TST's SC Series aftermarket replacement filters are compatible with most Hydrotech, Clack and Culligan RO systems- Our filters are produced using only the best available materials and with an unparalleled attention to quality. The result is superior products having high capacity for chlorine, taste and odor reduction and efficient sediment and particle reduction.

Sediment Filters
Unique filament matrix provides excellent dirt holding capacity extending the life of the sediment prefilter. Our gradient depth filter captures larger particles on the outside while smaller particles are retained inside the filter matrix.

Carbon Block Filters
Our Carbon Blocks use high activity Coconut Shell powders, Advanced Binder Technology, and a unique compression molding process resulting in industry leading performance and contaminant reduction capabilities.
