Quick Summary
The Olsen and Smith 11L Vertical Dual Stack Air Fryer is a space saving dual zone air fryer for easier family meals, better timing and healthier cooking with less oil.
What This Product Is Used For
The Olsen and Smith 11L Vertical Dual Stack Air Fryer is used for cooking two different foods at once with separate temperatures and times. Its vertical design gives 11 litres of total cooking space across two 5.5 litre baskets while taking up less worktop area than traditional side by side models.
Compared with a standard deep fryer, this air fryer uses up to 90% less oil, making it suitable for frying, cooking, grilling and baking with a healthier approach. The viewing windows and light function also let you check food progress without opening the drawers.
A single basket air fryer may suit simple snacks, but users choose this model when they want dual zone cooking, larger family capacity and a more compact footprint.
Who This Product Is Best Suited To
This product is best suited to users who want to cook a main and side at the same time without juggling separate appliances or batches. It suits people who need generous capacity but want to save worktop space, especially in kitchens where a wide side by side air fryer would feel too bulky.
It is also useful for beginners and confident cooks who want preset programmes, manual control, viewing windows and flexible cooking for family meals.

Real World Performance and Day to Day Use
In day to day use, the Olsen and Smith 11L Vertical Dual Stack Air Fryer is designed to solve two common air fryer problems: lack of space and awkward meal timing. The upright design gives two 5.5 litre baskets in a narrower footprint, while the overall 11 litre capacity makes it suitable for family cooking.
The two independent baskets allow different foods to cook at separate temperatures and times, helping avoid flavour crossover when preparing a main and side together. The Sync function helps both baskets finish at the same time, while Match mirrors settings across zones when cooking the same food in both baskets.
The viewing windows with light function help remove the worry of overcooking or checking too often, and the 13 presets make common foods such as chips, chicken, fish and vegetables easier to prepare. The 50 to 200°C temperature range, 0 to 60 minute timer and 1700W power give practical control for everyday meals.
Choose this if you want a space saving dual zone air fryer with large capacity, viewing windows and smart timing functions.
Skip this if you need a lighter, smaller appliance that can be moved in and out of storage every day.
Why We Like This Product
The YPC Team likes this because it gives buyers full dual zone cooking without the wide shape of a traditional side by side air fryer. It helps buyers avoid the mistake of choosing a large appliance that dominates the worktop, and it reduces the regret of buying a single basket model that makes full meal timing harder.
