Product review (5 stars): Works good
Just an FYI these HDX FILTERS. Thread on in 2 positions. There's no way to tell. I think on position in the 180* allows the water to flow threw in the WRONG direction. Just pop it off and turn it 180* and reinstall and no more charcoal coming out. They do work fine but don't filter as well as the OEM filters that cost 50$ each!!
