This factory original refrigerator water filter is meant to replace filters on the LG and Kenmore refrigerators. If you are looking to remove cysts from your water, then you will want the "B" model of this filter, because the "A" model is not designed to remove them. While this filter fits refrigerators with water dispensers on the outside of the fridge door, it will not fit those with the dispensers on the inside of the door.
The pressure rating with this filter can vary between 30 and 120 pounds per square inch, and the filter has a capacity of 300 gallons. It should last between three and six months, depending on how much it is used. Flow rate is about half a gallon per minute and operates at 33 to 100 degrees. Replacing the filter is easy: all you need to do is take hold of the old filter, give it about a quarter turn counterclockwise and slide out. Put the new filter in until it stops, and then turn clockwise until it stops turning. Flush about three gallons out and it is ready to use. No tools needed! Sold in an economical three-pack, you only need to buy filters about once per year.
