Space heaters don’t usually win people over with innovation, but small design decisions can make a noticeable difference in daily use. The Midea 23-inch Dual-Flex Heater focuses on flexibility, fast warm-up, and quiet operation rather than chasing unnecessary features.
Originally $59.99 and now only $49.99 for a limited time at Costco (save $10!), the Dual-Flex is aimed at shoppers who want dependable supplemental heat without paying for bells and whistles they’ll never use.

Flexibility That Feels Purposeful
The ability to run the heater either vertically or horizontally is the defining feature here. In practice, that means it can stand like a traditional tower or sit low along a wall, depending on what the room layout calls for.
That flexibility matters most in smaller spaces, where heaters often compete with furniture, desks, or walkways. Instead of forcing a room to adapt, the Dual-Flex adapts to the room.
Fast Heat Without Added Noise
Midea’s WhisperBoost Technology is designed to deliver warmth in seconds, which makes the heater feel responsive rather than sluggish. This is especially noticeable during short work sessions or early mornings when waiting for heat defeats the purpose.
With a rated noise level of 48 dBA, the Dual-Flex stays quiet enough for sleeping, watching TV, or joining video calls without constant fan awareness.
Practical Features, Clearly Defined
Instead of overcomplicating the interface, the Dual-Flex sticks to controls that are easy to understand:
- Three heat levels plus ECO and fan-only modes
- Adjustable thermostat from 41°F to 95°F
- 60-degree oscillation for more even heat distribution
- Built-in timer and included remote control
Rated at 1500W, the heater is best suited for rooms between 100 and 299 square feet, making it ideal for bedrooms, home offices, and other personal spaces rather than large open areas.

For shoppers who value flexibility, quiet performance, and a sensible feature set, the Midea 23-inch Dual-Flex Heater delivers solid value at its price point.
