Some rooms never get a breeze no matter how many windows you open. This 7.5-inch through-wall fan solves that by mounting directly between two rooms, fitting wall thicknesses from 3.5 to 6.3 inches in a bedroom, bathroom, garage, or laundry room. Once installed, it moves up to 305 CFM at 1750 RPM to exchange stale air fast, and the two-way airflow adjustment switches between pulling air in or pushing it out depending on the season. Ten speed settings and a temperature range from 14 to 212 degrees Fahrenheit give fine control, while the smart display shows the current mode, temperature, and speed at a glance. A remote handles airflow direction, temperature, and speed from across the room, with built-in cooling, heating, sleep, and lock modes. Finished in white with ABS plastic panels around a steel vent pipe, it runs quietly at 46dB or below in a kitchen, living room, or workshop.
