Everyday use. Best applicator!
Great product for everyday use. One even better thing compared to others is the shape of the tip, as it allows you to better go into the nose.

About Stérimar Isotonic (Daily Nasal Hygiene)
What it is & how it helps
Stérimar Isotonic is a 100% natural seawater nasal spray with a salt concentration matched to your body's cells. That makes it gentle enough for everyday nasal hygiene, washing away dust, pollen and allergens, moisturising the nasal lining and helping you breathe more comfortably. It's drug-free, steroid-free and preservative-free, so it suits regular, long-term use.
When to use it
Use Isotonic for:
- Daily nasal cleansing and moisturising
- Removing dust, pollen and airborne allergens
- Relief from a dry or irritated nose
For a blocked, congested nose, the Hypertonic version is designed to decongest.
Isotonic or Hypertonic: which Sterimar do you need?
Both sprays are made from natural seawater. Choose Isotonic for gentle everyday cleansing, and choose Hypertonic when your nose feels blocked or congested.
| Spray | Best for | How it works |
|---|---|---|
| Sterimar Isotonic (this spray) | Gentle daily nasal hygiene and cleansing, suitable for all ages per the label | Seawater at a salt level close to the body's own fluids, so it rinses away dust, pollen and everyday irritants while moisturising the nasal lining |
| Sterimar Hypertonic | A blocked or congested nose from colds, allergies or sinus issues | A higher salt concentration than the body's fluids, which Sterimar formulates to help draw moisture from the swollen nasal lining and ease a stuffy nose |
If you are not sure which one suits you, ask your pharmacist.
How to use
- Tilt your head slightly forward.
- Insert the nozzle into one nostril.
- Spray while breathing in gently.
- Repeat in the other nostril, then blow your nose.
- Use 2-6 times a day in each nostril, for as long as you need.
