Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You trust European certification standards (NCP, Eco-garantie, EcoControl, Vegan Society) and don't require US-specific verification.
You prefer enzyme-free formulas (allergy, philosophy, or simplicity preference).
You have hard water — Sonett's four built-in chelators provide strong mineral binding without a separate rinse aid.
You want MADE SAFE + EWG VERIFIED dual certification — the strictest available combination.
You prefer a PVA-free tablet with a mineral-dominant, non-ethoxylated formula.
You have soft or medium water, or you already use a separate rinse aid.
The main thing to know
R3's certification score understates Sonett's actual safety quality because European certs (NCP, Eco-garantie) don't map to the US-centric enum. The formula is genuinely clean and the enzyme-free philosophy is a feature for some households. Ideal for European-cert-trusting, enzyme-skeptical families willing to pay $0.68/load.
The top dual-certified (MADE SAFE + EWG VERIFIED) tablet in the category. The only deduction is a missing explicit hard-water performance claim despite the water-softening ingredient in the formula. Performance is nearly identical to Blueland; choose based on surfactant preference (mineral-only vs APG) and whether you need built-in rinse action.
Skip this if you...
You require EWG Verified, MADE SAFE, or EPA Safer Choice certification specifically.
You regularly run heavily protein/starch-soiled loads — enzyme-free formulas underperform here.
Budget is a priority — at $0.68/load it is the second most expensive formula in this category.
You have hard water and need a product with an explicit hard-water performance claim.
You need the absolute lowest price per load ($0.39 vs $0.30 for Earthley).
Neither of these quite what you're looking for?
