Suited for mains pressure installations

The Hydro Guard HDGT-45 boasts a 4-stage reverse osmosis (RO) system, delivering filtration quality equivalent to a 5-stage RO system. It simplifies maintenance with its user-friendly design, featuring four readily replaceable filters. 

The Hydro Guard HDGT-45 is easy to install and requires no tools to change filters, plus it features a 4.5-gallon storage tank. Added benefits include "Shok Blok"- designed to protect the RO system from water pressure spikes; and "Flowlok" a unique compressed filter disc that expands on contact with water, acting as a leak detector to turn off the system when water is detected.

The HDGT-45 offers a 4-stage filtration that includes a 5-micron sediment pre-filter, a 5-micron carbon block, a 50 GPD RO Membrane, and a carbon post-filter. See the replacement kits below.
