If you've been thinking about upgrading to a new air fryer, you've probably come across the brand Ninja.
This US manufacturer was named the No.1 air fryer brand in the UK last year and has a mantlepiece sagging under the weight of its industry awards to prove it. The catch? Ninja air fryers can be pricier than those from its main competitors, so it's not always the most affordable option when looking to upgrade.
But that's all changed today.
With the arrival of Prime Big Deal Days 2025, the second site-wide sale launched by Amazon exclusively for those who are subscribed to its loyalty scheme, Ninja air fryers have plummeted to record-low prices. The standout deal is the dual-drawer Ninja Foodi Dual Zone.
Ninja Foodi Dual Zone usually costs £219, but has been slashed to £119 for Prime members today.
If you're not subscribed to Amazon Prime, sign-up for a 30-day free trial to unlock access to the price cut.
The Ninja Foodi Dual Zone offers a combined capacity of 7.6 litres between both drawers, so families can cook an entire meal without switching on an oven, or cater to different tastes. Each drawer fits up to 1kg of chips or an entire 1.6kg chicken, Ninja claims on the listing. Food is cooked up to 75% faster than fan ovens, including pre-heat times.
Ninja Foodi Dual Zone dual-drawer air fryer plunges to lowest price this year
If you're looking for something a little bigger, this flagship dual-drawer model from Ninja is the best option. It boasts two vast 3.8-litre drawers for a total capacity of 7.6 litres. Ninja says that's enough to cook a 1.6kg chicken or 1kg of fries in each drawer without using your oven. You can synchronise both drawers to finish cooking at the same time, and set them individually to different temperatures.

As well as different preset heat modes (Max Crisp, Air Fry, Roast, Bake), including temperatures up to 240°C, the Ninja Foodi dual-drawer air fryer also has dedicated buttons to Reheat and Dehydrate meals.
Each drawer can be set to a different temperature, with cooking time synchronised to finish at the same time — making it easier to time your cooking.
With standalone 3.8L drawers, the Ninja Foodi Dual Zone is more flexible than traditional air fryers

The term "air fryer" is somewhat misleading, as these clever kitchen gadgets aren't only about crisping up homemade chips with 75% less fat than a traditional deep-fat fryer. Air fryers can do everything you'd do in a fan oven, from baking desserts to cooking entire meals, and with a lot less electricity.
And Britons have flocked to these must-have kitchen gadgets. Research from Leatherhead Food Research suggests between 30 – 46% of Britons have now switched to an air fryer. If you're still missing out on the faster cooking speeds, lower energy bills, then this Ninja Foodi Dual Zone air fryer is a good pick.
If you're short on countertop space, the Ninja Double Stack Air Fryer is designed to offer the same cooking power but with a smaller footprint
|NINJA PRESS OFFICE
Short on space? One of the newest additions to the Ninja lineup has also been included in the Amazon sale for the first time.
Dubbed the Ninja Double Stack Air Fryer, this model was unveiled by the US brand earlier this year to solve one of the biggest headaches with its devices — the amount of countertop space required to store them.
If you don't have a lot of spare work surface, but want one of the dual-drawer models for the extra cooking capacity, the Ninja Double Stack Air Fryer could be the solution. In a world first, this clever model stacks the two drawers on top of one another — minimising the amount of room required.
Outside of a sale, this is one of the priciest Ninja air fryers available, with an RRP of £269.99. However, Prime members can snag this space-saver for its lowest-ever price today. Amazon has slashed £85 off the price tag to return the Ninja Double Stack XL Air Fryer to its record low price.

Unveiled earlier this year, the Ninja Double Stack XL brings the vast capacity of the dual-drawer Foodi Max but squeezes it into a footprint much closer to the standard single-drawer Ninja air fryer models. If you're short on countertop space in your kitchen, this could be a worthy investment to forgo your oven and cook food faster and using much less energy.

Ninja says its designers have managed to reduce the overall width by 30% compared to the dual-drawer Ninja Foodi Max above. Despite this slimmer profile, the Ninja Double Stack Air Fryer has the same total 9.5 litre capacity, so you'll be able to cook the same amount of food. Based on research conducted by Ninja, this model is capable of cooking enough food to feed eight people in a single session.
It boasts six different cooking modes: Air Fry, Max Crisp, Roast, Bake, Reheat & Dehydrate.
Finally, Ninja CRISPi is a portable solution from the US manufacturer that can be snapped to either a 1.4-litre or 3.8-litre transparent TempWare glass container — then cook, serve and store all in the same vessel. The glassware is PFAS-free, heat-resistant, and dishwasher safe for easy cleanup.
This clever gadget offers modes like Air Fry, Roast, Recrisp — great for reviving leftovers, and Keep Warm. The modular "PowerPod and glass serving bowl" system intelligently senses which container is attached and adapts the temperature appropriately. Max heat sits around 185 °C — not the hottest in the category, but usually enough for most frying and roasting tasks.
The CRISPi is ideal for singles, couples, small kitchens or those who value portability and low clutter.
It only launched in the UK earlier this year, so it's exciting to see the Ninja CRISPi included in the latest Prime Day sale from Amazon. Usually £149.99, this modular model has plummeted to just £124.99.
All-new Ninja CRISPi Portable Air Fryer drops to lowest-ever price
The newest Ninja CRISPi Portable Air Fryer is a next-generation kitchen gadget built for compact homes. Its modular system combines the "PowerPod" with four cooking modes and a TempWare glass container. Ninja includes two of these PFAS-free and dishwasher-safe vessels, with a choice of 1.4L or 3.8L.
