Our Nose Filters are designed for up to 12 hours of use, however, in dusty or especially polluted environments, you may need to swap them out more often. It is important to use the right size for optimal comfort and protection, so make sure there are no gaps between the inside of your nostrils and the filters.

O2 Nose Filters are designed for one-time use up to 12 hours. We do not recommend re-using a filter as they can become contaminated.

The good news is that the acids in saliva affectively neutralize most of the air through your mouth. Your warm, moist nasal passages and sinus cavities are the most important place to protect, as this is where germs, viruses, and bacteria tend to lodge and multiply. Once you have your O2 Nose Filters in place, try to breathe through your nose as much as possible to take advantage of the protection they provide (plus nasal breathing is healthier for you too)!

O2 Nose Filters have been proven to reduce snoring in many cases as they open up the nasal passages and support the tissues in the nose.

Our O2 Nose Filters are not made with any drugs or medicine. We recommend they be worn as a preventative measure against the symptoms of airborne allergens and pollutants, but they are not a cure or a replacement for medications.

O2 Nose Filters are available on our website and Amazon, as well as in pharmacies and retail chains around the world.

Bulk packaging for professionals and industrial use is also available. If you are interested, please email us at [email protected].

There are harmful particles in the air we breathe. O2 Nose Filters capture up to 99% of all harmful airborne particles down to less than 2.5 microns in size. This means they protect against and provide relief from the symptoms caused by:

• Pollen, pet dander, and other allergens
• Viruses and bacteria
• Industrial and automotive pollution
• Dust and mold spores

The easy answer is “anytime there is something in the air that you don’t want to breathe in,” but here are some specific suggestions:

• When you are around allergens that affect you like pollen, grass, or pets
• In cities or environments with a lot of air pollution
• Work environments where there is a lot of dust or debris in the air such as construction sites, warehouses, or factories
• Traveling on an airplane, bus, or any other crowded space where you want to protect yourself from other people’s germs
• When you are using cleaning products
• At the dentist so you don’t breathe in debris that the drills and lasers are aerosolizing
• Visiting a hospital or other places where there are sick people
• When shooting at a gun range to protect yourself from breathing in the lead dust in the air

O2 Nose Filters are practically invisible as they go inside your nostrils, whereas nasal strips attach like a piece of tape across the top of your nose. The adhesive used in nasal strips can cause skin irritation, allergic reactions, or blemishes, and they do not provide any filtration protection.

There is a widespread misconception that surgical masks protect the wearer from whatever is in the air around them, but they are primarily designed to protect others from the person wearing the mask. For example: if a doctor coughs while performing surgery, his mask primarily protects the patient from infection. An excerpt from 3M states:

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

Many procedures performed by the dental team have the potential to create aerosols containing microbes from the oral cavity. Aerosols are tiny particles or droplets, which can float in the air for considerable time and be inhaled by dental staff and patients. These aerosols are contaminated with microorganisms and blood and thus represent an infection hazard. A 400% increase of airborne bacteria has been observed in areas where aerosol-producing equipment was used.

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 materials 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.

In many work environments, employers are required to provide workers with breathing protection. Wearing disposable face masks tend to inhibit communication, get hot, humid, and uncomfortable, and restrict airflow. All too often that means there is a low compliance rate, which leaves workers unprotected for dust, chemicals, and other airborne pollutants.

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.
