Product review (1 stars): Terrible filter, not worth the money.  Go with generic instead for a better product.
Terrible water filter.  Not like the old PUR filters.  When I initially installed this, it made a loud hammering noise, I immediately removed it and re-inserted it.  That seemed to fix the noise, and the water came through fine.  Was a little slower then previously but seemed ok. However after one month the load noise came back.  Sounded like the pump was dry and hammering the air\water.  The filter was not worth the cost, and had to replace this way to soon for the price.  Ended up picking up a HDX set from Home Depot for 1/2 the cost and it seems to be fine.
