The Pentair QL3B water filter system is installed under the counter and includes an Everpure S-100 replacement filter with a filtration rating of 0.5 μm. Micro-Pure Filtration technology reduces chlorine, odors, and cloudiness, while removing cysts such as Cryptosporidium and Giardia, asbestos fibers, and algae. It also reduces iron and manganese oxides and sulfates.

The filter has a sealed interior and a metal housing, while the check valve prevents water from dripping. It can be replaced without a wrench with a half-turn and fits Everpure QL3B, QL3, QL2B, and QL2 heads. It is certified to NSF/ANSI 42 and NSF/ANSI 53.
