1, How long dose the nasal filter lasts?
The frame can be continuously used for long-term with proper care. Wash WoodyKnows nasal frame every
day with 70% alcohol and dry it in the shade is highly recommend. The material is softer for user comfort, so
please pull it carefully. The removable filters should be replaced 2-3 days. Washing the disposable filter
replacements is not recommended, as this may reduce the filter efficacy.
2, How to select the sizes?
Please refer to the product description "Round Vs. Slotted Nostril" to decide if you need round or slotted sizes.
Please refer to the Size Specification (Unit: mm) to know the specifications of all the sizes. First-time buyers are
recommended to order the multipack-(IR/IIR/IIIR/IVR) or multipack-(IS/IIS/IIIS/IVS). Everyone nose is shaped
differently, and mixed size pack is a more efficient tool than measuring size by customers.
3, Which nasal filter is suitable for me?
Different nasal filter has different features, please refer to the nasal filter description for more details and select
the most suitable for you.
4, How do I know the which sizes is fit for me?
The filter should be a little bit bigger than your nasal passage for a better seal. The filter is expected to open your
passage a little bit widely but not uncomfortably. It may take one day for new users to adapt to it. If you feel the
nasal passage is opened very widely and uncomfortably, it is too big to fit.
