The Advantages of Air Filtration

THE ADVANTAGES OF AIR FILTRATION

The air in the Netherlands and Belgium contains high concentrations of incredibly harmful particulate matter. Modern, high-quality air filters create a cleaner indoor climate and consume much less energy. The productivity of employees will increase and your climate control expenses will plummet.

THE IMPORTANCE OF A GOOD AIR FILTER Every company uses a form of climate control. It creates clean air and a pleasant working environment. But climate control consumes a lot of energy. Because of that, producers of air filters invest extensively in energy efficient air filters. Have you been using the same air filter for years? It might be wise to research alternatives. Switching to a more modern, efficient air filter is simple and can save you thousands of euros a year.

Modern air filters filter more harmful particulate matter from the air as well. That is important, because in the Netherlands and Belgium the percentage of particulate matter exceeds the European Regulations. VITO research shows that particulate matter is twelve times more harmful than passive smoking. Polluted air leads to decreased productivity and increased sick leave, and it may even be lethal in the long term. So air pollution is an issue that should be taken seriously.

In this whitepaper we will show you how to save a lot of money and reduce sick leave of your employees by switching to another type of air filter. 3

EXECUTIVE SUMMARY High-quality air filters greatly reduce energy costs Air filters slowly fill up with waste during the day, which causes the resistance to rise and the energy consumption to grow exponentially. In order to keep air filters profitable, you should regularly replace them. New, high-quality air filters have a longer standing time, which considerably reduces installation and material costs. What is even more important is that these new filters have a much lower air resistance during the entire standing time. This greatly reduces the electricity costs – sometimes saving as much as thousands of euros per year.

What can you do now? In order to switch to new, high-quality air filters, the air treatment cabinet does not usually have to be altered. Thanks to the standardised sizes of the EN 15805 norm, you can simply replace the old filters with new, energy-saving filters with a similar or better filter performance.

High-quality air filters reduce sick leave Chapter 2 delves deeper into the serious, negative consequences of air pollution. The percentages of particulate matter in the Dutch and Belgian air are among the highest in Europe. Inhaling polluted air reduces people’s concentration level, increases sick leave and can eventually lead to cardiovascular and lung diseases. Research by the Flemish research institute VITO reveals that particulate matter has a much larger impact on health than passive smoking. Air pollution is a theme that concerns any employer and employee!

What can you do now? By equipping your current air filter system with high-quality air filters, you will also filter extremely small particulate matter from the air. This blows clean air into the workplace and reduces sick leave. • Read more on the harmful consequences of particulate matter in chapter 2. • Contact us for a free particle measurement of your premises.

What is the concrete contribution of high-quality air filters? A modern, high-quality air filter is generally a couple of euros more expensive than a traditional filter. However, these extra costs are nothing compared to the huge net savings resulting from the decreased energy consumption and having to replace the filters less often.

• You save on electricity costs • You save on material costs • You save on installation costs • You reduce sick leave • You increase the productivity of employees • You contribute to corporate social responsibility 4

CHAPTER 1 HIGH-QUALITY FILTERS REALISE A STRONG COST REDUCTION

AAR Source CS TRE I EER PRICE EELOPMET

Why save energy? Our energy needs rise strongly every year. According to data of Statistics Netherlands (CBS), energy consumption between 1950 and 2013 rose by about 4.5 percent every year. If we look at the price development of energy, we can see that the energy price also increases every year. There was not a small drop around 2010, but by now the price level is back to the highest level from 2009.

A large part of the energy costs of companies can be ascribed to climate control. In an average office building the HVAC systems (heating, ventilation, air conditioning) use around 50% of the total energy needs. If these costs are separated further, we can see that around 70% of the HVAC costs consist of energy costs for air filtering. The air filter system is one of the systems that consume the most energy.

Modern filters create a strong energy reduction You can probably see that reducing the energy needs of the air filtration represents a huge saving. And the savings only grow, because energy prices just keep rising.

To understand how you can realise this saving, we first have to explain something about the operation of air filters. To clean the air of a room, a ventilator in an air treatment cabinet (usually installed on the roof of a building or in a technical room) blows in air from outside. Before the air reaches its final destination, it is filtered by one or more air filters and, if required, heated.

The material and the efficiency of a filter determine which gases or particles are stopped. A carbon dioxide filter, for example, is perfect for stopping gases and odours. A HEPA filter, on the other hand, even filters the most minuscule particles from the air, which makes it perfectly suited for clean rooms and hospitals. 5

Saving thousands of euros per month The material and the type of filter are main components in determining the initial air resistance. Simply put, the resistance determines the speed with which the ventilator in the air treatment cabinet should rotate to be able to deliver the right amount of air. Filter pollution has a strong negative effect on the air resistance. The higher the resistance, the harder the ventilator needs to work and the higher the energy consumption – and thus the energy costs. An increased air resistance is an important reason to replace an air filter. Modern efficient filters have a practically constant low air resistance, so energy consumption remains low during the entire life-span. The lower the resistance, the lower the energy costs.

CLIENT CASE New filters save 12,500 euros per year for the residential estate Oosterheem Residential estate Oosterheem has adopted a so-called HD filter, which is a filter with a great storage capacity. The starting resistance of this filter is much lower – and it remains low for the entire standing time. That way, the residential estate was able to reduce energy consumption from 20,000 kWh per month to just 12,000 kWh. Just by replacing the air filters, Oosterheem now saves more than 1,000 euros per month. Michel Bakermans, Management & Innovation employee with Thuisvester says: “We can just see that the new filters save energy.”

CHAPTER 2 AIR POLLUTION REDUCES PRODUCTIVITY AND INCREASES SICK LEAVE Air pollution is everywhere – even inside and at the office. The annoying part is that you cannot see it. However, the effect of air pollution on people’s health is tremendous. It leads to reduced productivity and even a shorter life-span. Annually thousands of people die from the consequences of air pollution, and thousands more fall ill.

Because of that, air pollution is a theme that should be taken seriously. After all, employees spend much of their day in your workplace. By improving the quality of the air there, it is easy to contribute significantly to the wellbeing of your employees.

Particulate matter is twelve times more dangerous than passive smoking Particulate matter is one of the main forms of air pollution. When we talk about particulate matter, we make several distinctions based on size

Gradation of particles

PM10 Particles with an aerodynamic diameter smaller than 10 micrometres. These particles are often described as ‘coarse particles’ and contain dust of roads and industry as well as (0,01mm) particles created by ignition. Depending on their size, coarse particles may get stuck in the windpipe or in the bronchi.

PM2,5 Particles with an aerodynamic diameter smaller than 2.5 micrometres. These particles are described as fine particles and contain secondary aerosols and ignition particles. (0,0025mm) Fine particles may end up in alveoli.

PM0,1 Particles with an aerodynamic diameter smaller than 0.1 micrometre are called ultra- fine particles. Ultra-fine particles are most dangerous because they could end up in a (0,0001mm) person’s bloodstream.

PM is the abbreviation for particulate matter

These epidemiological and toxicological data show that particulate matter, when inhaled, is harmful for a person’s health. This health damage mainly occurs as a result of ultra-fine particulate matter. The particles penetrate the lungs deepest and damage them most severely.

Particulate matter is created by burning fossil fuels and processing substances in industry such as mixed feed, metal and chemical companies. But it may also arise naturally.

Particulate matter is created by

• Traffic emission, such as soot from diesel engines. • Emission from industry. • Emission from residences, such as fireplace, wood stove, barbecue and cigarette smoke. • Natural sources such as sea salt and particles from the ground.

This infographic briefly explains what creates particulate matter, what are the consequences of inhaling it, and how you can protect yourself against it.

The huge consequences of particulate matter Most people breathe polluted air for all of their lives. Many people suffer lung diseases or cardiovascular problems at some point in their lives. Air pollution is part of the reason. Particulate matter enters the lungs when you breathe in, where they can cause harm. It might also cause the blood to become more viscous, raising the chance of heart attacks. In addition, scientists have discovered neurological effects of particulate matter, such as a negative influence on heart muscle functions. 9

Consequences of air pollution: ● Acute complaints like coughing, headaches, eye irritation, concentration problems and shortness of breath. ● Annually 1000 emergency admissions resulting from cardiovascular diseases. ● Annually 1000 emergency admissions resulting from acute airway complaints. ● 3%-5% of the disease burden in the Netherlands comes from chronic exposure to air pollution. ● Annually we lose 135,000 healthy life years due to air pollution.

According to the National Institute for Public Health and the Environment (RIVM), several thousands of people will live several days to several months shorter due to short-term exposure to a high concentration of particulate matter. Even if the concentration is below the European limits, health effects will be visible. 10

Watch this short animated video on what particulate matter is, what causes it and how you can protect yourself from it:

The Netherlands and Belgium do not meet the European guideline The air in the Netherlands and Belgium is among the most polluted in Europe. In many places the measured value of particulate matter is higher than the European norm. In the Netherlands and Belgium the concentration of particulate matter exceeds the limits, especially within 100 metres of busy motorways or within 50 metres of busy city streets. In the biggest municipalities in the Netherlands up to 10% of the population is exposed to an excessive concentration of particulate matter (2004).

HOW IS THE AIR QUALITY AROUND YOU? How is the air quality in your area? The RIVM, the GGD Amsterdam and the DCMR Environmental Services of Rijnmond have developed an app that shows the concentrations of particulate matter, ozone and nitrogen dioxide in around 75 areas in the Netherlands. In addition, the app describes the severity of the air pollution measured. You can also set an alarm value: if this value is exceeded, the app gives a signal. More information on: http://www.luchtkwaliteitmetingen.nl

How do you contribute to the health of your employees? On average an employee spends about 70% to 90% of their time indoors. At home and at work the air quality often leaves much to be desired. If the air outside is polluted, the air inside usually is, too. This can lead to the sick building syndrome (SBS). Almost three quarters of SBS cases can be ascribed to the ultra-fine particles in the air. Well-known symptoms are lethargy, concentration and airway issues, headaches, drowsiness, irritation of the skin or eyes, and exhaustion.

Employees spend much of their week in the workplace. Because of that, it is important to protect them from the consequences of air pollution. Proper air filtration is a simple way of protecting employees. Just replacing the current air filters with high-quality filters makes a significant difference. It reduces sick leave among employees and – as we have seen in the previous chapter – the energy costs when using high-quality filters are considerably lower.

Win-win situation: cleaner air, high savings Modern, high-quality air filters filter particulate matter from the air and create a healthy working environment. In most cases the current air treatment system does not have to be adjusted. Just replacing the filters is enough.

By making the right choice, you not only choose for a better air quality, but also for a great cost reduction, as described in the first chapter. When determining the right filter, there are a couple of features to take into account:

• level of filtering • energy consumption • particle storage capacity

The table below details these aspects per filter type.

Filtertype Level of filtering Energy consumption Particle storage capacity

HPQ compact filter with high protection from +++ +++ extra filter surface particulate matter
