Post filter replacement/water quality

The filter replacement is going much smoother than at first. It’s easier to to detach. As always the water quality and taste is outstanding.

Delay shipment

Excellent customer service! Barbara is always extremely helpful!!

We really love having clean drinking water. The taste is wonderful but the water is purified and that is important to us.
