eN-eN Furniture is a well-known furniture manufacturer based in Moerkapelle, the Netherlands. Since 1998, they’ve built a strong reputation for creating stylish, high-quality furniture for the business market. With over 25 years of experience, they’re known for combining craftsmanship with flexibility and reliability. All woodworking is done in their own workshop, using a wide range of materials like chipboard, plywood, stainless steel, Corian, PET felt, and glass.
In the process of making furniture, a lot of fine dust is generated. Some of this dust is visible, but much of it isn’t—and that’s where the real risk lies. Fine dust, especially hard wood dust, is known to cause serious health concerns, including respiratory issues that may arise from prolonged exposure.
eN-eN Furniture wanted to ensure that their employees work in a safe and healthy environment. To do that, they first needed to understand how much fine dust was present in their production hall. They also wanted to ensure that these levels remained well within the national occupational safety norms.
Testing was performed in accordance with standard protocols, followed by the issuance of an independent verification report. Between 10 December and 18 December 2024, detailed air quality measurements were taken at two key spots in the hall: one between the machines near the format saw, and another between the workstations in the back section. Real-time DustTrak monitors and gravimetric sampling equipment were used to measure the levels of fine dust in the air.
The results showed that on several days, the amount of fine dust in the air was above the target value of 0.2 milligrams per cubic meter (mg/m³) for an eight-hour workday. The highest reading near the machines was 0.62 mg/m³. While this was still below the legal limit of 2 mg/m³, it was clear that the air quality could—and should—be improved.
To address the fine dust problem, eN-eN Furniture chose to install StaticAir’s PMR Tube air purification systems. These were set up to work quietly and efficiently in the background, constantly reducing the amount of dust in the air without interrupting daily work.
Specifically, the setup included:
Two PMR Tube units of 3 meters, placed near the machines where most dust is generated.
Two PMR Tube units of 5 meters, positioned to cover larger work areas and assembly zones.
These systems are low-maintenance and designed to pull fine dust out of the air using innovative technology that captures particles without blocking airflow.
To keep track of how well the system was working, the DustTrak monitors and gravimetric sampling equipment remained in place for ongoing measurement. This allows eN-eN Furniture to monitor improvements and stay on top of air quality over time.
Since installing the PMR Tubes, early results have shown a noticeable drop in fine dust levels. Real-time data from the DustTrak monitors shows that air quality is improving and moving closer to the target value of 0.2 mg/m³ for an eight-hour workday.
The PMR Tubes have not only helped reduce the amount of dust in the air, but they’ve also helped create a healthier and safer environment for everyone working in the hall.
Before the PMR Tubes were installed, fine dust levels often went above the target, especially on busy days. On 13 December 2024, for example, the PM10 concentration near the machines reached 0.62 mg/m³. Even on quieter days, it was common for the readings to exceed 0.2 mg/m³. In addition, more than half of the dust was made up of very small particles (PM1), which can go deep into the lungs and pose greater health risks.
After the installation of the PMR Tubes, the situation has started to improve. The amount of fine dust in the air is coming down, helping eN-eN Furniture move towards their goal of a cleaner and healthier workplace.
