Product review (5 stars): Works great, costs less
I tried this filter off of the other reviews and what they said is true. It works great and it costs less. Plus, this filter has some antimicrobial something in it that the other more expensive ones don't, it has some silver liner built into the middle of it. I have noticed that I haven't had to use that liquid bacteria killer with this filter (so far anyway, after 1 month of use).
