Product review (1 stars): Avoid- Buy the OEM Holmes Example.
This filter is one week old and it will not permeate water all the way to the top of the wick. I.e. it's useless after one week, used with bacteriostatic water treatment. Plus, it's not that much cheaper than the Holmes OEM one. The only reason I ordered this one was because Amazon had the Holmes one stocked incorrectly and I kept getting the wrong filter.
