Product review (5 stars): Works in multiple vaporizers
Nice filters, fit in my Vicks cool mist vaporizer as well as my store brand filter.  I rinse them about once a day to get any residue off of them, and they last at least a month.  I use the cartridges that drop into the water tank to extend the life of the filters, and I have noticed a big difference in the condition and life of the filters when used with the cartridges.
