How do you wear the O2 Nose Filters?
- With clean hands remove the filter from the travel case.
- Gently place the filters in the nose with the curvature facing towards you. Feel free to adjust the angle and depth in each nostril for optimal comfort.
- Enjoy cleaner air and easier breathing!
To remove the filters, gently pull the connecting band. Do not use if this is broken.
For best results, we recommend blowing your nose prior to inserting your O2 Filters.
What size am I?
Once you have the right size, the filter will conform to the inside contours of your nose to maximize comfort and protection.
How long can I wear O2 Nose Filters?
Can I use my O2 filters more than once?
O2 filters protect my nose but what about my mouth?
Do O2 Nose Filters prevent snoring?
Are the O2 Nose Filters Drug Free?
We recommend they be worn as a preventative measure against the symptoms of airborne allergens and pollutants.
Where can I buy O2 Nose Filters?
Bulk packaging for professional and industrial use is also available. If you are interested please email us at firstname.lastname@example.org
Why should I wear O2 Nose Filters?
- Pollen, pet dander, and other allergens
- Viruses and bacteria
- Industrial and automotive pollution
- Dust and spores
Where should I use O2 Nose Filters?
- When you are around allergens that effect you like pollen, grass, or pets
- In cities or environments with a lot of air pollutions
- In work environments where there is dust and debris in the air
- Traveling on an airplane, train, bus, or any crowded space where you want to protect yourself from the viruses and germs of the person coughing nearby
- Anytime you are using cleaning products
- At the dentist so you don’t breathe in everything the drills and lasers are aerosolizing
- Anytime you visit places like hospitals where there are sick people
- Police, military or anyone who shoots at a gun range and is concerned about breathing in the lead dust in the air
- Hospital and dental professionals, aid workers, construction workers, etc.
What is the difference between O2 and nasal strips?
Why is O2 better protection than wearing a surgical mask?
Surgical masks also:
- Are not discreet to wear in public
- Do not provide a complete seal
- Are warm and uncomfortable
- Inhibit conversation as they muffle the voice of anyone wearing it
Should dental professionals and patients consider wearing O2 Nose filters?
It is likely that the use of ultrasonic scalers is the most significant source of airborne microbial contamination. Numerous airborne particles derived from blood, saliva, tooth debris, dental plaque, calculus and restorative material are produced by an ultrasonic scaler when used in combination with water spray. The level of aerosol contamination during this type of treatment is three times higher than during other dental treatments.
Aerosols don’t just stay in the operatory. They travel throughout the entire office. Everyone in a dental office is breathing air contaminated by microbes, detergents, solvents, particulates, and metals.

Is O2 a better option for construction workers than disposable face masks?
O2 nose filters offer substantially better protection than disposable masks, are comfortable, don’t inhibit conversation, and are practically invisible. Workers greatly prefer O2 versus traditional disposable masks, thus compliance dramatically improves.
Breathing protection only works if users wear it.
What size particles will the O2 filters protect me from?
- Pollen varies from 10–100 microns, filtration efficiency is 90–100%.
- Pet Dander varies from 1–9 microns, filtration efficiency is 45–90%.
- Bacteria varies from .1–10 microns, filtration efficiency is 25–90%.
- Mold Spores vary from 10–30 microns, filtration efficiency is 90–100%.
- Saw Dust varies from 30–600 microns, filtration efficiency is 99–100%.
- Smog varies from .01–10 microns, filtration efficiency is 15–90%.
- Diesel exhausts vary from .05–1 microns, filtration efficiency is 25–40%.

What size particles are considered to be hazardous for humans?
• Thoracic Dust: Particles that will pass through the nose and throat, reaching the lungs. Particles of 10 microns diameter and less. Referred to as PM10 in the USA.
• Respirable Dust: Particles that will penetrate into the gas exchange region of the lungs. A hazardous particulate size less than 5 microns. Particle sizes of 2.5 micron (PM2.5) are often used in USA
What is the “Condensation Effect” and how does it help O2 nose filters become even more effective?
As they absorb water, the very smallest particulates increase their perceived size by at least 80%. As they continue to absorb moisture their size can increase to more than 1000% of their original dry size. For example, a particle that is 2.5 microns when dry will be filtered wet at a minimum of approximately 4.5 microns in size and can become far larger.
This “Condensation Effect” significantly increases the effectiveness of the 3M filtration material by enlarging the size of particles that otherwise would pass through more easily. Airborne viruses and bacteria (2 microns and larger wet) need moisture to live and are released into the air in water droplets, often via sneezing and coughing.
