Camfil Farr’s new mobile lab and
exhibition is now wheeling around
highways and major cities
in Central and Southern
Europe, the British Isles
and Scandinavia. The trailer
truck could be in your area
right now, and if you haven’t
seen it yet, it will be hard
to miss when you do. This
unique 16-metre-long “roll-
ing exhibit” is an impressive
sight. The message displayed
on the trailer is even more
striking. It boldly asks if clean
air should be a human right.
Do people have a right
to clean air? We think so.
Clean air is one of the
most essential prod-
ucts on the planet and
we deliver it all over the world, along with value to
our customers.
The new mobile exhibition – described inside
and on our website – is one way to raise market
and public awareness about the importance of
clean air and high indoor air quality. We launched
the campaign “at home” in Europe, but the message
is global and relevant to all human beings. Keep in
mind that we breathe around 25,000 litres (6,600
gallons) of air a day and we should be as careful
about our air as our food and drink.
Clean air for life
Several articles in this issue touch upon air pollution
and how it causes harm to humans and impacts the
air we breathe indoors. In the months to come we
will be talking even more about the importance of
clean air, demonstrating how to get it, and explain-
ing the benefits for people, policy-makers and
industry alike. The new mobile exhibition will help us
reach and educate people for this purpose.
Clean air for life starts with good ventilation
and effective and sustainable filtration solutions. It
continues with public awareness of key steps that
can be taken to maintain a healthy indoor environ-
ment and prevent exposure to air pollutants. When
filtration gives us better control over the indoor
environment of our homes, offices, hotels, shop-
ping centres, schools, and other buildings, we are
healthier, feel better and perform more effectively.
Clean air for health, well-being and productivity
– this is our goal.
Pleasant reading!

The dangers of air pollutionThe case for taking stronger measures
to reduce air pollution is becoming
clearer everyday as the media and
the medical community spell out the
dangers of exposure to air pollution.
Pollutants such as airborne particu-
late matter and ground-level ozone
are increasing mortality and hospital
admissions due to respiratory and
cardiovascular disease.
Scientists also say that air pollution triggers
more heart attacks than using cocaine and
poses the same high risk of sparking a heart
attack as alcohol, coffee and physical exer-
tion. Findings also suggest that population-wide
factors like polluted air should be taken more
seriously when looking at heart risks.
Exposure to traffic poses one of the highest
risks since it has the greatest population effect
as more people are exposed to it. Los Angeles
is an example. Here, doctors are studying
asthma and other breathing problems that can
plague American teens living and learning near
the city’s vast network of freeways – problems
that can follow them throughout life and affect
their lung growth.
Even healthy people can develop arrhyth-
mias with acute exposure to air pollution, par-
ticularly fine particulate matter – tiny airborne
grains that can be drawn deeply into the lungs.
Three recent reports
A recent editorial in “The Lancet”, titled “A
breath of fresh air please”, stated that “regu-
latory efforts to curb air pollution on a local,
domestic, and global scale need to be rigor-
ously implemented, enforced, and enhanced.
Governments, as public servants, have the
duty and responsibility to protect the health of
their citizens.” The editorial cites three reports
released earlier this year that underscore “the
importance of having an effective air-pollution
policy for the benefit of health.”
U.S. EPA
The first is the “The Benefits and Costs of the
Clear Air Act from 1990 to 2020”, released
by the US Environmental Protection Authority
(EPA). This report shows that the health ben-
efits greatly exceed the costs of implementing
clean-air protection by quantifying the number
of health-related events preventable as a result
of the Act. The numbers estimated for the year
2020 are dramatic: not only will existing regula-
tions save USD 2 trillion (about EUR 1.4 trillion)
in health costs; it is also estimated that they will
save about 230,000 lives and prevent 200,000
heart attacks, 2.4 million asthma attacks, and
17 million lost working days.
Aphekom
The second report is the three-year Aphekom
research study that was sponsored by the
European Commission and coordinated by the
French Institute of Public Health Surveillance.
In the project, air pollution was surveyed in 25
cities in 12 EU countries, where 39 million peo-
ple live. Curbing air pollution in European cities
could save 19,000 lives per year, add almost
two years to local life expectancy and save EUR
31.5 billion (USD 43.4 billion) in health costs
and work absenteeism, according to the probe.
Particle-value limits are already being
exceeded in various EU member states and
a scheduled revision of present regulations in
2013 is considered a welcome act.
Of all the cities studied, Stockholm was the
only one found to be below the World Health
Organization’s (WHO) recommended level of fine
particulate pollution (10μg/m3).>>>

Hasselt University
The third is an analysis of 36 studies performed
by Hasselt University in Belgium showing that
air pollution is also an important trigger for
heart attacks. On an individual level, the effect
of air pollution is small (5%), but at the popula-
tion level, air pollution is an important factor in
initiating heart attach triggers, such as physical
exertion, alcohol and coffee.
Killing several million
On a global scale, WHO estimates that at least
2 million people suffer premature deaths globally
each year because of the health effects caused
by a lack of clean air. These deaths vary from
region to region. In Asia alone, for example, a
report published last year found that air pollution
in many Asian cities exceeds WHO’s air quality
guidelines and that toxic cocktails of pollutants
cause 530,000 premature deaths a year.
Outdoor becomes indoor
air pollution
Our industrialized world changed a lot of things
for the human population. Increased pollution
was one change that affected our environment.
Today, air pollution is a global problem whose
seriousness varies from place to place. Since
most of its impacts on human health are long-
term, the problem is often overlooked.
This outdoor pollution, which seeps into our
homes and buildings, can easily contribute to
indoor pollution.
Efficient filtration solutions exist to clean air and
protect people but few are aware of the benefits
of clean air for productivity or controlling costs.
Protecting people from the health impact of air
pollution costs money, but it is also a long-term
investment that can reduce the cost of higher
sick leave rates at workplaces and associated
medical expenses, as well as boost workplace
productivity, as documented in studies.
Our right to clean air
At Camfil Farr we believe there is a need to
increase general awareness of air pollution and
to put Indoor Air Quality (IAQ) on the political
agenda. IAQ should be a public health concern.
For example, vulnerable individuals who live
near roads, where air pollution from traffic is a
serious health risk, should fight for their right to
breathe cleaner air. Doctors could be their vocal
allies in this struggle.
We need to pay attention to the importance
of healthy IAQ. Camfil Farr’s vision is clear: clean
air should be considered a human right.
A few years ago, Sleepyhead (Auckland, New
Zealand), a leader in bed manufacturing and bed-
ding technology, installed a large Camfil Farr carbon
filter to remove all traces of the toxic gas toluene
di-isocyanate (TDI) from the company’s brand-new
polyurethane foam production factory.
In 2010, Sleepyhead built a second foam manu-
facturing plant in Melbourne, Australia, and again
turned to Camfil Farr for another carbon filter.
TDI can be hazardous to humans and the wider
environment if it is not handled with care, even in very
small amounts.
To protect process operators, near neighbours
and the external environment, the foam process
is enclosed, extract ventilation is provided and the
exhaust stream is filtered with the Camfil Farr carbon
filter solution to remove all traces of TDI prior to
release to atmosphere.
Protecting production
More TDI-free dreams
Global demand is increasing for smaller, more power-
ful electronics and more advanced displays.
Micronic Mydata, a Swedish high-tech company
engaged in the development, manufacture and mar-
keting of production equipment to the electronics
industry, specializes in pattern generators and sur-
face mount technology.
A recent Micronic Mydata system delivery to a
major customer included Camfil Farr’s Gigapleat to
protect the production process for photomasking
equipment, an integral component in the lithographic
process of semiconductor manufacturing.
Gigapleat is a pleated carbon filter recognized
for its ability to effectively remove harmful gaseous
and airborne molecular contaminants in sensitive
manufacturing environments.
Camfil Farr’s vision is clear: clean air should be considered a human right.

The vehicle for the show is a large trailer truck
that is touring major European cities. During
stops, Camfil Farr air quality experts are track-
ing and comparing live air quality data and
providing information about the harmful effects
of air pollution, which directly affects air quality
indoors, where people spend about 90 percent
of their lives.
The trailer is 13 meters long and has almost
60 square metres of floor area divided into
a mini exhibition, an auditorium for up to 20
people, and four lab stations focusing on IAQ.
A public health concern
Air pollution and poor indoor air quality (IAQ)
become public health concerns and Camfil
Farr wants to inform the general public about
their impact on human health, well-being, per-
formance and productivity. At the same time,
knowledge about the importance of IAQ is
limited. Camfil Farr’s mobile exhibition is mainly
designed to inform politicians, the public and
the media about the importance of breathing
good quality air in the premises where we work
and live.
With test equipment, lab stations and film
presentations, this unique exhibition-on-wheels
clearly shows the type of pollutants contained in
“invisible” ambient air.
Reducing the energy consumption of build-
ing ventilation systems is another purpose of the
mobile exhibition. Electrical power consumed by
air handling units can be significantly decreased
by choosing the right filtration solution. In this
respect, IAQ – as defined by Camfil Farr – also
signifies clean quality air supplied in an energy-
efficient and sustainable way with our filters.
This rolling mobile lab and exhibition provide
a window on Camfil Farr’s world and our goal to
improve air quality, which has a direct effect on
quality of life.
Seeing theory in practice
In the mobile exhibition, visitors learn about IAQ
by watching a movie that explains the basics
about air pollution the sources of air pollution
and its health impacts.
This “theoretical presentation” is turned
practical at four lab stations (see next page),
where visitors learn more about particle quanti-
ties and sizes in outdoor air, how to select the
most energy-efficient filter, the filtration of gases
and the importance of consistent efficiency over
the lifetime of a filter.
Camfil Farr has almost 50 years of experi-
ence in the air filtration market. We have four
R&D centres around the world, dedicated to
learning even more about air quality and its
impacts. We believe that by sharing our know-
ledge, we can help increase well-being and
health at the same time as we help manage
energy consumption and increase productivity.
On the road for cleaner air and better filtration
Camfil Farr is now on a European road show. The objectives are to raise awareness
about the importance of Indoor Air Quality (IAQ), demonstrate the benefits of effec-
tive air filtration and explain how sustainable IAQ and lower energy consumption are
achieved with the right choice of filters.

Mobile lab stations put theory into practice
The four lab stations in the mobile exhibition illustrate some of the basic pillars of Camfil Farr’s clean air concept and air filtration technology.
What do you breathe?
Measuring and defining air quality is difficult
and complex. With the exception of oxygen,
nitrogen and carbon dioxide, the air contains
a number of contaminants that are harmful
to people. These are present in the air we
breathe. This lab station is equipped with highly
advanced measurement equipment to detect
different particle sizes. The smaller the parti-
cles, the easier it is to inhale them. The larger
the particles, the easier they are to capture in
a filter.
The station demonstrates why high-quality
air filters are required for good protection
against traffic pollutants, for example. It also
shows the air quality at the trailer truck’s cur-
rent parked location. The equipment measures
different particle sizes both before (outside)
and after (inside) the filter and then displays the
efficiency of the filter for visitors.
How can you save?
Providing clean air demands energy. But clean
air also saves lives and money. We need air
filters, but we also need to ensure that they are
sustainable and energy-efficient.
At this lab station Camfil Farr demonstrates
the difference that can be made by choosing
the right filter solution. With two identical air-
handling units operating side-by-side, showing
the air flow and energy consumption of two
similar filters, visitors can clearly see how much
energy can be saved.
This is especially important since 70 percent
of the electricity in a building’s energy profile
goes to heating, ventilation and air conditioning
systems.
How can you keep the city out?
Besides particles, gases have a negative impact
on health and productivity. Gases often have a
short-term effect on people, causing respiratory
problems and headaches.
Ozone and nitrogen dioxide are two impor-
tant gases to look at. This lab station shows the
current concentration of these gases (which will
depend heavily on the season) in the air around
the parked exhibition and a molecular filter’s
efficiency at removing these gases.

Environmental Medicine, Department of Public Health Services

What filters do you need?
It is virtually impossible to see all pollutants in
the air. Seeing the exact difference between the
qualities of two air filters is also very difficult.
This lab station uses smoke (an extremely
high concentration of particles) to visualize the
difference between two air filtration systems.
The smoke allows visitors to see the difference
between filtration efficiency and how a low-
quality product performs over time, compared
to a high-quality product.

Welcome!
Busy airports have high pollution levels and airport
officials are eager to prevent harmful gaseous pol-
lutants and odours from entering terminals through
ventilation and air conditioning systems.
CDG in Paris, the second largest airport in
Europe, is building its new S4 terminal to accom-
modate 7.8 million passengers in addition to the 58
million currently served each year.
CDG’s owner, Aéroports de Paris, is committed
to sustainability and reducing energy consumption.
All equipment and material for S4 must there-
fore comply with High Environmental Quality (HEQ)
standards.
Axima, responsible for engineering the climate
systems, has chosen to use only eco-responsible
suppliers. Camfil Farr, recognized for its track record
in sustainable filtration solutions, and for green prod-
ucts with low energy consumption, was first choice
for molecular filtration at S4.
This will be accomplished with several thou-
sand Camcarb Green cylinders to clean more than
700,000 cubic metres of air per hour for a healthier
and safer indoor environment.
Fresh, clean air is guaranteed for actors and audi-
ences at the Copenhagen Opera House/Royal Danish
Theatre, where all ventilation units are equipped with
our low-energy Hi-Flo XLT filters, and at the Vienna
Opera House (Wiener Staatsoper), where Hi-Flo
filters have been installed to ensure high-quality air
through fresh-air ventilation, which is preferred to air
conditioning.
Prima air for prima donnas
HEQ for Paris-CDG
Live measurementsMorning air is different from afternoon air. City
air differs from country air. The mobile exhibition
has three air quality monitoring stations that
continuously report real-time air quality back to
the trailer from different world locations. These
measurement values are compared to local
conditions where the trailer is parked.
In the exhibition, visitors can also watch
a film about IAQ with commentary by Swedish
Professor Magnus Svartengren, a specialist in
occupational and environmental medicine.
“Air pollution is actually a mix of many
different substances. It consists of particles
containing compounds of chemical substances
which vary in size, such as very fine particles
from combustion processes. Pollution can also
consist of a number of gases, of which several
can act as irritants. Then there are chemicals
that can be outgassed from building materi-
als and other sources,” comments Professor
Svartengren in the film.
He continues: “These affect indoor air qual-
ity, which in turn can impact our performance
and health. Poor quality air in classrooms or
conference centres can cause headaches, for
example. Poor IAQ can also have local effects,
such as eye irritation, or affect the airways of
our lungs, aggravating people who have asthma
or causing us to cough. Air pollutants can also
affect lung development in children, or cause
cardiovascular disease in adults. Certain chemi-
cals can also cause lung cancer.”

The air filter market is expanding in Europe. It is
expected to grow even more when all new build-
ings have to meet “zero-energy” requirements
by 2020/21 (2018/2019 for public buildings).
A zero-energy (ZEB) building is a popular
term to describe buildings with zero net energy
consumption and zero carbon emissions annu-
ally. A ZEB is basically a residential or commer-
cial building with greatly reduced energy needs
through efficiency gains.
These “ZEBs” will need effective ventilation
supplying high indoor air quality (IAQ), which
in turn will require the use of high-quality air
filters.
Evolution of filter classes
Over the years, our industry has seen the basic
purpose of air filtration shift. Air filters used
to be selected to protect ventilation equip-
ment – today, their main function is to improve
the indoor climate and protect the health of
people. Today’s polluted air in urban environ-
ments may cause headaches, cardiovascular
and respiratory problems. Clean filtered air, on
the other hand, leads to improved work perform-
ance, reduced absenteeism due to illness and
enhanced well-being.
Over the years, filter classes have also pro-
gressed from low filter levels, such as G4 and
F5, to today’s high filtration classes, F7 and F9,
with F7 being the most common and minimum
class for guaranteeing acceptable IAQ.
Unfortunately, there is a paradoxical rela-
tionship between filter classes and energy sav-
ings because the better the filter, the higher the
energy consumption since a filter’s resistance
to air flow and pressure drop often increase.
Due to their resistance to the air flow, air filters
account for at least 30 percent of a ventilation
system’s energy consumption today.
With energy costs spiralling, the cost of
cleaning, supplying and exhausting air in build-
ings has consequently become a major concern
today and the choice of the right filters can
help. Improving the energy efficiency of HVAC
systems is another way to make buildings
greener and combat climate change. Camfil Farr
is well positioned to help customers reduce their
energy costs because our air filters have the
lowest pressure drop development. Simply put,
less energy is required to “push” air through our
filters, which also provide the added advantage
of maintaining their efficiency longer, compared
to low-cost products with poorly functioning
filter media and/or insufficient filtration area.
In Eurovent’s Product Group 4B “Air Filters”
(PG4B), we have discussed pressure drop
considerably and the energy classification of
filters. The Eurovent Guideline 4/11 – “Energy
efficiency classification of air filters for general
ventilation purposes” – is ready and published
on Eurovent’s website. Starting in January 2012,
Eurovent Certification will certify all fine filters
that will be assigned an energy efficiency class
(A to G) tested according to EN 779:2011. They
will also be classified according to their annual
EN 779:2011 – a step in the right direction

energy consumption, initial efficiency and mini-
mum efficiency (ME).
Let me now comment on EN 779:2011.
A welcomed initiative
The new European standard for air filters
(EN 779:2011) comes into force in autumn
2011. Its purpose is to classify air filters based
on their minimum filtration efficiency (ME) for
0.4 μm particles.
Camfil Farr welcomes the new standard
and considers it a step towards improving IAQ.
The industry has now voted for tougher require-
ments for air filters and the standard will be
published in August this year. National versions
will be available in mid-November, after which
the former standard will no longer apply.
In our view, the new standard will help
eradicate a number of problems related to
filter performance. One of these problems is
associated with electrostatic-charged synthetic
filters. These filters usually demonstrate good
initial filtration efficiency while they keep their
charge, but tend to discharge extremely rapidly,
often after just a few weeks of operation. F7
performance in the lab for an electrostatic-
charged filter can therefore decrease to F5
in real operating conditions, and sometimes
even more. Their cleaning ability deteriorates
considerably as a result. Unfortunately, far
too many European buildings are now using
electrostatically charged F7 filters that have
medium efficiency (ME) values between 5 and
10 percent. As a consequence, as much as 90
to 95 percent of the contaminants in outdoor
air find their way into buildings and pollute the
indoor environment.
By basing classification on an ME of at
least 35 percent for F7, the new EN 779:2011
standard will force these filters out of the
market. At the same time, it will contribute to the
development of synthetic filter materials offering
considerably higher particle separation.
Not all filters are the same – even in
the same class
Regrettably, the price for this will include higher
pressure drops and increased energy consump-
tion.
Camfil Farr has one concern about the new
classification: while the “worst” filters will vanish
from the market, there is a possibility that
“good” filters will be made “worse”. Although
energy savings can be achieved by having the
lowest possible pressure drop, such develop-
ment could be retrograde.
For example, for 0.4μm particles, our
Hi-Flo XLT7 (class F7) filter has an ME value of
56 percent. However, to be classified as an
F7 filter, the standard requires no more than
35 percent for a filter. Camfil Farr’s position on
this is clear: we will not lower the efficiency of
our Hi-Flo filters. Air quality would deteriorate
approximately 40 percent if we did.
However, there is a risk that other manufac-
turers will not think like us. They may see the
standard as an opportunity to reduce pressure
drop and, thereby, energy consumption. This will
unfortunately result in poorer air quality.
At Camfil Farr, we have always put every
effort into improving IAQ. Thus, no one is more
pleased than us that the new EN 779:2011 air
filter standard imposes tougher requirements
even if the requirements are not as tough as we
would have liked and do not meet the quality
standards set for our own air filters.
We welcome further debate and discussion
on this.

Because of this, the test results do not provide a basis for predicting either operational performance or service life. Loss of media charge or shedding of particles or fibres can also adversely affect efficiency.

Camfil Farr’s City-Flo XL has been designed
specifically to deal with growing urban pollution
since it manages both particle and molecular
filtration in a single filter.
City-Flo XL cleans air to remove particles,
odours and gases – including ozone, carbon
dioxide, sulphur dioxide, carbon monoxide and
nitrogen dioxide – as well as volatile organic
compounds (VOCs) and polycyclic aromatic
hydrocarbons (PAHs).
Because City-Flo XL also contains activated
carbon, it removes odours that ordinary filters
miss. City-Flo XL is also extremely effective
against eliminating exhaust fumes.
Along streets and roads with heavy traffic,
City-Flo XL is ideal for use in office complexes,
shopping centres, schools and other public
buildings. The pressure drop across its unique
carbon-filled fibreglass media is very low, saving
energy and money for customers.
Eurovent certified
With City-Flo XL installed in the AHUs of public
and commercial buildings, occupants are guar-
anteed a high level of IAQ as set out in European
Standard EN 13779. The filter is also Eurovent-
certified and P-marked in Sweden. It has a low
initial pressure drop for energy savings, a new
conical bag design and an Ozone 3 rating.
Keep the city out with City-Flo XL
Easy installation
City-Flo XL uses the same single-piece plastic
frame found in many other Camfil Farr filters,
making installation easy if you are already using
our products. When customers have to upgrade
or add to existing filters, there is no need to
replace their old system. With the City-Flo com-
bination filter, they simply change out both the
bag filter and carbon filter.
Poor air is a growing problem in cities. Exhaust fumes, diesel particulates and ozone
generated by increased vehicle traffic contribute to air pollution. Sulphur dioxide, nitro-
gen oxide and other air contaminants are creating serious health problems. At the same
time, European requirements for better indoor air quality are becoming stricter.

Hotel guests are more demanding and discerning
today when they choose hotels. A green environmen-
tal profile is a selling point along with a reputation for
high comfort and cleanliness. Indoor Air Quality (IAQ)
falls in this category.
The five-star Berlin Marriot focuses sharply on
sustainability and Camfil Farr’s low-energy City-Flo XL
solution was chosen as the perfect filter to provide
guests with the best IAQ in accordance with the strict
performance requirements of EN 13779 for ventila-
tion in non-residential buildings.
City-Flo XL effectively removes particles and
odours to upgrade IAQ with the highest possible
energy savings, outperforming all other particulate
and molecular filters on the market.
Best IAQ at the Berlin Marriot
Largest contract to date in India
90,000 Hi-Flo XL filters to save 10 GWh in NorwayGK Konsern AS, the leading indoor climate contractor in Scandinavia, is installing
90,000 Camfil Farr Hi-Flo XL filters in the air handling units (AHUs) of its customers
in Norway to reduce their energy consumption. GK estimates that the filters will save
customers at least 10 GWh of electricity per year.
“10 GWh is actually a conservative estimate of the total projected annual savings when all the filters
are installed,” says Peder Midtstøl, purchasing manager for the GK Konsern AS, which has a share
of 20-30 percent of the professional construction market in Norway. Camfil Farr’s Hi-Flo XL is a new
generation of “green” low-energy filters that cuts the overall operating costs for ventilation systems
and improves indoor air quality (IAQ).
Battling urban pollution
For better IAQ in Norway’s urban areas, GK is also taking the next step in filtration by recommend-
ing customers to install Camfil Farr’s City-Flo XL for particulate and molecular filtration. This filter
is specially designed to battle urban pollution and has a proven broad spectrum capability against
concentrations of most indoor and outdoor pollutants (see separate article).
“As an example, I can mention that we’re now in the process of changing to City-Flo XL at a fire
station in central Bergen,” says Midtstøl. “IAQ has improved considerably since we started replacing
existing filters with City-Flo XL,” he ends.
Due to the phenomenon called temperature inversion, Bergen (photo above) suffers periodic
declines in air quality during cold winter spells and city officials are stepping up efforts to keep risk
groups from being exposed to outdoor air pollution (see AirMail No. 1, 2010). This has also led
to initiatives by facility owners and contractors to improve IAQ, which is directly impacted by air
pollutants entering buildings.
Over the past few years, Camfil Farr Power Systems
(CFPS) has focused on refining its project manage-
ment organization and building up a formidable pool
of international engineering expertise to serve the
global gas turbine business.
These efforts are paying off, as exemplified by a
Siemens order awarded to CFPS India and Germany
for one of the largest natural-gas-based combined
cycle power plants in the Indian private sector.
The plant, located near Rajahmundry and operated
by Konaseema Gas Power Ltd (KGPL), will add an
additional 820 MW of power with two new combined
cycle modules. Camfil Farr India is supplying intake
systems, diffusers, diverters and stack for two
Siemens SGT5-4000F turbines.
In addition to being Camfil Farr India’s largest
single contract to date, the KGPL project represents
a major breakthrough order where both the intake
and exhaust is being supplied for the same turbine
for the first time. CFPS was also a supplier for Phase
1 activities at the plant.

Taking R&D to new heightsIn late 2010, Camfil Farr opened a new
state-of-the-art Technology Center in Trosa,
Sweden. The new centre functions as a
2,500-square-metre innovation hub for prod-
uct and process solutions. It also features
the largest and most advanced laboratory for
Indoor Air Quality (IAQ) research in the air
filtration industry with gas chromatography
and scanning electron microscope.
Other facilities include a high-performance particle
filtration lab and comfort filtration lab with EN 779
(Europe) and ASHRAE (U.S.) testing capabilities; a
Power Systems and Air Pollution Control lab and
a molecular laboratory.
About half of the center’s space is used for Camfil
Farr’s own process development, including machine
construction, concept prototyping and optimization of
industrial processes for filter manufacturing.
The center includes a visitor’s center with full
lecture hall and direct access to all labs.
