All-Day, Discreet Air Protection

Protego O2 Nose Filters offer a lightweight, drug-free way to manage everyday exposure to airborne particles. Designed as an invisible shield, they’re suitable for busy days at the airport, on public transit, or in city streets where pollen, dust, and smoke are present. The goal is to help you breathe easier as you go about your day.

How the filtration works

Engineered with premium 3M media, these nasal dilators use electrostatic technology to capture tiny particles. They can help reduce exposure to particles as small as 2.5 microns, supporting a cleaner breathing environment as you move through different environments.

• Advanced filtration using trusted 3M media
• Electrostatic capture for small particles
• Lightweight, latex-free design for everyday wear

In practice, you may notice a lightweight feel, minimal heat buildup, and less interference with glasses compared to heavier options. This makes them suitable for airports, offices, and crowded indoor spaces where air quality varies.

Fit, comfort, and care

The nose vents are crafted from soft, surgical-grade plastic and come in five sizes to suit most noses. For those unsure of fit, a convenient trial pack offers four sizes to discover your best match. Replace the nose filter every 8 hours to maintain comfort and performance.
