Most home kitchens benefit from a 1.6‑1.9 cu ft capacity, which fits standard dishes and a 12‑13‑inch turntable. Models like the Black+Decker and ThermoMate offer 1.7 cu ft, while GE’s larger option provides 1.9 cu ft for bigger roasts. Choose the size that matches the largest dish you regularly cook to avoid cramped heating.

CFM (cubic feet per minute) measures how much air the vent can move; higher numbers clear smoke and steam faster. All listed units deliver 300 CFM, but Black+Decker and Midea include a two‑speed fan for flexible suction, while GE’s models also provide 300 CFM with a quiet low‑speed option. Opt for a dual‑speed fan if you cook frequently with strong odors.

A 6‑in‑1 Black+Decker model adds air‑fry, convection, grill, bake, and roast, letting you replace a separate countertop appliance. If you value healthier cooking and space savings, the added functions justify the higher price. However, if you only need basic reheating and defrosting, a standard 1000‑W microwave will be more economical.

All the featured microwaves deliver 1000 W output, which provides fast, even heating for most meals. Models with 10 power levels, like Black+Decker and ThermoMate, let you fine‑tune intensity for delicate foods, while basic 5‑level units may require more trial‑and‑error. Higher wattage shortens cooking times, but precise power levels improve texture for items like cheese or chocolate.

Black+Decker focuses on versatility with multi‑stage cooking, air‑fry options, and a spacious 1.7 cu ft cavity, while GE emphasizes sensor cooking, a sleek stainless finish, and bundled extended service plans. GE’s 1.6‑cu ft model includes auto‑defrost and a turntable‑off feature, whereas Black+Decker offers quick‑press power shortcuts. Your choice depends on whether you prioritize extra cooking modes or sensor‑driven convenience.

Sensor microwaves, like GE’s JVM7195SKSS, automatically adjust time and power based on moisture, reducing over‑cooking and saving guesswork. Auto‑defrost programs on Black+Decker and Farberware simplify thawing by calculating optimal settings from weight inputs. These features are especially helpful for busy households that want consistent results without manual timing.

A larger turntable (12.4‑13.6 in) accommodates full‑size plates, pizza, and even a small rotisserie chicken, ensuring even heat distribution. Models with a 12.5‑inch turntable, such as Midea, provide the most flexibility for bulkier items. If you frequently cook large dishes, prioritize a microwave with a turntable of at least 12 inches.

Extended protection plans, like the 2‑year premium coverage offered with many GE units, can save on repair costs for motor or vent issues. Check if the manufacturer includes a charcoal filter replacement kit, as seen with GE and ThermoMate, to maintain ventilation performance. A solid warranty combined with easy access to service centers adds long‑term value beyond the initial purchase price.
