First, we need to discover the difference, an air fryer oven is different from a conventional oven.
Air fryer ovens use a large fan at the top to create convection to heat the food evenly in the oven.The traditional electric oven only uses a fan to heat it.
Just like an air fryer, an air fryer oven is not a quiet machine and produces the sound of a fan spinning while it is working.
This sound is the sound produced by the machine during normal operation and is not dangerous.
If noise has to be rated, HYSapientia's air fryer oven is quieter than a hair dryer but louder than a microwave.
All air fryer ovens generally produce the same level of noise, but that's just something you should be aware of.
The movement of air makes food crispier, so don't get me wrong. You just need to enjoy the deliciousness that the air fryer oven brings to you.
