Summary: Nasal Wash Guide

A nasal wash is a way to clean the nasal passages and sinus cavities. It's a simple procedure that most people, even children, can do easily.


Benefits of a Nasal Wash

  • Reduces allergies by removing allergenic particles

  • Removes bacteria and viruses to decrease infections

  • Removes mucus so nasal medications work better

  • Reduces nasal swelling and increases airflow

  • Reduces dryness and irritation


When to Clean your Nasal Passages

  • During the allergy season the pollen from trees, grasses and weeds is heavy in the air.

  • Year-round to prevent infections.  Bacteria and viruses thrive in warm and moist environments, the nose being one of them.  Wash away those germs so they don't have a place to call home.

  • At least one hour before bed.  This can help you breathe better and more deeply.


How to do a Nasal Wash

  • Prepare the water according to CDC guidelines to avoid bacterial contamination*

  • Do the nasal wash leaning over a sink or basin

  • Blow your nose several times to completely remove mucus

  • Enjoy the benefits of a clearer nose

  • Don't forget to clean your nasal wash equipment after each use
