The Hydro Guard HDGT-45 by Hydronix is a 4-stage RO System offers the filtration quality of a 5 stage RO system with only 4 easy-to-replace filters. The Hydro Guard HDGT-45 is easy to install and requires no tools to change filters and features a 4.5 Gallon Storage Tank. Added benefits include Shok Blok - a system-wide protection valve designed to protect the RO system from water pressure spikes and water hammer; and Flowlok - a unique compressed filter disc that expands on contact with water, acting as a leak detector shut off valve to turn off the system when water is detected. The HDGT-45 offers a twist and lock filter system allowing for quick and easy replacements of the 4 stages that feature a 5 micron sediment pre-filter, a 5 micron carbon block, a 50 GPD RO Membrane, and a carbon post-filter.
