A portable saline nasal spray is a device designed to remove allergens or other harmful substances from the human nasal cavity in effective and convenient way. The portable saline nasal spray includes a spray pump that is operated by a finger, a spray nozzle that is ergonomically designed to effectively spray into the nasal cavity, and a disposable saline pouch that can be purchased separately. Not like other existing method, instead of forcing the saline solution to flow though the nasal cavity, this invention sprays the saline solution effectively over the whole surface of the nasal cavity. Because saline solution is sprayed, it requires only small amount of solution for daily use. This invention utilizes factory prepared sterile saline solution contained in disposable pouch that makes the nasal cleaning procedure much more simple and convenient. Just one small pouch of saline solution can be used for a whole week of twice a day nasal cleaning. Furthermore, because it is designed to be a leak-free portable device, it would look nice to keep anywhere, and the user can even carry it in his/her most favorite bag and use it anytime at anywhere they want.
