Dual zones excel, but bulky with small baskets.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
ninja is mid ngl, round basket sucks and online shipping is a hassle. just go for the philips, it's way easier since there's a store warranty nearby
I have the NA231. I like it a lot. It works very well. It is easy to clean. PTFE is fine. Air fryers don't get hot enough for it to be an issue. Personally I would not choose the Instant Pot because it doesn't have a window. I use the window a lot and would never buy an air fryer without one. Of course that is just a personal preference.
First of all, stay far away from 2QT. That is way too small. Also, there are some decent cheap brands like Gourmia and Chefman. I actually got a nice Philips 6.6QT pretty cheap ($90 CAD/$65 USD) and I love it. Got my mother an 8QT Chefman for the same price.
5ish minimum. I use mine for just me and I wouldn't want much smaller than my 6.6. A light eater might be ok with like 4QT but I guarantee you will soon wish you had something bigger. Better too big than too small.

yes good to go for 3-4 people...I got it for 8.3k from flipkart https://preview.redd.it/o7mht29p4aag1.jpeg?width=4284&format=pjpg&auto=webp&s=b14f4412e35acd33b89e29ef4935a55d88b66c6b
Recently got the philips na231, 6.2l. So far so good, after discount 6790.
Agree, I have been using it for the last 4 months
Buy the touchscreen version 6.2l, just bought it 2 months ago. Excellent
Yes, for me. The older one, with knob, in this the timer doesn't stop if you remove the food to check or give the food bucket a toss. In touch screen, it does stop.
I bought 6.2l Philip air fryer, and it has been asking the best decision i have made. I use it everyday for 15 mins to bake chicken. Was pondering for last 2v years whether to buy or not, will it even work, is it even worth? And to my surprise, it's not essential in my kitchen.
