Our filters are made with a ceramic shell, high-flow carbon block, and granular activated carbon. While many competitive filters only use carbon elements, our hybrid approach to water filtration works to effectively reduce harmful contaminants while maintaining a strong flow rate.

The more filters you use, the more capacity you get. Choose what fits your needs and scale as you go.
