Rated 5 out of 5 by from These filters work well. These pre-filters change easily and filter out a lot of crud. Easiest part of the system. (Although I would order my entire system locally next time, the customer service has been decent.) The maintenance of changing the pre/post filters is quite easy.

Rated 3 out of 5 by from Yup, it's a filter. They sent me what I ordered. Maybe they could make it a little easier to determine what replacement filters go with what system and when/ how often they should be changed. Why is it left to the consumer to dig around through the PDF publications on the site for this info? After committing the kind of money we have to these filters I don't think it's too much to expect. Also, include the lubricant for the "O" ring with the filter!

Rated 5 out of 5 by from Great value. Delicious water. We turned off the Aquasana when we installed the new one. I had a drink upstairs before switching the new one on. I couldn't believe the difference. Like locking a flagpole. Don't think I'll be switching the new one off ever... Delicious water.
