## Description

desertcart.com: Everlasting Comfort 6L Humidifiers for Bedroom, Quiet 50HR Runtime No-Filter Supersized Cool Mist Humidifier Large Room for Whole House, Plants, Baby Nursery, Allergies, Dry Skin, Congestion, Indoor : Home & Kitchen

Review: Quiet, great mist stream and no daily refills - The humidifier is quiet and the water lasts a couple of days if you don’t have the setting on max. It puts out a longer and larger spray mist and it also has a duel directional mist option while other units typically only have one. You must use distilled water otherwise the spray will have white particles that collect in the vicinity of the unit. Happy with the unit in the short time we have been using it. The only negative is we wish it was top filled rather than having to remove the water tank and fill from the bottom but that’s not a game changer for us.
Review: Great customer service - I have had this humidifier 5 years. This winter I lost the fill cap on the bottom of the unit. I contacted the company and they quickly sent a replacement. This is a very good humidifier. It is quiet and works very well. I appreciate this company too.

### ⭐⭐⭐⭐⭐ Great customer service
*by A***R on February 18, 2026*

I have had this humidifier 5 years. This winter I lost the fill cap on the bottom of the unit. I contacted the company and they quickly sent a replacement. This is a very good humidifier. It is quiet and works very well. I appreciate this company too.

### ⭐⭐⭐⭐ Great unit !! 2 directional mists, not just 1, that can be changed !
*by T***E on December 31, 2025*

I love the ability to move the mist in two different directions of the room. Most only have one spray mist that can’t be changed. This one can go in 2 directions at the same time. Each can be moved in a full circle. This unit is attractive, very lightweight, easy to use, and quiet. You can’t even hear it running. Bonuses : a night light option and an essential oil tray if you want to use oils.
