Capacity and Size
With an 8.6L cooking capacity, this air fryer is designed for larger batches, such as family-sized meals or cooking multiple items at once. It uses a dual-zone layout with two drawers, allowing separate portions to be prepared or combined as needed. A removable divider is included to adjust the usable space for different food shapes, whether flatter items or taller pieces. Both drawers are sized for everyday cooking volumes, though very large cuts may still need trimming.
Cooking Performance and Functions
Cooking performance two-drawer design, letting two dishes cook at the same time while keeping portions separate, then combining them later if a recipe requires it. It uses a PFAS-free ceramic coating to support easier cleanup and help prevent food sticking during cooking. The product also claims "No Flipping Even Cooking, " which is intended to deliver even results without manual turning, although performance can still vary by recipe and ingredient moisture levels. A removable divider helps manage space when cooking different items, and dishwasher-safe parts reduce the workload after cooking.
Single or Dual Zone
This model uses a dual-zone, two-drawer setup, so it can cook two dishes at the same time while keeping portions separate. The Cosori has an 8.6L total capacity, split across its two drawers, and it includes a removable divider that lets you combine space when you need room for a larger item. The dual drawers make it possible to work in parallel, rather than waiting for one batch to finish before starting the next. If one drawer is unused, the available space may feel uneven, and keeping dishes separate can reduce convenience when meals require fully aligned cooking times.
Ease of Use and Controls
Because the air fryer uses two drawers with a removable divider, controls and loading habits matter alongside capacity. Each drawer can be operated independently, which helps when different foods need different cook times and temperatures, although it does call for careful coordination across both zones. Typical use involves placing one basket in each drawer, then setting temperature and time before starting both zones together. Using the removable divider changes how larger items fit, so loading needs a bit of planning. Controls are straightforward overall, but a short trial run helps beginners get used to managing two independent drawers.
Cleaning and Maintenance
Cleaning and maintenance are straightforward, provided the drawers are wiped down straight after cooking and allowed to cool first. The Cosori has two removable drawers, which can be emptied, rinsed and cleaned individually. The removable divider can also be washed, helping when switching between different foods. For everyday cleaning, warm soapy water and a soft cloth lift grease and residue, then everything should be dried thoroughly before reassembly. The parts are dishwasher safe, so clearing any stuck-on bits beforehand improves results. The outer body only needs a damp wipe, and spills should be cleared quickly, then the unit left to dry fully before use.
Noise and Energy Use
Noise and energy use are mainly influenced by how the dual drawers are operated. Each drawer can cook different foods at the same time, but the unit still needs time to heat. With two zones, performance depends on whether both drawers run simultaneously, or only one side is used. Preheating followed by cooking typically creates the loudest periods, because the fans and heating elements cycle during temperature control. Energy use can also vary with portion size and how evenly foods fit within the 8.6L total capacity, particularly when using the removable divider. For lower noise, running matched cooking times can help reduce extra cycling.
Who Is This Air Fryer For?
Who the air fryer is for depends largely on cooking style and how much space is needed. It suits people who want to cook two items at once, since it is an 8.6L dual-zone model with two drawers and a removable divider, allowing the capacity to scale up or down. Families or batch-cookers may find the larger total capacity useful for preparing meals without needing to split ingredients into separate rounds. It also suits households that prefer easier cleanup, because parts are dishwasher safe. Buyers who only cook single dishes at a time, or who need very small portions, may find the extra capacity unnecessary.

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 8.6L capacity and two drawers so you can cook two things at once. 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 8.6L capacity, split across two drawers, so the usable space per drawer is smaller than the total suggests. 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 (dual-zone models are bulky), 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 Blaze Air 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.
Can the air fryer cook two things at once?
Yes - this air fryer has two separate drawers, so you can cook two foods at different temperatures and times, and finish them together. It is ideal for a main and a side, though it takes up more worktop space than a single-drawer model.
Is the Cosori easy to clean?
The air fryer has dishwasher-safe parts, so the drawer and crisper plate can go in the dishwasher; a quick wipe of the inside after use keeps it fresh.
Do you need oil in the Cosori?
Little or none - the air fryer 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.
