USING O2 NOSE FILTERS

How do you wear the O2 Nose Filters?

1. With clean hands remove the filter from the travel case.

2. 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.

3. 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 are the O2 Nose Filters Made Of?

The 3M Filtration media is set in a soft, latex-free rubber form.

What size am I?

Noses come in many shapes and sizes – so do our filters!

 

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?

Our O2 Nose Filters are designed for up to 12 hours of use, however in dusty or especially polluted environments, you may need to change it more often. It is important to use the right size and for optimal comfort and protection, so make sure there are no gaps between the inside of your nostrils and the filters. 

Can I use my O2 filters more than once?

The O2 Nose Filters are designed for one-time use up to 12 hours. We do not recommend re-using a filter.

O2 filters protect my nose but what about my mouth?

The good news is that the acids in saliva effectively neutralize most of the bad stuff that gets into your mouth. Your warm, moist nasal and sinus cavities are the most important place to protect as this is where germs, viruses and bacteria tend to lodge and multiply. So, once you have your O2 filters in place try to breathe through your nose as much as possible to take advantage of the protection the O2 filters provide.

Do O2 Nose Filters prevent snoring?

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

Are the O2 Nose Filters Drug Free?

Our O2 Nose Filters are not made with any drugs or medicine in them.

We recommend they be worn as a preventative measure against the symptoms of airborne allergens and pollutants.

Where can I buy O2 Nose Filters?

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

Bulk packaging for professional and industrial use is also available. If you are interested please email us at hello@o2nosefilters.com

Why should I wear O2 Nose Filters?

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 spores

Where should I use O2 Nose Filters?

The easy answer is “anywhere there is something in the air that you don’t want to breath into your sinus cavities and lungs” . . . but here are some specific suggestions:

  • 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?

O2 Nose Filters are practically invisible as they go inside your nostril, whereas nasal strips look like a strip of tape across the top of your nose. Nasal strips are applied with an adhesive, which can cause skin irritation and allergic reactions, and they do not provide any filtration protection.

Why is O2 better protection than wearing a surgical mask?

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 – Read this excerpt from 3M.

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?

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 before being 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 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?

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.

ABOUT O2 TECHNOLOGY

What size particles will the O2 filters protect me from?

The filtration efficiency of the 3M material varies based on the size and speed of the particles – testing of the O2 Nose Filters demonstrate better than 70% efficiency at 2.5 microns and over 90% at 10 microns.

  • 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%.

* The above tests were conducted at LMS Technologies, an independent 3rd party testing lab.

What size particles are considered to be hazardous for humans?

• Inhalable Dust: Airborne particles which can enter the nose and mouth during normal breathing. Particles of 100 microns diameter or less.

• 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?

All airborne contaminates can be expected to, depending on the atmospheric conditions, take on some water vapor. This is called the “Condensation Effect.” The higher the humidity the more significant it becomes until contaminates trapped in the water, now a fog, mist or larger droplets, fall to the earth.

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.
