COSORI Dual Air Fryer 9-Quart — In-Depth Review
The COSORI 9-Quart offers 1 quart less in total volume, but many users prefer its viewing windows. Unlike the Ninja, where you must open the basket to check on your meal (losing heat in the process), the COSORI allows you to monitor progress via internal lights and clear panels.

Cooking Performance Comparison
Both models deliver crispy, evenly cooked results, but they handle the “Dual Zone” workflow differently:
- Ninja DZ401 excels with mixed meals (e.g., chicken + vegetables) using different temperatures.
- Ninja’s Smart Finish: This ensures two different foods—like salmon and asparagus—finish at the exact same time, even if they have different cook times. The IQ Boost feature intelligently distributes power across both baskets for faster results.
- COSORI 9Qt shines when cooking similar foods at the same settings.
- COSORI’s Versatility: COSORI includes a Shake Reminder and a dedicated Preheat function, which Ninja notoriously lacks. The COSORI also tends to offer more “one-touch” presets for beginners.
If you frequently cook different dishes at once, Ninja’s advanced syncing provides more control.
In daily cooking scenarios, the Ninja DZ401 vs COSORI Dual Air Fryer comparison reveals that Ninja’s independent temperature control is especially useful when cooking raw proteins alongside vegetables that require gentler heat.
Cleaning & Maintenance
For everyday meals, the Ninja DZ401 vs COSORI Dual Air Fryer difference becomes noticeable in cleanup and storage, with COSORI feeling easier to handle in smaller kitchens and tighter counter spaces.
The Ninja Advantage: The DZ401 features ceramic-coated baskets. This is a major selling point for health-conscious buyers avoiding Teflon (PTFE). Ceramic is generally more durable and easier to hand-wash without the risk of the coating flaking over time.
The COSORI Ease: COSORI uses high-quality non-stick Teflon. While it is incredibly easy to wipe down, it requires more care with abrasive sponges to maintain its lifespan.
Both air fryers include:
- Nonstick baskets
- Dishwasher-safe components
- Easy-wipe exterior surfaces
COSORI edges slightly ahead for users who prioritize fast cleanup due to its lighter baskets. Over weeks of daily use, the Ninja DZ401 vs COSORI Dual Air Fryer experience shows COSORI’s lighter baskets are easier to shake and remove, which matters when cooking multiple batches back-to-back.
Energy Efficiency & Noise
- Comparable wattage and energy usage
- Ninja is slightly louder during high-heat cooking
- COSORI runs marginally quieter
