The water looks clear and has no odor but I have not had it tested so I assume it is okay. The price was fine, installation was quite simple and almost anyone could do it. The only downside is the volume of water coming through the filters. Don't expect anything close to the flow from your faucet. It takes a full 3 minutes to fill a small 6 cup coffee pot. Not a deal breaker but it is an issue.

2 Stage Filter
I bought this to replace a 2 stage filter from Lowes. The new filters were so restrictive that it allowed only a trickle through. I tried two single stage filters but they did not improve the water taste sufficiently. I bought this model with the thought I could use other more restrictive filters, if the taste and quality was not good. But I found it and the accompanying filters to be great. Wonderful taste and volume. Excellant quality and easy to install.

Questions & Answers

Q: Does this filter reduce TDS? I recently bought a unit and tested for Total Dissolved Solids. I was surprised to see a slight increase. Is this normal?
Asked by:  - 8/27/2014 (Submit an answer)
A: With the filters it comes with, no. You need to get a mixed bed DI filter if you want to lower TDS. Don't be surprised when you see an increase in TDS. Carbon filters do not necessarily always remove contaminants but at times reacts and converts contaminants into a different form less harmful. An example is Chlorine, when Chlorine reacts with carbon it converts to a chloride ion instead hence two ions of chloride for every Chlorine molecule. TDS doesn't mean anything if you don't know what the number represents so take that number with a grain of salt.
