Ensure the purity and safety of your water with Räyn, the premier high-flow water filter that removes up to 99.99% of viruses, bacteria, and parasites, effectively sterilizing water at the point of use.

An effective layer of protection for the immunocompromised and ideal for use in RVs, boats, and rental homes, Räyn delivers pure, safe, delicious water whenever and wherever you need it.
