High Efficiency Particulate Airborne (HEPA)


Continental Carbon Group stocks HEPA filters that handle airflow up to 2,000 scfm, and a minimum efficiency of 99.97%. All HEPA filters are designed for seamless installation in all Continental Carbon Group equipment. It is recommended that HEPA filters be preceded by a prefilter to capture larger particles and increase HEPA life.

HEPA filters are typically required for use in:

  • Hospitals
  • Pharmaceutical manufacturing
  • Clean rooms
  • Computer rooms
  • Nuclear ventilation systems
  • Laboratories
  • Research facilities
  • Food processing plants


A prefilter is the primary layer of filtration that collects large particles before they reach the HEPA filter. They are designed with a low pressure drop and are often changed more frequently than the HEPA filters in the system. The primary advantage of the prefilters comes from extending the life of the expensive HEPA filters and gas/odor cartridges by preventing dust from coating and clogging the HEPA filters. Prefilters can be made of either fiberboard, galvanized or aluminized carbon steel.

Continental Carbon Group is constantly striving to improve its products and capabilities and to provide the best product to it customers.

Continental Carbon Group may from time to time develop product improvements or alterations (including, without limitation,

revisions to product specifications), and may implement such Product Improvements without notice to the Buyer.

Making Air Safer and Cleaner


Wet activated carbon removes oxygen from air, causing a severe hazard to workers inside carbon vessels. Confined space/low

oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable local,

state and federal guidelines.
