The Ninja Pro AF141 is a small, 5.1-quart air fryer with enough capacity to cook for two to three people at once, and a compact design that suits cramped kitchens. It's a fairly simple model, with just four preset cooking modes: Air Fry, Roast, Reheat, and Dehydrate. It doesn't include a preheat setting or a shake reminder.
Our Verdict
The Ninja Air Fryer Pro 4-in-1 cooks frozen French fries very evenly. Although it doesn't have the largest overall capacity, this 5.1-quart air fryer has more surface area in its basket than many similar-capacity options, giving you enough space to spread a portion of frozen fries in a single layer. Each batch comes out quickly and mostly crispy, with just a small portion remaining mushy and a few pieces burning. Fresh-cut fries provide more of a challenge. When you make homemade hash browns or potato wedges, they cook quickly, and most still come out crispy, but not consistently throughout the batch. They also take up more space, so you're limited on how much you can make at once. Of course, the flipside of this model's smaller capacity is that it takes up less counter space, which is a welcome feature when you're just making a quick side of fries.
Leaves frozen fried foods mostly crispy.
Leaves higher-water-content foods pretty crispy.
Cooks a variety of foods fast.
Compact design fits in small spaces.
Moist or bulky foods end up with some under-browned areas.
Somewhat small capacity can only accommodate 2-3 portions at once.
The Ninja Air Fryer Pro 4-in-1 makes wings that are mostly crispy. You get the best results with precooked wings, which crisp up quickly and quite evenly, leaving only a few pieces under- or overcooked. However, fresh or brined wings don't crisp up as consistently, so more of each batch comes out underbrowned and rubbery, though they still cook pretty quickly, and they come out tender and moist. Whether you're cooking fresh or frozen wings, it can be tricky to arrange them in a single layer, so you can't make very many at a time without sacrificing performance.

The Ninja Air Fryer Pro 4-in-1 makes mostly crispy air-fried food. It's best suited for frozen fried foods like fries, nuggets, and taquitos, which come out mostly crispy, with just a few mushy or burnt pieces. It also does a decent job with heartier fare. Fresh veggies and proteins don't come out quite as crispy, but most of the batch still browns evenly, and proteins stay tender and juicy throughout cooking. The stable cooking temperature also helps leaner proteins cook at a lower heat without drying out, but it doesn't get hot enough to evenly sear a steak or completely crisp up a batch of wings. That said, this air fryer is a versatile pick. While its maximum temperature isn't as high as many other options, it gets low enough for proofing dough or dehydrating, and it can reach a wide enough range of fan speeds for most uses.

Differences Between Sizes And Variants
The Ninja AF141 comes in one color: Gray. Here's a photo of our unit's label. The Ninja AF140 is the Ninja Air Fryer Pro 3-in-1 and is identical to the AF141, except it doesn't have a 'Roast' function, which lets you set the timer to up to four hours. Otherwise, we expect our results to be valid for that model.
If you encounter another variant, let us know in the comments, and we'll update our review.
Popular Air Fryer Comparisons
The Ninja AF141 is a compact 5.1-quart air fryer with enough space to cook two to three portions at once, depending on the recipe. It's a good choice if you don't have much room to spare, since it uses its space very efficiently. Despite its larger capacity, it's almost as compact as the 4.5-quart Philips 2000 series 4.2L NA220/00, for example. The basket also gives you more room to spread food out than some air fryers with a larger overall capacity, such as the NutriChef 5.8 Quart NCAF539TB.
When it comes to performance, this air fryer stacks up well compared to the brand's dual-basket models. It makes frozen fries, onion rings, and chicken nuggets that are just as crispy as those from the Ninja DualZone DZ801, for example, and it does a better job with fresh veggies and proteins, leaving each batch juicier and more evenly crisped.

While the COSORI TurboBlaze and the Ninja AF141 provide good performance, the COSORI comes out ahead overall and is a better choice for most people. Whether you're cooking simple frozen snacks, like a plate of fries, or something heartier, like a batch of wings, your food comes out more evenly cooked with the COSORI. It offers greater versatility, too, so it’s a better choice for other cooking methods, such as baking, dehydrating, or broiling. On the flip side, the Ninja preheats and cooks faster and maintains a more stable temperature throughout the process, so you may still prefer it if you're looking for a fast air fryer.
The Ninja Pro AF141 and Ninja Air Fryer Pro XL AF181 are both impressive models from the brand, but they have small differences, and you may prefer either depending on your priorities. The AF181's taller cooking chamber provides a larger 6.5-quart capacity, but it doesn't increase the cooking surface area compared to the 5-quart AF141. This makes it great for taller items, but doesn't give you any extra room to spread food out. When it comes to frying quality, the AF141 comes out ahead, leaving more of each batch crispy and well-cooked. On the other hand, the AF181 cooks a bit faster. Both models are impressively versatile, with wide enough temperature and fan speed ranges for dehydrating on the low end or roasting on the high end.
The Ninja Pro AF141 and the Ninja Crispi Pro AS101 have different strengths, so you may prefer one over the other, depending on your priorities. Choose the AS101 if having evenly cooked food is your priority, since it leaves frozen fried foods, like fries or chicken nuggets, as well as fresh foods, like veggies or raw proteins, more evenly crispy across each batch. It also has a unique design, with swappable glass cooking chambers that double as storage, so you may prefer it if you're trying to save time on cleanup. Go for the AF141 if cooking speed is most important to you; it preheats and cooks a variety of recipes faster. It also leaves fresh proteins more tender after cooking.
The Ninja Pro AF141 is a better air fryer than the Ninja Crispi FN101GY for most people. The AF141 cooks frozen fried foods much more evenly, so it's a better choice if you want to use your air fryer for fries, chicken nuggets, or other precooked foods. It also cooks faster and offers greater versatility for other cooking methods, such as roasting or dehydrating. That said, the FN101GY provides better performance for vegetables and raw proteins, so you may prefer it if you mostly plan to make smaller mains and sides of veggies or if you prefer its design, which uses swappable glass cooking chambers that double as storage.
Test Results
The basket has enough surface area to spread out a portion of fries or onion rings without too many overlapping, but as a compact air fryer, it doesn't have room for very large batches, and you may struggle to arrange bulkier foods in a single layer. The crisper tray has a ceramic coating, which is nice if you want to avoid traditional non-stick materials, but it's not as easy to clean by hand as PTFE-coated trays.
With a capacity of 5.1 quarts, this air fryer can make two to three portions at a time. Unlike the crisper plate, which has a ceramic coating, the basket is lined with a PTFE nonstick coating. It's easier to clean if you don't avoid traditional nonstick coatings.
It offers excellent versatility, mainly thanks to its wide range of fan speeds. The highest fan speed is very fast, which helps crisp food quickly, and the lowest is quite slow, which helps prevent your food from drying out while baking or blowing around the basket while dehydrating. It also has a wide temperature range, though it doesn't get as hot as some air fryers. The different modes correspond with different fan speeds, and you can customize the cook time and temperature. Most of the time, you can adjust the cooking time in one-minute increments, but if you're using Roast or Dehydrate, depending on the total cooking time, you may only be able to adjust the time in five- or 15-minute increments.
- Air Fry: 1 – 60 minutes. Time is adjustable in one-minute increments
- Roast: 1 minute – 4 hours. Time is adjustable in one-minute increments up to one hour and five-minute increments beyond one hour
- Reheat: 1 – 60 minutes. Time is adjustable in one-minute increments
- Dehydrate: 15 minutes – 8 hours. Time is adjustable in 15-minute increments
This model air fries pretty evenly, so batches of frozen fried foods, like fries, spring rolls, and chicken nuggets, come out mostly crispy and golden brown, though a small handful don't crisp up enough, while a few pieces also burn.
This air fryer is a decent choice for cooking meat and poultry. At 400 °F, the maximum temperature is a bit low, which impacts how well the air fryer can crisp up fatty proteins that need high heat for quick crisping, like wings or a ribeye steak. While most of your food comes out crispy on at least one side, it's not consistently browned across the whole batch, and a couple of areas don't crisp up at all. That said, the temperature is very consistent, and proteins stay moist and tender throughout cooking, so you can expect better results with leaner proteins that require lower heat, like pork chops or chicken breast.
It cooks impressively fast. Small, frozen, fried foods cook especially quickly, but even thicker proteins and high-moisture vegetables cook quickly.
After adding food, it returns to temperature faster than most air fryers. It also maintains a very stable temperature during cooking, which helps you predict when your food will be ready, accurately follow recipes, and cook lean or delicate foods.
