Pistil White 250 ml aroma diffuser combines the functionality of an ultrasonic diffuser with the form of decorative ceramics. Its full, harmonious silhouette, inspired by the shape of a bud, and regular vertical fluting give it a sculptural character. The warm white color and subtle ring of light at the base bring peace, softness, and elegance to the interior.
Pistil White – 250 ml ceramic ultrasonic diffuser
Pistil White was designed as a functional element of a modern interior. The generous reservoir allows for up to 11 hours of continuous operation or even 22 hours of intermittent diffusion, meaning the device does not require frequent water refills.
The ceramic cover features a full, slightly bulbous form that tapers upwards and ends with a small cool mist outlet. Delicate vertical fluting across the entire surface visually slims the body and emphasizes its nature-inspired character. Its sculptural silhouette, inspired by the pistil and an opening flower bud, highlights the organic nature of the design.

Materials
Ceramic – top cover
The cover is made of ceramic in a warm white shade. Its glazed surface subtly reflects light, and the regular vertical fluting reveals subtly beige lines that emphasize the structure and artisanal character of the form.
Base
The low white base remains almost invisible, allowing the ceramic body to take center stage. The LED ring located at the base creates a delicate glow and visually lifts the diffuser above the furniture surface.
Design and purpose
Pistil White is perfect for:
- living room
- bedroom
- home office
- relaxation area
- therapy room
- beauty salon or spa
Its curved silhouette and calm color palette suit modern, minimalist, organic interiors, and those maintained in a soft minimalism aesthetic. Thanks to its ceramic casing, the device does not resemble typical electronic equipment – it looks like a decorative object or a small sculptural form.
Functionality
Ultrasonic technology disperses a mixture of water and essential oil in the form of a delicate, cool mist. The process occurs without heating, so the oils are not exposed to high temperatures.
Three timer settings allow you to adjust the device's operation to your daily rhythm. A shorter program is suitable for rest or an evening ritual, while a longer setting can accompany work and daily activities. Intermittent mode extends operating time up to 22 hours and allows for more economical use of the prepared mixture.
The seven-color LED backlight allows you to match the light to the interior design and mood. The delicate glow focused at the base does not dominate the space but subtly emphasizes the ceramic form of the diffuser.

Worth knowing before use
How to clean and maintain a diffuser?
According to the manufacturer's recommendations, to ensure optimal performance of the diffuser:
- Clean the tank after each use.
- Once a week, rinse the inside thoroughly with warm water (max 40°C) and a mild detergent.
- Do not use harsh cleaners or acidic detergents.
- Be careful not to let water get into the ventilation holes.
- If the ventilation system is accidentally flooded, wait 6 hours before using it again.
Tips for using your diffuser
- Always place the diffuser on a stable, flat surface.
- Fill the tank with water below the maximum level (MAX).
- Add 3–5 drops in a diffuser per 30 m² room.
- Place the ceramic lid on gently to avoid damaging it.
- Plug the power adapter into the socket and then turn on the device.
- The power button activates the mist and LED backlight.
- The light button allows you to choose one of 7 colors or turn off the backlight completely.
Diffuser operating modes:
- When you press the first button, the continuous mist starts.
- Pressing the button a second time turns on the intermittent mist - I particularly recommend this function because it ensures a gentler, longer diffusion.
- The second button allows you to turn on or change the backlight color, or leave the diffuser without light.
Additional recommendations
- Use soft water or bottled water – distilled water is not recommended.
- Always unplug the diffuser after use.
- Essential oils may cause discoloration – if they come into contact with the housing, wipe the surface immediately.
- Take care of your diffuser – with proper care, it will retain its beautiful appearance for longer.
Does the diffuser need regular cleaning?
Yes. Regular cleaning helps maintain the proper operation of the device and the intensity of diffusion. In ultrasonic diffusers, mineral deposits from water are most commonly accumulated, while in nebulizing diffusers, oil residue builds up in the nozzle. With regular use, it is advisable to clean the diffuser every 1–2 weeks or according to the manufacturer's instructions.
Why might a diffuser smell less over time?
The most common causes are mineral deposits on the ultrasonic membrane, too much essential oil in the water, dried oil residue, or using thick, resinous, or low-quality oils. In most cases, a thorough cleaning of the device and using the appropriate amount of essential oil recommended by the manufacturer will suffice.

What kind of water is best to use in an ultrasonic diffuser?
It is best to use the water recommended in the instructions for the specific model. In many cases, boiled, filtered, or bottled still water works well because it reduces scale formation on the membrane. Demineralized water can further reduce mineral deposits, but it should only be used if permitted by the device manufacturer.
