## Ultrasonic Cool Mist Technology

The Dr Trust 907 uses **ultrasonic technology** to generate a fine cool mist without heating the water.

Cool-mist operation can be particularly convenient for bedrooms, family spaces and other indoor environments because there is no hot steam outlet associated with traditional warm-mist humidifiers.

The unit should still be positioned safely on a stable, water-resistant surface and kept out of reach of children and pets.

* * *

## Large 4.5-Litre Water Tank

The large **4.5 L water reservoir** reduces the need for frequent refilling compared with smaller-capacity humidifiers.

Depending on the chosen mist output, the manufacturer states an operating duration of approximately **12 to 22 hours**.

At lower mist settings, the humidifier may operate for up to approximately 22 hours before requiring a refill.

* * *

## Adjustable Mist Output

A simple rotary knob allows the user to adjust the mist output according to room conditions and personal preference.

You can select a lower output for longer operation or increase the mist output when greater humidification is desired.

Actual runtime and room humidity will vary according to:

-   Selected mist setting
-   Room size
-   Starting humidity
-   Ventilation
-   Temperature
-   Door and window opening

* * *

## Quiet Operation – Up to Approximately 38 dB

The ultrasonic system is designed for quiet operation, with the manufacturer stating a noise level of up to approximately **38 dB** depending on the selected setting.

This makes the Dr Trust 907 suitable for environments where low operating noise is desirable, such as:

-   Bedrooms
-   Living rooms
-   Home offices
-   Study rooms
-   Nursery rooms with appropriate adult supervision and safe placement
-   Yoga or relaxation areas

* * *

## Essential Oil & Aroma Function

The Dr Trust 907 is designed to support aromatherapy use according to the manufacturer's product instructions.

This allows the humidifier to function both as a cool-mist humidifier and an aroma-diffusion device when used correctly.

**Important:** use only suitable essential oils and only in the manner specified by Dr Trust. Do not add medications, vapor rubs or other substances unless specifically permitted by the manufacturer.

* * *

## Automatic Waterless Shut-Off

The humidifier includes an **automatic shut-off function** designed to stop operation when the water tank becomes empty.

This helps prevent unnecessary dry running and makes extended operation more convenient.

* * *

## Wide Opening for Easier Refilling & Cleaning

The 4.5 L tank has a wide opening designed to make routine refilling and cleaning easier.

Regular cleaning is important with any humidifier because standing water, mineral deposits and poor maintenance can affect hygiene and mist performance.

Always follow the cleaning and maintenance instructions supplied with the appliance.

* * *

## Where Can the Dr Trust 907 Be Used?

The compact 4.5 L model can be considered for:

-   Bedrooms
