To keep our clients informed and safe, we are providing information on a recent recall notice from 3M™. If you are using these products, please read this announcement and follow the steps provided.

3M™ recently issued a notice to immediately stop using TR-6510N and TR-6530N Cartridges. These cartridges are used with the 3M™ Versaflo™ TR-600 and TR-800 Powered Air Purifying Respirators (PAPRs).

The reason for the stop and return announcement was based on 3M™ internal testing which showed that they may not pass the NIOSH requirements for HEPA particulate filters of at least 99.97% filtration efficiency. The TR-6510N and TR-6530N cartridges of concern may have a filter penetration of up to approximately 2% (filter efficiency of approximately 98%), which is below the relevant NIOSH requirements. The gas and vapor portion of these cartridges continues to meet the NIOSH requirements.

3M™ asks that you please review your inventory immediately to determine if you have affected product. If you have any of the affected product in question, please visit: for return and replacement.

Please note that this stop use and return notice applies only to the 3M™ TR-6510N and TR-6530N cartridges and does not affect any other 3M™ powered air-purifying respirator (PAPR) cartridges, filters, components, or assemblies/kits.
