On my 3rd filter.
This is my 3rd filter and I have to say the taste and quality of the filtration is incredible for the money. And it continues to perform as advertised up to 1 year. Installation of the replacement is not the easiest, but for a counter-top 10-stage filter that only needs to be replaced once a year, it's a minor inconvenience that I'm more than willing to go through.
