Testing helps Wenger determine which category fits the concern and whether more than one treatment stage is appropriate.
Water Filter: A water filter uses media selected for a specific condition, such as sediment, taste, odor, chlorine, iron, sulfur, or another tested concern. The term “filter” does not describe one universal system.
Water Softener: A conventional softener addresses hardness minerals associated with scale, spotting, and mineral buildup. It requires salt or potassium, regeneration, and periodic service.
Water Conditioner: A conditioner may use a different treatment method intended to manage scale without removing hardness in the same way as a conventional softener. System capabilities and limitations should be explained before selection.
Reverse Osmosis: Reverse osmosis is generally used at a selected drinking-water tap. It has specific filter, membrane, pretreatment, space, water-use, and maintenance requirements.
