Product review (5 stars): Necessary and reasonably priced
If you have the Remedies Cool Mist humidifier you need the filters to replace the original.  Since we love the humidifier, we need the filters.  They are easy to use and easy to replace.  We haven't seen anything growing in the humidifier, so it seems as if these filters do the job.  Not a bad price for 3.  Compared to other units with filters like Vornado, these are a great price per filter.
