Cool, high output
The big-tank value — 6 liters for 50-hour runs with an essential-oil tray, humidifier and diffuser in one budget box.
Everlasting Comfort bundles two nightstand gadgets: a 6-liter cool-mist humidifier (up to 50 hours) WITH a built-in essential-oil tray, so it perfumes as it humidifies. Quiet operation, high mist output for large rooms, auto-shutoff. It's the value answer to the Levoit's tank size, minus the smart controls — a big, simple, dual-purpose unit for people who want humidity and aroma without two devices.

Frequently asked questions
Humidifier and diffuser in one — any catch?
The oil tray scents lightly via the mist — pleasant but subtler than a dedicated diffuser. For strong aroma keep a separate diffuser; for light background scent this saves a device and an outlet.
6L vs Levoit's 6L?
Same tank size and runtime; Levoit adds warm mist and app control for more money. Everlasting is the manual value version.
Coverage?
Large — high mist output handles big bedrooms and open-plan spaces the 1.5L units can't.
Cleaning the oil tray?
Wipe it with the weekly clean so old oil doesn't turn rancid — a small extra step for the combo feature.
