Great warm mist humidifier, need some cleaning

Great warm mist humidifier, keep the room pretty good humidity against HVAC dry heating air. Needs a little bit of maintenance/cleaning to keep it fresh, but overall I'm super satisfied with how well it works.

Super user friendly, effective, quiet humidifier.

[This review was collected as part of a promotion.] Having a 4-year-old who often gets sick, this product was perfect for those stuffy and congested nights! This Honeywell humidifier was super easy to set up and the instructions are simple. There is an essential oil cup to add any oils you want to evaporate. It's an all-in-one relief for my little one. It has an Easy top fill which makes use and clean up super simple. Would definitely recommend. Its also super quiet and went unnoticed throughout the night. Thank you @influenster for the complimentary humidifier.

Easy set up

[This review was collected as part of a promotion.] Super easy set up. This is lightweight but so easy to fill with water. I love the spot for essential oils should you like that option. There are 2 options. It is a little noisier when running than others it is much quieter on the left option. This is very easy to clean on the outside and doesn't seem to look as dusty as some ones with a shiny finish on the outside.
