WSP 1/3 cu. ft. Filter Media

Notice a sharp chemical taste when you drink water or spot a dull film on your glassware? This comes from chlorine and heavy metals lingering in your water. The WSP 1/3 cu. ft. Filter Media is the material inside your tank that helps reduce these unpleasant elements, improving your water's taste and protecting your plumbing system.

The moment it affects your daily routine

You might first realize something’s off when a guest comments on the taste of your tap water or when the kitchen sink starts showing stubborn stains that just won’t scrub away. These signs come from chlorine and heavy metals in the water, leaving behind an unpleasant odor and a lingering chemical taste. You may also notice your glassware losing its sparkle or faucets developing an unusual film. This is water telling you it needs better treatment.

What the control head actually does

At the top of your system is the control head, a smart device that keeps the filter media clean and effective. It automatically initiates a backwash cycle that lifts and rinses the media bed, flushing out trapped contaminants. This process restores the media’s ability to treat your water without you having to intervene frequently, saving you effort and ensuring consistent water quality.

The filter media inside your tank

The heart of this system is the KDF-55 filter media—a specially formulated redox media designed to reduce chlorine and heavy metals. Redox stands for reduction-oxidation, a natural chemical reaction that changes harmful substances into less troublesome ones as water flows through the media. This media also helps suppress bacterial growth within the tank, keeping your system cleaner for longer.

Tank size and what it means for your home

The media fills a standard 13-by-54-inch tank, holding about three cubic feet of filter material. This size is substantial enough to treat water for a typical household, providing a steady flow of filtered water before the system needs to backwash and recharge. It balances capacity and space, fitting comfortably in most basement or utility areas without dominating the room.

The right fit for your water needs

This filter media suits residential water treatment systems designed to reduce chlorine and heavy metals while controlling scale buildup and bacteria in the media bed. It works well in single-family homes that want to improve water taste and protect plumbing without frequent maintenance. If your home demands higher volume or specific water challenges beyond what this media handles, consider sizing up or exploring additional treatment options.
