Air Fryers & Staying Safe
Let's start with the good news: air fryers earned their hype.
If you own one, you already know why. Dinner in 15 minutes instead of 40. Crispy food using a fraction of the oil. No vat of hot grease to deal with, no lingering fried smell in the house, and a basket you can rinse in the sink afterward.
They've genuinely made preparing delicious meals easier for millions of people. But there's one part of the conversation that rarely comes up, and it has nothing to do with the food you put in — it's about what the basket itself is made of.

The Coating Question
Most air fryer baskets are lined with a non-stick coating. Usually that's PTFE, better known by the brand name Teflon — which belongs to the family of chemicals known as PFAS, or "forever chemicals."
Here's where it gets nuanced, and we want to be straight with you about it.
Under proper use, most experts say the risk is relatively low. Professor Oliver Jones, a chemistry professor at RMIT, points out that PTFE is a very large, stable molecule that doesn't really interact with systems in the body, and air fryers typically run well below the temperature where these coatings start to break down.
The concern is what happens when that coating gets damaged.
Elvis Okoffo, a research fellow at the Queensland Alliance for Environmental Health Sciences, puts it plainly: the greatest risk arises when the non-stick coating becomes damaged. And the research behind that is striking — studies have found that a single scratch on a Teflon-coated surface can release upwards of 9,100 microplastic and nanoplastic particles during cooking.
One scratch. Which is worth thinking about, because how many of us have run a metal fork through a basket, scrubbed one with an abrasive sponge, or kept using one with visible chips and flaking?

The Cheaper-appliance Problem
There's a second issue that gets less attention, and it's about where the materials come from.
Some lower-cost appliances are built using recycled plastics — and recycled plastic sourced from electronic waste can carry substances you'd never want near your dinner, including antimony, cadmium, chromium, mercury, lead, flame retardants, and phthalates.
Reputable brands sold in the US, Canada, and EU are subject to strict regulations limiting lead and cadmium, so this is much more of a concern with unbranded or ultra-budget models than with established names.
Worth noting: there's been a wave of viral social media claims about specific major-brand air fryers testing positive for lead. Several of those claims were contradicted by other people testing the same models. We'd take that genre of content with a large grain of salt — the more grounded concern is material sourcing in no-name appliances, not name brands.
One more thing: acrylamide
When starchy foods like potatoes and bread are cooked above about 120°C, a compound called acrylamide forms. That's not unique to air fryers — it happens with roasting, baking, and especially deep frying.
In fact, here's a point in the air fryer's favor: air frying produces roughly 30–40% less acrylamide than deep frying.
But it still forms, and the research is consistent about what drives it: higher temperatures and longer cooking times mean more acrylamide, regardless of method. A study on air-fried legumes found a clear correlation between longer roasting times and higher acrylamide levels.
Practical takeaway: aim for golden, not dark brown. Soak cut potatoes before cooking. Don't overshoot the cook time on starchy foods.

So what's actually safer?
If you're shopping for a new one, the food-contact surface is what matters:
🥇 Stainless steel — no coating at all, nothing to chip or degrade. You'll need a little oil, but it's essentially bulletproof.
🥇 Borosilicate glass — completely inert, no coating, no chemicals. Fully visible cooking is a nice bonus.

🥇 Borosilicate glass — completely inert, no coating, no chemicals. Fully visible cooking is a nice bonus.
🥈 Verified PFAS-free ceramic — easier to clean than bare stainless, and avoids PTFE entirely. The key word is verified — look for brands that explicitly disclose PFAS, PFOA, PTFE, and BPA-free status on all food-contact surfaces.
Brands that have been recognized for transparent materials disclosure include Fritaire (tempered glass bowl, stainless accessories), the Wonder Oven Pro (stainless basket and rack), and Typhur Sync (PFAS-free ceramic).
And if you're keeping the one you have:
✅ Inspect the basket. If the coating is scratched, chipped, or flaking, it's time to replace it
✅ Use silicone, wood, or plastic utensils — never metal
✅ Skip abrasive sponges and steel wool; soft sponge and warm soapy water only
✅ Don't stack or nest baskets where they can scrape each other
✅ Avoid preheating an empty basket at max temperature
✅ Cook starchy foods to golden, not dark
Most of the risk here is avoidable with a quick inspection and a change of sponge.

One Last Thought
If you've been cooking on a scratched basket for a while, or you've had a cheap air fryer in rotation for years, you may want to think about helping your body to bind and flush toxins that could accumulate in the body.
It all adds up. It's the scratched pan, plus the plastic containers, plus the tap water, plus the packaged food, plus everything in the air. Your liver, kidneys, and gut handle all of it, quietly, every day. They're remarkably good at it. But they work better when you actually support them.
That's exactly what our Detoxification Protocol was built for — Detoxify, Super Greens, and Paratox working together to support your body's natural detoxification pathways, your gut, and the daily cleansing processes doing the heavy lifting behind the scenes.
Adding a little support for the systems already doing the work goes a long way.
