  • NOSA allergy filter contains a filter media that filters out particles in the size range of PM10 and larger, reducing the amount of allergen particles that enter the nose. The sealing design (sealing skirt) forces the airflow to pass through the filter media inside the device. It is important that the sealing skirt seals tight against the inside of your nose, so that no allergens get past the filter media. 

Allergic reactions is due to an inflammation of the nasal membranes (allergic rhinitis) and can be recognized by sneezing, nasal congestion, nasal itching, and rhinorrhea.¹

Since a lot of the allergic symptoms are due to an inflammation of the nasal membranes, your main focus should be to protect your nose. Preferably, breathe through your nose while using nasal filters to reduce the amount of allergens that reach your respiratory system.

Allergic Rhinitis is an inflammation of the nasal membranes and can be recognized by sneezing, nasal congestion, nasal itching, and rhinorrhea.¹

One good way to prevent allergic rhinitis is to avoid the allergens that cause the allergic reaction as much as possible. However, this is easier said than done. Allergens from pollen, dust and pet dander could be present in the air and on surfaces that we are exposed to every day.

See the descriptive image below. 
NOSA filter consists of a “filter house” and a “sealing skirt”. The filter house should fill your whole nostrils. The function of the sealing skirt is to seal and make sure no air leaks through on the edges.
Match your nostrils to the size of the filter house.

If you are unsure of which size you should choose, try our filter kit!
