Capacity looks close across the group, so focus on controls. The Philips NA130 is the only one with analogue knobs. The other four use digital displays or touch panels.
Power comes next. American Micronic and the Philips NA130 share the highest figure at 1700 watts. Wonderchef lists 1600 watts and Faber lists 1500 watts. Philips NA231/00 gives no figure, so ask the seller.
Look at the extras. Wonderchef offers a lit window. Philips NA231/00 offers a window. Faber names overheat protection. American Micronic names a cool-touch handle.

A family that prefers plain controls has one choice. The Philips Air Fryer NA130 6.2 Litre has timer and temperature knobs. It lists 1700 watts, an 80-200°C range and a two-year warranty. Philips says the starfish design pan cooks evenly without flipping food.
A buyer who wants a digital panel can compare three models. The Faber 6L Digital Air Fryer lists eight pre-set functions and overheat protection. The Philips Air Fryer NA231/00 6.2L lists 13 preset modes and a cooking window. The American Micronic 6.5 L Digital Air Fryer lists eight preset menus and an LCD touch display.
Cleaning and viewing favour the Wonderchef Evita Digital Air Fryer 6.5L. Its window has an in-built chamber light, and the warranty is two years on-site. The page gives no presets or temperature range.
A household of five or six people can read the American Micronic page, since the maker says the unit suits 5-6 persons. The Faber is the smallest basket in the group at 6 litres.
Every model lists two years, so warranty does not separate the group. Four of the five pages leave out the cord length, so check the retailer page if socket distance matters.
Timers differ too. The Philips NA130 lists 0-60 minutes, and the American Micronic lists a 60-minute timer. The Wonderchef has an adjustable timer that shuts off when food is ready. The Faber lists a timer without a range, and the NA231/00 gives none.
Basket details differ. The Philips NA130 has a non-stick basket coating. The Faber has a detachable non-stick container, and the Wonderchef has a non-stick coated removable basket. The Philips NA231/00 and American Micronic pages give no coating.
Presets split the group in three. The Philips NA231/00 lists 13. The Faber and the American Micronic list eight each. The Philips NA130 and the Wonderchef give no preset count.
