Choosing the right industrial air filtration system starts with knowing your particle risks
No two facilities produce the same type of airborne pollution. And not all industrial air filters are built for the same job. To choose the right industrial air filtration system, you first need to understand the particles circulating through your space, how they behave and what risks they carry for your people, equipment and compliance.
Know your particles – what are you breathing in?
What are coarse particles and where do they come from?
Coarse particles are larger, heavier dust particles released during forklift traffic, sweeping, sanding, and material handling. They settle quickly but accumulate fast on floors, shelves, stock and machinery – increasing cleaning costs, creating slip risks and accelerating equipment wear.
What is PM10 and why is it relevant in industrial environments?
PM10 refers to particulate matter with a diameter of 10 micrometres or less. These particles are usually produced by grinding, cutting, or powder handling. They stay airborne longer than coarse particles and can irritate eyes, throat and lungs – especially in facilities with poor ventilation or fluctuating production volumes.
What are PM2.5 particles and how do they affect air quality?
PM2.5 are fine particles that stay suspended for hours and penetrate deep into the respiratory system. Generated through combustion processes, high-speed machining and fine powder operations, these invisible particles are a major contributor to chronic health risks and poor indoor air quality ratings.
What are ultrafine particles (PM1) and why are they dangerous?
Ultrafine particles (PM1 and smaller) are the most harmful and nearly impossible to remove with basic filtration or extraction. Released from welding, laser cutting, diesel engines and chemical processes, these microscopic particles are small enough to enter the bloodstream, making high-class filtration essential for employee health, environmental control and audit outcomes.
Which industries produce the most hazardous airborne particles?
Most commercial and industrial environments generate airborne pollution, but the highest-risk settings typically include:
- Metalworking & welding
- Woodworking & joinery
- Food production & packaging
- Logistics & distribution centres
- Pharmaceutical & chemical processing
- Plastics & rubber manufacturing
Each industry produces a unique particle profile, which is why choosing the correct filter classes, materials, and industrial air filtration system is critical.
Which industrial air filters do you need for effective particle control?
Choosing the right industrial air filtration system isn’t just about the unit itself – it’s about the engineering and filter combination inside it. Different particles require different filter classes, materials and setups.
Here’s how Zehnder’s filtration technology removes airborne pollutants across industrial environments:
Flimmer filters use thousands of polypropylene fibres that naturally attract and hold onto particles, keeping your air cleaner without slowing your airflow. They can work alone or alongside pocket or compact filters and are especially effective in dusty environments. By capturing fibres and coarse dust early, they help your downstream filters last longer and keep your system running efficiently – a unique advantage available only with our patented FlimmerM® technology
Pocket filters (or bag filters) are designed for places where dust builds up fast. Their multiple pockets create a large surface area, so they can handle high dust volumes while still letting air move freely. Air flows in carrying particles and comes out clean on the other side. They can be used alone or combined with other filters, either as pre-filters or downstream stages.
Compact and HEPA filters handle the finest, most stubborn particles, from PM2.5 to ultrafine PM1 dust and smaller created by welding, food processing, pharmaceuticals or precision manufacturing. They work as supportive air purifier filters and can be supplied in a range of filter classes, all the way up to HEPA 14. Designed for environments where clean air can’t slip, they provide the final filtration stage for stable airflow, compliant air quality and consistent production results.

Full control of your industrial air filtration – wherever you are
Zehnder’s industrial air filtration systems don’t just clean the air – they think for themselves. Zehnder CARA (Clean Air Remote Application) gives you real-time visibility, intelligent automation and long-term performance inisght into your particle levels and filter efficiency. It’s clean air control made simple, from any location.
CARA gives you a complete overview of your industrial air filtration system at a glance. The dashboard displays current CADR values, air cleaning efficiency, filter status and energy usage. Historical data is stored and easy to access, making reporting, compliance tracking and optimisation far more straightforward. Whether you’re managing one industrial air filtration unit or an entire network across multiple sites, everything you need is in one clear, intuitive interface.
CARA gives you a real-time view of what’s happening in your facility’s air, right now. Its built-in sensors continuously track airborne particles across multiple size ranges, from coarse dust to PM10, PM2.5 and PM1.
You can see live dust performance, airflow levels, filter status and particle trends as they happen, so you always know how your industrial air filtration system is behaving at any moment. No guesswork. No waiting for reports. Just clear, instant visibility.
Zehnder filtration systems learn how particles behave in your environment. When dust concentrations rise, airflow and filtration intensity increase automatically. When levels stabilise, the system reduces output to save energy and extend filter life. The result: cleaner air at a lower operating cost, without the need for constant manual adjustments or technical oversight.
