aarke (425g / 60L, 2-Pack) CO2 Carbonator Soda Machine Refill Cylinder | Compatible with All aarke Carbonator & Most Soda Machines | Makes Up-To 120L of Carbonated Water

The CO2 cylinder seems good. Works fine. It has the standard screw top that is compatible with my MySoda machine.

They work as expected. Great value. Easy to replace and install.

Excellent quality. Good service. Easy to use. The initial expense (for the Aarke Carbonator 3) is worth it in the long run. If you have tap water that has a good filter (reverse osmosis filter), and you zap it with the CO2, then when it's in a glass, sprinkle in a little non-refined salt (like Himalayan or better yet Maldon salt), voilà!--You get clean, excellent tasting mineral water. Plus, we no longer need to lug bottles of water into the house or worry about plastics which are present in all commercial mineral waters (e.g., Gerolsteiner, San Pelegrino, both of which we used to drink).

These work great. But now I need to find a way to return the empty canisters.

Thee canisters work the best with the Aarke carbonator 3. I absolutely love fresh seltzer! Better than the cans any day
