Sparkling Water vs Seltzer vs Club Soda
Seltzer is plain carbonated water, club soda has added minerals/salts, and sparkling (mineral/spring) water is naturally sourced with its own minerals. All are fizzy water — the difference is the source and what's added.
Quick comparison
- Seltzer: water + CO₂, nothing else.
- Club soda: water + CO₂ + added minerals (sodium).
- Sparkling spring water (NEA): real spring water, carbonated, naturally mineral-rich, no additives.

Which is cleanest?
For taste and natural minerals with nothing added, sparkling spring water wins. See NEA canned sparkling water →
