These days one can never be too careful when it comes to consumer products. Whether it's baby shampoo that actually contains formaldehyde or lead paint in children's toys, there's a lot of very valid reasons to be cautious about the products you are exposing yourself and your loved ones to. One of the questions we regularly get from folks regards the construction and interiors of our dehydrators. Are they really ALL stainless steel? Oh yes. Over thirty pounds of it! It's not steel plated or steel coated. It IS steel. 304 Food Grade Stainless Steel. The interior is constructed from the exact same material as the exterior for years of durability, and enjoyment with no leeching or off gassing. There's no plastics, BPA, Polytetraflouroethylene (Also known as PTFE or Teflon) or "Surgical Grade Polypropylene" as some many other companies use. No gimmicks. So if an entirely stainless steel dehydrator is what you've been seeking, your search is over!
