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

Our main goal is to enhance our client’s profitability by im-

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

certification tells you that our products are tested by

independent research laboratory – SP in Sweden and VTT,

Technical Research Centre of Finland – and that the compa-

ny’s published product information must be accurate. All of

our fine filters must meet the requirements of the latest

EN 779 standard.

Trust a certified supplier

Only Eurovent certified supplier’s product information and

markings are monitored independently. Eurovent tests

Halton’s fine filters every year in an independent research fa-

cility and the published information must match the test re-

sults. To ensure quality operations all Eurovent certified sup-

pliers are required to have ISO 9001 or similar quality system.

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

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.

In addition to demanding industrial or research facilities,

HEPA filters can be used when very high efficiency filters

are used for example because of allergies. Together with

a gas filter, EPA, HEPA and ULPA filters can be used

to eliminate odours and smoke for instance in kitchen

environments.

BAG FILTER - M5 glass fibre


C a t a l o g / 1 1 1 2 / E N G


Class M5 filters remove a part of the emissions caused

by traffic and energy production from the air, and also

separate part of cigarette smoke, bacteria, as well as

pollen and spores particles.

Typical applicationsFine filters are designed for purification of intake and

circulation air in air-conditioning systems in facilities such

as offices, public premises and industry. M5 filters are

often used as pre-filters in air handling unit supply side or

as exhaust side filters.

MaterialsThe filtration materials of the fine filters are made of

micro glass fibre. The sturdy and rigid filter media is non-

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 are based

on mechanical deep filtration, thus the material will not

become clogged on the surface, but rather it will fill upevenly. In this way the filter will remain at the specified

performance level through the whole service life.

bacteria.


Panel filters are often also used as a pre-filter in

multistage filtering systems. Panel filters are suitable for

ventilation units, which have limited space for filters.

The filter will remain at the specified performance level,

even in difficult environmental conditions, through the

whole service life.

Materials

Panel filters are manufactured of micro glass/synthetic

fibre having high dust holding capacity and high

resistance to humidity. The filter media is framed by

plastic frame, which makes filters completely incinerable.

Operating range



Final pressure drop recommended



1,0 µm – 77,0 %

2,5 µm – 97,9 %

Structure

Filter media pleats are supported by thin hot-melt glue

traces holding the filter pack firmly in shape. Filter media

designed specifically for applications with small depth

possibility.

Sizes

Halton panel filters are available in standard and

customized sizes. The main frame depths are 48 mm and

96 mm.

RIGID POCKET FILTER - M6-F8, 3 Pocket Model


C a t a l o g / 1 1 1 2 / E N G


The rigid bag filters of this series thanks to their high

filtration surface, low pressure drops, possibility of

complete incineration, compact and robust construction

and growing efficiency during operation can be used as

final filters and for pre-filtration of absolute filters in air

conditioning and ventilation systems.


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

Glass fibre paper. The uniform and close filter pack allows

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.

Operating range

Continuous operating temperature: 70°C

qv=100% relates to the flow rate for the selected filter, see technical

values chart.

In example CLP-RP-P-592-287-290-3-M6-GF-P filter has air amount

2000 m3 /h which corresponds with a pressure drop of 100Pa. If the

desired air amount for a filter is 1800 m3 /h it corresponds with 90% qv

and 80Pa pressure drop.
