I've been using this type of filter for a few years now and I have to say it's a lot! You will get a filter attachment along with 3 ceramic filters each of which will last around 3-4 months as it really depends on usage. all for $23! Annual cost of pure filtered water at $23. pretty good. And since I've been using this type of filter for a few years now, I honestly haven't had any trouble installing it and the quality is as good as any other filter of a similar design.
