This DREO tower carries the lowest noise figure in the lineup, as low as 25dB, achieved with what the listing calls a new airflow design. Twenty-five decibels is in the range of a quiet library, so even with an allowance for the usual caveats it points to a fan that is intended to disappear into background noise.
The key caveat is the phrase as low as. A figure like that is almost certainly for the lowest fan speed, and the same heater at full output will make more sound. The airflow rating of 11.5 ft/s is the other half of the story: moving more air makes more noise, so the heater is quiet because it is tuned for gentle delivery, not because it is weak.
For sleepers, the practical use is to set a thermostat target and let the heater idle at its quiet step. Dust on the blades can raise noise over time, so vacuum the grille each season, and keep the tower on a hard floor so it does not buzz against a rug. If a quiet 25dB figure matters to you, this is the one to read first. Light sleepers also react to changes in sound more than to steady sound, so the click of a thermostat relay switching on and off can bother you more than a constant low hum. If you notice it, set the target a degree or two lower so that cycling is less frequent, or run the heater on its lowest step so the element simply holds the room instead of swinging between on and off.
