The decision in plain terms
Choose 1000 Series Airfryer 3.4 Qt if you want the smaller advertised capacity. Choose 3000 Series Airfryer 6.5 Qt if the larger advertised capacity fits your batch plan.
The key documented difference is advertised capacity. That difference does not establish a proportionate change in usable cooking area, portions or cooking speed. There is no hands-on performance winner or live-price winner in this comparison.

What could change your choice
Measure the food footprint you need, inspect the manual's clearance instructions and confirm exact-model accessories. Unknown dimensions and coating chemistry are not equivalent to zero or an adverse finding. Current price, stock and personal budget can reverse a specification-based preference.

NA110/00: model-specific notes and limitations
Manual time and temperature dials with RapidAir circulation. Philips advertises twelve cooking methods; we list only the ones it names individually. We do not use electrical or dimension figures from other regions’ versions. The US manual asks for at least 10 cm at the back, both sides and above (converted exactly in the specifications); front space is not quantified. The US spec data labels the product 14.0 in long, 10.1 in wide and 11.0 in high; we read length as front-to-back depth.

NA330/00: model-specific notes and limitations
Philips’s US catalog confirms this exact model (not a refurbished R0 version), its quart-labelled capacity, a cooking window and RapidAir Plus. Refurbished R0 versions and the cosmetic NA331 variant are not listed as separate models. The full mode list and exact US electrical ratings have not yet been confirmed from the manual.
