Which type of water is recommended for sinus rinsing?

Always Use Distilled or Micro-Filtered (through 0.2 micron) or Commercially Bottled or Previously Boiled & Cooled Down Water at Lukewarm or Body Temperature.Rinsing your nasal passages with only plain water will result in a severe burning sensation. Use lukewarm distilled, filtered or previously boiled water, properly mixed with NeilMed's SINUS RINSE packets. Please do not use tap or faucet water for dissolving the mixture unless it has been previously boiled and cooled down. Do not rinse if nasal passages are completely blocked or if you have an ear infection or blocked ears. If you have had recent ear or sinus surgery, please contact your physician prior to irrigation. If you experience any pressure in the ears, stop irrigation and get further directions from your physician. Keep out of reach of children.
