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, and more.

The Science:

3M Electrostatic Technology

Filters 90% of harmful airborne particles at PM10 and 65% at PM2.5
Read More
Several layers of electrostatic materials capture particles like a magnet. As particles adhere to the filters, the charged area increases and enhances its filtration capabilities.
Filtration Statistics
The filtration efficiency of the O2 Nose Filters varies based on the size and speed of the particles. Testing has demonstrated 65% efficiency at PM2.5 and 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 Thermoplastic Elastomer (TPE), the O2 Nose Filters are comfortable to wear and are latex-free.

O2 Nose Filters are intended as a preventative measure against breathing in potentially harmful particulates. They do not contain any medication and are not intended to be a replacement.

All-Day Protection,
In All Environments

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

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

After a full day of use, or when the filter material is visibly dirty, please recycle with other soft plastics.

Travel Optimized
Our O2 10 Packs and 3 Packs come with a small travel case, so you can always keep a pair or two in your pocket or bag. Wearing O2 while traveling on pubic transportation (above or below ground) will help protect your from breathing in harmful airborne particles like exhaust, pollution, dust, bacteria, viruses, and pathogens – keeping 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.

“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.”

“I have my kids wearing the filters as I take them for long strolls in the city and city parks. My son has stopped wheezing now most evenings. For my little girl I feel good knowing it’s precautionary. Thank you!”

Marianne V

Mother, London

“Wearing nose filters has changed the way I live! I have always suffered from Hayfever but been unable to take any mediation due to my profession. I now feel my so much more comfortable in nature during the Spring and Summer months and feel much freer and confident to coach.”
