Product review (5 stars): Holmes Humidifier Filter - HWF62
The quality is very good, it came with a very secure box to protect the shape of the filter.  Each filter can last for 3 months if you maintain in good cleaning. I usually ordered this kind of filter in a cheaper price at other store, but I found out that its quality was not as good as "Homes".  I am very satisfied with this purchase and will buy it again when I need it.
