Hydro Guard HDGT-45 50 GPD 4-Stage RO Replacement Filters

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 simple twist and lock 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 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.

Helpful Filter Information

Not all filters have the same replacement schedule. Replace the RO membrane filter every two years. Replace all other filters every 6-12 months. Help keep your system sanitary by never using filters longer than 12 months, except the RO membrane filter, regardless of how much water you use.

Filter Replacement Schedule

We’ve taken the guesswork out of replacing your filters. Begin a filter replacement cycle by replacing all filters on your system (Filter Kit "YSM"). The following year, or sooner if recommended by the manufacturer, replace all filters except the RO membrane (Filter Kit "YS"). Repeat this cycle by following the helpful diagram below.
