Low Energy Air Filters for Indoor Air Quality

The primary purpose of Air Filters in building HVAC systems is to filter and clean air for people to breathe without risk to health.

The secondary purpose of Air Filters in building HVAC systems is to filter air to keep clean and protect the air plant duct system and the internal fabric of the building.

Why we need Air Filters?

The importance of clean air

• 360 000 people in EU die before one’s time because of particle pollutants (Clean Air For Europe)

• Particles from soot are the most dangerous for one’s health (combustion particles)

• Combustion particles are very small <1 µm

• These ultra-small particles causes heart- and vascular disorders

Air Quality problems in the UK

UK Government report indicates PM2.5 pollution is 3X more damaging to public health than passive smoking.

5X more damaging than loss of life due to road accidents

• We spend 80% of our time inside• 50 % of all particles inside come

from outdoor air. 50 % are generated from indoor sources

• The particles penetrate the building through ventilation or leaks.

• Air pollution adversely affects the growth of lung function during the period of rapid lung development that occurs between the ages of 10 and 18. (The New England Journal of Medicine)

The relevant standards for Low Energy Air Filters

The filter test standard that applies to the testing of air filters is EN779:2002

EN13779:2007 advisesF7 as a minimum and

F9 as the advised for required particulate efficiency

Energy consumed by air filters

The cost of ventilation

• The energy requirement for ventilation is expensive.

• Filters account for approx. 30% of the total energy cost of the system. (C.I.B.S.E. data)

• Filters are the most inexpensive part of the system to improve.

• Without Capital Expenditure

Energy Optimisation with Low Energy Air Filters

For example using F7 filter grade as advised by BS:EN13779:2007

Options:

6 pocket 380mm long bag has about 200pa pressure drop initially

12 pocket 635mm long bag has about 85pa pressure drop initially

Over a period of one year allowing for the pressure drop increases as the filters work the estimated save in energy consumption as below.

**Energy £300 the difference in filter price is about £30**

(Ratio 10:1 at 10p per KW/hr.)

21

Energy consumed by Air Filters

Choosing the right bag filter saves Energy

Low Energy Air Filters use an optimised design in order to

minimise energy consumption with Tapered stitch on

pockets.

Poorly manufactured pockets lose performance, use more energy

How we optimise our Low Energy Air Filter selection

A Hi-flo F7 M7 Bag filter with 9.2 M2 of micro-

fibre media has the optimum low pressure

drop and consistent high particulate efficiency

with a longer working life

BS:EN13779:2007 advises F7 minimum efficiency

25

How we optimise our air filter selection

Impact assessment

• 200 Buildings• Serviced by 5 air handing units• Each having 10 standard 2 stage apertures

• Number of 2 Stage apertures • 200 x 5 x 10 = 10,000 apertures

• Will make annual Energy savings (considered on above criteria)

• WILL SAVE ENERGY VALUE OVER 2.3 MILLION POUNDS

• EACH YEAR EVERY YEAR

Life cycle costing & air system factors

Energy is part of the LCC model

The life cycle cost for the filter is the cost of the:

• Filters

• Labour

• Energy consumption

• Cleaning of ventilation system

• Disposal of used filter

= LCC


27

Short Payback time

Air Conditioning Inspection reports can save Energy, Carbon and Money - A typical neglected AHU

• Rare access to poorly maintained AHU’S needing refurbishment.

• Opportunity for solution of Low Energy Air Filters to deliver air of the required Air quality, and using the minimum of energy.

• Short payback time of a few months makes AHU air filter bank refurbishment an attractive option.
