In testing to find the best soda water makers, it mostly came down to general performance, ease of use and overall value. I made at least 10 full bottles of sparkling water using each, noting how proficiently and consistently a machine executed its most vital duty of imparting CO2 into water. I also carbonated other liquids including fruit juice and wine, but found that there was really no difference in performance based on the type of liquid being carbonated. If a machine carbonated water well, it did so across all liquids.
Some of the machines took more muscling and pumps of the lever to get CO2 emitted into the bottles. Of the manual machines, the SodaStream models were the most consistent. But with five unique settings, the Spärkel electric seltzer maker made the most precise soda water.
I also took note of the sturdiness and build of each soda water maker. The Aarke III is by far the most stylish soda water maker and is built solidly out of stainless steel with five finishes to choose from. While aesthetics are nice, it’s also by far the priciest model with a $200 tag, which keeps it from being the best model for most people.
