HF EtO air cleaner
Ethylene oxide (EtO) is a harmful gas that is widely used for sterilizing medical products. During storage, it can continue to be released for months from the cardboard packaging and from underneath the plastic film. This release happens gradually, and because the gas is invisible and has a high odor threshold, concentrations in warehouses can build up significantly.
Legal framework
EtO is classified as a CMR substance: Carcinogenic, Mutagenic, and Reprotoxic. Due to its severe health effects, there is no safe threshold for exposure. In the Netherlands, a legal occupational exposure limit of 0.46 parts per million (ppm) or 0.84 mg/m³ applies as an 8-hour time-weighted average (TWA). However, employers are responsible for ensuring a safe working environment and are legally obliged to minimize exposure to CMR substances such as EtO as much as possible, even when levels remain below the limit value.
Why air filtration is important
Ventilation and filtration are important methods for reducing EtO levels in indoor environments. A proper supply of fresh air helps to prevent the formation of local concentration peaks (hotspots). However, the extraction of air to the outside and recirculation are subject to strict regulations, depending on local legal and environmental requirements. Air filtration is an attractive alternative, especially when ventilation alone is insufficient. Moreover, it is virtually energy-neutral, as it does not add extra heating or cooling load to the indoor climate.
HF EtO
The HF EtO is an advanced air cleaner specifically developed for the safe removal of ethylene oxide (EtO, C₂H₄O) from indoor air in industrial, logistics, or medical environments. This unit combines multiple filtration and oxidation technologies in one powerful and scalable system, and is designed with a focus on safety, effectiveness, and reliability.
Multiple phases
Depending on the EtO concentrations and your air quality objectives, we offer customized solutions with various airflows and filtration configurations. The proposed solution is tailored to the usage profile, budget, and desired level of reduction.
In the first stage, an electrostatic filter removes airborne particles such as fine dust, cardboard fibres, and rubber residues. This helps meet air quality goals related to particulate matter while protecting subsequent filter stages from premature saturation, extending system performance and lifespan.
In the next stage(s), various options are available for advanced gas removal. We use CKV3 and Kinetic 425, specially selected filtration media optimised for EtO adsorption. Air passes through these adsorption layers, where ethylene oxide is safely and effectively captured.
Preventing hotspots
The integrated fan of the HF EtO draws in air from the rear of the unit and propels the purified air back into the room through a triple-outlet discharge system. This design is engineered to enhance air circulation, minimize dead zones, and prevent hotspots.
Measurement solutions for ethylene oxide
Reliable data is the foundation of an effective mitigation plan. Depending on the situation, we collaborate with independent specialized partners to provide spot measurements and long-term monitoring. The collected data provides insight into risks, priorities, and supports well-founded decisions. Measurement results are accessible in real time via an online portal.
For more in-depth analysis, air sampling with laboratory analysis is available. This method delivers highly accurate results and is often used for validation or legal documentation. It ensures reliable data to minimize exposure and comply with the duty of care under the ALARA principle.
What can you expect from the HF EtO?
- Effectively removes ethylene oxide – proven and reliable
- Advanced filtration systems for industrial applications
- Improved air quality in logistics halls, sterilization facilities, and production environments
- Reduced health risks for employees
- Compliance with safety and environmental regulations
Step-by-step plan for a safe working environment
No two situations are alike when it comes to EtO. Every work environment has its own challenges, risks, and objectives. That’s why we guide companies step by step toward a structurally safe working environment, in close collaboration with a network of independent experts. This process is tailored to your specific needs and consists of four key phases.
Quick scan
We start with an exploratory visit to assess the situation. Based on observations, we identify potential risk zones and determine where measurements will be most meaningful.
Detailed measurements
Actual EtO concentrations are measured in this phase. The data provides the foundation for analysis, identifying peaks, dispersion, and trends over time.
Risk assessment (RI&E) considerations and definition of ambitions
The measurement results are translated into concrete objectives. Together, we establish realistic reduction targets and priorities, aligned with legal standards and your business goals.
Detailed design and implementation plan
Based on measurements and objectives, we design a customized filtration and monitoring solution. We also advise on maintenance, periodic validation, and continuous improvement in line with the ALARA principle.
