# FOHERE JS2420 18L Top-Fill Ultrasonic Humidifier

The FOHERE JS2420 is an 18-liter top-fill ultrasonic humidifier listed for rooms up to 1,500 square feet. Its large reservoir, caster wheels, humidity modes and adjustable mist output are aimed at users who want fewer refills and controls for larger spaces, though the stated runtime and coverage are manufacturer claims rather than independently verified results.

## At a glance

- The top-fill design is described as allowing water to be poured in from above. The listing also describes a removable tank-fill option.
- Three ultrasonic atomizers and five adjustable mist levels are claimed, with a stated output of 1300ml/H.
- Custom humidity, auto and sleep modes are listed. The description says custom mode allows a target, while auto mode adjusts output based on sensed humidity.
- The listing describes a 24-hour timer, a night light and an essential oil tray.
- Caster wheels are claimed to help move the unit to a sink for refilling.
- The product listing gives a 60-hour maximum runtime and a coverage claim of up to 1,500 square feet. These are not independent performance measurements.

## Pros

- The 18-liter tank can reduce refill frequency compared with smaller-capacity models, depending on mist setting and conditions.
- Top filling and claimed caster wheels offer alternatives to lifting the full reservoir for refills.
- Multiple mist levels and humidity modes provide more adjustment than a single-output humidifier.
- The included remote control provides a stated control option in addition to touch controls.

## Before you buy

- Several performance and operating details are not fully consistent: the product highlights describe auto mode maintaining 50–70% humidity, while the detailed instructions say it adjusts around 70%. The listed runtime, 1,500-square-foot coverage, 1300ml/H output, quietness and energy-use claims are manufacturer statements without independent confirmation. The listing also warns that a water pump may tick in bedrooms, despite describing sleep mode as quiet. Follow the supplied cleaning guidance, including changing water every three days and cleaning core parts weekly. Mineral residue may occur with tap water, and the listing recommends purified, distilled or cooled boiled water to reduce it.

## Customer feedback

The supplied evidence contains aggregate ratings but no customer-comment summary. The ratings are uniformly five-star in this small reported sample, which is a positive signal but cannot show what customers liked, identify concerns, or establish performance such as coverage or runtime.
