Question: how much is the replacement filter and when is replacement recommended?
Document: did not meet our needs good enough. i am sure it is a good unit, just not what we needed.
Works well, I  just wish that it had a setting for what pH you wanted, rather than &#34;coffee&#34;, &#34;cooking&#34; etc.
I recently got this up and going, and it's easy to use. The only thing I don't like is that I don't know what the actual pH reading is. I have to test the water and match it to the color chart, so it's probably not very accurate. I guess you get what you pay for, but so far I am happy with it and the price is right.
I purchased the product more than a month ago, till now I cannot make it works with existing home faucets connection. Don't know if I have to hire a professional to do it?? Now I am not able even return it because it was ordered over 30days (never use it), so it is now  sitting in my storage. I cannot rate the quality of this product, but it is definite difficult to install it!
