How NoriZite Works

1. Spray

Title

A fine mist spreads gently across the nasal lining.

2. Plume-to-Gel

Title

The mist rapidly becomes a soft fluid-gel layer on contact with the moist lining.

3. Trap and Clear

Title

The gel layer is designed to help trap airborne particles, supporting your nose's natural  clearance processes.

why soft-matter bio-barriers?

A barrier only helps if it covers enough surface area and stays in place. 

Many conventional sprays struggle with this trade-off: stronger formulations often spray as a narrow jet and cover less area.

Soft gel layer

Designed to form a soft gel layer on the nasal lining. (Lab model data; not a measure of real-world trapping.)

Covers Where It Matters

Designed to spread across the nasal lining for better surface coverage than conventional sprays.

(In-vitro coverage study vs. conventional sprays)

Stays With You for Hours

Made for commutes, flights, crowded spaces and pollen season — when your nose needs extra support.
