Good job

These filters really do a good job of taking the smell and heavy metals out of the water. The clear filter definitely is working as the color changes over the 6 months it is in service. You can see how much ‘stuff' is filtered out. The only issue is in changing the filters as they are a bit heavy to remove as they are full of water. That would be the case with any water filtration system. It requires focus and strength, but very doable by most people. Don't pay a company to do it.

Difficult to switch filters

While I am quite independent, at 67 I find switching the filters very cumbersome - difficult really. There should be some way to drain the water from the containers from the bottom.

We anticipate great results

We have not installed the replacement filters, we ordered early to have on hand. We expect the same quality as our current filters.
