Stadler Form Karl Top Fill Wi-Fi Enabled Humidifier

Product Overview

The Stadler Form Karl humidifiers use less power making them more efficient to operation. These Reddot 2023 design award winners have a unique top-fill feature which allows them to be re-filled as the water begins to run low, without waiting for them to run dry.

Wi-Fi enabled, you can control both the Karl and the Karl Big humidifiers via the Smartphone App, setting the desired humidity level, fan speed, and LED light level.

Evaporative Humidification

These effective humidifiers from Stadler Form use wick filters and evaporation to add soothing moisture to dry, winter air. This type of humidifier takes a bit longer than a vaporizer or mist-type, pulling dry air in and through saturated filters, before expelling the hydrated air into the room.

• Karl Humidifier: Provides moisturized air for areas up to 1,076 square feet.
• Karl Big Humidifier: Provides moisturized air for areas up to 1,615 square feet.

The white LED underneath the filter change button will flash. After changing the filters, press and hold the reset button until the LED is illuminated without flashing.

Unique Design

Designed to pull dry air in from both sides of the unit using an internal fan, the Karl humidifiers feature a soft gray exterior that fits well into any décor. Easily fill by lifting off the upper part to fill the lower part with clean, cold tap water up to the maximum mark. This can be done directly from the tap or by using a clean water can to fill it via the opening for refilling.

This design allows you to top up the water level in the humidifier while it’s operating. A very handy option, should you need to run out for an hour or two to run errands.  Simply use the opening for refilling on the top of the device by pressing on the opening. Then use a watering can or bottle without having to turn it off.

Perfect Control

The controls for the Karl humidifiers are located on the inside rim of the top. These include power on/off, humidity level, fan speed, LED control, Wi-Fi function, and water & filter reminders.

• Hydrostat: Set the desired humidity level at 40% RH, 50% RH, 55% RH, or for Constant Operation.
• Fan Speed: Select a fan speed from 1-3, and Turbo. Level 2 is the default setting, and Turbo is a good choice when first setting up the unit for operation.
• Auto Mode: In this mode, the unit automatically maintains the desired humidity level, but cannot be used when it is set to Constant Operation. Set the desired level, then press Auto, and the fan speed will be adjusted to maintain the RH setting.
• LEDs: If the lights are too bright—especially at night—you can reduce the brightness by pressing the dimmer button. Select Normal (default level), Dimmed, or Lights-Out
