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.

Helps Trap Airborne Particles

Forms a protective gel barrier inside the nose to help trap pollen, pollution and airborne droplets at the point of entry. 

(Tested in a 60-minute lab tissue model)

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.

what can norizite help trap?

Pollen. Pollution. Airborne droplets.

 

NoriZite forms a thin gel barrier inside the nose — your body’s first point of contact with the air you breathe. The barrier is designed to help trap airborne particles, including pollen, pollution and virus-carrying droplets, before they travel deeper into the airway.

 

In cell-culture testing, treated cells showed reduced infection across a panel of respiratory viruses, including SARS-CoV-2 variants, 

influenza A and B, RSV and rhinovirus.

 

Add nasal barrier protection to your daily routine.
