How do energy-efficient filters contribute to CO₂ reduction?

Energy-efficient filters reduce the energy consumption of your air handling system, directly lowering your building's CO₂ emissions. In addition, the filters require less frequent replacement, resulting in: Fewer service visits and transport movements Reduced production of new filters (saving raw materials) Less waste and waste processing Together, these benefits provide significant additional CO₂ savings on top of the energy savings achieved by the ventilation system itself.

Save up to 68% Energy with Nanowave and Coarsewave Air Filters

22-08-2024 | Air Filtration

Are you responsible for a building or industrial installation? Then you know how significantly HVAC systems impact your energy consumption. On average, one-third of a building's total energy use comes from air handling. With energy-efficient Nanowave and Coarsewave pocket filters, you can quickly reduce these costs without major investments or technical modifications.
These filters offer lower pressure drop, reduced energy consumption and a longer service life. As a result, you save not only on electricity but also on maintenance and filter replacement costs. In this article, we explain how savings of up to 68.9% are achieved and how a Total Life Cycle Cost (TLCC) calculation can provide insight into your potential cost savings.

How energy-efficient filters reduce energy consumption

Air filters create pressure drop within HVAC systems. The higher the resistance, the harder the fans have to work, resulting in higher energy consumption. Nanowave and Coarsewave filters feature a low initial pressure drop, allowing your system to operate more efficiently without compromising indoor air quality. In short:

Optimal airflow is maintained

Fans consume less energy

Filter efficiency remains stable

Nanowave fine particle filter for optimal indoor air quality

The Nanowave is an ePM1 fine particulate air filter. It captures ultrafine particles, allergens, bacteria and viruses while maintaining low airflow resistance. It is ideal for offices, healthcare facilities and educational buildings. With a service life of up to 3 years, it reduces replacement costs by 2–3 times. In many cases, the filter pays for itself within its first life cycle.

Coarsewave coarse particle filter for maximum energy savings

The Coarsewave is an ePM10 / ISO Coarse pocket filter designed to capture coarse particles such as dust, dirt, sand and pollen. It is ideal for industrial facilities, warehouses, dusty environments and multi-stage filtration systems.

Total Life Cycle Cost: understand your total savings

Thanks to the long service life of Nanowave and Coarsewave filters, the initial investment is recovered through lower energy consumption, fewer filter replacements and reduced maintenance costs. Using the Total Life Cycle Cost (TLCC) method, we calculate all costs throughout the filter's lifetime, providing a realistic overview of your potential savings rather than focusing solely on the purchase price.

How does the TLCC calculation work?

1. We use official monitoring data, including government air quality stations, to determine local particle concentrations and pollution levels.

2. We analyse the airflow through your air handling unit (AHU) to determine the amount of particulate matter the filter must capture.

3. Based on the filter class, we calculate the percentage of particles captured and the amount of dust the filter can hold before pressure drop increases.

4. We calculate how the filter's pressure drop develops throughout its service life and how this affects fan energy consumption.

5. We combine energy costs, replacement intervals, maintenance and waste disposal costs into one comprehensive calculation to determine your total cost savings.

Frequently Asked Questions About Energy-Efficient Filters

Your fan uses less energy while maintaining the same air quality. This helps you achieve long-term savings on energy costs.

Nanowave (ePM1) captures ultrafine particles and microorganisms, while Coarsewave (ePM10) filters coarse dust particles and pollen. They are often combined in multi-stage filtration systems.

It depends on air quality, airflow volume, and operating hours. Energy-efficient filters maintain their performance for longer thanks to their lower pressure drop.

The TLCC (Total Life Cycle Cost) shows the true cost of filters, including purchase, energy consumption, and replacements. By using air pollution data, the airflow rate of your air handling unit (AHU), and filter efficiency, we can predict how pressure drop and energy consumption develop throughout the filter's service life. This gives you a clear picture of the actual savings—not just the purchase price.

Yes. Our Total Life Cycle Check provides a customised calculation for your project or facility, showing exactly how much you can save on energy and maintenance compared to standard filters.

Yes. You can request a Total Life Cycle Check via our online form. We will contact you to prepare a personalised calculation of your potential cost savings.

After submitting the form, our specialists will contact you to analyse your site or project. This includes evaluating the airflow rate of your air handling unit and the specific characteristics of your building or installation. Our calculations use air pollution and particulate matter data collected by the Dutch government through multiple monitoring stations (Atlas Leefomgeving). By combining the number of particles passing through your AHU with the Dust Holding Capacity (filter efficiency) of the selected filter, we can determine:

How quickly the filter pressure drop increases throughout its service life
The impact on energy consumption in kWh
The resulting energy savings, maintenance savings, and total life cycle costs

Following the analysis, you will receive a personalised overview of the potential savings and total life cycle costs of your filters. This allows you to clearly understand the impact a Nanowave or Coarsewave filter can have on your building or project.

Yes. In fact, combining Nanowave (ePM1 fine particle filter) with Coarsewave (ePM10 coarse particle filter) in a multi-stage filtration system is highly recommended. This ensures effective removal of both coarse and fine airborne contaminants.

Specifications

Nanowave filters have an average service life of up to 3 years, while Coarsewave filters can last up to 35 months. The exact replacement interval depends on local air quality, airflow volume, and the filtration system.

The more polluted the air, the faster filters become loaded and the quicker pressure drop increases. Dusty or heavily polluted environments may shorten filter life, while cleaner environments allow maximum service life.

The difference lies in the filter classification rather than the filter itself. Since 2018, the former European EN 779 classifications (such as F7, M5, and M6) have been replaced by the ISO 16890 standard, which provides a much clearer indication of the particle sizes actually captured.

ePM1: Ultrafine particles (<1 μm) = F9 / F8 / F7
ePM2,5: Fine particles (up to 2.5 μm) = F8 / F7
ePM10: Coarser particles (up to 10 μm) = M6 / M5
ISO Coarse: Coarse dust, sand, dirt, pollen = G3 / G4

By monitoring the filter's pressure drop. Once it exceeds the recommended maximum, the filter is saturated and should be replaced. Visual inspections and scheduled replacement intervals can also be used.
