## Questions & Answers

**Q: Do the filters have the foam cushion for the nose?**
A: Yes.

**Q: Are they n95 or n99?**
A: They have not yet received niosh approval, but have completed testing to the n99 standard.

**Q: Do these come with replacement one-way valves? Or are they just the inner filter?**
A: This is just the filter. Replacement valves can be purchased separately.

**Q: Do large RZ2 filters fit the medium mask or must I buy medium filters?**
A: You should use the medium filters in a medium mask to achieve the best fit. You may notice excess material at the top or bottom of the mask if you use a large filter in the medium mask.
