Filtration Process

Sediment filtration
goh2o states the sediment filter is the first stage and catches dirt, rust, and other solid particles.
Carbon filtration

Water is forced at high pressure through a semi-permeable membrane. The rejected water is flushed away.
Post carbon filtration
goh2o describes this stage as a final polish for taste and odor.
Alkaline filter
goh2o states this filter adds minerals such as potassium, magnesium, and calcium, which raise the pH.
Ultraviolet sterilization
