After years of research, Nasopure has been able to provide an FDA registered, patented & proven nasal saline wash solution for unpleasant sinus problems. The comfortable patented BPA free bottle means that you can control the pressure & flow of your nasal saline wash unlike the neti pot & other sinus flushes which simply flood your system without restrictions. The Nasopure® nasal irrigation system removes allergens & any harmful bacteria around the nasal opening as opposed to a “sinus flush.” As a result you can experience an effective & comfortable cleanse without the discomfort & potentially dangerous infections that come with other sinus flushes.
