How to choose

The HOLMES, BEYOND BREEZE and shinic offer reversible airflow for intake, exhaust or air exchange. The BEYOND BREEZE adds Cool, Circulate and Exhaust modes, while the shinic adjusts its dual heads for dual cooling, dual exhaust, or intake and exhaust together. The COMFORT ZONE runs 1, 2 or 3 fans at once for tailored airflow. Match airflow direction to whether you want fresh air in or stale air out.
Controls and noise
Controls differ: the BEYOND BREEZE adjusts from a distance, the COMFORT ZONE uses a manual dial, the shinic uses a knob, and the HOLMES uses push-button controls. Noise differs too: the shinic lists 38 dB and the COMFORT ZONE lists 53 dB. Match controls to how you adjust the fan, and noise to the room you cool.
