## Questions & Answers

**Q: What is the correct size for a small 120 pound woman?**
A: Probably a small but mask sizing depends on your facial features and what works best for you.

**Q: What are the measurements  sizes of medium and large?**
A: Unfortunately there are no simple measurements to take or easy guidelines to follow when selecting respirator size. In our experience, a medium may fit a majority of the adult population, but a small or a large may be necessary depending on the wearer’s facial features. The only accurate way to determine correct size is to conduct a respirator fit test. The fit test is a specific OSHA-required protocol that tests the respirator seal to the face.
