WSP 1/3 cu. ft. Filter Media

If your water smells or tastes like chlorine or leaves stains and buildup from metals like iron or lead, the filter media inside your treatment tank is what actually does the work. This 1/3 cubic foot filter media from Water Softener Plus (WSP) helps reduce those issues by treating your water as it passes through.

The problem you’re living with

Your water might smell of chlorine, taste off, or leave rust-colored stains on sinks and toilets. You could be scrubbing residue from fixtures or noticing your clothes come out dingy even after washing. These are signs that your water contains chlorine and metals like iron or lead, which standard softeners or filters don’t fully address on their own.

Why it’s happening

Chlorine is commonly added by water suppliers to kill bacteria, but it leaves behind a strong taste and smell. Metals like iron, lead, and mercury can come from old pipes or natural sources underground. The filter media inside your water system is what interacts with these contaminants to reduce them. To confirm you have this issue, a simple water test revealing chlorine levels or metal presence is the best step.

What it’s costing you to leave it

Chlorine and metals don’t just affect taste and smell. They can cause staining on plumbing fixtures and laundry, reduce the lifespan of your water system by promoting scale and corrosion, and increase the amount of soap or detergent you need. Over time, that buildup requires more cleaning and can wear out appliances faster.

How this system fixes it

This filter media works through a chemical process called redox, where it changes chlorine and metals into less reactive forms or traps them inside the media. As water flows through the media bed, these contaminants are reduced, improving the water’s taste and protecting your plumbing and appliances.

What this system can handle

The 1/3 cubic foot size means this media bed can treat a moderate volume of water, suitable for many household water softeners or filtration setups. It effectively helps reduce chlorine and metals like iron, lead, and mercury, and also helps keep bacteria growth in check inside the system. Its durable structure supports continuous use without frequent replacement and fits into standard treatment drums designed for this volume.

What you actually get

This product is a 1/3 cubic foot drum of KDF-55 process media. This media is a chemically stable, eco-friendly material that uses a natural redox reaction to reduce chlorine, heavy metals, and bacterial growth inside your water treatment tank. The exact setup depends on your system, but this media is the core that does the treatment work inside the tank.

Is this the right size for you

If your system uses a 1/3 cubic foot media drum or if you have a medium-sized household water treatment setup, this size fits well. For larger systems or higher water volumes, you may need a bigger media volume; for small or point-of-use filters, a smaller size might be appropriate. Confirm your system’s needs before ordering to ensure compatibility.

Living with it

Filter media like this typically requires replacement based on water usage and contaminant levels, often after months or years of service. It demands minimal maintenance beyond periodic checks during your regular plumbing inspections. Because it’s durable and stable, it won’t degrade quickly, so you won’t need to replace it frequently.

What it won’t do

This filter media does not soften water or remove hardness minerals like calcium and magnesium. It also won’t filter out sediment or pathogens that require other types of treatment. If you need those, you’ll want to add a water softener or sediment filter alongside this media.
