WSP Tannin Filter, TANNIN

Yellow or tea-colored water can make your laundry dull and dingy, leaving clothes looking worn before their time. The WSP Tannin Filter from Water Softener Plus helps reduce tannins and organic color in your water, so your fabrics keep their true colors longer and feel softer after washing.

How discolored water affects your laundry and home

Your washing machine might be doing more harm than good if the water has a yellow or brown tint. That tea-colored look comes from tannins—natural compounds that wash into your water from soil and vegetation. Over time, these tannins can dull colors and leave fabrics feeling rough or stiff, no matter how much detergent you use. You may notice whites becoming yellowed and colors looking faded. The residue can also build up inside your washing machine and plumbing, increasing cleaning needs and reducing equipment longevity.

The automatic control head that manages treatment cycles

The system’s control head runs all the key cycles automatically. It handles the regular service flow when you’re using water, then switches to backwash and rinse cycles when needed to clean the media inside. This automatic cycling is timed and controlled to keep the filter working efficiently without you needing to adjust anything. By managing water use and regeneration, it helps reduce waste and saves salt or other recharge materials over time.

Specialized media designed for tannins and hardness

Inside the tank, a cubic foot of carefully selected ion exchange resin works on two fronts. One part, the cation exchange resin, targets hardness—those calcium and magnesium minerals that cause scale and soap scum. The other component, a blend of anion exchange resins, focuses on tannins and dissolved organic matter that cause the yellowish color and earthy taste. This combination helps reduce both scale and discoloration, improving water clarity and feel throughout your home.

A tank built to last with enough capacity for small homes

The 9-inch by 48-inch tank holds the 1 cubic foot of resin that treats your water. It’s sized for typical small households—usually one or two people with one or two bathrooms. The system can handle about 5 gallons per minute during normal use, which comfortably supports daily activities like washing clothes, showering, and cooking without slowing down.

Who benefits most from this tannin filter

This system suits small homes where tannins cause noticeable yellowing and staining in laundry and around fixtures. It’s a good fit if you have one or two bathrooms and a household water use consistent with a couple of people. Larger households or those with higher flow demands will want to consider a bigger unit designed for higher capacity to avoid flow restrictions and frequent regenerations.

What comes with your WSP Tannin Filter

You get a pressure tank covered by a lifetime warranty, so the main vessel is protected for as long as you own your home. The control valve and electronics have their own manufacturer warranty. A bypass valve is included at no extra cost, so you can isolate the system during maintenance without losing water service. Also included is a 10-foot discharge hose for the drain line, making installation straightforward for your plumber.

Who this size is right for

This is rated for roughly 5 gallons per minute of service flow, which suits a small home - around 1-2 people with 1-2 bathrooms.

Flow rate matters more than tank size here: add up the fixtures that could realistically run at the same time and make sure this covers them. If you land close to the limit, go up rather than down.
