Title: Smelly carbon block filter
Review: This filter unit install easily under the sink but came with the wrong second filter (sediment). Once I received the correct carbon block filter the water began to have a very sour taste and odor. Crystal Quest recommended a particular flushing method that involves two sessions 24 hours apart but this failed to correct the foul odor. It's difficult to understand how a carbon filter can cause such a bad taste to water. I will be returning it for a refund, moving on to a different company's under sink filter.Two stars because of the helpfulness of the Crystal Quest support people. Hopefully the company will get a handle on this problem in the near future.
