Updated August 2026 — full head-to-head comparison.

Design and Size

The COSORI Air Fryer 2.1 QT and the CRUX x Marshmello 3.0 QT Digital Air Fryer both feature compact designs tailored for small kitchens. The COSORI has a smaller capacity of 2.1 quarts, making it ideal for minimal meal portions or snacks, while the CRUX offers a slightly larger capacity of 3.0 quarts, suitable for feeding 2 to 4 people. The COSORI's dimensions are compact, measuring 10.1 x 8.3 x 10.5 inches, making it especially fitting for dorms or RVs. In contrast, the CRUX's design combines style and functionality, enhancing any kitchen countertop without taking up excessive space. This extra room in the CRUX allows for more versatile meal preparation.

Cooking Technology

The COSORI Air Fryer utilizes advanced cooking methods with its 4-in-1 functions, including Air Fry, Reheat, Roast, and Bake, delivering crispy results with up to 97% less oil. This efficiency makes it an excellent choice for health-conscious users. On the other hand, the CRUX x Marshmello incorporates TurboCrisp technology, which allows it to cook meals up to 50% faster than traditional ovens. The powerful 1300-watt heating system ensures that food is cooked evenly and retains moisture, making it particularly effective for a variety of recipes. Both air fryers offer innovative cooking solutions, but the CRUX stands out for speed.

Ease of Use

The CRUX x Marshmello makes cooking simple with its fully programmable touch panel and pre-set cooking functions, which streamline the process for users. It also features a 60-minute auto shutoff timer to enhance safety. The COSORI Air Fryer, while also user-friendly, focuses on customizable cooking with a straightforward interface. It includes 30 in-app recipes for users looking to explore new meal options. While both air fryers are designed with convenience in mind, the CRUX's touchscreen control and quicker cooking times may appeal more to those who prioritize efficiency.

Health and Nutrition

When it comes to health, both air fryers promote healthier cooking. The COSORI Air Fryer claims to use up to 97% less oil, allowing users to enjoy crispy meals with minimal added fat. The CRUX x Marshmello also emphasizes healthier eating, using up to 75% less fat in its cooking process. This makes both products excellent choices for those looking to reduce their oil intake. However, the COSORI's superior oil reduction percentage could be a deciding factor for individuals particularly focused on minimizing fat content in their diets.

Cleaning and Maintenance

Cleaning is straightforward with both models. The COSORI Air Fryer boasts a nonstick, dishwasher-safe basket, making it easy to maintain. Similarly, the CRUX x Marshmello offers a dishwasher-safe cooking basket and crisping tray, which also eliminates the hassle of cleanup. Both air fryers are designed to make post-cooking maintenance as effortless as possible. However, the additional silicone cupcake molds included with the CRUX may offer more versatility for users looking to experiment with dessert options, enhancing its appeal in terms of fun and creativity.

Price Point

The COSORI Air Fryer is priced at $59.99, while the CRUX x Marshmello comes in at a lower $49.99. This means the CRUX is about 17% cheaper than the COSORI, making it a more budget-friendly option. Despite the price difference, both air fryers deliver excellent value for their respective features. The choice may come down to which features are more important to the user, as the COSORI provides a slightly smaller capacity but with advanced oil-reduction technology, while the CRUX offers faster cooking times and a larger capacity.

Performance and Popularity

In terms of performance, the COSORI Air Fryer has a sales rank of 4326, indicating a solid level of popularity among consumers. The CRUX x Marshmello, however, has a higher sales rank of 22303, which may suggest it is less popular among buyers compared to COSORI. This difference could reflect consumer preferences for the specific features and cooking technologies each air fryer offers. While both products perform well, the COSORI's higher sales rank may give it an edge in customer satisfaction.

Which should you buy?

If you're looking for a compact, lightweight air fryer that uses minimal oil and offers diverse cooking functions, the COSORI may be the better choice.
