Query: Fits my Watts Filter and Ahhhh, Clean Water.....

I have had my Watts Water filter that I bought here at Amazon for 4 years or more now. Even though it's just me using it, I still change the filter about every year, The original filter I took out didn't look that bad after the first year, but that's when I replaced it with one of these KX filters. After a year or so with that one, the water flow out if the filter dropped quite a bit. That showed just how much it had worked for me.These filters deliver "Spring water" quality, no matter how bad the city water is. All you have to do is get one of these and a cheapo Automobile Oil Filter changer tool ($6.00) to swap it out. Just be sure to clean out the filters insides as well when you open in. Also, let it run for a good 5 to 10 minutes before you test the "New" water. I tried the water too soon and it tasted a little oily.
