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 rain moves through decaying leaves, peat or certain soils, so well water in and around Old Town can pick up that coloration. You might not always notice tannins by taste alone, but they can lend an earthy or musty note and make tap water look uninviting. Over time tannins also leave stubborn stains on fixtures, laundry and appliances if left untreated.
Because tannins are dissolved organic compounds, they won’t simply settle out like grit and can pass through basic cartridge filters. Many Old Town homeowners first notice the issue when drinking glasses look tinted, white clothing develops a yellow cast, or soaps don’t seem to rinse clean. Tannins can also interact with iron and make staining or discoloration more pronounced and trickier to diagnose. The surest way to know if tannins are present is a water test, then select treatment that matches those results.
For a whole-house solution, an anion exchange system formulated for tannins is the most effective single-filter choice. These units use a specialized resin that attracts and holds negatively charged organic molecules, removing the color-causing tannins before water reaches taps throughout your Old Town home. Compared with standard carbon filters, anion exchange is typically superior at eliminating the dissolved tea-colored tint tannins create. Installed at the main water entry, it helps protect plumbing, fixtures and everyday water use across the house.
An anion exchange tannin filter performs best when paired with appropriate prefiltration and correctly sized for your household so it won’t clog or channel. Like a 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 will reduce recurring staining and improve overall clarity. Mr. Pure Water can review your Old Town water test and household needs to recommend the right whole-house configuration.
