Thank you for contacting Biobidet Support.
The deodorizer filter will last a very long time. The filter is intended to last the lifetime of any bidet. If for any reason though you notice an unusual smell or unpleasant smell from this filter, they are also available for purchase at biobidet.com under "accessories".
