Read other reviews and there were notes about dark water right after installation. Those notes are true. It is recommended to run a couple of gallons of water to flush the filter and clear out the air in the line. So far, no problems with the water. It fits an Whirlpool 26 cu ft French door frig with no problems. Same size as the OEM filter that I removed.
