This ultrasonic aromatherapy device offers a focused approach to relaxation and wellbeing. Utilizing four adjustable timers, it allows you to tailor sessions for specific needs – from a quick stress relief boost to a longer, more immersive wellness experience. The core functionality centres around ultrasonic vibration, generating gentle yet effective micro-currents that stimulate acupressure points on the wrist and temples. This targeted approach is designed to promote relaxation, reduce tension, and encourage a sense of calm.
The device’s four timer settings provide flexibility in managing your aromatherapy sessions. You can select a short 15-minute burst for a quick reset during a busy day, or opt for longer durations – up to 60 minutes – for deeper relaxation. The ultrasonic technology is particularly effective when combined with essential oils, allowing you to fully harness their therapeutic properties. This device complements the use of your favourite essential oils, enhancing the overall experience and maximizing their benefits.
Designed for personal wellbeing, this unit provides a convenient way to integrate aromatherapy into your daily routine. The built-in ultrasonic generator creates a soothing vibration, while the adjustable timers ensure you can control the intensity and duration of each session. It’s a simple yet powerful tool for promoting relaxation and creating a calming atmosphere within your home. Please note that this device is designed to work with essential oils; it does not include any oils itself.

FAQ
What kind of essential oils can I use with this device?+
You can safely use most standard, 100% pure essential oils with this ultrasonic diffuser. Avoid using synthetic fragrances or heavily diluted blends, as these may not produce the same therapeutic effect and could potentially damage the unit. Citrus oils are generally considered safe for extended use.
How often should I clean the water tank?+
We recommend cleaning the water tank after every 3-5 uses to prevent bacterial build-up. Simply unplug the device, empty the remaining water, and wash the tank with warm soapy water. Rinse thoroughly and allow it to dry completely before refilling.
Does this device produce heat?+
No, this ultrasonic diffuser operates passively without generating any heat. This is important for preserving the delicate properties of essential oils which can be damaged by high temperatures.
Are the 4 timers adjustable individually?+
Yes, each of the four timer settings is independently adjustable from 15 to 60 minutes. You can set different durations for each setting to suit your specific needs and preferences.
Can I use this device with water only?+
Absolutely! You don’t need to add essential oils to experience the benefits of ultrasonic vibration. Using just water is a perfectly acceptable way to enjoy the relaxing effects.
What power source does this device require?+
This device operates on a standard UK mains electricity supply (230V) and requires an adaptor if your outlet differs. It’s not battery-operated.
Is it safe to operate near electronics?+
Due to its passive operation, the ultrasonic vibration does not interfere with nearby electronic devices. However, we recommend keeping it at least 30cm away from sensitive equipment for optimal safety.
What is the warranty on this product?+
This device comes with a standard 1-year manufacturer's warranty against defects in materials and workmanship. Please refer to Amazon UK’s terms and conditions for full details regarding warranty claims.
Can I use this device while sleeping?+
Yes, you can certainly use this device while you sleep. However, we recommend starting with shorter sessions (15-30 minutes) to gauge your sensitivity and adjust the timer accordingly. Placing a small bowl of water in front of it may help reduce noise.
Will the ultrasonic vibrations damage my skin?+
The gentle vibrations produced by this device are generally considered safe for use on the skin, particularly when combined with essential oils. However, if you experience any irritation, discontinue use and consult a healthcare professional.
