Is the Swan 11L Duo Layer Air Fryer worth the hype? An honest review
Air fryers have completely changed how I cook dinner. Like many of you, I jumped on the bandwagon a while ago and never looked back. But with so many options now available, it is hard to know which one is actually worth your money.
I recently got my hands on the Swan 11L Duo Layer Air Fryer. It promises a massive capacity without taking up all your worktop space. The design is clever because it stacks the baskets on top of each other rather than side-by-side. This sounded perfect for my kitchen full of gadgets, but I wanted to see if it lived up to the claims.
I have been testing this machine thoroughly. In this Swan Twin Stack Air Fryer review, I will share exactly what I found. I will cover everything from how easy it is to use to how well it actually cooks your food. I will also tell you if I think the Swan 11L Duo Layer Air Fryer is worth the £99.99 price tag.

Why trust my review?
I’ve used air fryers for several years and cook most family meals from scratch. Before buying the Swan 11L Duo Layer Air Fryer, I had experience with both single-drawer and dual-drawer models, so I was particularly interested in whether the unusual stacked design would genuinely save space without compromising cooking performance.
Over several weeks I used it for everything from homemade chips and jacket potatoes to frozen foods, leftovers and family meals. This review is based on my own experience rather than simply repeating the manufacturer’s claims.
First impressions and design
When I first unboxed the Swan 11L Duo Layer Air Fryer, the first thing I noticed was the shape. Most dual air fryers are very wide and take up a huge chunk of the counter. This one is different. It is taller and narrower because the baskets are stacked whilst still being a large capacity air fryer.
It measures 35.2cm high, 44.5cm wide, and 27.9cm deep. While it is still a big appliance, the footprint feels much more manageable than other 11-litre models I have seen.
The build quality feels decent. It is mostly black plastic, which is standard for air fryers these days. It looks modern and sleek. The baskets have viewing windows, which I love. Being able to see your food cooking without opening the drawer and letting heat escape is a really useful feature. If you are looking for an air fryer with viewing window then this is definitely one to consider.
One thing that stood out was the control panel. It is a touch screen that folds back. This is a nice touch for storage.
Capacity and baskets
The total capacity is 11 litres, split between two 5.5-litre baskets. This is a lot of space. Swan claims you can cook a whole chicken in each drawer. I haven’t tried, but it seems likely.
Because you have two separate drawers, you can cook different things at the same time. I tried cooking a main dish in one and a side dish in the other. It is great for feeding a family or for meal prepping for the week.
The baskets come with grill plates that you can take out for cleaning. The non-stick coating seems to work well so far. Food slides right off, and they wash up easily with hot, soapy water.
One minor gripe is that the stacked design can make it a bit tricky to check the bottom basket if you have the top one open. You have to be careful not to knock anything. But overall, the space-saving design in the Swan 11L Duo Layer Air Fryer is a winner for me.
Cooking performance
This is the most essential part. Does the Swan 11L Duo Layer Air Fryer actually cook food well? The short answer is yes, but with a few caveats.
I started with the classic air fryer test: homemade chips. I used the preset function for fries. The results were good. The chips came out crispy on the outside and fluffy on the inside. I did give the basket a good shake halfway through, which the machine reminds you to do with a beep.
I have also tried things like frozen onion rings, reheating pizza and crisping jacket potatoes.
However, I did notice a slight difference in cooking speed between the two drawers of the Swan 11L Duo Layer Air Fryer. The top drawer seemed to cook slightly faster than the bottom one. This might be due to how the heat circulates. It is not a deal-breaker, but something to keep in mind. You might need to add an extra minute or two for food in the bottom basket.
I also found that the temperature controls took some getting used to. You have to be precise with the touch screen. Sometimes it felt a bit unresponsive, and I had to press a few times to get it to register.
Swan claims their “Cyclone Technology” used in the Swan 11L Duo Layer Air Fryer saves up to 67% on energy compared to a conventional oven. While I cannot measure the exact percentage in my kitchen, it definitely cooked faster than my big electric oven. The National Energy Foundation states that air fryers generally consume less electricity due to their smaller size and convection fans, so the savings are real.

Features and functions
The Swan 11L Duo Layer Air Fryer comes with 10 preset functions. These include settings for fries, chicken, steak, and fish. I found the presets to be a good starting point, but I often adjusted the time and temperature manually to suit my taste.
There are two standout features on this model:
- Sync Finish: This ensures that both baskets finish cooking at the exact same time. This is brilliant if you are cooking meat in one drawer and veggies in the other. No more cold side dishes while you wait for the other dish to finish.
- Dual Cook: This matches the settings for both baskets. If you are cooking a huge batch of chips across both drawers, you just set it once and hit this button.
The temperature range goes from 60°C to 200°C. This is standard for most air fryers. It is hot enough to crisp up bacon but low enough to gently reheat leftovers.
The Swan 11L Duo Layer Air Fryer timer goes up to 60 minutes. This is plenty for most meals. If you are slow-cooking something, you might need to reset it, but for day-to-day cooking, it is fine.
What I would like to see improved
After using the air fryer regularly, there are a few things I think could be better:
- The touch screen can occasionally need a second press.
- The lower drawer sometimes takes slightly longer to cook.
- The instruction booklet could include more realistic cooking times.
- Because of the stacked design, checking the lower drawer isn’t quite as convenient as a traditional side-by-side model.
None of these are deal-breakers for me, but they are worth knowing before you buy.
Does the Swan 11L Duo Layer Air Fryer save money?
Like most air fryers, the Swan heats up much faster than a conventional oven and cooks in a smaller space.
Swan claims energy savings of up to 67% compared to a conventional oven. While I couldn’t verify the exact figure at home, I definitely noticed shorter cooking times and less need to switch on the main oven for everyday meals.
Safety and cleaning
Safety is always a priority in the kitchen. The Swan 11L Duo Layer Air Fryer has an auto-shutoff function, which gives me peace of mind. It turns off if you pull the basket out.
The outside of the unit does get warm while cooking, but not dangerously hot. Just make sure you leave enough space around it for air to circulate. My guide to your first air fryer will help with that.
Cleaning is straightforward. The baskets and grill plates are not listed as dishwasher safe in the manual I saw, so I stuck to hand washing. The non-stick coating makes this easy. A quick wipe with a sponge usually does the trick. I would recommend avoiding harsh scourers so you do not damage the coating.
It is important to ensure food is cooked safely. When cooking poultry like chicken or turkey, the Food Standards Agency advises that the food should be steaming hot and cooked all the way through, with no pink meat. The core temperature should reach 70°C for 2 minutes. I used a meat thermometer to be sure, and the Swan 11L Duo Layer Air Fryer hit these temperatures reliably.

The pros and cons
To help you decide, here is a quick summary of what I liked and did not like about the Swan 11L Duo Layer Air Fryer.
Pros:
- Space-saving design: The stacked baskets are great for smaller kitchens.
- Large capacity: 11 litres is enough to feed a large family.
- Viewing windows: You can check your food without losing heat.
- Sync function: Everything is ready at the same time.
- Good value: At under £100, it is cheaper than many other dual air fryers.
Cons:
- Touch screen: It can be a bit dim and sometimes unresponsive, but after a few presses, it works fine.
- Uneven cooking: The top drawer seems to cook slightly faster than the bottom.
- Bulky: Even though it saves width, it is quite tall and deep.
- Instruction manual: It is a bit basic and could be clearer on cooking times for each of the preprogrammed options.
Who should buy the Swan 11L Duo Layer Air Fryer?
After using it regularly, I’d say this air fryer is ideal for:
- Families of 4 to 8 people
- Anyone with limited worktop space
- People replacing an older single-drawer air fryer
- Those wanting to cook complete meals at once
- Anyone looking for a large-capacity air fryer without spending Ninja prices
However, if you mostly cook for one person, the capacity may be more than you need.
Swan 11L Duo Layer Air Fryer vs Ninja Dual Zone
Many shoppers considering the Swan are also looking at Ninja models as they are both popular choices for a vertical stack air fryer. Here is a simple Swan vs Ninja air fryer comparison if you are considering both, that may help you. Both feature frequently is lists of the best air fryer for families and it is easy to see why.
| Feature | Swan 11L Duo Layer | Ninja Dual Zone |
|---|---|---|
| Capacity | 11L | Usually 7.6L to 9.5L |
| Design | Vertical stack | Side-by-side drawers |
| Worktop space | Smaller footprint | Wider footprint |
| Price | Budget-friendly | Premium |
| Viewing windows | Yes | Depends on model |
In my opinion, the biggest advantage of the Swan is the space-saving design. The biggest advantage of the Ninja is the more premium feel and generally more consistent cooking results.
My Swan Twin Stack Air Fryer review
After using the Swan 11L Duo Layer Air Fryer for a few weeks, I am impressed. It is not perfect, but for the price, it offers many features.
The stacked design is a clever solution for anyone short on counter space. The capacity is fantastic, and the cooking results are generally very good once you get the hang of the timings.
If you are looking for a high-end air fryer with a premium feel, you might want to spend a bit more on a brand like Ninja. But if you want a solid, family-sized air fryer that does the job well without costing a fortune, this Swan 11L Duo Layer Air Fryer is a great choice. It has earned a permanent spot on my kitchen counter.
