Capacity and Size
The air fryer is built around a 10L family size capacity, split into two separate drawers. This dual-drawer layout supports cooking two items in parallel, or keeping food apart for different dishes. Each drawer can also be used on its own, which suits smaller portions. In terms of size, the review says the overall footprint works for countertop use, but it does not provide exact dimensions, so the capacity is best assessed through the drawer volume and how meals are portioned for the two compartments.
Cooking Performance and Functions
Cooking performance using Dual Blaze Even Cooking to help food cook thoroughly. With a 10L family size, it supports batch cooking, and the removable divider enables single-space or split cooking for different items at the same time. The divider supports flexibility when items require separate cooking conditions, but doneness still depends on food thickness and how each dish responds to airflow. App control adds convenience for checking progress and adjusting settings remotely. After cooking, the PFAS-free ceramic coating is designed to help make cleaning easier, although residue may still need manual wiping.
Single or Dual Zone
This air fryer can be used in a single cooking space or split into two separate zones, which can affect when different foods reach the desired doneness. It has two drawers, so one side can cook items such as chips while the other cooks chicken, helping stagger timing more evenly. With the divider removed, the full 10L family capacity can be used in one continuous cavity, which suits batch meals that benefit from cooking everything using one routine. The dual layout also helps when foods cook at different speeds. The main downside is reduced usable space per drawer when foods need similar doneness, since splitting limits how much can be cooked together.
Ease of Use and Controls
Ease of use and controls on the Cosori centre on switching between single and dual-zone cooking, then using the app to manage the process. The unit supports single and dual-zone cooking with two drawers, and a removable divider separates the zones when required. Typical use involves placing food into one or both drawers, selecting the appropriate mode, and confirming the divider is positioned correctly. App control supports guidance through the cooking process, with timing and instructions handled via a phone.
Cleaning and Maintenance
Cleaning and maintenance are usually straightforward with the air fryer, because the two drawers can be handled separately and the divider can be removed when needed. After cooking, it helps to let the unit cool, then pull each drawer out and wash them using warm, soapy water. Divider pieces can be cleaned the same way, and the removable part makes it easier to reach trapped grease. The ceramic coating is PFAS-free, so The Cosori FlexDrawer Smart Air expects gentle care, avoiding abrasive scrubbers. Wipe the outer housing with a damp cloth, then dry fully before storing.
Noise and Energy Use
Noise levels and energy use depend primarily on how the FlexDrawer is run, since it can cook in single-zone or dual-zone modes. In single-zone use, one drawer handles the cooking task while the other side stays idle, which can reduce total demand. In dual-zone use, both drawers operate together, so the cooking period can feel louder and more noticeable in a kitchen. Energy use also rises when larger, family-size meals are prepared in the 10L capacity, because more food mass needs longer heating to finish evenly.
Who Is This Air Fryer For?
Who this air fryer is best suited to depends on how a household cooks, and the Cosori is built around two cooking modes. It works well for families or shared kitchens that want a 10L family size and the option to use two drawers, either separately or together. The removable divider supports flexible batch sizes, which helps when one person needs different sides. App control suits people who prefer to manage reminders and settings from a phone rather than standing by the unit. Buyers who mainly cook single items may find the dual-drawer setup less necessary.
Where to Buy in the UK
Finding a reliable place to buy the air fryer in the UK starts with checking where retailers list the exact model name and features, since availability can vary by stock status. They should look for listings that mention app control, a PFAS-free ceramic coating, dual blaze even cooking, and dual drawers with a removable divider for single or dual-zone cooking. The 10L family size is also a key check, because other shaped models may differ. Shoppers can compare Amazon UK, John Lewis, Currys, AO and Argos listings, then confirm stock, return terms and delivery dates before ordering.
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 10L 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 this air fryer big enough for a family?
The Cosori has 10L 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 the Cosori FlexDrawer Smart Air?
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 air fryer cheaper to run than an oven?
For small and medium portions, usually yes - this 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.
Can the Cosori cook two things at once?
Yes - the 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 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 FlexDrawer Smart Air 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.
