Product review (3 stars): Chinese made filter
This product appears to be well made.  However, I have no way of determining how well it really filters the water.  I have given the product 3 stars because although they are designed in the US, they are made in China and there have been quality control issues in the past with Chinese made products not being what they are supposed to be.  Don't know if the US company that designs these filters routinely checks them to see if they are actually filtering properly and not adding anything they shouldn't.  You will pay more for a US made filter, but if Chinese made products are a concern to you buying a US made filter may be a better way to go.
