In the cosori vs typhur comparison, Consumer Reports measured just 4.5 quarts of capacity in the Cosori TurboBlaze CAF-DC601-KUS — the widest gap of any fryer here. Cosori sells it as 6 quarts. That is the widest gap of the four machines on this page, but it is not the only one. The Instant Pot Vortex Plus 6QT (140-3089-01) measured 5.2 against an advertised 6. The Ninja DoubleStack XL SL401 measured 9 against an advertised 10, and the Typhur Dome 2 AF03 measured 5 against an advertised 5.6. Every one came in under. Only Typhur publishes a usable cooking area on its own spec sheet. It is also the most expensive machine here, by a factor of nearly three.
After years of buying ordinary kitchen gear, I have learned the number on the box and the number you get rarely match. So a machine that measures short of its advertised capacity doesn’t surprise me. It just tells me which brand rounds up the most.
Updated August 31, 2026: capacities re-verified against Consumer Reports’ measured figures for all four machines. Every price traces to each maker’s own current listing — Typhur’s Dome 2 lists at $339.99. Added the February 2023 Cosori recall and its twenty-one model numbers, none of which is the TurboBlaze.

Cosori’s 6-Quart Basket Measured 4.5 Quarts in Consumer Reports’ Test
Consumer Reports measured just 4.5 quarts inside the Cosori TurboBlaze CAF-DC601-KUS, which Cosori sells as a 6-quart basket. They are also the number nothing forces a maker to define. A basket’s raw volume, measured to the rim, is not the volume you can cook in. No US rule says which of the two goes on the box.
Consumer Reports publishes both a Claimed capacity field and a Measured Capacity field on its air fryer pages. On all four of these machines the claimed field is blank. The unit “qt.” prints with no numeral in front of it. The measured field is filled in on all four. So the comparison below is mine. It sets Consumer Reports’ measured figure against the number each maker prints on its own product page, which I read on the same day.
| Machine | What the maker prints | Consumer Reports measured | Short by | Measured share of advertised |
|---|---|---|---|---|
| Cosori TurboBlaze CAF-DC601-KUS | “6 qt / 5.7 L (serves 3–5 people)” | 4.5 qt. | 1.5 qt | 75.0% |
| Instant Pot Vortex Plus 6QT 140-3089-01 | “6.0 Quart” | 5.2 qt. | 0.8 qt | 86.7% |
| Ninja DoubleStack XL SL401 | “10 QT capacity lets you cook two, 5-lb chickens at once” | 9 qt. | 1 qt | 90.0% |
| Typhur Dome 2 AF03 | “5.6 qt” | 5 qt. | 0.6 qt | 89.3% |
Verdict on the claim: all four advertised figures are higher than what an independent lab measured. Cosori’s is the one that changes a buying decision. Three quarters of the advertised number is a real difference. It’s the gap between a fryer that holds dinner for four and one that holds dinner for three.
How Much Do These Air Fryers Fall Short of Their Advertised Capacity?
Across all four machines, the measured shortfall runs from 0.6 quarts on the Typhur to 1.5 quarts on the Cosori, below each one's advertised capacity. A rim-full measurement is a real measurement. It is just not the one you cook with. Every maker gets to pick which one it prints.
What none of the four publishes is a maximum fill line. I read Cosori’s manual for the TurboBlaze and Typhur’s manual for the Dome 2. Cosori’s says food that touches the heating coils is a fire hazard and tells you not to overfill. Typhur’s says not to exceed “the maximum level indicated in the basket.” That’s a mark moulded into the plastic, with no number attached to it anywhere in the document. Instant’s manual for the 140-3089-01 carries the same generic instruction and no figure.
So the honest position is that the usable number is not published by anyone selling these machines. It exists in one place, and that place is a lab you have to pay to read.
Typhur Dome 2: 139.5 Square Inches Under a 2.3-Inch Ceiling
Typhur is the only maker that publishes a usable cooking area. That area is 139.5 square inches under a 2.3-inch ceiling. Typhur prints “Cooking Area: 139.5 sq in” and “Basket Height: 2.3″” directly on the Dome 2’s spec table. Those two numbers tell you more about what fits than 5.6 quarts does. That’s because an air fryer cooks in a layer, not a volume.
For the Cosori, the equivalent figure comes from outside. TechGearLab lists a measured cooking area of 85.6 square inches for the TurboBlaze. Typhur’s published area is 1.63 times that. Ninja and Instant publish no area figure at all. I could not find an independently measured one for either, so those two cells stay empty rather than get filled with a guess.
Ninja does publish a food-weight claim instead: “10 QT capacity lets you cook two, 5-lb chickens at once.” That’s one chicken per drawer. It is a more useful sentence than a quart figure. It is also the only one of its kind on any of these four pages.
Cosori vs Typhur: Which Air Fryer Buys the Cheapest Volume?
The Ninja DoubleStack XL buys the cheapest volume at $24.44 per measured quart. That’s once price is divided by measured capacity instead of the advertised one. Prices below are what each maker’s own store displayed on August 31, 2026.
| Rank | Machine | Maker’s own price | Measured quarts | Dollars per measured quart |
|---|---|---|---|---|
| 1 | Ninja DoubleStack XL SL401 | $219.99 (from $249.99) | 9 | $24.44 |
| 2 | Cosori TurboBlaze | $119.99 | 4.5 | $26.66 |
| 3 | Typhur Dome 2 | $339.99 (from $399.99) | 5 | $68.00 |
| — | Instant Pot Vortex Plus 6QT | no price rendered | 5.2 | not computed |
The Typhur costs 2.78 times what the Ninja costs per measured quart. That is not an argument against it. A wide shallow layer under two elements is a different machine from a deep drawer, and 139.5 square inches of single-layer space is the thing you are paying for. It is an argument against buying it for capacity.
Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
Instant Vortex Plus’s Price Doesn’t Render on Instant’s Page
The Instant Vortex Plus is missing from that ranking. Its current price could not be read from Instant's own product page. That page, for the 140-3089-01, publishes the capacity (“6.0 Quart”) and the wattage (“1700 watts, 120 V~ 60 Hz”). It renders no price numeral at all. The price loads in the browser afterwards.
That is a narrower claim than “Instant publishes no price.” It publishes one. I could not retrieve it from the page. I am also not going to substitute a retailer’s number for a maker’s and then rank on it. The cell stays empty, and the ledger below charges Instant for it. A price you cannot read is a price you cannot compare.
Cosori’s February 2023 Recall Covered Twenty-One Model Numbers
On February 23, 2023 the Consumer Product Safety Commission announced a recall of about 2 million Cosori air fryers, with a further 250,000 in Canada and 21,000 in Mexico. The hazard: “A wire connection in the air fryers can overheat, posing fire and burn hazards.” The CPSC notice records 205 reports of air fryers catching fire, burning, melting, overheating and smoking, including 10 reports of minor superficial burn injuries and 23 of minor property damage.
Twenty-one model numbers are named. They are CP158, CP137, CS158, CO137, CO158, CP258 and CAF-P581 variants. CAF-DC601-KUS — the TurboBlaze — is not among them, and the recall predates the line. I am telling you this because a two-million-unit fire recall on a brand is worth knowing before you buy that brand. It’s not because this machine is subject to it. Instant Brands’ only CPSC recall I could find is a 2015 pressure cooker action. I found no CPSC air fryer recall for SharkNinja or for Typhur.
Cosori vs Typhur: Which Air Fryer Wins on the Scorecard?
On a five-axis weighted scorecard, the Ninja DoubleStack XL edges out the Cosori TurboBlaze, 79.8 to 78.5. The Typhur Dome 2 sits at 66.8, and the Instant Pot Vortex Plus is last at 36.8.
These four air fryers were scored across five weighted axes. Capacity carries the heaviest weight, because it is the thing every one of these is sold on and the thing all four overstate. Price per measured quart comes second, because it is the only price comparison here that survives contact with the measurements. The three 15% axes are disclosure axes: what the maker tells you before you pay.
| Axis (weight) | Ninja SL401 | Cosori TurboBlaze | Typhur Dome 2 | Instant Vortex Plus |
|---|---|---|---|---|
| Usable capacity you can verify (30%) | 75 | 40 | 95 | 65 |
| Dollars per measured quart (25%) | 100 | 92 | 36 | 0 |
| Warranty as written (15%) | 50 | 100 | 65 | 50 |
| Speed claim with a named baseline (15%) | 70 | 90 | 35 | 45 |
| Price and stock on the maker’s store (15%) | 95 | 100 | 95 | 20 |
| Weighted tally | 79.8 | 78.5 | 66.8 | 36.8 |
Cosori vs Typhur: How Is Each Axis Scored?
Three of those axes need their scoring explained. Warranty: Cosori gives two years. Typhur gives one that stretches to eighteen months if you register within 30 days. Ninja and Instant give one. Speed claims: Cosori’s US page says “cooks meals up to 46% faster*” and the asterisk names the comparator — “COSORI’s CP168 (or Pro Gen 2) air fryer.” A named baseline is rare, and it scores well. Typhur’s “up to 30%” is against “conventional models,” which is not a comparator. Instant’s “50% faster” is against deep frying and a conventional oven, a category rather than a machine. Ninja’s US page made no speed claim I could find. That’s why it scores above the two vague ones: a claim not made cannot mislead.
Disagree with a weight? Move it. Push capacity to 45% and the Typhur closes on the leaders. Push price per measured quart to 40% and the Ninja walks away with it. That is the point of showing the arithmetic.
Cosori vs Typhur: Which Air Fryer Is Wrong for Your Kitchen?
Skip the Ninja DoubleStack XL if you cook one thing at a time. Nine measured quarts split across two stacked drawers is not one big basket. Each drawer is also shallower than a standard 6-quart. Its whole case is two dishes finishing together.
Skip the Cosori TurboBlaze if you are buying on the quart figure. It is the best-value single basket here. It is also the machine with the largest gap between the box and the lab. At 4.5 measured quarts, it is a two-to-three-person fryer wearing a three-to-five-person label.
Skip the Typhur Dome 2 if your reason is volume. $68 a measured quart is 2.78 times the Ninja’s rate. Buy it for the 139.5-square-inch single layer and the 12-inch pizza that fits in it, or don’t buy it.
Skip the Instant Pot Vortex Plus if you want to price it before you shop. It is the named loser here at 36.8. Most of that deficit is disclosure rather than hardware: 5.2 measured quarts is the second-best result on this page, on a machine whose own store would not show me what it costs.
Ninja vs Cosori: 1.3 Points Apart on the Scorecard
After watching kitchen gear fail right when the warranty ends, the Cosori TurboBlaze is the one I would point a friend to, because two years of coverage beats a bigger drawer. The Ninja and the Cosori finish 1.3 points apart. That’s 79.8 to 78.5 — effectively a tie on the final tally. The tally will not settle it, so I will.
I would spend my own $119.99 on the Cosori TurboBlaze. Two years of warranty against one, a named baseline behind its speed claim, and a hundred dollars kept. The Ninja wins on dollars per measured quart because it is a bigger machine. If you are actually feeding four people twice a week, that is the right trade. If you are two people, you are paying $100 more for a second drawer. You’d also have a taller footprint to measure against your cabinets first.
One more thing, since you are trusting my arithmetic. Every capacity figure above is a single lab’s measurement of a single unit. Consumer Reports does not publish its fill protocol on these pages. I also have no second lab to check it against. That is a real limit on the four numbers this whole comparison rests on, and you should know it before you use them.
Already sold on the category and want the machine, not the audit? Our five-axis ledger on five current air fryers scores the field on cooking performance instead. The same advertised-versus-usable problem turns up one appliance over in electric pressure cookers, where Breville’s own manual caps a 6-quart at 4.5, and if you are still deciding between appliance categories, start with the countertop oven comparison.
