Air fryer vs OTG vs convection microwave: which one should you buy?

People search this as “air fryer vs OTG vs convection microwave which to buy” · updated 2026-08

Short answer

Buy an air fryer if you mainly want crisp snacks, reheating and small-batch roasting with little oil. Buy an OTG if you bake cakes and bread regularly. Buy a convection microwave if counter space is tight and you need reheating plus occasional baking in one machine. For most Indian homes, an air fryer plus a plain microwave covers 90% of daily use.

  • Air fryer = fast circulating hot air, best crisping, small capacity.
  • OTG = true baking with top/bottom heating elements, best for cakes and bread.
  • Convection microwave = jack of all trades, master of reheating.

Common follow-up questions

Can an air fryer bake a cake?

Small cakes, yes, in a fitting tin. It cannot match an OTG for even rise or larger batches.

Is air frying healthier?

It uses far less oil than deep frying for a similar texture, which cuts calories. The food itself still matters.
