Key Features and Benefits:

23 Cup Water Capacity

The number one thing we like about this water dispenser is that it comes with generous water capacity.

When full, it will hold a total of 23 cups, making it the largest refrigerator water dispenser you can find on the market.

This is the main reason why we recommend this unit to bigger families, offices or even sports fields where there are a high number of people who want purified drinking water.

Superior Water Filtration

This is not just any other water dispenser you’ve used before.

Unlike most of the units out there which use the standard water two-stage activated carbon filtration process, this filter uses the Next generation filtration system which takes your water through a total of 5 filtration stages for maximum removal of contaminants.

This is how the filter works:

First, the combines activated carbon plus oxidation-reduction to remove the chlorine smell and taste usually found in tap water.

In the next stage (ion exchange stage), where all the dissolved solids that might have been left over from the public water systems or have been leached into the water from lead, aluminum, and other piping types.

For your information, this filter has received NSF certification for reduction/removal of mercury, zinc, iron, copper, chlorine, lead, hexavalent, hydrogen sulfide, and aluminum in tap water.

Finally, your water goes three more additional stages to remove all the remaining impurities in water.

Thanks to the integrated, battery-powered TDS water quality meter, you’ll be able to test the quality of the filtered water to ensure you’re taking healthy, great-tasting water.

Most notably, it features a flip-up lid which facilitates easy refilling of water.

It also features a no-drip spout for easy pouring of filtered water into the glass. The on-hand pull & pour spout also contributes to the overall ease of use of this dispenser.

Unlike most dispensers that have a disadvantage of not dispensing all the water inside, this unit boasts of a unique shape which ensures that all the water inside is completely dispensed.

This means you’ll not have to worry about stale water in your unit.

Though we said that this water dispenser has a larger capacity than most of the other units out there, it doesn’t mean the unit has a bulky size.

It measures approximately 6-inches x 11-1/5-inches x 15-1/5-inches. It has a sleek, slim, space-saving design that neatly fits on a shelf inside your refrigerator or the counter.
