Product review (5 stars): Filters that work!
My giant humidifier saves my skin and breathing every single winter. These filters are the only thing I have to change other then add water and they are perfect. In the past I have had to piece together several other filters to make one large enough to fit and they never were as good. So happy to find these on Amazon. The price is as good as it gets as well. Will buy again and again!  Thanks Holmes and Amazon!
