Nuwave Air fryer is pretty much like the Philips Airfryer and I think it is a slightly better as well. The Nuwave Air fryer comes in different capacities and you can choose whichever capacity fulfills your needs.
The Airfryer from Nuwave comes even with 10 qt. capacity air fryer which is pretty huge and can cook a lot of food at once. I do not remember seeing any other company with that larger capacity air fryer so, at the time of writing this post, I guess this brand has the largest air fryer one can possibly imagine.
