Is the Cosori TurboBlaze Ceramic or Teflon?

So here is the straight version, with the sources.

The short answer

For the CAF-DC601-KUS Dark Gray, Cosori states that the basket and crisper plate are PFAS-free ceramic. RTINGS reported PTFE on a TurboBlaze unit it tested, and its changelog later noted a switch to ceramic. Those sources describe different units and do not establish the coating for every TurboBlaze variant.

What nobody publishes is a way for you to tell which one is in the box before you open it. That is the honest gap, and it is covered further down.

What the manufacturer says

The exact model here is CAF-DC601-KUS, the 6.0-quart TurboBlaze in Dark Gray. Cosori's own product materials, checked 2026-07-26, state:

Cosori's matching replacement parts say the same thing. The official replacement basket (CRP-DC601RB-KUS) and the official crisper tray, both sold for the CAF-DC601, are each listed as ceramic-coated and dishwasher-safe. They corroborate the published specification for this exact model, not every TurboBlaze variant or every earlier unit.

What independent testing found

RTINGS published a hands-on test of the standard TurboBlaze (test bench updated 2026-02-20). The unit they measured reported PTFE—the material most people mean when they say Teflon. Their changelog notes Cosori subsequently moved to a ceramic coating.

Consumer Reports also has a lab entry for the exact CAF-DC601-KUS model. It does not settle the question: it records the basket only as generic “nonstick coating,” without naming ceramic or PTFE.

So the evidence lines up like this:

The part no one will tell you

There is no published way to identify which revision you are buying. We looked for one specifically: no cutoff date, no serial range, no packaging marking, and no model-number suffix that Cosori documents as a coating indicator.

You may run into a claim online that CAF-DC601 is the PTFE version and CAF-DC601-C is the ceramic one. We chased that down. It traces to a single page with no author, no citations, and no manufacturer backing, and the suffixes Cosori actually uses in the wild—-KUS for the US, -KEUR and -WEUR for Europe—behave like regional markers, not coating markers. We are not repeating that claim as fact, because it is not one.

What to actually do

If the coating is the deciding factor for you:

• Match the full model and color. This page's manufacturer evidence is for CAF-DC601-KUS Dark Gray. A listing for another model, color, region, or bundle may have different specifications.
• Read the listing you are actually buying from. If it says PFAS-free ceramic in the title or specifications, that claim applies to the listed product. It does not prove what was used on every TurboBlaze unit.
• If it matters enough, ask before you buy. A pre-purchase question to the seller about the coating on the unit they are shipping is reasonable, and their answer is worth more than any article—including this one.
• Check the replacement basket separately. Cosori lists CRP-DC601RB-KUS as ceramic-coated, but that replacement-part specification does not prove what coating came on the original unit.

One more thing worth knowing

While checking this model we found a separate discrepancy worth flagging, because it affects whether this fryer fits your dinner. Two independent labs disagree on how much it actually holds. Against a 6-quart claim, RTINGS measured 6.3 quarts and Consumer Reports measured 4.5 quarts. That is a 1.8-quart spread on the same product.

We are not going to reconcile that for you, because neither lab publishes enough about its method for anyone to honestly say which figure describes the space you will actually use. Treat 6 quarts as the optimistic number, and if you regularly cook for more than three people, plan around the low end.

Where to check the current listing

Because published coating evidence differs across units, check the full model, color, and specifications on the listing you are buying:

• COSORI TurboBlaze CAF-DC601-KUS on Amazon: as of 2026-08-14 this Dark Gray listing is sold by Amazon and its title reads “PFAS-Free Ceramic Coating”. Listings change, so confirm that wording and the exact model on the page you land on.
• COSORI genuine replacement basket (CRP-DC601RB-KUS): listed as ceramic-coated and dishwasher-safe for the matching model. Its specification applies to the replacement part, not necessarily the original basket in every unit.

Common questions

Is the Cosori TurboBlaze non-toxic?

For the CAF-DC601-KUS Dark Gray, Cosori states that the basket and crisper plate use a PFAS-free ceramic nonstick coating, checked 2026-07-26. That is a manufacturer statement, not an independent lab result, and it does not establish the coating for every TurboBlaze variant.

Is the Cosori TurboBlaze PFAS-free?

For the CAF-DC601-KUS Dark Gray, Cosori’s product materials and matching replacement parts list a PFAS-free ceramic coating. Consumer Reports lists this exact model with a generic “nonstick coating” and does not confirm either material.

Is the Cosori TurboBlaze dishwasher safe?

For the CAF-DC601-KUS Dark Gray, Cosori lists the basket and crisper plate as dishwasher safe, and the matching replacement basket carries the same rating. Handwashing can still reduce wear on a nonstick surface.

Is the Cosori TurboBlaze ceramic or Teflon?

For the CAF-DC601-KUS Dark Gray, Cosori currently specifies a PFAS-free ceramic coating. RTINGS measured PTFE, the material most people mean by Teflon, on a TurboBlaze unit it tested, so that result should not be generalized to this exact model or every other variant.
