I happen to know from snooping that my loving wife is giving me a nice size AG gift certificate for Xmas. I have been looking at the Clear Inline Hose Filter for some time now but have not wanted to spend the $$. Now that I will have "found money" and considering the 20% off till 12/26, I was thinking of getting this little toy. Anyone have comments on how well it works and how it works with a foam gun (that is, does it reduce the water pressure too much?). I do have a hard water problem here in the Phila., Pa. area. Thanks much and a very very happy and healthy holiday season to all my new found geek friends.
