In our water, it seemed that the water when boiled on stove was clear and now we are getting a little whitish color on sides of pan again. Nothing like before the unit was installed though. I was wondering if this is still possibly sediment coming from pipes, or faucet? Or is it possible it may never be totally clear when we boil water due to the hardness? I assume, regardless, it shouldn’t hurt us since it should still be filtered out of us when we drink it?

This condition is probably a combination of both and yes it will just pass through you.
