This Our Place Wonder Oven review examines the brand's compact 6-in-1 countertop oven, the one people buy specifically to avoid a Teflon-lined air fryer. Its draw is a PFAS-free stainless interior with ceramic-coated accessories, a clever steam-infusion feature, and a small footprint. Air-fry performance is the weaker mode and the analog dial invites some guesswork. This research-based review covers what it is, how the steam feature works, what owners report, and how it compares to COSORI, Ninja and Breville.

The verdict, in one line
The Wonder Oven earns its place on non-toxic lists because Our Place states the interior is stainless and the surfaces are PFAS-free, unlike the Teflon-lined baskets in many air fryers. Add a genuinely useful steam-infusion feature and a small footprint and it is a smart convenience pick. The honest limits are that air-frying is its weakest mode, the analog dial runs approximate, and the ceramic-coated accessories are still coatings. Buy it for the surfaces and versatility, not for best-in-class crisp.
The Wonder Oven is a compact 6-in-1 countertop oven that air fries, toasts, bakes, broils, roasts and reheats, with a steam-infusion trick for baked goods.
Our Place built the Wonder Oven for people who want air-fryer convenience without a Teflon-lined basket. It combines six functions in one countertop unit, holds about 13 quarts, and fits a footprint of roughly 10.6 by 11.5 by 11.6 inches, small enough for most counters and big enough for a sheet of cookies or a couple of chicken breasts.
The signature feature is steam infusion: you add one to two teaspoons of plain water after the oven preheats, and the burst of steam helps bread and pastries keep a soft interior and better crust. Our Place is specific that it is a steam assist, not a full steam oven, and that only plain water goes in the reservoir.
It ships with a stainless interior and a ceramic-coated bake pan and air-fry basket, plus a wire rack. Controls are analog dials rather than a digital panel, which keeps it simple but, as owners note, trades away precise temperature accuracy. Variants include the standard Wonder Oven and larger or Pro configurations.
Wonder Oven at a glance
The reason this oven shows up on non-toxic lists is its surfaces. Our Place states the Wonder Oven has a stainless steel interior and that its interior and accessories are PFAS-free and PTFE-free, unlike many air fryers that use fluoropolymer-coated baskets. The EPA tracks PFAS as a large family of persistent chemicals, and the FDA regulates food-contact coatings, so a PFAS-free hot-air appliance is a genuine point in its favor.
The nuance is the accessories. The bake pan and air-fry basket use a ceramic non-stick coating, which is still a coating, and coatings are finite even when they are PFAS-free. It is a much lower-concern surface than PTFE for a hot appliance, but ceramic coatings do wear, so treat the included pans as replaceable parts and use gentle utensils.
"Non-toxic" is an unregulated term, so the honest framing is what Our Place discloses: a stainless interior and PFAS-free surfaces, with the usual caveat that ceramic-coated accessories are wear items. On the surface question, the Wonder Oven is a reasonable, lower-concern choice versus a Teflon-lined air fryer.

PFAS-free stainless interior, 6-in-1 with steam · a commission never changes our verdict
The Wonder Oven holds about 13 quarts in a footprint near 10.6 by 11.5 by 11.6 inches, which comfortably fits toast, a small sheet of cookies or a weeknight protein and vegetables. It is designed to preheat quickly and to sit on a counter without dominating it.
Controls are analog: dials for function, temperature and time. That keeps the interface simple and avoids a fragile digital panel, but owners consistently note the dial is approximate, so an oven thermometer helps if you bake precisely. Variants such as a larger model or the Wonder Oven Pro add capacity or features at a higher price.
The standard Wonder Oven covers most needs: the 6-in-1 functions, the steam assist and the compact footprint. If you cook for one or two, or want the smallest counter footprint, it is the value choice.
The larger and Wonder Oven Pro variants add capacity and, depending on configuration, features like a digital display, at a meaningfully higher price. Choose up only if you regularly cook for a crowd or want digital precision; the non-toxic surface story is the same across the line.
Because we do not cook with the oven, we synthesize aggregated verified-owner reviews. Owners like the compact size, the fast preheat, the PFAS-free surfaces, and especially the steam feature for reviving bread and baking soft-centered goods. Toast and bake modes draw steady praise.
The consistent criticisms are that air-frying is the weakest mode, less crisp and lower-capacity than a dedicated air fryer, that the analog dial runs warm or cool on some units, and that the fan is audible. None of these are safety issues; they are performance trade-offs for a compact, coating-light appliance.
The clearest reason to choose this oven is the surface comparison. Many popular air fryers use PTFE-coated baskets, part of the PFAS family the EPA and NIH/NIEHS track as persistent, and overheated non-stick can release fumes. A stainless interior with PFAS-free accessories avoids that category.
The honest caveat is that ceramic-coated accessories are still coatings, so they wear and should be treated as replaceable. For the most conservative setup, you can use the stainless rack and your own uncoated or ceramic pans and skip the coated accessories entirely.
This Our Place Wonder Oven review is research-based, not hands-on. We did not air-fry, toast or measure any unit. We synthesized Our Place's published specifications and PFAS-free surface claims, appliance material science on stainless and ceramic coatings, comparisons to competing air-fryer ovens, and aggregated verified-owner reviews, with primary sources cited for the safety framing.
What we cannot verify: real-world air-fry crispness, the exact temperature accuracy of the analog dial, and noise levels, all of which vary by unit and are owner-reported rather than measured by us. On price, the base model sits in the mid range for a countertop oven and the Pro runs higher; the value case rests on the PFAS-free surfaces and the six functions, not on best-in-class air-frying.
If air-fry crispness or capacity matters more to you than a PFAS-free interior, dedicated air-fryer ovens do that job better, though usually with a coated basket. Weigh the trade-off:
