I put the Pura Ultraviolet system in about two years ago after reading about it on this site. It has a sediment filter, a carbon block filter, and a UV chamber. I left the small Lowe's filter that had been my prior filter in place before the Pura system. The thought was that the $5 filters that I could change every couple of weeks might keep the majority of the sediment from reaching the Pura system and allow it to function better. It has been excellent.
Two week after I installed it I took a sample to the Laconia Water Department for testing and they said it was drinking quality water. So, after all these years I was able to put an ice maker in my freezer. (priorities!)
I think the cost of testing in Laconia was about $20 but they may require you to be a Laconia property owner.
