I've cooked 2,000 meals in Air Fryers over the last five years, and Ninja is the brand my readers ask about more than any other. They make a dozen different models, and the names blur together. I've lived with the DZ401 DualZone, the Foodi Smart XL grill, and the original 5-quart Air Fryer Pro for months at a time, cooked the same 40 foods in each, and kept the spreadsheet to prove it.
Here's which one you should actually buy.
Why you should trust me
I'm Priya, and I've tested air fryers professionally for years after burning through three generations of loud, plastic machines in my own kitchen. My shop looks like a small appliance showroom, my beagle Chip sleeps on my lap while I cross-reference basket capacities, and I've bought Ninjas as gifts for my 87-year-old mom and my neighbor who cares for her 101-year-old husband.
I cook breakfast, lunch, and dinner in every machine I review for 30 days, and I measure the usable footprint, not the marketing numbers.
How I picked
The criteria were simple. Does it hold temperature within 10 degrees of the set point? Is the usable cooking surface actually big enough for a family meal? Does the coating survive a month of daily use? And would I trust it with my HungryMan's dinner every night? I ran my standard battery: the frozen fry test, the chicken thigh crisp test with a thermometer to check for pink at the bone, the cake test to reveal hot spots, and 30 days of real cooking.
I also cross-checked what actual owners were saying about basket alignment, noise, and cleanup, because a machine that sounds great on paper can fall apart in week three.

Visit on Amazon →Our pick: The Ninja DZ401 Foodi DualZone XL
This is the one I reach for when I need dinner on the table without a fight. I bought mine for ~$199, and I've used it twice a day since. The DualZone means I can cook chicken thighs in one basket and taters in the other, both at different temperatures, and everything finishes at the same time.
The Smart Finish feature is not a gimmick, it actually syncs the cook times so one basket isn't sitting around getting cold while the other finishes.
I made a full meal in 25 minutes last Tuesday: salmon at 390 in one side, asparagus at 400 in the other, and it all came out gorgeous.

The cake test passed, which surprised me. No hot spots, even golden brown across the top, no doughy center. The chicken thigh test was the real winner though: crackling skin, cooked through to 165 at the bone, no pink.
The ceramic coating has held up through a month of daily abuse, and melted cheese comes off with relative ease.
It's quiet enough that I have to check if it's on, which is my highest compliment.
A verified buyer in June 2026 said the same thing I've noticed, small items like fries can slip between the grates, but that's true of every drawer style air fryer I've tested. The baskets are dishwasher safe, which is non-negotiable for me.
Flaws but not dealbreakers: It's big. The footprint is substantial, and if your counters are cramped, this will dominate them. And the handle button took a bit of getting used to, you have to press it just right to release the basket. But the capacity is worth it. If you cook for more than two people, this is the one.
This is for the person who wants to cook a full meal in one appliance without babysitting it.
Runner-up: The Ninja Air Fryer Pro 5 Qt
I bought this one for my mom, and she made salmon cakes on day one. It's the simplest machine I've tested, one basket, five functions, no learning curve. The 5-quart capacity is honest, I measured the usable footprint and it actually holds four chicken thighs without crowding, which is more than I can say for some 6-quart baskets I've tested.
It runs quiet, holds temperature within 5 degrees, and the cake test came out even with no hot spots.

The presets are actually useful, which is rare. The reheat function brought back pizza with a crispy crust and melty cheese, better than the microwave ever did. And I dehydrated chicken for Chip in it, which took me back to the first air fryer I ever owned. The basket is dishwasher safe, and the ceramic coating has held up through 30 days of daily use.
At ~$119, it's the best value in the lineup. But it's not a dual zone, so if you want to cook two things at different temperatures simultaneously, you'll need to work in batches.
Flaws but not dealbreakers: Small food items fall through the grates, and there's no preheat feature, so you wait for the temperature to climb. Neither is a dealbreaker, but they're worth knowing.
This is for the person who wants one simple, reliable machine that just works.
Upgrade pick: The Ninja Foodi Smart XL Grill
This is the one that does everything. It's an indoor grill, an air fryer, a roaster, a dehydrator, and a bake oven all in one. I've used the grill function for steaks that sear with actual grill marks, and the air fry function for frozen fries that came out crispy in 12 minutes. The Smart XL name is earned, the cooking space is generous, and the non-stick surface releases food without a fight.

Here's the thing though, the air fry function is the weakest of the three. The fan is less aggressive than the dedicated air fryers, so the crisp factor is a notch below. My chicken thigh test came out cooked through but the skin wasn't as crackling as the DZ401. It's a tradeoff for the versatility.
The smart thermometer is genuinely useful. I set the target temp for chicken, and it beeps when it hits 165. No guessing, no pink at the bone. I've used it for a whole roast chicken that came out juicy and golden.
Flaws but not dealbreakers: It's not as good at air frying as the dedicated machines, and it's an investment at ~$179. But if you don't have a grill and want to replace two appliances with one, it's worth it.
This is for the person who wants an air fryer and a grill but only has room for one machine.
Budget pick: The Ninja Crispi Pro Glass
I was skeptical about a glass air fryer, but the see-through basket is genuinely useful. I can check on my food without pulling the basket out and losing heat, which means less flipping and more even cooking. The 6-in-1 functions cover everything I need, and the Cyberspace color is a nice change from the usual black and silver.

The even browning is the highlight. The cake test came out with no hot spots, and the frozen fry test produced crispy, golden fries in 11 minutes. It's also noticeably quieter than the original Ninja models, which is a big deal for me.
The glass feels fragile though. I'm careful with it, but I'm not sure it would survive a drop the way a stainless steel machine would. And the usable footprint is smaller than the advertised size, so I measured it and found it holds about 3.5 quarts of actual cooking space.
Flaws but not dealbreakers: The glass is a concern if you're clumsy, and the capacity is smaller than the spec sheet suggests. But the visibility is a real advantage.
This is for the person who likes to watch their food cook and doesn't mind being gentle with their appliances.
The competition
The Ninja French Door Air Fry Oven is a toaster-oven style, and I've said it before, drawer style is superior. Mine burned everything, and I've heard that complaint echoed in dozens of reviews. The 20.3-quart capacity is impressive on paper, but the interior is cramped and the heat distribution is uneven. Skip it.
The Ninja Crispi Glass 4-in-1 is the smaller sibling of the Crispi Pro, and it's fine, but the lack of a preheat feature and the smaller capacity made it a non-starter for me. The Air Fryer Pro 5 Qt does more for the same price.
The Foodi Smart XL Grill is a great machine, but if air frying is your primary goal, the DZ401 is better at it. The grill is for people who want to replace multiple appliances, not for people who want the best air fryer.
The bottom line
I've cooked in every one of these machines for a month straight, and the DZ401 DualZone is the one I'd buy again. It's quiet, it cooks evenly, and the two baskets changed how I meal prep. The Air Fryer Pro 5 Qt is the best value for smaller households, and the Foodi Smart XL Grill is worth it if you want to replace your grill and your air fryer in one shot.
Spend the ~$11 for the magnetic strips that hold paper liners in place, otherwise they slide around. And do not put a paper liner in the basket during preheat.
God Bless the person who invented this thing, and let your food-freak flag fly.
