How to Clean and Sanitize Nasal Cannulas: A Step-by-Step Guide for Safe Oxygen Therapy
Maintaining clean and hygienic oxygen delivery equipment is vital for everyone relying on supplemental oxygen—whether adults, children, or newborns. Nasal cannulas, including the 4-foot, 7-foot (soft and pediatric), and 25-foot varieties, are the most common interfaces, and keeping them sanitized ensures your safety, comfort, and overall health.
If you’re using any of the following:
- 4-Foot Soft Cannula
- 25-Foot Cannula
- 7-Foot Soft Cannula
- 7-Foot Neonatal Cannula
- 7-Foot Pediatric Cannula
…you’re in the right place. You can also explore our full collection of oxygen accessories on our Buy Oxygen Accessories page.
Why Sanitize Your Nasal Cannula?
- Prevent Infections – Bacteria, mold, and other pathogens thrive in moist environments like oxygen tubing.
- Ensure Effective Oxygen Delivery – Buildup of debris can impair airflow.
- Enhance Longevity and Comfort – Clean surfaces are softer, reducing irritation on the nose and face.
Supplies You’ll Need
- Mild dish soap (fragrance-free, dye-free)
- Warm (not hot) water
- A clean basin or sink
- Clean, absorbent towels
- Hydrogen peroxide (optional, for deeper sanitization)
- Optional: Vinegar solution (1 part vinegar to 3 parts water)
Step 1: Remove the Cannula
Gently disconnect the cannula (4-Foot Soft Cannula, 7-Foot Soft, 7-Foot Neonatal, 7-Foot Pediatric, or 25-Foot Cannula) from the oxygen source. Avoid stretching or bending the tubing to maintain its integrity.
Step 2: Clean with Soap and Water
- Fill a basin with warm water and add a drop of mild dish soap.
- Swish the cannula gently in the soapy water to remove oils, particles, and dust.
- Pay extra attention to the prongs—use your fingers or a soft cloth to wipe lightly.
Step 3: Rinse Thoroughly
Rinse the cannula under running warm water until all soap is gone. Let water flush gently through the tubing to clear residue.
Step 4: Optional Disinfection (Weekly Deep Clean)
For a deeper sanitize—especially for infants or those with compromised immunity—try:
Hydrogen Peroxide Method
- Mix 1 part 3% hydrogen peroxide with 2 parts water.
- Soak the cannula for 10 minutes.
- Rinse thoroughly with warm water.
Vinegar Method
- Mix 1 part white vinegar with 3 parts water.
- Soak the cannula for 15 minutes.
- Rinse thoroughly before reuse.
Tip: Avoid bleach or harsh disinfectants—they can damage plastic and irritate skin.
Step 5: Dry Completely
- Shake out excess water.
- Lay flat on a clean towel, untwisted.
- Air-dry fully in a ventilated space away from direct sunlight.
Step 6: Reattach and Store Properly
Once dry, reattach your cannula carefully, avoiding sharp bends. If traveling, coil loosely for storage. To keep spares ready, visit our Oxygen Accessories page.
