Cosori Dual Air Fryer Review UK 2026
Quick verdict
Score: 9.0/10
Best for: Faster, lower-oil everyday cooking and reheating
Not for: Large family roasts and big-batch cooking, where a full-size oven still wins on capacity
Bottom line: A practical air fryer (8.5L, 8 functions) that crisps food fast with little oil and costs less to run than an oven.
The Cosori Dual Air Fryer is a practical option for bigger households, mainly because it offers an 8.5L family-size capacity and includes 8 cooking functions. It suits cooks who want one appliance for tasks like air frying, roasting, and baking, without juggling separate tools. It also supports the brand's split-pan concept, which can help when timing two foods, though results still depend on ingredient size and placement. This air fryer can feel bulky on smaller counters, and the learning curve may take a few trial batches. Overall, it is versatile, but not effortless.

Capacity and Size
An 8.5L family-size capacity gives the Cosori enough room for batch cooking, with two compartments that can be used at the same time or separately. Each side supports cooking two items at once, which helps reduce meal prep time. The dual-basket approach also allows mixed schedules, for example, cooking one dish first and finishing the other. For households with larger portions, this capacity is practical, although 8.5L may feel limiting for very large joints or multiple sides. Actual usable volume depends on food shape and basket fill level.
Cooking Performance and Functions
Cooking performance is where this dual-basket design shows its value, because it is built for two tasks at a time while keeping separate control for each side. It is described as an 8-in-1 double airfryer, with Air Fry, Roast, and Bake as named functions. The remaining modes are Sync Cook & Finish and Fast and Energy Save, plus Healthy 50+ online recipes for guidance. In day-to-day use, both baskets can be loaded with different foods and run independently, with results depending on how evenly items are sized.
Single or Dual Zone
How flexible is the air fryer setup for single-drawer cooking versus a truly dual-zone layout? The Cosori is presented as a double unit, but the provided details do not specify the degree of independent control between the two sides. In a dual-style basket arrangement, two items are typically cooked at the same time, for example roasting vegetables on one side while cooking chips on the other. If both sides share airflow and timing, results can be limited by whichever recipe takes longer. Where independent settings are available, batch cooking is more straightforward because different temperatures or times can be matched to each dish.
Ease of Use and Controls
Despite being designed for family-size batches, ease of use depends on how consistently both sides are set up and operated, as the provided details do not specify whether the controls are fully independent per drawer. The air fryer offers 8 cooking functions, including Air Fry, Roast, and Bake, plus Sync Cook & Finish for coordinating two foods. The 8.5L family size suits batch cooking, and double-zone use may require attention to align doneness between the two sides. The paired accessories can simplify kitchen workflow.
Cleaning and Maintenance
Cleaning and maintenance are mainly about keeping the dual drawers, trays and included accessories free of grease. Performance depends on how soon items are handled after cooking. After meals, unplug the unit and allow it to cool before wiping the non-stick surfaces with a damp cloth. Remove the trays and accessories carefully, then wash them by hand or in warm, soapy water in the sink. Stubborn residue may require soaking, but abrasive pads should be avoided to protect the coatings. Do not let water enter the main unit. Clean the exterior last using a lightly damp cloth.
Noise and Energy Use
After addressing how to keep the drawers, trays, and accessories free of grease, it also helps to understand what this type of appliance is like during operation, especially in shared homes. Air frying works by circulating hot air, so running cycles continue until food reaches doneness, and steam may produce a soft hiss. For energy use, the listing only states "Fast and Energy Save", without wattage or cost. A practical approach is to preheat briefly if needed, avoid opening the drawers often, and use the 8.5L capacity efficiently.
Who Is This Air Fryer For?
Who would likely benefit most from the air fryer is easiest to judge by looking at daily meal routines and kitchen space needs. It suits larger households or anyone cooking multiple portions, thanks to an 8.5L family size and 8 cooking functions. People who like planning ahead may appreciate Sync Cook & Finish, which helps coordinate cooking times. It also fits users who value simple presets such as air fry, roast, and bake, plus Sync Cook & Finish. Those wanting a compact countertop appliance may find the dual, larger footprint awkward. It suits regular home cooks, not those needing occasional snacks only.
Where to Buy in the UK
Several UK retailers may carry the Cosori Dual Air Fryer. The most reliable approach is to check multiple listings, as availability and bundle contents can change. Shoppers typically find it on major online marketplaces, home appliance websites, and sometimes retailer direct stores, and they should confirm the exact model details before ordering, including the 8.5L family size, 8-in-1 double airfryer functions, and the included 5 accessories. If a listing is sold as "air fryer only", fewer extras are included. Delivery timing can vary by postcode, so returns and delivery-day estimates should be checked for the chosen retailer.
Frequently Asked Questions
Is the Cosori worth it?
For faster, lower-oil cooking of chips, chicken, veg and reheats, the air fryer earns its place with 8.5L capacity. It is also cheaper to run than heating a full-size oven - check the current Amazon UK price, as it changes often.
Is the Cosori big enough for a family?
The air fryer has 8.5L capacity. As a rough guide, 4-5L suits 1-2 people, 6-8L suits 3-4, and larger or dual-drawer models suit families of 4 or more.
What are the downsides of this air fryer?
Air fryers take up worktop space, cook smaller batches than a full oven, and some foods still need a light oil spray. They are best for crisping and reheating rather than replacing every oven job, which is why they suit some kitchens better than others.
Is the Cosori cheaper to run than an oven?
For small and medium portions, usually yes - the Cosori Dual Air Fryer heats a much smaller space than a full-size oven and cooks faster, so it uses less energy. For large meals that fill a big oven anyway, the saving is smaller. Exact cost depends on its wattage and your tariff.
What can you cook in the air fryer?
This air fryer has 8 cooking functions covering jobs like air-fry, roast, bake, grill and reheat. Beyond chips it handles chicken, fish, veg, bacon and reheating leftovers crisply; baking and dehydrating are possible on models that offer those modes.
Is the Cosori easy to clean?
The drawer and crisper plate wipe or wash clean; non-stick coatings make this easier. Clean it after each use, as baked-on grease is harder to remove later.
Do you need oil in the air fryer?
Little or none - the Cosori circulates hot air to crisp food, so most things need only a light spray of oil or none at all. Naturally fatty foods like sausages need no added oil, while a fine mist helps fresh chips and breaded items crisp up.
