Product review (4 stars): Would also recommend running a pitcher of water thru the filter after ...
Installed filter after having OEM filter in maybe a year and noticed the increased water pressure from the new filter which is higher than if a OEM filter was installed. Mainly use filtered water for filling coffee pot and little else.  I don't know how this increase in water pressure affects filtration since I equate having more pressure with less restriction therefore, less filtration. Would also recommend running a pitcher of water thru the filter after installation and before using, I noticed some sediment and slime looking particles in the water, but after running water thru the filter it soon cleared up. Will check for leaks over the next several days and update post. 10/19/16 Update, did some research and found the floating film was from bacteria growing in the line after the filter.  Since most filters remove chlorine, bacteria tends to grow in the supply line going to the water dispenser at the door, located after the filter. I am assuming the increased  pressure resulted in the bacteria lining the tubing to be dislodged. It raised concern since, several days later the film like slime was still coming out.  The only remedy seems to replace the coil tubing from the door to the filter.  Also changed rating to 4 stars
