Is that an option to use frozen distilled water ? I used my machine the first time last night woke up during the night sometime with mask off i was like oops and put it back on but I felt like I was suffercating my room was hot so that didn't help.. the mask the air was warm and that made it worse so ended up taking it back off figured tonight I would turn off humidity but if there is a chance to use ice for cool air I would certinally try that ..also planning on fixing a/c can't stand being hot at nite need cold air flow 😂
