INNOVATIVE PROTECTION | O2 Nose Filters are a nasal dilator paired with advanced 3M filtration technology to improve airflow while helping prevent airborne particles such as pollen, pet dander, mold spores, pollution, bacteria, viruses, and dust from entering your nasal passages.

CLEANER AIR, WHEREVER YOU GO | Multiple layers of electrostatic material capture up to 90% of harmful airborne particles at PM10 and 65% at PM2.5. Ideal for everyday use in cities, hospitals and medical facilities, public transportation – anywhere there is something in the air you don’t want to breathe in!

FIND THE SIZE THAT’S RIGHT FOR YOU | Noses come in many sizes, and so do our filters! Our Sizing Pack, containing 1 filter of Small, Medium, Large, and Extra-Large, is a great and economical way to explore your options. Once you have determined the right size for you, the lightweight and discreet filter will contour to the inside of your nose. Larger sizes may provide increased airflow, while smaller may maximize extended wearing comfort.

COMFORTABLE & DISCREET | Made from soft, medical-grade Thermoplastic Elastomer (TPE), O2 Nose Filters adapt to fit most noses and are comfortable to wear for long periods of time. The clear matte finish makes them nearly invisible for all skin tones. Our filters are discreet and don’t inhibit conversation, so they are great for everyday use in the workplace, industrial areas, public transportation, and outdoors.

EASY TO WEAR | Simply place in the nose with the connecting band down to enjoy cleaner air and easier breathing for up to 12 hours. After a full day of use, or when the filter material is visibly dirty, please recycle with other soft plastics.

    First time user and love it. Great for blocking pollen, exhaust, and other radicals when outside. Large size is a true fit for me. Be mindful nostril size. 😉

    The nose filter works. It cleared my nasal passage and stopped the clogging sensation I was getting at the esophagus.

    So I was sitting at home, lamenting the fact that the cottonwoods/poplars and pollen, and warehouse dust just kill me every day and make me feel miserable. And I was thinking, you know, it would be great if I could just shrink down a filter and have it sit in my nose. I checked Amazon, and sure enough, there it was. I ordered it, and tried them out that very next day. I have included a photograph of what the filter looks like before my workday, and after my workday which includes working in a warehouse, walking through wooded pathways with poplar/cottonwood flying around, under pine trees with pollen, and sitting next to some fresh cut grass. ALL of those things used to cause me misery. I am definitely happy with this product. It feels so weird to have your nose feeling a filter for hours on end, but I am able to calm the anxiety of that, but reminding myself that I at least KNOW what is in my nose. A filter, no boogers or weird pieces of whatever is floating in the air. Definitely loving this, and will be ordering tons more. It’s worth the money (kinda) for me to get to breathe easily and not freak out about inhaling crap all day long. I got both the medium and the large sizes, since some days i get some nasal inflammation that causes me to need the mediums. uploaded another image with measurements and packaging

    Occassionally need adjusted. Comfortable to wear.

    Make sure you choose correct size. These fit well and are a great defense against allergies and coupled with a mask right now is worth your health. I wear these to work and when mowing or on high pollen days.

    This filter worked well. I bought a size too big (large vs medium) as it wasnt in stock during the time of purchase and it led to some discomfort but the pros outweigh the cons. It reduced my runny noses from seasonal allergies I’d say by a half. It also gave me a peace of mind as its flu season and my classmates are always coughing. This also helps avoid the stigma against wearing face masks out in public.

    “I work in construction so there’s dust everywhere all the time and my allergies kill me during the night because of all the exposure during the day so that’s why I bought this little guys, also because masks are uncomfortable to wear all day.
    They’re quite easy to put on once you get your right size and they stay on all day. I work 10 hour days and they stay on all day. I dont sneeze at all and feel so much better now that I use them. I would highly recommend them if your able enough to figure how to put them on, they’re very comfortable too and I can barely tell I have them on. I’m pretty sure most of the bad reviews are because they dont know how to put them on, which quite easy once you get the hang of it. They’re one time use which sucks but they’re worth the money.”

    Excellent prevents sawdust and debris coming up ur nose

  9. Laura

    I really like these filters, they fit fine.
    Great Idea! They fit inside the nose not taped on the nostril.
    I just need to courage to start wearing them.

  10. Brandia

    I ordered the wrong size this time but when you order the right size they are a lifesaver.

  11. AC

    The best product I have seen and used for sinus trouble. Keeps your nasal passages open and filters out a lot of things that make you sneeze. Easy to put in and take out. A good quality product with a great design. After testing several of these products, I regard this one as the best of the lot. It works, it lasts, and I easily sleep while wearing it.

  12. Customer

    I started using them for international travel and decided to use them whenever traveling. Just bought another box. I have worn them even at work as as to date no one has ever seen or questioned.

    These are SO much better than a face mask! The edges have a sort of ribbing that make them stay in my nose (and I expect mostly anyone else’s nose). I gave a set to a lady with severe allergies before we went outside with a group doing a nature walk, and she was amazed they kept her nose from running. It is far less noticeable than a face mask.
