Global Water G3 Water Cooler Dispenser

The G3 is amongst the few water coolers on the market that come with an advanced water filtration system. Unlike the other units, this Global Water dispenser comes with a 4-stage Reverse Osmosis filtration system which is the most effective water purification method. It’s a perfect option for those living in areas where the water has very high levels of contamination.

Key Features:
  • Heats and cools water to right temperatures
  • Runs quietly and dispenses water fast
  • Effective 4-stage Reverse Osmosis filtration

Functions

There are only two dispensing functions on the G3 cooler, hot and cold. The compressor and heating element of the unit do their jobs well according to the reports of a majority of users.

The cold water is properly chilled and the hot water is hot enough to make hot drinks. The flow rate for both the cold and hot water is fairly fast too as you can fill an 8 oz. container in 10 seconds.

The unit also takes less time to heat and cool water. The hot water reservoir has a 1.8 liters capacity and it takes less than 5 minutes to heat the water to boiling temperature. The cold reservoir can hold 3.7 liters and takes 15 to 30 minutes to get chill water once emptied.

You won’t have any issues with regard to noise because the heating and cooling operations run relatively quiet.

Filtration

Filtration performance is the area where this Global Water cooler beats the other units on our list. The G3 gives you a complete 4-stage reverse osmosis (RO) filtration system that comprises a sediment filter, a pre-carbon filter, a RO membrane, and a post-carbon filter.

In the 1st stage, the sediment filter eliminates all particles and sediments from the water down to 5 microns. The 2nd stage is the 10-micron pre-carbon filter which removes chlorine, lead, and other chemical contaminants. It also clears out foul odors, tastes, and water discoloration.

From there, water goes through a 50gpd RO membrane (thin film composite) in the 3rd stage. This effectively removes over 90% of the remaining contaminants in the water including microorganisms (bacteria, viruses), harmful chemicals (chloramine, VOCs, pharmaceuticals), heavy metals, and dissolved solids (calcium, sodium).

From the RO membrane, the water passes through a 10-micron post-carbon filter in the 4th stage where any residual chlorine and other chemicals that slipped through the RO membrane are cleared out.

This effective 4-stage RO filtration process cleans your water thoroughly leaving it free of contaminants and tasting much better. You will notice a significant difference in the taste and quality of the water you get.

Furthermore, the three EZ twist filters have a long lifespan requiring replacement every 6 to 9 months. The RO membrane filter is equally durable. You need to replace it only after every 3 years.

Operating

Operating the G3 is really easy because it uses pushbuttons for dispensing water. The best part is that they are mechanical pushbuttons rather than electronic which means even in case of a power outage, you can still dispense water. This is very useful especially if you reside in an area that often experiences rolling blackouts.

The hot water button has an extra safety button on it that helps prevent kids from dispensing the hot water and getting burned. The unit also has two rear switches for turning on/off the hot or cold function.

The dispensing area has ample space and will fit large cups and containers. However, the spouts are not quite visible since they are level with the ceiling. Filling a bottle particularly at night might be tricky because you can’t see where water is coming out from.

Installation

Installing the G3 is a bit challenging than the other units since it features a reverse osmosis system that needs to be connected to two lines – a supply line and a drain line for wastewater.

It’s not super difficult but will definitely require some level of plumbing expertise in order to avoid damaging fragile parts. If you have no plumbing knowledge, you will have to hire a professional to install it.

The one critical downside is that the unit is entirely constructed using plastic. There are no metal components. It does feel somewhat solid but durability is not really guaranteed.

Verdict

Equipped with a reverse osmosis filtration system, the Global Water G3 water cooler dispenser is a superb unit to consider if water contamination is of major concern to you. This will ensure you have cleaner, purified water throughout.
