Product review (1 stars): A lot of Carbon!
The Refresh filter had A LOT of carbon that needed to be flushed out, several more gallons more were needed then other filters I've had in the past.  In addition, it seems to move more water (higher water pressure ~glass fills up faster) than other USA made filters, which usually means it's not filtering as much (which usually slows the water down).  It's only been ~5 days since I installed it, in a house of four people, but it seems like it's still putting out a little black (carbon maybe) chip every once and a while.  For the price, not exactly comforting health and safety wise....and I'm not a health nut..just trying to make sure my family has health water.
