Product review (2 stars): Save your money and don't by these filters
I had several of these filters and one of them didn't even last a week.  What happens is that after the water has wicked up in them the absorbent material breaks all the way around about an inch up so that water can no longer wick its way to the top.  save your money and look for a good equivalent filter online. I found mine at filtersfast.com the honeywell filters seem to have a manufacturing issue at least in my professional opinion.  On the positive side, I did call Kaz who manufactures these filters and they sent me a replacement for my trouble so if you heed my warning and purchase them anyway do call and complain if you have an issue.
