Bought this sterilization air purifier after having a very long string of awful colds run through the family and want to try my best to avoid them! So far so good, my boys love turning it on and call it ‘the rocket ship’ because the mist goes up so high haha. I love how big the water tank is so it can run all day. Only thing is I wish it would incorporate essential oils more, the little drawer at the back allows you to put some drops onto a pad but I can’t smell much of the aroma come out on the normal mist mode. Other than that we love it and it’s now become a staple of our house!
