Nasal Irrigation Guide: How to Use a Neti Pot & Sinus Rinse Safely
Nasal irrigation is an evidence-based therapy for managing chronic sinusitis, allergic rhinitis, and nasal congestion. In Canada, where seasonal allergies affect over 8 million people and sinusitis accounts for millions of healthcare visits annually, proper nasal irrigation technique is essential for safe and effective symptom relief. This guide covers device types, saline preparation, step-by-step instructions, and critical safety warnings.

Saline Solution Preparation
Using the correct saline concentration and water quality is critical for safety:
- Distilled, sterile, or previously boiled water must ALWAYS be used. Tap water contains microorganisms (including Naegleria fowleri) that can cause fatal infections if introduced into the nasal passages.
- Premixed packets (e.g., NeilMed® Sinus Rinse™ packets) contain USP-grade sodium chloride and sodium bicarbonate for isotonic or hypertonic solutions.
- Isotonic solution: Mix 1 packet in 240 mL water — matches body fluid salinity, gentle for daily use.
- Hypertonic solution: Mix 2 packets in 240 mL water — draws fluid from tissues, better for severe congestion but may cause stinging.
- DIY recipe (if premix unavailable): 1 tsp non-iodized salt + 1/2 tsp baking soda in 500 mL distilled water. Do NOT use table salt (contains anti-caking agents and iodine).
Step-by-Step Nasal Irrigation Procedure
- Wash hands thoroughly with soap and warm water.
- Prepare the solution: Fill the device with distilled/sterile water at body temperature (lukewarm). Add the saline packet and shake or swirl to dissolve completely.
- Position yourself: Lean over a sink at a 45-degree angle with your head tilted forward. Do NOT tilt your head back — solution will run down your throat instead of through the nasal passages.
- Insert the spout: Gently place the tip of the neti pot or squeeze bottle against one nostril, creating a seal without forcing it deep into the nasal cavity.
- Irrigate: For neti pot, tilt the pot until solution flows into the nostril — it will drain out the other nostril by gravity. For squeeze bottle, squeeze gently and steadily. Breathe through your open mouth during irrigation.
- Alternate nostrils: Repeat on the other side. The solution should flow in one nostril and out the other without difficulty.
- Clear the nose: Gently blow your nose into a tissue to remove remaining solution. Do NOT forcefully blow — this can push fluid into the Eustachian tubes.
- Rinse the device: Wash the device with distilled water and soap, and air dry completely between uses.

Cleaning and Maintenance
- After each use: Rinse the device thoroughly with distilled water and mild soap. Air dry completely (microorganisms thrive in moisture).
- Weekly: Disinfect by boiling the device for 5 minutes (if heat-safe) or soaking in a 1:10 bleach solution for 1 hour, then rinsing thoroughly.
- Replace the device: Every 3 months, or sooner if cracks or clouding develop.
- Squeeze bottle care: Remove the cap and allow the bottle to dry completely upside down. Replace the bottle every 30 days.
Critical Safety Warnings
⚠ IMPORTANT SAFETY INFORMATION:
- NEVER use tap water for nasal irrigation — even with a filter. Only use distilled, sterile, or previously boiled (and cooled) water.
- Replace devices regularly — squeeze bottles should be replaced every 30 days, neti pots every 3 months.
- Do not share devices — this can spread infections between individuals.
- Use proper technique — tilting the head back or squeezing too hard can force solution into the Eustachian tubes, causing ear infections.
- Stop use if you experience: Ear pain, persistent nosebleeds, worsening symptoms, or signs of infection (fever, facial swelling).
- Consult a healthcare provider before starting nasal irrigation if you have had sinus surgery within the past 3 months, have a weakened immune system, or have chronic ear infections.
When to Use Nasal Irrigation
- Chronic sinusitis: Daily irrigation reduces symptoms and decreases reliance on antibiotics
- Allergic rhinitis: Flushes out allergens and reduces post-nasal drip
- Post-sinus surgery: Promotes healing by removing crusts and debris
- Canadian winter dry air: Moisturizes nasal passages and prevents nosebleeds
- COVID-19/general congestion: Provides symptomatic relief (not a treatment or preventive measure)
