Passive Filtration
HEPA Filters
High-efficiency HEPA filters designed for critical air filtration applications where the highest levels of particulate removal are required. Suitable for use in commercial, industrial and specialist environments, HEPA filters effectively remove fine airborne particles, including dust, bacteria and other contaminants, helping to maintain clean air conditions and protect sensitive processes and equipment.
HEPA filters are available in a wide range of standard enclosure sizes to ensure correct fit, effective sealing and reliable performance across common filter housings. Where standard options are not suitable due to enclosure design, airflow requirements or project-specific constraints, bespoke, site-safe HEPA filter sizes can be accommodated. Please contact the team to discuss your requirements and we will advise on the most appropriate solution.
Our technical team can support you with HEPA filter selection, enclosure compatibility and guidance on relevant standards and specifications. Speak to one of the team to discuss your HEPA filter requirements or to get advice on the most suitable HEPA filtration solution for your project. Browse our other filtration options: carbon filters, bag filters, pleated panel filters.

Understanding System Performance in Real Applications
How it's works
Air passes through dense HEPA media where fine particulate is captured via diffusion and interception, delivering high-efficiency filtration before air is discharged or recirculated.
