions including pregnancy and
blood sugar, are finding even more applications in medical
testing as advances technology (gene identification and
biotechnology) move forward by leaps and bounds.
Metal Filters and Filter Housings CUNO’s engineering
experience in metal goods is extensive. The first to offer
metal edge type filters, where the space between two metal
surfaces determines the degree of filtration, CUNO has
offered this method of retaining particles contaminating
fluids for over 50 years – in fact, some of the earliest
installations are still in operation. This expertise extends
to the design and manufacture of a wide range of pressure
vessels to house the filter elements. From single cartridge
housings with flow rates of 28 gallons per minute, to large
industrial housings featuring flow rates measured in the
thousands of gallons per minute, CUNO can provide
vessels capable of exceeding even the most stringent
customer requirements.
Filter Systems Combining both filter media and housings
in an innovative way, a fusion of media and housing design,
has produced filter systems used in diverse applications.
CUNO’s High Flow Filter system utilizes a filter element –
capable of fluid flow in excess of 150 gallons per minute
through a single element – and a smaller than typical filter
housing to provide a solution for customers having high
volume filtration requirements and critically limited space,
such as off-shore oil rigs. Other customers, such as global
food service outlets, use CUNO filter systems for their ease
of use and the water quality consistency so that the cup of
coffee made in a diner in New York tastes the same as the
one made in Tokyo.
