The Purpose:

Discreet + Effective Protection Against Harmful Particulate Matter

By combining 3M’s innovative filtration science with O2’s elegant design, we’ve created the most discreet and effective solution to protect you from breathing in airborne pollution, allergens, viruses and more.
The Science:

3M Electrostatic Technology

Read More
Several layers of electrostatic materials capture particles like a magnet – as pollutants adhere to the filters, the charged area increases and enhances its filtration.
Filtration Statistics
The filtration efficiency of the O2 Nose Filters varies based on the size and speed of the particles – testing has demonstrated better than 70% efficiency at PM2.5 and over 90% at PM10.
The Design:

Discreet, Lightweight + Comfortable

In-Nose Fit
The discreet design allows you to wear the filters wherever you go, without inhibiting your communication or style!
Latex + Drug Free

Made from soft, medical grade TPE (Thermoplastic Elastomer) the O2 Nose Filters are comfortable to wear and latex free.

O2 Nose Filters are worn as a preventative measure against breathing in potentially harmful particulates. There is no medication or drugs in our filters.

All Day Protection,
In All Environments

From Airborne Pollution, Allergens, Viruses + More
12-Hour Protection

The O2 Nose Filters are designed for one-time use up to 12 hours, the discreet and comfortable design lending to undisturbed, all-day wear and protection.

Travel Optimized

All O2 Nose Filters come with a small travel case, so you can always keep a pair or two in your pocket or bag. Wearing nose filters while traveling on public transportation above or below ground will help to protect you and keep you healthy from point A to point B.

PM10 and PM2.5

O2 Nose Filters effectively capture harmful particulates of PM10 and PM2.5 – including but not limited to pollution, pollen, viruses, dust, ash, and some motor vehicle exhausts. Read more specifics here.

“After wearing the O2 Nose Filters for eight hours in the city they are a dark grey. I can see they work and feel my breathing in the evening is considerably lighter than before I started to use them a few months ago.”
