Product review (5 stars): Using to filter all my cold water
I was looking for a quick change filter for both my cold water faucet (when cooking) and the water to my refrigerator.  I first looked at the Culligan US-EZ-1 and almost purchased it before I found this.  This is much cheaper since I didn't want an additional faucet.  I was able to connect it directly to my cold water faucet using some parts from Home Depot.  It does however reduce the flow to the cold water faucet which Culligan warned me about.  My other option was the 3M Filterete 3US-PS01 which has larger tubing and would likely not reduce the flow to the cold water faucet.  Unfortunately the 3M filters don't last as long and cost more.  I will be keeping the Culligan at least until the wife tells me otherwise.  I would have preferred them to have used larger diameter tubing so that flow would not have been an issue for the cold water faucet but I'm giving it 5 stars since it works great for its intended purpose (water to my refrigerator).
