From the creators of ifD® – the technology that challenged HEPA worldwide

Introducing
Kobros Logo

Permanent, high-efficiency particle collection with low pressure drop, low-to-no maintenance, and no replacement filters.

Darwin Technology International is a UK-based research and development company with nearly 30 years of experience developing advanced, high efficiency air filtration technologies for global manufacturers. Its technologies, including the widely deployed ifD® platform, have been integrated into millions of products worldwide.

NEW: Kobros® — Our Latest Breakthrough

Kobros, Darwin’s latest particle collection technology, is designed to maintain high efficiency filtration over extended operating periods with low pressure drop, no replacement filters and virtually no maintenance.

By eliminating dense media and disposable filters, and avoiding the efficiency decline typical of conventional electronic air purifiers, Kobros sustains real-world air cleaning performance while reducing maintenance, extending product life and avoiding the ongoing environmental burden of producing, transporting and disposing of replacement filters.

The result is improved PM2.5 air cleaning performance, lower lifetime cost of ownership and a more sustainable approach to high-efficiency air filtration.

Virtually Maintenance FreeDesigned for extended operation with minimal intervention

No Replacement FiltersEliminates ongoing consumable costs

Low Pressure DropEfficient, quiet performance for multiple applications

Slimline IntegrationEnables compact, quiet system designs

High Efficiency Sub-micron capture at and below 0.3 microns.

Beyond the Limitations of Traditional Filters

The performance of conventional filtration technologies degrades over time, either through airflow restriction or reduced particle capture efficiency. Kobros is designed to maintain consistent performance across both dimensions and provide long-term, low-maintenance performance:

HEPA Filters

  • Good initial CADR*
  • Regular filter replacements
  • CADR drops as the filter clogs over time
  • High pressure drop

Electronic Filters

  • No filter replacements
  • CADR drops as efficiency declines over time
  • Requires regular cleaning

Kobros®

  • Consistent high CADR
  • Virtually no-maintenance
  • No filter replacements
  • Slim profile design

* CADR (Clean Air Delivery Rate) is a practical measure of air cleaning performance, indicating how much clean air a filtration system delivers by combining airflow with particle removal efficiency.
