We all know that sometimes it can take fifteen to twenty minutes to preheat our standard ovens. Because the air fryer is so compact, that preheat time is cut down to two or three minutes! That’s a huge savings in time as well as energy. In the summer, you can preheat your air fryer and not heat up the whole kitchen. In addition, the intense heat created in the air fryer cooks foods quickly, about 20% faster than in an oven, so you’re saving time and energy there as well. No one these days seems to have time to spare, so this should please everyone!
