- Users of mesh or jet nebulizers who want preservative free unit doses
- No clinician has recommended hypertonic saline
- A doctor has recommended a different strength, such as 3% or 0.9%
- You have had chest tightness or wheezing with saline before and have not discussed it with a doctor
What owners like

- Clear directions on single use and storage
- Single dose vials avoid measuring or mixing
Common complaints
- Hypertonic saline can bring on coughing, throat irritation or wheezing in some users
- The maker's page does not state its prescription or regulatory status

What it does
A box of 50 single use 5 ml vials of sterile 7% salt water made for use in a nebulizer cup.
- Twist open vials poured straight into the nebulizer cup
- Only two ingredients, with no preservatives, stabilizers or fillers, per the maker
- Sterile single use format, with each vial discarded after use
- Works with standard and mesh nebulizers, including the maker's own mesh unit
This suits people whose clinician has already told them to use 7% saline and who want a simple, preservative free vial format. The main caution is that 7% saline is normally a prescription item, so the concentration and the first use should be cleared with a doctor rather than chosen from a shopping list.
