The USTM BL replacement filters are made from high-quality compact activated carbon.

Due to its porous structure, carbon is ideal for filtration. Contaminants found in water that flow through the activated carbon are trapped (adsorbed) in the pores, resulting in water that is purified and free from toxins.

They very effectively remove unwanted contaminants from the water and improve the taste and smell of the water. They also reduce chlorine and organic substances and effectively remove sediments.
