1. Aqua Maris Baby (for babies) Features: An isotonic seawater solution with the same osmotic pressure as body fluids. It features a very gentle spray nozzle designed to avoid irritating a baby’s delicate nasal passages. Target: Newborns to infants. For runny noses due to colds or allergies, and nasal dryness. How to use: 1–2 sprays in each nostril, 3–4 times daily, or as often as needed.

2. Aqua Maris Classic (for adults/daily care) Features: An isotonic seawater solution with the same osmotic pressure as body fluids. Supports daily nasal hygiene without placing a burden on the body. Target: Adults and children. For nasal dryness caused by air conditioning, early cold symptoms, and washing away PM2.5 or house dust. How to use: 1–2 sprays in each nostril (3–4 sprays if dryness is severe), as often as needed.

3. Aqua Maris Strong (for strong nasal congestion relief) Features: A hypertonic seawater solution with a higher salt concentration than usual. Through osmotic pressure, it draws excess moisture out of swollen nasal membranes, relieving congestion naturally without the use of medicinal ingredients (vasoconstrictors). Target: Children aged 3 and up, and adults. For severe nasal congestion due to colds, allergies, or influenza, or for post-nasal surgery care. How to use: 1–2 sprays in each nostril when feeling congested. It is not habit-forming, so it is safe for long-term use.
