The RAG Replaceable Filter Mask (RFM) is a Rapid Application Group design that uses initial design language of the NIH approved stop gap surgical face mask. Our design allows a user to source all materials in the United States that are readily available! The RFM improves comfort for long term use and issues deriving from prolonged plastic-to-skin contact. The implemented comfort seal allows for a complete seal around the face to pass fit check and extended use comfort. The RFM has completed multiple independent fit check tests and clinical evaluations to determine suitability. Rapid Application Group is a proud America Makes member.
The RFM consists of three components. (the mask body, the interchangeable filter frame, and the filter cover). Additional resources may need to be sourced locally including a 3/8” outside dimeter 1/4” inside diameter FDA approved food grade tubing that is 30-50 durometer for comfort and proper seal around the face.
The RFM was designed to be used with different filter media. Our fit testing was completed with sacrificial N95 mask and surgical squares. The RFM was designed to accept the optional quick-change filter cartridge or a trimmed down surgical or N95 masks.
This design was a collaboration of multiple players:

Dear author,
Your design has undergone clinical verification and is ready to be signed off. One change which needs to occur is the note regarding filter media. As the only filter media materials approved at this time are cut up surgical masks, we request you remove any mention of other N95 type materials until they have undergone proper validation. If you are aware of material which has completed such testing, please provide verified data regarding this in order to update this.
Once requested updates are complete we will be able to finalize your submission.
Thank you.
Sincerely,
VA REVIEW TEAM
