Undersink filtering - Where to start?

[Traceyjean]

We are trying to figure out the best undersink filtering option for us. We have a well water supply and having been having issues with sediment in the water - turns it a bit cloudy. We have whole house filters already - one is a huge canister type not sure how it works - some type of sand perhaps? Then we have a 10" carbon filter which we purchased from you.

The reason we have come to the conclusion that we want to do additional filtering is that the water that comes from our fridge's drinking water line (using an Aqua Pure filter) is crystal clear. So obviously that is filtering better that our current system. However, I do not want to only have a little drinking faucet, I would like to have the main cold water at the faucet be well filtered as well - for cooking mainly in addition to filling up pitchers of water at a time.

Once you start looking at 10 micron vs 5 vs .5 micron filters you start to think - if I am going to do this I want to do the best filtering possible. Especially since we have well water and can't necessarily anticipate what contaminants might be in there? Any help to point us in the right direction would be greatly appreciated.

Whole house filtering can do a good job with particle and chlorine filtration. It cannot get to the level of filtration that an undersink filter gets because this quality of filtration slows down the flow rate too much.

To get the best quality undersink filtration, you need reverse osmosis. Here are your options.
Reverse Osmosis Systems and RO Water Filters for RO Systems
The PT-3500 is the most popular system we have.

Jamin -

Can you help me to understand what is feasible? We were initially looking at purchasing a Clear2O pitcher since it seems to have remarkable stats as far as the water's quality after filtering. But we heard reviews of it being awkward to use again and again. Then we went to putting some type of whole house filter under the sink. Using something like the Culligan US-600 housing with a CBR2-10 filter inside. But after reading and reading and reading - I started to question if that would work. If we went with a RO system (which I am not keen on because of it size and waste of water) do we only get high quality water from a little drinking faucet or is there an option that would go to the main faucet? Or both? Please help with some more advice. Thanks!

The best filtration comes from Reverse Osmosis systems. RO systems reduce dissolved solids in the water such as nitrates, nitrites, barium, etc. The RO membrane is the part of the RO system that reduces dissolved solids. Regular filters cannot reduce dissolved solids. Here is a easy to use RO system:

You can use the Culligan US-600 and hook it up to your main faucet. However, if you have it connected to your main faucet, you will want to use the D-20 filter. If you use the CBR2-10 filter, the flow rate will be very slow because the CBR2-10 reduces more contaminants. For any high contaminant reduction filter, you will need a separate drinking water faucet because the filter requires more contact time thus slower flow rate.

Another under sink option that isn't an RO system but comes with a separate drinking water faucet and a really good filter for contaminant reduction is the Culligan US-EZ-4:
