What's the difference between the Glass Water System & Gravity Water System?

Edited

The main differences between the two systems are:

  • Material

  • Filtration functionality

  • Size

Here's a summary chart of their differences, with additional details on the differences below.

Filtration Rate for 1 Upper Tank

5 minutes

2-3 hours

8 L / 2.1 gal

10 L / 2.6 gal

Height

60 cm / 24 in

Material

The Glass Water System is made from a combination of glass, bamboo and stainless steel whereas the Gravity Water System is made from BPA/BPS-free plastic.

Filtration Functionality

The filtration of the Glass Water System and the Gravity Water System are very similar. They both filter 90+ contaminants, including chlorine, lead, fluoride, and VOCs.

The biggest difference is that the Gravity Water System uses a Ceramic Pre-Filter to reduce particulates like rust and sediment in water, whereas the Glass Water System does not. Since the Gravity Water Systems uses a Ceramic Pre-Filter, it offers the most comprehensive filtration, eliminating particles greater than 0.3 micron size.

The Ceramic Pre-Filter affects the filtration speed, so the Gravity Water System takes about 2-3 hours for one upper tank to filter through. Since the Glass Water System doesn't have a Ceramic Pre-Filter, it filters much faster: one upper tank takes about 5 minutes to filter through.

Size

The Gravity Water System is slightly taller and larger in capacity than the Glass Water System.

Gravity Water System size:

  • Height (countertop model) : 60 cm / 24 in

  • Capacity: 10 L / 2.6 gal

Glass Water System size:

  • Height: 43 cm / 17 in

  • Capacity: 8 L / 2.1 gal
