I chose this one due to no filter but despite cleaning with soap every 2-3 days and using vinegar as suggested in the periodic maintenance, it continues to show signs of pink mold.

I am blown away by this humidifier! I have owned several in the past 5 years and this one takes the cake! Easy to use, great mist out put and no filter needed!

We had the humidifier plugged in and used distilled water, but it still grew mold in the tank and in the base. It is also too bright for a child's/infant's room.

Without a doubt this is our best humidifier so far. As a busy momma I have tons of to do's daily and having one less thing to clean helps so much. 100% recommend this humidifier.

I love the idea of not having to clean this so often. I bought 2 of them to put in each of my boy's rooms. It's way too bright so I end up having to unplug it during the night and then plug back in during the day which defeats the purpose.

We love the easy function of this product. Being a mom to a toddler and twins - it's essential to ensure the products I use provide them with the best quality. I feel that this truly does that for us. It always makes things so much easier as a mama.

The humidifier has its cons and pros. I find it does stay cleaner longer, but a pink/red film is also forming. The strength of humidity output is impressive.

We've had an extremely dry winter & this humidifier has been such a great help in keeping my toddler comfortable when sleeping. We love that there aren't any filters to change & the LED lights doubling as a night light is a great feature.

Bought this for our newborn's room and within weeks of use there was mold in the bottom of the container. Very difficult to clean as well. Might work in a lab setting but does not work in real life.

As a mom of 3 I've tested a bunch of humidifiers and this ONE is the THE ONE! Great size fits on a nightstand or changing table perfectly and the LED lights help to keep it clean and free of mold and other bacteria!! It's perfect!
