Mirro Even Heating Aluminum 10" Nonstick PermaCote Manitowoc, WI
Skip; nonstick coating composition undisclosed, likely PFAS-based.
Mirro's PermaCote nonstick coating is not identified as Teflon-type coating-free or PFAS-free. Traditional nonstick aluminum cookware typically uses Teflon-family coating that contain PFAS.

Is Mirro Even Heating Aluminum 10" Nonstick non-toxic? What it is made of
This pan is aluminum with a nonstick coating branded as PermaCote, but Mirro has not publicly disclosed the Teflon-family coating chemistry or manufacturing standard of this coating. Aluminum cookware can leach aluminum into acidic or alkaline foods if the nonstick barrier degrades or is absent. The specific Teflon-family coating used determines PFAS risk; without disclosure, the coating's chemical composition and durability over time cannot be independently assessed.
What’s concerning
Non-stick, chemistry undisclosed
Marketed as non-stick without stating the coating chemistry.

The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Teflon-type coating fume risk (nonstick coating)
PermaCote composition is undisclosed; if Teflon-type coating-based, overheating above 500F can decompose the coating and release fluorinated gases. No specific data on this product's fume profile exists in public records.
Aluminum leaching
If the nonstick coating wears, scratches, or degrades, the underlying aluminum substrate can contact acidic foods (tomato sauce, vinegar, citrus) and leach aluminum. Mirro has not published durability or leaching studies for PermaCote.
Coating degradation over time
PermaCote is an older formulation (product appears to be from 1990s-2000s era cookware lines). No data on long-term coating adhesion, spalling resistance, or safe useful life is readily available; degradation accelerates with high heat and dishwashing.
What’s reassuring
Lead
No recalls or test reports documenting lead or cadmium in Mirro PermaCote nonstick coatings have been published. This does not confirm absence; testing would be required for verification.

The brand's record and disclosure
Mirro (owned by Groupe SEB) has not issued public statements on PFAS content, alternatives, or testing protocols for its nonstick coatings. The PermaCote line predates widespread PFAS transparency in the cookware industry and carries no third-party certification for coating safety or composition. No major recalls related to coating failure or leaching have been publicly documented for this specific product line, but the absence of a record does not confirm safety.
How it compares in its category
Most mass-market nonstick aluminum cookware of this era uses Teflon-type coating-based coatings with similar disclosure gaps. Ceramic or stainless steel alternatives eliminate nonstick Teflon-family coating concerns but require seasoning or accept lower nonstick performance. Brands like GreenPan, Our Place, and Caraway now disclose PFOA-free or ceramic formulations; Mirro PermaCote lacks equivalent transparency, placing it in the lower-clarity segment of the category.
If you buy it
Keep temperatures below 500F to minimize coating degradation and potential fume release from overheating. Inspect the nonstick surface regularly for scratches, peeling, or worn spots; discard if coating integrity is visibly compromised. Hand wash rather than dishwash to extend coating life. Replace within 3-5 years if daily use; older nonstick coatings are more prone to breakdown and leaching into food.
