This little guy rocks! Would buy again, clean up is a breeze and you can actually feel the difference in the air after about 30 mins when it’s on full blast. If you keep it at that setting you’ll have to refill it quick so I leave it on low to medium and only have to refill every other day (depending on weather) but I sleep with mine on and wake up with water still in the tank. Also, this is practically silent. I have insomnia and take sleeping meds and sometimes use ear plugs and this is quieter than my dogs breathing so if you’re noise sensitive I can’t imagine you’d have a hard time with this product at all.
