Part supermarket, part budget-friendly emporium, Aldi has become the go-to store for everything from treadmills and beauty tools to kitchen appliances and more, thanks to its range of ever-changing Specialbuys that grace the middle aisle. With Specialbuy products typically available at a fraction of the price of alternatives from big-name brands, they don’t tend to hang around for long. However, if you previously missed out on Aldi’s purse-friendly air fryer, the good news is it’s about to be restocked, and it’s more than £100 cheaper than the popular Ninja foodi. Similar to the Tower elite flexi-drawer air fryer, Aldi’s combi zone air fryer (£49.99, Aldi.co.uk) features one large drawer that can be separated into two with a divider. It boasts a 9l capacity in total, meaning it should be large enough and versatile enough to feed a family of three to four.With a temperature range from 40C-200C and 10 preset programs, the air fryer even enables you to choose individual or simultaneous settings within the drawer’s chambers. It also boasts a digital LED display, preheat function, overheat protection function and it comes with a digital recipe book accessible via a QR code. Even better, Aldi’s air fryer comes with a three-year warranty, for extra peace of mind. Plus, for those with smaller kitchens, Aldi is launching a 3.5l single-drawer air fryer (£29.99, Aldi.co.uk).Read more: Aldi’s new budget ice cream maker looks like the Ninja creami When can you buy Aldi’s affordable air fryer?Aldi’s air fryers will be in stores from 16 July, as part of the supermarket’s Modern Kitchen range.
