Dual zones for smart cooking, but baskets are small.

Gifted the 6.2 l touch model with see through to mom Phillips is absolutely the best if you have budget go for the one i bought for 10k going in sale for 8.6k
I love my Philips 2000 Series 6.6QT (6.2L). It works great, it's very easy to clean, and I really like the window. I don't have any experience with the other one.
I only cook for myself and it is plenty big enough for that. I would say it's big enough for 2 people's worth of one thing like fries, wings, breasts, etc. Maybe even 3 people's worth depending how much you eat. The downside is cooking one thing at a time. Also remember that there is a divide in the dual basket so it might be harder to cook big things even with a larger capacity.
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.
Gw pake Phillip NA 2000 230 kapasital 6,2L. Oke2 aja sih ini. Beli buat pelengkap aja, jadi kalo makanan berkuah di microwave, kalau yang kering2 pakai ini
I am happy with Philips 2000 series.
Ha mer de gholt vor einige Mönet und bin top z fride demit Macht was er sött und das ohni Problem. Philips 2000 Series Airfryer
Very happy with my Philips 2000 series airfryer. Easy to use, easy to clean, doesn't take up much space in storage. A single basket is enough for what I need it to do. The complete machine feels very sturdy. Friends of mine have a Ninja. No complaints there either.
