How we tested each Air Fryer

To get the best and most comprehensive results from each air fryer, we tested them with a variety of different foods. This includes well-seasoned chicken wings, white sandwich bread, spring vegetables such as zucchinis and carrots and even frozen fries. Though the size and quantity that each air fryer holds are significantly different, we packed the baskets in keeping with the instructions from the manufacturer, to make sure we could get a clear view of how both appliances performed. Where there was any uneven browning, crispiness, or food left uncooked, we were able to see both the effectiveness and inefficiencies of each machine.

For lighter products that are quite easy to cook, such as the white sandwich bread and spring vegetables, both air fryers performed pretty well, and quite similarly. We did realise that even though the Instant Pot held more, the square basket in the Cosori allowed us to pile the foods right on top. Ultimately, the foods both cooked well, with the toast having that nice buttery glaze.

Next, we tried foods that took a little more elbow grease, such as chicken wings and frozen fries, where both brands still gave similar results. When we cooked the frozen fries in the Cosori air fryer, they were done in a couple of minutes, even though they were frozen. There were a few in the middle that were not as crispy as those from the outer corners, but overall it was a good result. The Instant Pot Duo did a slightly better job though, cooking the fries completely through. When it came to the chicken wings, both air fryers worked well, but we found that the chicken wings from the Instant Pot Duo were just a little more tender than the ones from Cosori. For the Cosori air fryer, we placed the chicken wings on the snowflake option to see if it would cook thoroughly, and it did, but maybe a different option would’ve given a more tender result.

Key Differences between the two air fryers

There are quite a number of differences between both products, and to help you decide, we’ve compiled this list of the major differences that will help you decide which is the best for you to purchase.


Cosori’s air fryer is made with appearance and functionality in mind, and you can tell by looking at it.  With its sleek coating and modern design, it’s no wonder why they are so popular. In keeping with the standards for electronics to be aesthetically pleasing, Cosori has created the ideal product with an easy-grip handle, and a removable basket for improved efficiency.

With its petite size, it looks just as quaint sitting next to your coffeemaker on the kitchen counter.  The Instant Pot Duo has also kept up with a sleek innovative design, as it boasts an elegant silver finish with a black, rubber cover. Unlike many other air fryers on the market, they do not have a traditional pod shape but are more pot-like. The Instant Pot Duo is also larger than the Cosori air fryer, which may cause it to lose some points for effective storage and limited efficiency. Both air fryers are designed with a modern feel to fit the needs of the modern man and woman, and depending on your space, you can determine which is best for you.

Some of its most popular functions include defrosting, preheating, air frying, cooking, warming and toasting, among other functionalities.

The Instant Pot Duo air fryer has comparable functionality, with its own 11-in 1 multifunctionality. One unique feature that makes it stand out though is its ability to pressure cook, which is not a function that is not foundational to most air fryers. Still, both products boast all the modern functionalities needed for a quick and easy dinner, with a high-quality performance as well. We have also evaluated how loud both air fryers get when operating.

A quick look at the Amazon reviews for each product shows that both products rank highly and within a similar percentage. 94% of people who bought the Instant Pot Duo air fryer had a positive experience, while 93% of those who bought the Cosori air fryer had a positive experience.

Manufacturing and place of Origin

The origins of the Cosori air fryer are quite hard to find, but after doing some digging, we think we’ve figured it out. This company is linked to the United States, Canada and China, with its true origin remaining a mystery. While the company name is officially trademarked in Canada, the products are designed in the United States and are manufactured in China.

For the Instant Pot Duo air fryer, the origins and manufacturing are pretty similar, minus the inclusion of the United States. This company came into operation after four telecommunications employees decided to band together and create designs for what is now known as the Instant Pot brand. The brand’s official owner, Robert Wang, created the product and brand in 20009, in Ottawa Canada. New designs still come from the Canadian based quartet, but the Instant Pot Duo is actually manufactured in China.


Cosori’s premium air fryer boasts a 5.8-quart (5.5 litres) detachable basket, which is a great size for family-sized meals, without taking up too much space on your counter. The fact that the basket has square edges instead of rounded ones, allows you to get the full use which makes it feel larger than it is. This is unique to Cosori, though more and more brands are beginning to adopt this design.

The Instant Pot Duo air fryer is quite larger, with an 8-quart interior space that comes with a removable basket as well. With their larger size, they can be a bit inconvenient but this all depends on what you’re looking for.


Manufactured in China, the Cosori air fryer looks well made and ready to be used. Perhaps the most popular question we get about the material and construction of the materials that make up this air fryer is whether or not they have a non-stick basket, and we’re happy to report that they do! This is great as it helps with an easy clean up after you finish cooking.

The Instant Pot Duo presents a stainless steel alternative to the non-stick option that the Cosori has, for those who prefer stainless steel.  Be careful though, as at least one piece of the coating of the basket is coated with Teflon/ PTFE, which can be toxic to some animals such as birds.

Ease of use

Cooking constantly is one thing, but the clean up is another. Cosori’s air fryer presents an easy-to-use, appliance alternative to the millions of pots and pans that we would normally use to prepare one meal. And the flip side is that this also makes clean up so easy too! The biggest issue we had with this air fryer was the annoying beeping sound that you hear when you plug it in to cook. For a modern air fryer, we didn’t expect that sound, especially when most other modern competitors don’t have it. So how does the Instant Pot Duo air fryer compare?

The Instant Pot Duo is also great when it comes to ease of use. Apart from having just one product to clean, similarly to Cosori’s air fryer, the Instant Pot Duo also makes clean up easy. The only thing we’re not used to is the heavy lid, as most air fryers just require you to remove and replace the basket. The lid is necessary though, for the pressure cooking feature on the air fryer to work. Ultimately, both air fryers are very convenient and easy to use, but just be mindful that the Instant Pot Duo has a heavier lid that has the potential to become annoying with consistent use.


Do we ever really consider warranties when it comes to appliances anymore? Yes? Okay. The Cosori air fryer boasts a 1-year warranty for customers who want to ensure that they get their money’s worth. If you abide by the instructions in the manufacturer’s guide but have an issue with your air fryer before this time is up, then you’re eligible for a replacement under their warranty.

You also have the option of adding a year to your warranty package but you have to register your product with the Cosori team. The Instant Pot Duo air fryer also boasts a warranty period that lasts up to one year after purchase. They do not give you the option to extend your warranty like Cosori, but this is also pretty common for companies who manufacture kitchen appliances.


Now this is where things get a little interesting. Even though the Cosori air fryer is the national bestseller in the US, it retails at a significantly lesser amount than the Instant Pot Duo air fryer. This may be due to size though, as the larger air fryers do tend to retail for a higher cost. In this instance, the Cosori air fryer retails for $119.99, while the Instant Pot Duo air fryer retails for about $199.99.

This may also be based on the fact that Instant Pot is also a revered brand that has a loyal customer base, who tend to support whatever products they make. Lastly, this may also be because their air fryers do have a pressure cooker feature, which is not common in the air fryer/ appliances space.

Downsides Detected

While both the Cosori and Instant Pot duo air fryers are regarded so highly as two of the best on the market, some downsides have been detected with each, that you need to know about before purchasing your new air fryer. Here is a list of some of the major downsides that have been detected in both.

  • The plastic-y smell when cooking (in both products) – Even though the Instant Pot Duo air fryer has traded in the traditional PTFE coating for stainless steel, they still have the same issues as Cosori when reviewed. Some customers report having experienced a terrible smell of plastic burning after about 10 minutes of using these air fryers, but we didn’t notice this during any of our testings for each air fryer.It is possible that this could have been a manufacturing fault in a few of the designs of these products, but these downsides have only been experienced by a few customers, according to Amazon.
  • Product leaks steam after long-term use – For the Cosori air fryer specifically, there have been reports of leaking when used for an extended period. One reviewer reported seeing puddles on her kitchen counter after cooking every time and has reported it to the company’s support team who told her this was normal.What’s funny though is that once she pressed lightly on the basket, she was able to stop this leaking, leading us to believe this is a possible defect that is unique to the Cosori air fryers, and that you may experience as well.
  • Short shelf-life, despite 1-year warranty – It would appear that both the team at Cosori and Instant Pot Duo know that some of their products just randomly stop working in early stages, which is why the warranty lasts for up to a year.There have been instances where the Cosori air fryer caught on fire in less than a year of use or broke down in less than 6 months. There have also been instances where customers have received defective baskets, with handles that break off easily.

Instant Pot duo has also had issues with longevity, with the material of its product remaining as durable as promised. Customers have reported rusting within a week of consistent use, annoying messages of burning when the food isn’t even finished cooking, and a host of other special issues.

Other air-frying Options

If the possibility of experiencing any of the downsides listed above makes you want to look at other options, then we’ve got you covered. There are other options for air fryers that are as highly revered and work just as effectively as both the Cosori air fryer and the Instant Pot Duo. One of the most popular, best-selling options is the Ninja Air Fryer Max XL, which is a 5.5-quart basket style air fryer that has a 7 in 1 multi-use capability. It cooks food with up to 450 degrees of superheated air, leading to faster cooking times than the Cosori and the Instant Pot Duo.  Even though it cooks faster, the Ninja Air Fryer Max XL is a healthier alternative, as it cooks with up to 75% less fat than most air fryers on the market.

We’ve also looked at the Philips Compact Air Fryer because of its popularity and the fact that it has been named a great alternative. Similarly to the Ninja Air Fryer, the Philips air fryer cooks your food with less fat than traditional brands including Cosori and Instant Pot Duo, but their technology is a little bit different. The Philips Compact air fryer uses fat removal technology to extract excess fat, which it stores below, for a healthier air frying option. With its sleek design, classic pod shape and easy to use interface, it rivals both the Cosori and Instant Pot Duo air fryers. The only thing you need to watch out for though is the price, as it seems that the price of both these products, directly reflects their functionality.

FAQs about both air fryers

  1. What’s in the box? – Both air fryers come with different makeups. For the Cosori air fryer, the box contains a 5.8-quart air fryer, a recipe book, a user manual and a quick reference guide. For the instant Pot Duo, the box includes an electric pressure cooker and air fryer, a protective pad and storage cover, a multi-functional rack and a quick user manual.
  2. Is the Cosori Air Fryer quiet? It depends on what you call quiet, but both air fryers have minimal sound when plugged in and working. Hearing any strange sounds from your air fryers would be a cause for concern.
  3. Is the Teflon/ PTFE harmful? – The Teflon in both air fryers is simply to prevent excessive sticking to the pan which can ruin the ingredients even more.e They are safe for use, but if you’ve been smelling, you’re likely overheating your pan. Overheating your Teflon/ PTFE coated air fryer can cause the PTFE to release chemicals and gases that can cause you to have a headache or fever.

Final Thoughts

Both the Cosori and Instant Pot Duo air fryers are appropriately priced, well manufactured and easily accessible, which are all great for anyone wanting to purchase an air fryer. Pay close attention though, to the difference in sizing and design, to help you decide which of the two is best for you, and your lifestyle.Deciding to get an air fryer can be a difficult task, but we hope that this review will help you to make an informed decision and choose the best option for you.
