Including filter system and high-performance Tannins filter.
Tannins are natural organic compounds that can give water a yellow, amber or tea-like tint. They commonly enter groundwater after water moves through decaying plants, peat or certain soils, and while you might not always taste them distinctly, tannins can lend an earthy or musty flavor and make water look unpleasant. Over time they can also leave stubborn stains on fixtures, clothing and appliances if left untreated in a Century home.
Because tannins dissolve in water rather than settling out, they often pass through basic cartridge filters. Many homeowners in Century first notice the issue when drinking glasses look tinted, white laundry picks up a yellow cast, or soap and shampoo don’t rinse away cleanly. Tannins can also interact with iron to make discoloration and staining more obvious and trickier to diagnose. The best step is a water test to confirm tannins and then choose treatment that matches the results.
For whole-house tannin control, the single most effective filter is an anion exchange system designed specifically for tannins. These units use a specialized resin that attracts and holds negatively charged organic molecules, removing the tea-colored tints before water reaches your taps. Compared with standard carbon filters, anion exchange is generally better at eliminating the dissolved color tannins produce; installed at the main water entry for your Century residence, it helps protect plumbing, fixtures and everyday water use.
An anion exchange tannin filter performs best when paired with proper prefiltration and correctly sized for your household so it won’t clog or channel. Like a water softener, it requires periodic regeneration to flush captured organics and restore the resin’s capacity. If your water also contains iron, sulfur odors or sediment, treating those issues alongside tannins can prevent stains from returning and improve overall clarity. Mr. Pure Water can review your water test and household needs to recommend the right whole-house setup for Century homes.
