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 the highest-certified dishwasher tablet with zero ethoxylated surfactant exposure.
You have hard water and don't want to buy a separate rinse aid.
You value a transparent 10-ingredient INCI verified by EWG scientists.
A $24/load price point works for your household budget.
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.
Blueland earns a perfect 10.0 — the top score in this category. EWG VERIFIED + MADE SAFE, alkyl-polyglucoside formula (no dioxane), built-in rinse action, $0.35/load. No significant trade-offs for the target buyer.
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 specifically need a pod format (not a tablet).
You want the absolute cheapest option (Earthley is $0.30/load).
Neither of these quite what you're looking for?
