I've posted before on my cheap, easy to install, and convenient GE filter installed on my cold water line under my cleanup sink. I'm very happy with it. I did an Internet search for all my posts on threads like this and will link to the search at the bottom of the page. You'll find lots of posts there! If you're looking for a more complicated system, I'm sure someone else will chime in with their advice. Good luck!

Thanks for the reply ang the link.

I almost decided to go with GE PNRQ15RB since it is sold in local store homedepot ( 20RB and 21RB are not sold there, they won't do special order either). I went to a homedepot, but it looks like a lot of boxes of this product are customer returned. I feel the product looks like a bit cheap, made me doubt about it.

Are you happy with your GE? Is it RO system? What's model #?

I had/have a reverse osmosis system. Apparently, it does have the best results for filtering water. However, it takes up a lot of space under the cabinet. It has 3 filters and a holding tank. Thankfully, with my just about to be done new kitchen (yay!), the plumber moved all the filters down to the basement and ran the plumbing up. I am not sure how convenient that's going to be for changing and cleaning everything. But, at least I have my sink cabinet back.

Yes. I have thought about having RO system. However, my worries are: (1) warer waste (2) what if leaking, our kitchen has hardwood floor (3) how long it can last.
I am thinking to get 3M body glove now. The important reason is I don't find bad comments about it.:) They all meet NSF standard.

Have you looked at MultiPure Aquaversa? It gets good reviews on Consumer Reports and isn't crazy expensive. I saw it for $375 on Amazon. I think that is what we are going with after looking at a ton of options. I like the idea of the RO but the expense and water waste keep me from trying it. I wish there was a local store where you could try out these filtration products on the tap water.

We also moved the RO system to the basement and it was so nice to regain the space.

I'll link the one I have below. It's very basic, inexpesive, easy to install, and the water from it tastes wonderfully clean and delicious. I didn't really understand filters so I asked a nice sales associate at the orange box store who guided me to this GE unit. I'm surprised at how great it is, especially for the price. I'm very happy!

The filters say they last six months, but the original filter that came with my unit is still on a year later and doing well.

MultiPure Aquaversa seems ver nice, but I didn't check the responses early.

It depends on what you are worried about and concerned about what is in your water. Also, about what you know is there. After the research I had done, I recently got a reverse osmosis system, and yes, as stated above, takes up a lot of space under the sink, and does waste water, but the water wasted is contaminated, while regular water filters such as the ones suggested above allow most chemicals through. Reverse osmosis is the best available technology for purifying your water. I got my RO system from Aquasafe Systems, and read some reviews where people have had their systems for over 10 years before replacing. That's the unit itself, not the filters as they need to be replaced every 6 months, but the water quality is unsurpassed. Click here to check out their site. They also have some interesting blogs about what is in your water.

And to mononoke1, you should never rush into buying a water filter without researching first. A lot of companies out there use a play on words, such as "effective against" or "reduces" but don't post stats or facts, when both terms could potentially mean very little protection.
