Halton - Enabling wellbeing
Filter material is available
in glass fibre and synthetic
materials. Coarse glass fibre
mat is used for separation
of particles e.g. in paint-
booth systems or carpenter´s
workshops and metal industry.
Coarse bag filter is the
solution for removing the
largest particles, such as sand
and pollen, from the air.
A fine filter manufactured
from glass fibre removes
efficiently bacteria and
particles, as well as a
large part of the emissions
caused by traffic and energy
production.
HEPA-filter removes almost
100 % of the impurities in the
air. These types of filters are
used in hospitals and industry.
Carbon filters are used for
removing gaseous compounds
and odours from the air.
Filter housing is used for
assembly of filters if the
filter needs to be located in
the duct system. Housing
is manufactured for pocket-,
panel-, HEPA- and cylindrical
carbon filters.

Defining customer requirements
Appropriate filtration solution saves energy
Our experts examine the ventilation system of your
building during the building assessment, and design
optimal filters for each location. This is how we can be
sure the filtration meets the requirements and functions
energy efficiently without unnecessarily broken filters.
Things to consider when choosing a solution include the
environment, equipment and intended use of the facility.
Equipment specific assessment
Assessment of filtration system is always equipment
specific. It includes among other things information on the
facility, number of the air handling unit, range of operation
and location as well as measurements for the filters fitted
in the machine. Once the precise location of the equipmentis known, the right filter will definitely end up in the right
place. A sign on the air handling unit filter section usually
has the following information: machine number, air flow
rate and filter class. Sometimes also the type of filters and/
or surface area required of the filter.
Replacement interval of filters
Appropriately measured filtration solution is designed
according to the air handling unit’s dimension,
airflow rate, and indoor air quality targets. Air
filter’s replacement interval depends on the
specific equipment’s inner/outer conditions, the
desired filtration results, filter material, and energy
consumption estimate.
If the only used indicator for replacement is pressure
drop, it won’t tell reliably when the filter needs to be
replaced or the filters hygienic status – it will only
tell the very last moment to change to a new filter.
Once the filter is clogged, the airflow passing through
it decreases significantly and increases the energy
consumption. Depending on the amount of use, the
recommended replacement interval is approximately 6
months. In two stage filtering the coarse filter should
be replaced every 3-6 months and the fine filters
every 6-12 months. More information regarding the
replacement can be found in this publications part;
Installation/replacing bag filters.
The replacement interval for HEPA filters is usually a
fixed time, for example 12 or 24 months, and it is based
on maintaining the cleanliness of the space and the
maintenance routines of the facility. It is also assumed
that there is a multistage filtering solution before theHEPA filter. Such a solut ion prevents HEPA filter from
clogging with large particles. If there is no multistage
filtering, the HEPA filter needs to be replaced at least
every 12 months or according to differential-pressure
measurements.
In case of gas filtration life cycle, see Gas filtration
assessment, design and delivery.

Dimensioning a right solution
Filter choice impacts on product lifetime and facility´s
energy costs
It is relevant to the ventilation systems functionality that
the filters are dimensioned properly. Air handling unit’s
technical properties, such as the air flow rate and physical
measurements define what kind of filters should be used.
Effects of the filter´s filtering surface area
In terms of filter functionality it is relevant that the airflow
velocity (m/s); air pushed through the filtering material is
appropriate. The airflow velocity is controlled with filter’s
surface area: the more effective the air handling unit is,
the more surface area is needed. The amount of surface
area also depends on the level of filtering: the higher the
level of filtering, the greater is the pressure drop over the
filtering media.
Appropriate amount of surface area impacts:
• Filter’s expected lifetime
• Filter efciency
• Energy consumption of the ventilation equipment
Calculating the correct surface area
Calculations for filter’s filtering media’s surface area
are based on ventilation equipment’s air flow rate and
selected filtering class. The formula for calculating the
surface area is:
Airflow (m³/s) ________________________ = needed surface area (m²)
Air material speed (m/s)

A case study 2: Calculation of air velocity and
review of pressure drop
You want to find out if the chosen filter is right for your
air handling unit. The airflow rate passing through the
filter is 0.900 m3/ s and the chosen filter class is glass
fibre F7 filter. Its size is 592x592 mm and the length of
the pocket 635 mm and it has 10 pockets. Additionally
you want to know this filter’s pressure drop.
1) Calculate the filter’s surface area
597 mm * 635 mm x 10 x 2 = 7.58 m2
(Mean height of the filter pocket x Pocket length x
Pocket amount x 2)
Desired airflow rate is 0.900 m3 / s and it is inspected
for airflow rate/surface area
0.9 m3 /s / 7.58 m2 = 0.119 m/s.
This airflow velocity is within the range of acceptable
values for the given filter class, under 0.15 m/s.
2) The choice of filter is done and we can go on to
inspect the products’ pressure drop.
Halton’s LCC software calculates the pressure drop as
86 Pa.
NOTE! It is not usually possible to find out the
product’s pressure drop from a product chart, but the
Halton LCC software calculates mathematical pressure
drop by using several parameters. The sales personnel
at Halton can tell you all about your product’s suitability.
Typical problems
If the surface area is too small in relation to the airflow,in the worst case scenario, the filter can be torn due to
added stress from the pressure. It is also possible that
force of the pressure on too small surface area loosens
the dust particles and they flow in to the duct and into
the indoor air. The filter’s surface area is proportional
to its lifetime expectation and its operational
effectiveness.
It is also possible that the location of the equipment
in relation to the duct has been designed or built
improperly, so that the air flow to the filter section is
very turbulent and it is directed on only one filter or
filter pocket surface and thus causes a broken filter
even though mathematically the filter is within the
accepted limits. In this situation, often there is not
much else to be done except to make changes to the
air handling unit and/or the ductwork.
A case study 1: Calculation of filtration area
Filter class for an office space is F7, the ventilation
equipment’s airflow is 5,4 m3 /s and there’s space for
six standard sized filters in the air handling unit. In the
selected class the desirable airflow velocity through the
filtering fabric is 0,10 m/s. In order to have the right air
flow speed through the material, the filtering surface area
must be large enough.
1) Necessary surface area:
5,4 m³/s __________ = 54 (m²)
0,10 m/s
Because there is space for 6 filters, in each filters there
must be a surface area of 9 m² (54 m² / 6).
2) Choose an appropriate standard sized filter with a
surface area at least 9 m².

Gas filtration assets, measurement and
delivery
Right product for right location
Halton offers a broad range of gas filtration products from
light smell control to heavy-duty industrial solutions. Our
local sales people and experts will help to assess the
conditions in the facility and find the right solution.
Replaceable filters
Halton provides a wide variety of different gas filtration
products. Once there is enough information of the
conditions in the facility, a filter with the right filtering
capacity and connection type can be chosen. Some of the
gas filtration products demand their own individual frames,
some fit directly into bag filter rails (25 mm rail) and some
can be fitted into regular rails with an additional fitting
accessory. In heavy-duty gas filtration units particles and
gases can be filtrated with separate products, in lighter
solutions the same filter can have both gas filtration and
classified particle filtration.
For more information on replaceable filter options, see
chapter Gas fltration assets.
Defining life expectancy
Considering the complete process cuts costs
Deciding when it’s time to replace a chemical filter
happens a bit differently than with mechanical filtration.
For instance, with chemical filters the pressure drop
doesn’t really increase with age, so the replacement
interval can’t be based on that. Information on when it’s
time to change a new filter can and should be gathered
with different methods. One way to get information on
the condition of the filtration media is a material analysis
performed in a laboratory. Other ways include corrosionplates, estimating filter performance based on smell
and different electro-chemical indicators. Knowing the
processes and performance environment in the facility as
well as recording and analyzing past results are keys to
finding well-timed replacement interval.
When ways of defining the life expectancy of gas filtration
are planned in accordance with the conditions in the
individual facility, it is usually possible to reduce the
amount of testing and attached costs.

Environment and disposal
disposal by burning or gathering at dumping area can be
justified in some cases. Considering the environment avai-
lable alternatives of disposal, the sort of waste, the way
of collecting waste, distance of transport and the way of
transport are the factors which will affect the most useful
alternative of disposal. For that reason Halton has many
different frame and filtering material options in the pro-
duct range. Different material options are complementary
to each other and make possible to find the best solution
for the customer´s needs in different facilities.
The most common ways of disposalAll Halton filters can usually be recycled and utilized as
energy waste through industrial processes. This is an ef-
ficient way to reduce the amount of trash gathered at
dumpsites and to follow the obligation to reuse waste
mandated by waste laws. Used filters can easily be de-
molished as unsorted waste as well. Before demolition it
must be made sure that the levels of impurities filtered by
the product do not exceed the officially stated levels.
Environmental impact
The environmental impact of the filter includes its´ who-
le service life starting from raw material processing, ma-
nufacturing of the filter itself, energy consumption during
the use, transportation and finally to the disposal. Halton´s
aim is to work comprehensively towards environmental-
ly friendly solutions without making any compromises in
filtration efficiency. This is done by investing in continuous
product development, increasing the efficiency of its´ own
business and knowing customer´s operating environment.
In a key position is the continuous co-operation with the
best partners in the business.
Disposal is a local thing
The filter is composed of the frame and the filter material.
In addition the filter will collect impurities from the air du-
ring the use. The used filter can be disposed in many dif-
ferent ways. The way of disposal which will be environ-
mentally friendliest, depends on local circumstances. The
recycling of the material is the best alternative, but the

proving indoor air quality with new energy and environment
saving indoor air solutions. We operate responsibly and hon-
estly. Our quality is built on among other things following in-gredients.
Halton´s fine filters are Eurovent certified. That means that
our filters are tested in an independent laboratory. This way
the quality of our products and the accuracy of our market-
ing material are ensured. Halton is one of the few European
manufacturers, to whom this certificate has been rewarded.
In addition to Eurovent certified tests we test new material
shipments regularly at VTT, Technical Research Center of Fin-
land. Therefore our clients can be assured of the quality of
the Halton products. If necessary, the test reports are availa-
ble through our Regional Sales Managers.
Quality and environmental aspects guide our operations.
Halton has been rewarded the ISO 9001 quality certificate
and ISO 14001 environmental certificate. As an environmen-
tally responsible player we have also begun preparations for
calculating our carbon footprint. Our aim is to reduce green-
house gas emissions while achieving cost reductions by en-
hancing our operations.
Eurovent - Know what you are buying
When our clients buy Halton fine filters they can be assured
they will receive high quality filters. Europe’s air conditioning
and cooling industry’s manufacturers’ association, Eurovent’s

Life cycle calculation(LCC)
About 70-80 % of the air filtration costs come from
energy consumption. The principle is that the filter
should filter air pollutants as effectively as possible while
causing as little resistance to the air flow, i.e. pressuredrop, as possible. The less there is pressure drop, the
less energy is spent, and the more money is saved. It is
worth remembering that usually a smaller pressure drop
also means lower efficiency. Energy consumption should
not be the main driver in choosing air filters. The filter
efficiency should always come first.
Halton’s filters are manufactured with a method that
guarantees their optimal functionality as well as small
pressure drop. Energy efficiency is ensured with Halton’s
LCC software, with which comparative results can be
calculated for different filter classes and surface areas
in the client’s environment. Life cycle calculation looks
into ventilation’s capital costs, energy costs, cost of
maintenance and cost of disposal. Halton’s LCC software
has been developed together with VTT, Technical Research
Centre of Finland, and it presents the energy saving
potential of each facility in clear pictures and graphics.

Instructions on how to choose a filter
These days building maintenance is more technical than
ever and it requires reliable and competent partners.
Halton’s task is to work comprehensively towards cleaner
indoor air thus providing added value to our clients. We
design, assess and maintain our client’s filter systems. As
a big supplier we are able to guarantee on-time deliveries
and installations.
Below is a list of things to consider, when choosing filters
and filter suppliers. Choosing the correct filter is one of
the most important factors in the economic maintenance
of quality ventilation system, so it’s worth putting thought
into it.
Assessing the need for filtration
In order to have the best possible filtration results, invest
time on selecting the right filter with the help of an
expert. Find answers to at least the following important
questions:
• What kind of space/spaces the air ltration serves?
• What is the required lter class of the facility?
• What kinds of impurities are there in the surrounding
air?
• What are the technical demands of the site, in other
words the technical attributes of the ventilation equip-
ment as well as the type and size of the lters?
When you are asking for an offer
Make sure you operate with a reliable partner, who knows
the industry. Filter supplier should be required among
other things to have:
• Third party certicate (e.g. Eurovent)
• ISO 9001 quality certicate
• ISO 14001 environment certicate
• Expertice to do professional site surveys
• Broad range of products and high performance capability
• Readiness to offer LCC-calculations
• Possibility to offer regular training and guiding to clients

Test and standards for HVAC filters
EN 779:2012
EN 779 standards defines the test methods and filtrati-on classifications for coarse (G1-G4), medium (M5-M6)
and fine (F7-F9) filters. EN 779 standard includes three
different test methods depending on what filter class
will be examined.
Coarse filters (G1-G4) are tested according to the gravi-
metric method (arrestance, dust holding capacity). The
removal of dust is measured by loading the filter step
by step with ASHRAE-dust, in constant air flow until
their final pressure reaches 250 Pa. Filters are classified
according to the average arrestance of these individual
arrestance measurements.
Medium filters (M5-M6) are tested for their ability to
remove (DEHS) particles. The fractional efficiency is
measured by particle size between 0,2 µm and 3 µm.
The fractional efficiency is measured as new and then
after several loading phases with the ASHRAE-dust.
DEHS aerosol is used for measurement between each
loading phase and after the last loading until their final
pressure reaches 450 Pa. It is then possible to calcula-
te for each different particle size the average efficien-
cy of an individual measurement. Filters are only clas-
sified according to their average efficiency of 0,4 µm
particles.
Notice! It should be remarked
that the average efficiency (classi-
fication) can be a completely mis-
leading value. Filters with high
initial efficiency, can after dischar-
ge drop significantly in operating
conditions.

Fine filters (F7-F9) are tested otherwise in the same
way as medium filters, but additionally a discharge testwith isopropanol is performed.
In all methods the dust holding capacity is measured
until the final test pressure drop is reached.
The filters are supposed to be tested without extra mo-
difications or any pre-treatment or preparation.
The EN 779:2012 report includes initial test results
(when filter is new), curves indicating pressure drop,
particle efficiency (0,4 µm) and arrestance for synthetic
dust as a function of the mass of dust fed.
The average efficiency and arrestance at different final
pressure drops are also to be reported. The efficiency
of initial untreated material, together with the efficien-
cy for discharged material, must also be reported in the
test summary, but does not effect the filter´s classifica-
tion.

EN 13779 Indoor air classification and requirements
EN 13779 defines the indoor air quality (IDA) in occupied
zones in 4 categories. There are no default values for
these categories (it is outside the scope of the standard).
However local or national regulations may define CO2
levels, airflow rates or concentration levels of specific
pollutants.
For hygienic reasons outdoor air should be filtered in two
stages (at least for IDA1 and IDA2) and with minimum
F7 filter quality. Minimum M5 quality should be used for
exhaust air.
Gas filters are recommended in areas of category ODA3
and it can also be a good solution in category ODA2 in
case of gaseous pollutant outdoor.
Gas filters should generally be combined with filters F8 or
F9. It is important to protect the filters from getting wet
and to achieve that, then the relative humidity should be
less than 80 %.
Filter replacement
• The lters in the rst ltration stage should be replaced
after 2000 hours of operation or maximum one year.
• The lters in the second ltration stage, as well as l-
ters in exhaust or recycled air systems, should be rep-
laced after 4000 hours of operation or maximum of two
years.
• For hygienic reasons, the lters should be replaced af-
ter the main pollen and spore season in the autumn. If
requirements are stringent, the filters can also be chan-
ged in the spring after the mechanical heating system
during the winter has been switched off.
EN 1886 Filter bypass
Filter casing/frame and filter’s connecting surface must be
as tight as possible to avoid filter bypass. Acceptable filter
bypass in a ventilation system and the measurement con-
ditions have been stated in standard EN 1886. The values
for the highest accepted filter bypass amounts given by
the standard are presented in table below.

EN 1822: EPA, HEPA and ULPA filters
EPA (Efficiency Particulate Air filters), HEPA (High
Efficiency Particulate Air filters) and ULPA (Ultra Low
Penetration Air filters) filters are tested and classified
in Europe according to the EN 1822:2009 standard.
The class and grouping are based on filter’s average
efficiency/penetration. In a test consistent with the
standard airflow is pushed through the filter at its nominal
air flow. Dust with average particle size best suited to
pass through the filter material (MPPS, Most Penetrating
Particle Size) is fed into the airflow and the amount of
particles is measured both before and after the filter.
The filter is assigned both a local efficiency/penetration
value, in which the surface of the filter is scanned to find
possible local bypasses as well as an overall efficiency/
penetration value, in which the average of the whole filter
Standards and classification of HEPA-filtration
is considered. The filter class is assigned according to the
test results. Filter classes H13-U17 are given a special
test certificate, which clarifies the distinctive test results
of the filter.
EN 14644: Using HEPA filters in cleanroom applications
HEPA filters are used to ensure the air purity in
various demanding facilities. For example, in hospitals,
medical research, nuclear technology, war technology,
microelectronics, food industry and space technology.
Classification of cleanrooms and other controlled
environments according to the amount airborne particles
is defined in standard EN ISO 14644. Airborne particulate
cleanliness is marked with an ISO classification number.

In addition to cleanliness classification, the EN ISO 14644
standard deals with cleanroom design, building, testing,
use and monitoring. Besides monitoring the quality of the
filter having control of these other factors is extremely
important in order to achieve the particle levels set for
the cleanroom. Proper pressurization, sealing of the
structures and ventilation, movement and clothing of the
personnel, cleaning methods of the spaces and control
of the equipment used in them have an important role in
controlling the particle amounts of the cleanroom.

BAG FILTER - F9 Glass fibre
General characteristicsClass F9 fine filters remove a notable part of the emissions
caused by traffic and energy production, and also separatevery efficiently e.g. cigarette smoke, bacteria, as well as
particles causing dirt collection. The glass fibre filter classF9 filter can be considered as the most efficient bag fine
filter on the market and surely meets the standard for highperformance for the very demanding customer.
Typical applicationsFine filters are designed for purification of intake and
circulation air in air-conditioning systems installed infacilities such as offices, public premises and industry. A
class F9 filter should preferably be used with a pre-filter toensure a long service life.
MaterialsThe filtration materials of the fine filters are made of
micro glass fibre. The sturdy and rigid filter media isnon-flammable. Thanks to the strong structure of the
material, the filters are easier to handle and keep their
shape better. Bag filters made of micro glass fibre arebased on mechanical deep filtration, thus the material
will not become clogged on the surface, but rather itwill fill up evenly. In this way the filter will remain at the
specified performance level, even in difficult environmentalconditions, through the whole service life.
Operating rangeMax. operating temperature: 93°CRelative humidity: Max. 100%
Pressure drop recommended
for filter replacement: 450 PaInitial efficiency: 0,4 µm – 84,0 %
1,0 µm – 99,7 %
2,5 µm – 100 %StructureThe inner and outer frames of the filters are madeof galvanized steel or incinerable plastic. To ensure
tightness, the filter pockets are glued to the outer frame.Correct opening of the filter pockets is ensured by using
distance holders sewn into the fabric; reliable and correctfunctionality as well as high dust holding capacity is thus
ensured. The sewing seams are sealed with hot melt glue.

and growing efficiency during operation can be used as
final filters and for pre-filtration of absolute filters in air
conditioning and ventilation systems.
Typical applications
Rigid pocket filters with mini-pleated extended filtering
surface, are used for fine dust filtration in public premises
and industrial air conditioning systems. The main
advantages of such construction are a low pressure loss
and a long life time. With a flange of 25 mm filters may
be installed into standard mounting frames.
Advantages
• Strong plastic frame and rigid construction
• Ease of maintenance• Long service life
• Filters are completely incinerable
• Low pressure drop
Media

the various panels of the filters and elevated crossing
surface to hold fine dusts.
Sealant
A polyurethane resin guarantees the seal between the
filter pack and frame.
Frame
Robust structure in pressed extruded polystyrene,
containing the filtration packs laid out in a multi V shape,
also known as rigid bag filters. The light and compact
construction gives the filter a superior mechanical
resistance compared with traditional bag filters.
