HydroGuard HDGT-45 Series 4 Stage RO System

Enjoy clean, safe drinking water with the HydroGuard HDGT-45 reverse osmosis system. This system offers the filtration capabilities of a conventional 5 stage RO system, with the advantage of less filters to replace making it a more cost effective system. It reduces the levels of lead, nitrates, cysts (cryptosporidium, giardia), arsenic, sodium and other contaminants commonly found in unfiltered tap water. Enjoy twice the flow rate compared to the standard HydroGuard HDGT-45 model – upgraded 3/8″ tubing enables water to come out of your faucet much quicker.

This reverse osmosis system is easy to install, and uses sanitary quick change filters which makes changing water filters fast, convenient and sanitary. One of the revolutionary features of the HydroGuard HDGT-45 is its leak detector shut off valve (FLOWLOK ™) which silently guards against any water leaks which may occur. It also has a water pressure regulator to protect your system from water hammer and spikes in water pressure. The HydroGuard HDGT-45 features a compact design and delivers quality water from your tap whenever you want it.

Filtration Process

Mechanical - A physical barrier traps particles to remove them from water.

Adsorption - Traps particles and some dissolved contaminants through physical and chemical interactions.

Ultrafiltration - Removes ultrafine particles and bacteria.

Multi-stage - Multiple filter stages that target specific contaminants.

Reverse Osmosis - Removes all contaminants to produce pure water.

Alkaline - Increases alkalinity (pH) and antioxidant level.

Reverse Osmosis, Multi-stage
Type of Filter

Activated Carbon Block - Removes chlorine, organic compounds, and other contaminants from water.

Catalytic Carbon - Removes chloramines and some heavy metals; more effective chlorine and organic compound removal than activated carbon block filters.

Anti Scale - Prevents hard water scale and corrosion.

Sediment - Removes suspended particles such as sand, dirt, rust, and sediment from water.

Pleated - Removes bacteria, viruses, ultrafine particles, and other contaminants from water.

Granular Activated Carbon - Removes chlorine and some other contaminants; less effective particulate filtration compared to carbon block filters.
