It's easy to match your carbonation preferences by number of spritzes:

  • 1 Spritzes = light effervescent
  • 2 Spritzes = starting to sparkle
  • 3 Spritzes = average bubbles
  • 4 Spritzes = extra bubbly

Certainly - cold water is always better. However, using too much ice can have an impact on the efficiency of the carbonation, as ice can block CO2 from mixing with the water. It’s always best to add ice well in advance.

Please only carbonate plain water. If you would like to flavor your sparkling water, we recommend adding flavoring (fruit or flavor packets) after carbonating.

We also recommend cleaning your Aerflo System after it comes in contact with anything other than plain water. It'll keep things fresh and ready to use.
