Review: Relacment Cartridge - The product is just like the original equipment. It is not a generic nor an inferior product but the exact cartridge. Because I was happy with the original performance I was sure I'd be happy with the replacment. And indeed I was. It is working perfectly like the original equipment. Since I could not find a replacement at a local dealer & did not want to purchase a whole new unit, I was very happy to have found the replacement cartridge available on line
Review: Replacement filters - Product was corroded but seems to work fine. Seller assured me that these were new filters but I didn't think they should have been rusty. Probably won't buy them from this source again.

## Questions & Answers

**Q: Does anyone know how long these cartridges last?  Or, how to determine if they are still good for filtering and how to do that?**
A: I store my mask w/the filters in a zip lock bag, after I clean the mask inside with rubbing alcohol.  No idea how long they last, nor how to tell if they are bad.

**Q: R51a suitable for protection from mold spores**
A: it's not advertised for that. It's for paint and similar chemicals.  Click the link to the left for details from the masnufacturer.  There are air purifiers to deal with mold and probably masks.

**Q: Will these fit an r5700 mask? The image looks similar in the treaded bottom section, and the current canisters on the mask are r51he.**
A: yes

**Q: Can this be used to prevent ingestion of respiratory aerosols?**
A: These Cartridges are used for protection from Organic Vapors. These particular filters use Carbon to filter.
