Dr. Hana's Nasopure Nasal Wash System offers an affordable and safe method for relieving allergies and sinus pain. After years of research, Nasopure has been able to provide an FDA registered, patented and proven nasal saline wash solution for unpleasant sinus problems. The comfortable patented BPA free bottle allows you to control the pressure and flow of your nasal saline wash unlike the neti pot and other sinus flushes which simply flood your system without restrictions. The Nasopure nasal irrigation system removes allergens and any harmful bacteria around the nasal opening as opposed to a sinus flush. As a result you can experience an effective and comfortable cleanse without the discomfort and potentially dangerous infections that come with other sinus flushes.
