Quick Start Guide

Step 1: Connect the power supply (only use the original power cord).

Step 2: Place on a flat, hard surface (long-pile carpets or table mats may block the air vent and stop mist output).

Step 3: Add purified water below the MAX level (too little water triggers auto shut-off; too much causes weak or no mist).

Step 4: Add essential oil drops.

Step 5: Replace the lid, press the left mist button, and enjoy instant mist.

Frequently Asked Questions & Explanations

1. What is this Onaboviva essential oil diffuser made of?

The cover is handcrafted from ceramic, and the inner water tank uses food-safe, BPA-free PP plastic. It’s crack-resistant, stands up to essential oils, and is safe for babies and pets.

2. How long can it work when fully filled with water?

With a 280ml capacity, it runs up to 12 hours on continuous mist and 24 hours on intermittent mist. It automatically shuts off when water runs out, so you can use it safely all night.

3. Why does it stop working or produce less mist after a while?

This is normal for ultrasonic diffusers. It usually happens when the nebulizer disc in the tank gets clogged with oil residue from infrequent cleaning. Just clean the tank regularly and dry it with a soft paper towel to fix it.

4. What makes Onaboviva special?

Beyond core features like cool mist, auto shut-off, and a timer, we’ve added continuous/intermittent mist and a sleep mode to make your daily routine more enjoyable.

5. How do I adjust the mist level?

There are two mist settings:

Intermittent: Mist turns on/off every 30 seconds (low output)Continuous: Steady mist (high output). Our 2.4MHz ultrasonic tech turns water and oil into fine mist. The food-grade double silicone seal and upgraded snap-lock design keep it stable in damp conditions, even if water gets into the air vent.

6. Can I use it with lavender oil before bed, even if I fall asleep?

Absolutely! It has 1/3/8 hour timers and auto-shuts off when water runs out, so you don’t have to get up. Our exclusive sleep mode turns off all lights after 30 minutes, letting you enjoy the calming aroma without any distractions.
