Rated 5 out of 5 by from Clear Water Purchased this Filtrete whole house water filter after reading many reviews on it and other brands. So far filter is preforming as advertised. Instructions were easy to follow and installation was not hard. Do not be in a hurry and have all parts for installation on hand. Filter housing clicked into place with a twist and I had no leaks when water was turned on. Be sure to put plenty of silicon on areas indicated in instructions. Some reviewers had a loss of water pressure which was a concern, but I did not have any loss of water pressure. Do not know if filter will last for one year, as I have only had it for a month, but will find out. Price, quality. ease of installation and filtration is why I would recommend this Filtrete water filter.

Rated 1 out of 5 by from Very disapointed in the system I bought the system not knowing that it could only be installed in a water system that only ran in one direction. There is no mention of this on the expensive package or in the directions. After purchasing the p[arts and doing all the plumbing I noticed that it had a water flow direction on the product, and was told that I could use it that way, but would not get as long of use out of an expensive filter. I think they should at least offer warn about this requirement before that sale of the product.
