A:Answer The box and manual don’t say anything about it being BPA-free. Elsewhere on the Internet, I saw all the trays labeled as BPA-free, but not the base or lid. This is concerning, as the unit uses steaming to cook, and water condensed on the lid could have BPA leeched into it. Not happy about this, as add claims the entire thing is BPA-free. Elite Gourmet, please respond.
