## Languages
foreverpure.com is localized into 10 languages with reciprocal hreflang. Nine are complete: 73 of the 80 published pages exist in all nine of English, Spanish, French, Italian, Portuguese, Vietnamese, Arabic, Simplified Chinese and Tongan, including every product, brand, system-capacity, industry, project, policy and engineering-resource page. The only gaps are on the blog: the containerized-BESS buyer's guide and the PFAS-removal article are in English, Spanish and Simplified Chinese, and the remaining five posts are English-only. A page missing a locale declares hreflang for English and x-default only, so an alternate is never advertised for a page that does not exist. Thai (/th/) was added on 2026-08-22 and is still being rolled out page by page; it is a machine-assisted translation that has not yet been reviewed by a native Thai speaker, and only the pages already published in Thai advertise a th alternate.
