Hello All, I'm hoping some of you will help me with my latest dilemna. I am looking to buy a whole house water filter. I saw a few I'm considering, ranging from about 800 to 2000 bucks. I'm trying to find some kind of review on them but find nothing. The best I can find are reviews for the kind that you screw on your kitchen tap. Doen anyone use such a device in their home and if so, can you advise me as to what to look for and what to avoid? Specific brand recommendations are also welcome. Thanks.
