Including filter system and high-performance Tannins filter.
Tannins are natural organic compounds that can give water a yellow, amber or tea-like hue. They commonly enter groundwater after it passes through decaying leaves, peat or certain soils, and can leave water looking discolored even when it tastes only mildly different. In Leonia households you may spot tannins as an earthy or musty note in tap water, or see faint staining on fixtures, laundry and appliances over time if the compounds aren’t addressed.
Because tannins dissolve into the water, they won’t settle out like sand and can pass through simple cartridge filters. Many Leonia homeowners first notice tannins when clear glasses take on a tint, white laundry shows a yellow cast, or soaps don’t rinse away as expected. Tannins can also interact with iron to make discoloration and staining more obvious. The best way to know if tannins are present is a water test, so you can match the right treatment to your results.
For whole-house tannin control, the most effective single-filter option is an anion exchange system formulated for tannins. These systems use a specialized resin that attracts and holds negatively charged organic molecules, removing the color-causing compounds before water reaches every faucet in your Leonia home. Compared with standard carbon filters, anion exchange is generally more effective at eliminating the dissolved, tea-colored tint tannins produce. Installed at the main water entry, it helps protect plumbing, fixtures and appliances throughout 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 water softener, it requires periodic regeneration to flush away captured organics and restore resin capacity. If your water also shows signs of iron, sulfur odors or sediment, treating those issues alongside tannins will help stop staining from returning and improve overall clarity. Mr. Pure Water can assess your Leonia water test and household demand to recommend the right whole-house configuration.
