## At a glance

- Top-fill design is described for pouring water directly into the unit.
- The manufacturer claims up to 60 hours per fill when using the lowest mist setting.
- Three mist levels and a 360° nozzle are listed, with stated coverage of 600 square feet.
- App, remote, and touch controls are listed. The feature text specifies Tuya app use over 2.4GHz Wi-Fi.
- Sleep mode, adjustable humidity control, timer, night light, low-water indicator, and auto shutoff are claimed.

## Pros

- The 10-liter capacity and stated low-setting runtime can reduce refill frequency compared with smaller-capacity units.
- Top filling avoids needing to carry the tank to a separate sink for routine refills.
- App, remote, and touch controls give several ways to adjust operation.

## Cons

- The stated 60-hour runtime applies only to the lowest mist setting, so higher output may require more frequent refills.

## Before you buy

- Listing details are inconsistent or unconfirmed: the title says 2.64 gallons, the specifications give 10 liters, and listed dimensions are 7.48"D x 7.48"W x 25"H while feature copy gives 7.87" × 7.87" × 26.18". The title and listing describe quiet operation at 35dB, while the feature text also claims 300mL/h output, a 24-hour timer, and 40%–90% humidity adjustment. App control is listed, but the feature copy specifies Tuya and 2.4GHz Wi-Fi. Confirm the exact configuration and operating details for the selected listing.

## In the box

- Humidifier (Included)
- Remote (Included)
- Manual (Included)
- Quick-start guide (Included)

## A good fit for

- Buyers who want a large-capacity humidifier with a top-fill design and multiple control methods.
- People considering use in a bedroom or a space for which the claimed 600-square-foot coverage is appropriate.

## Less suited to

- Buyers who need a guaranteed runtime at higher mist settings or independently confirmed coverage.
- Buyers who need dimensions confirmed before reserving a specific space.

## Customer feedback

Aggregate ratings skew positive, with most ratings in the five-star category, but the sample is limited and does not explain customers' reasons. This offers a modest indication of buyer satisfaction, not evidence that the claimed runtime, noise level, or coverage will match a particular room or use pattern.

## Frequently asked questions

### How long does the humidifier run per fill?
The listing claims up to 60 hours on the lowest mist setting. It does not establish the runtime at higher settings.
### What controls does it offer?
App, remote, and touch controls are listed. The feature copy names the Tuya app and 2.4GHz Wi-Fi, but confirm those details for the selected listing.
### How much space is it claimed to cover?
The listed coverage is 600 square feet. Treat that as a manufacturer claim rather than a verified room-performance result.
### What is included in the package?
The listed components are the humidifier, remote, manual, and quick-start guide.
