I bought this three weeks ago for my master bedroom, which does not have heat. When on cool setting, it functions pretty much like the TP04, which I have in my living room. It hasn’t been cold enough yet to rate the heating effectiveness, but the heating seems to be better than other space heaters. The air purifier function seems to be excellent, and the app that comes with it provides great information on what it is sensing. However, no matter what the setting, this model has a constant low-pitched whirring sound, even when the fan is not on. This is in contrast to the TP04 that is completely silent except when the fan is on a high setting. So this is not a good choice for a bedroom unless you are not bothered by constant low-level noise that is not the same as “white” noise.
