Physical Protection from Allergy: WoodyKnows Nasal Filter is a physical way to block inhaled allergens. A good alternative to nasal spray and a good combination with it to achieve the best anti-allergy results.
Instant Allergy Relief : Advanced electrostatic filters are very effective in keeping allergens(pollen, dust, dander & mold, pet hair, PM 2.5 etc.) from getting into your nose. Protect you against nasal allergies, sinusitis, and rhinitis.
Ergonomic & Comfortable: The filter frame is designed according to your nostrils’ natural shape, Round or Slotted, for the best comfort, fit and seal.
Soft & Safe Material: The frame is made from very soft plastic, Latex-free, BPA and Phthalate-free. It will deform according to your nasal passage to fit you the best.
Invisible & Economic: The nasal filter is put in your nose and the black retainer rings do a great job of hiding the white filters. Reusable and very easy to rinse. You can wash it with soap water or 70% alcohol every day and dry it in shade.

There are two shapes of nasal filters for your choice, round shape and slotted shape. Please choose it according to the shape of your nostrils. The size of nasal cavity is different from size of nose. First-time buyers are highly recommended to order the multi-size.
Remove a pair of filters from the silver plastic bag. One side of the filter is net and the other side is fiber. Install a pair of replacement filter into each frame with its net side facing you. Then install the black retainer ring into each frame. The filter and black retainer ring should now be secured by the frame tabs.
