The Steel CodCast
FreshFlow. HydroFresh. FreshSeal. ProduceSaver. If you've ever tried to explain produce preservation to a customer and ended up just reciting a branded name — this episode is for you. Jon Beresford breaks down the actual hierarchy of refrigerator food preservation: what matters, in what order, and how to tell the difference between a refrigerator that's genuinely engineered to protect produce and one with a shiny sticker on a leaky plastic drawer. The conversation starts where it should — the drawer itself. Does it seal? Does it have gasket material? Does it create a controlled environment or leak air like a storage bin? If you can't check that box, nothing else in the preservation story holds up. From there, Jon works through humidity balance (not just trapping moisture — managing the exchange), temperature stability (why inverter and variable speed compressors produce fundamentally different environments), produce separation from disruptive airflow (what dual evaporators actually do), and finally — only after all of that — the enhancement layers: ethylene absorption, air purification, and the branded filtration systems that brands love to lead with. Those enhancement layers are real when they're built on strong fundamentals. Sub-Zero didn't build their food preservation reputation on a cartridge. But when the fundamentals are weak, those features are just expensive distractions. Jon also calls out why this category has become a mess — manufacturers realized "keeps food fresher longer" sounds premium, created a thousand different names for it, and let salespeople use the chaos as cover for not actually understanding what they're selling. 👉 Our full air purification episode: https://www.podbean.com/eas/pb-hpiay-1aced2c 🎙️ Hosted by Shannon O'Hara and Jon Beresford | The Steel Codcast 🔔 New episode every day of the week.
