@lilianna I typically purchase the product in a drugstore or larger grocery store but you can also order through Amazon. I always stock up when it is on sale in a pharmacy. As I’ve said, it is more expensive than the saline packages. The squeeze bottle version help, but if someone has an upper respiratory infection or thick mucus, the full stream option works, even if used now and then.

I purchase hydraSense, Daily Nasal Care Full Stream, strength. It is available in medium strength too. The box is a sea blue colour with red and white descriptions.

The other point I’d make is that it is a convenient nasal care product for travel. Hope that helps.
