We recently came across this water filter comparison chart-Click Here
Sort of crazy that the pitcher water filter and point of use attached to the faucet spout water filters seemed to fair so poorly in the report
We have been quite happy with our Point of Use Under the Sink Unit that is offered on Conservastore.com
This housing can be purchased in clear or blue and comes with a replaceable Carbon Block cartridge that will last you up to 6000 gallons.
If you have some of your favorite stainless water containers and refill them each morning before work you will not need to buy bottled water which is quite expensive and may be filtered no better than what this system will do
Thanks so much
