WSP 1/3 cu. ft. Filter Media - Kdf- Process

Water Softener Plus (WSP) 1/3 cu. ft. Filter Media is the core filtration material inside your water treatment tank. Made with KDF-85 copper-zinc alloy granules and activated carbon, it reduces chlorine, heavy metals, and inhibits bacterial growth to keep your water cleaner and your system working well.

What Stands Out When a Plumber Looks at Your Water Filtration Setup?

When a plumber inspects your water filtration system, one of the first things they notice is the condition and type of media inside the tank. This media is what actually treats your water by filtering out unwanted substances. If that media is old or the wrong kind, your water may still taste or smell off, or contaminants like chlorine and heavy metals might slip through.

Understanding the media inside your tank explains a lot about what your system can do and how well it will last before needing replacement or maintenance.

How the Control Head Manages Filtration Cycles

The control head on your water treatment tank directs the flow of water through the media and decides when to backwash or regenerate the system. While this filter media itself does not regenerate, the control head ensures water passes evenly through the media bed for consistent treatment. Settings you or your plumber choose help save water and extend the media’s effectiveness by managing the timing of these processes.

What This Filter Media Does for Your Water

This filter media combines KDF-85 copper-zinc alloy granules and granular activated carbon. The KDF-85 works by a redox (reduction-oxidation) process that targets chlorine and heavy metals like lead and mercury, while also suppressing bacterial growth within the media bed. The activated carbon focuses on improving taste and reducing odors caused by chlorine. Together, these materials reduce sediment buildup inside the tank, helping downstream filters and components last longer.

Tank Size and Media Volume Explained

The media is designed to fit a standard 13-inch by 54-inch tank, holding about three cubic feet of filter material. This volume supports strong filtration performance suitable for typical residential water systems. The tank size allows sufficient contact time between water and the media, which is important to reduce chlorine and heavy metals effectively.

Who Should Choose This Media Volume?

This 1/3 cubic foot media volume suits homes with regular water usage and typical household water quality concerns, especially where chlorine and heavy metals are noticeable. If your home has unusually high water usage, or your water test shows very high contaminant levels, you might need a larger media volume or a different filtration setup. Conversely, smaller homes or systems with low flow may do well with less media.
