flo Sinus Care Refill 100 Sachets | Nasal Cleansing, Relieves Nasal Allergies, Alleviates Nasal Congestion and Sinusitis, Gentle and Non-Stinging, Made in Australia

In Hong Kong, air quality fluctuates, and the frequent temperature changes between air-conditioned rooms and the outdoors cause many people to suffer from nasal congestion, nasal allergies, and sinusitis. During seasonal changes, peak pollen periods, or even just daily exposure to dust and pollutants during commutes, nasal discomfort and obstructed breathing can significantly impact sleep quality and daytime productivity.

flo Sinus Care Refill, from Australia's professional nasal care brand, contains 1.8g of pre-mixed rinse powder per sachet. Ingredients include sodium chloride, sodium bicarbonate, potassium chloride, calcium lactate, and anhydrous glucose. When dissolved in 200ml of warm water, it forms an isotonic solution that closely matches the extracellular fluid of the human body, gently and deeply rinsing the nasal passages and sinuses. It effectively removes allergens, bacteria, and excess mucus. Use twice daily for noticeably clearer breathing.

🌿Why choose flo Sinus Care Refill? Australia's #1 selling nasal rinse solution

In urban life, the following situations are subtly affecting your nasal health:

  • Working long hours in air-conditioned rooms, leading to dry and easily irritated nasal membranes
  • Exposure to car exhaust, construction dust, and various air pollutants during commutes
  • Significant increase in allergens such as pollen and dust mites during seasonal changes
  • Persistent nasal congestion after colds, with mucus blocking sinuses causing discomfort

flo Sinus Care Refill addresses these common urban nasal problems with its large-volume, low-pressure rinsing technique, providing the following core benefits:

  • ✅Deeply cleanses nasal passages and sinuses: Thoroughly rinses with 200ml large-volume solution, covering a wider area than traditional nasal sprays
  • ✅Soothes nasal allergy symptoms: Effectively washes away allergens such as pollen, dust mites, and pet dander
  • ✅Relieves nasal congestion and sinusitis: Removes excess mucus and bacteria, reducing sinus pressure and discomfort
  • ✅Gentle and non-stinging: Isotonic formula mimics the body's extracellular fluid, free from medication and preservatives
  • ✅Suitable for the whole family: Can be used by adults and children aged 4 and above, also suitable for pregnant and breastfeeding women

🔬How does the product work? Clears breathing from the inside out

The formula of flo Sinus Care Refill is specifically designed to be an isotonic solution that mimics the extracellular fluid of the human body, through the synergistic action of five natural mineral salts:

  1. Sodium Chloride — Primary salt component
    • Forms isotonic osmotic pressure, compatible with nasal mucous membrane tissue
    • Effectively dissolves and removes viscous secretions in the nasal cavity
    • Helps maintain a normal moist environment in the nasal cavity
  2. Sodium Bicarbonate — pH balancing agent
    • Adjusts solution pH to near human physiological levels
    • Reduces irritation and discomfort during rinsing
    • Enhances the mucus-dissolving capability of the solution
  3. Potassium Chloride — Electrolyte supplement
    • Supplements potassium ions needed by nasal mucous membrane cells
    • Supports the normal ciliary movement function of the mucous membrane
  4. Calcium Lactate Pentahydrate — Calcium ion source
    • Helps maintain the integrity of nasal epithelial cells
    • Supports the natural barrier function of the mucous membrane
  5. Glucose Anhydrous — Cell nutrient
    • Provides immediate energy source for nasal mucous membrane cells
    • Promotes the natural repair process of mucous membrane tissue

These five ingredients work together to make the rinse solution's composition similar to the body's own extracellular fluid, thus preventing stinging or burning sensations during use. This makes it superior to ordinary saline and sea salt solutions, suitable for daily long-term use.
