Filtering Fine Dust from the Air with Fine Dust Filters
Fine dust filters, also known as air filters, play an important role in removing fine dust from the air. Here are some reasons why using filters is important for filtering fine dust:
Health Protection
Fine dust filters help remove fine dust particles from the air that would otherwise be inhaled. By purifying the air of these particles, fine dust filters reduce the risk of respiratory problems, allergies, and other health issues caused by exposure to fine dust.
Improving Air Quality
Using fine dust filters contributes to maintaining or improving the overall air quality in indoor spaces. This is especially important in urban areas or areas with heavy traffic and industrial activity, where fine dust concentration is often higher.
Extending the Lifespan of the Ventilation System
Fine dust particles in the air can be harmful not only to health but also to the mechanical ventilation system. Fine dust filters prevent dust particles from accumulating in the air ducts and air treatment equipment, which extends the system's lifespan and reduces maintenance needs. It also prevents the growth of bacteria and mold.
Fine dust filters help create healthier, cleaner, and safer indoor air, while simultaneously reducing the impact of fine dust on health and the environment.
What is Fine Dust Exactly?
Fine dust, also known as Particulate Matter (PM), is a form of air pollution. Fine dust consists of particles suspended in the air with an aerodynamic diameter of 10 microns or smaller (PM10). These particles come from various sources and have different chemical compositions. The composition of fine dust is influenced by the environment and weather conditions.
Health Risks of Fine Dust
Epidemiological and toxicological studies show that (especially long-term) inhalation of fine dust is very harmful to health. A recent report from the European Environment Agency (EEA) shows that in Europe, 350,000 people die prematurely every year due to inhalation of fine dust. Vulnerable groups such as the elderly and people with heart, vascular, or lung diseases are at high health risk with chronic exposure to fine dust. The research also shows hindrance during the development of the lungs in children.
Fine dust can harm health in various ways, depending on the size of the particles and how deeply they penetrate the human body. The smaller the particle, the deeper it can reach within the body.
The main particle sizes that can be harmful to health are:
- PM10 (Particulate Matter 10 micrometers): Particles up to 10 micrometers can reach the upper airways, such as the nose and throat. They can cause irritation of the airways and lead to symptoms like coughing and a sore throat.
- PM2.5 (Particulate Matter 2.5 micrometers): These smaller particles can penetrate deeper into the airways and even reach the lungs. They can cause severe health problems, including exacerbation of respiratory conditions such as asthma and bronchitis, increased risk of respiratory infections, and cardiovascular diseases.
PM1 Fine Dust is the Most Harmful
It is well known that the greatest health damage occurs particularly when inhaling smaller particles, particles smaller than 2.5 microns: PM2.5 and smaller. While particles larger than 10 microns are blocked by nasal hairs and mucous membranes, particles of 2.5 microns and smaller can penetrate into the alveoli. In the lungs, damage occurs that makes it more difficult to absorb oxygen. This can result in shortness of breath and a feeling of suffocation. Ultrafine dust, particles with an aerodynamic diameter smaller than 0.1 microns, can penetrate into the bloodstream through the alveoli. This negatively affects the composition of the blood and can lead to infarctions.
How Do We Select the Right Fine Dust Filter?
Measuring = knowing. Therefore, before giving filter advice, we measure several factors. To provide the right advice, we use the Eurovent 4/23 guideline. This guideline determines the minimum recommended ISO16890 filter efficiency based on ODA (Outdoor Air) and SUP (Supply Air).
To determine the correct ODA category, we need to understand the outdoor air quality and how much fine dust is present in the outdoor air. ODA 1 represents the least fine dust pollution in the air, up to ODA with the highest fine dust concentrations. Then, we determine the SUP category of the specific location, ranging from SUP 1 (spaces with high hygiene requirements and high occupancy) to SUP 5 (spaces with minimal human traffic). After determining the ODA and SUP categories, we can establish the minimum recommended filter efficiency required to achieve clean and healthy indoor air quality.
Selecting Fine Dust Filters Based on Air Quality Measurement
Based on our fine dust measurements, we first map the ambient air quality. Here, we measure the fine dust level in your environment. This is the air that will enter the building through the ventilation intake. Then, we measure the concentration of fine dust behind the filter currently used in the air handling unit. From this point, we can determine whether the fine dust filter meets current guidelines and standards, which we strictly follow. In other words, does this filter effectively block fine dust? We will measure in multiple locations within the building to assess the overall indoor air quality, particularly where the most staff are present. The results of the aforementioned measurements help us determine if the indoor air quality on-site meets the standards. If not, we will advise and assist you during the subsequent optimization process.
Comparing Fine Dust Filters Using Our Tool
Once the minimum recommended filter efficiency is determined, we look at the type of fine dust filter (e.g., panel, compact, or bag filters). There are different types of each filter, such as different media. We offer our customers the opportunity to select the fine dust filter that best meets their needs and requirements. We offer various types that can be compared using our self-developed tool based on filter class, lifespan, energy consumption (and costs), CO2 emissions, and purchase costs. We also provide advice or present the various options with pros and cons, allowing the customer to select the desired fine dust filter.
Knowledge Sessions on Fine Dust Filters: The (Inter)filter College
To best protect ourselves against the dangers of fine dust, it is essential to apply the right fine dust filters. We realize that due to constant changes and new developments, one may not know which filter type performs best in each situation. Don't worry! With our years of expertise, we can guide you through any situation to achieve the desired result: clean and healthy indoor air. Our goal is to share our knowledge with our partners. Therefore, we hold weekly knowledge sessions where we share our expertise with our clients. This way, they can use this knowledge to apply the right fine dust filters everywhere. You can attend these knowledge sessions at our location, or we are happy to come to your location. Interested in our (Inter)filter College? Contact me.
