Smart and Efficient Filtering Technology

Tannin filtration systems are designed to effectively treat discolored water which can be found in well water sources.

A tannin system can provide the quality water you want without the unwanted minerals, discoloration, odors, tastes or acidity. These filters are manufactured to use water efficiently to conserve your water supply and preserve your well and its components.

Your water is unique, so choose a filtration system that is tailormade for your water. You can be confident that a tannin unit from One Green Filter will clear up your water once and for all.

What are Tannins?

Tannins are decomposed organic matter that give water “color,” often caused by vegetation. Plants, bark, and even roots in the ground can change your water to a light yellow or tea color. In fact, the coffee and tea you drink every day are considered tannins. Naturally, tannins are typically found in groundwater wells and can contribute to a musty, “earthy” smell and taste in your water.

Tannin filters from One Green Filter are proven successful in effectively removing any tannins commonly found in well water. They will help prevent staining of your laundry, and create clean, refreshing water with one efficient system.
