Capacity comes first. A 12-litre cavity gives room for larger trays and a rotisserie. The 7.2-litre Philips is the smaller unit. Glen lists its dimensions as 320 x 380 x 370 mm (W x D x H), so measure your counter before you order. The other pages do not give dimensions.
Power and timer come next. Glen and Philips list 2000 watts. The 12-litre AGARO, Pigeon and Prestige list 1800 watts. Longer timers help with roasts. AGARO, Pigeon and Glen offer up to 90 minutes, and Philips lists a shorter range in its table.
Then look at the accessories. AGARO and Glen list long accessory sets. Prestige lists trays and a rotisserie. Pigeon names a rotisserie function.
A cook who wants the largest cavity should start with the 12-litre units. The AGARO Regency Air Fryer Oven 12L lists a rotating basket, a rotisserie fork, a skewer rack, two mesh racks and a drip tray. The Glen 12L Air Fryer Oven lists a rotating mesh basket, skewers and a rotisserie shaft. Both give a two-year warranty.
A cook who cares about the build can compare the Pigeon 12L Air Fryer Oven and the Prestige AirChef 12L Air Fryer Oven. Both are stainless steel and carry an ISI mark. Pigeon says its glass door lets you monitor cooking. Prestige says its 360° rapid air technology circulates hot air from all angles.
The best overall pick here, and the choice for low-temperature work, is the Philips Air Fryer Oven NA342/00 7.2L. It has a cooking window and a digital LED display. Philips says low-temperature settings suit dehydrating and fermenting curd. The table and the description give different temperature ranges, so read the maker page before you order.
Some pages leave out key details. Pigeon does not state a warranty, and Prestige does not state a timer. Glen and AGARO do not describe their controls. Check the manual or the retailer page for each gap before you decide.
Safety wording differs as well. AGARO lists three security features: overheating protection, automatic shut-off and circuit overload protection. Pigeon and Prestige carry an ISI mark. The Philips page gives a 1.8 m cord, which helps if your socket sits far from the counter.
