Product review (1 stars): Sometimes these filters just don't work.  Not sure why.
Screwed right in. Didn't work.  No water flowed into  it. Looked it over and didn't see what was causing the problem, nothing looked questionable.  Checked the model number, it was the right one. Tried a dozen times, still didn't work.  Got a refund in no time.  Ordered a replacement from another company,  just in case.  This happened once before with a genuine GE filter.
