Pampers Pure diapers contain less chemicals than other disposable diapers.
No disposable diaper is 100% chemical free but Pampers Pure diapers are Paraben Free, Latex Free and Chlorine Free so they're much better for your babies skin especially if your baby is more prone to breakouts from chemicals or has a latex allergy.
If you want 100% free of chemicals diapers then you'll need to use cloth diapers that are reusable and washable.
But Pampers Pure are a good diaper for babies with sensitive skin and for those babies or toddlers that have a latex allergy.
