InnoGear 2nd Version Essential Oil Diffuser
No products found.
The InnoGear 2nd Version Essential Oil Diffuser is a unique but reliable type of ultrasonic essential oil diffuser that uses cool mist to disperse oils. It is a small yet straightforward diffuser that works best in small or medium-sized spaces.
Review
This is an inexpensive product that is made out of plastic and has its fair share of manufacturing issues, but the way that the manufacturer handles those problems and how most of the product holds up makes it worth the investment.
This product has three different working modes (intermittent, light only, and continuous) that you can easily switch between. While the tiny reservoir makes it hard to use this effectively in a large space, that same small size makes this compact diffuser perfect for small spaces or even for your office.
When the water is out on this model, it will automatically shut off. Since the mist produced is very fine, you will notice the scent almost immediately if you use this in a small space.
The simple design of this model is also worth mentioning. While there are seven different colored lights and a few lighting modes, changing between these modes is still easy to do. Once you check out the user manual, you’ll find that you can work with this product easily without much of a learning curve at all.

URPOWER Essential Oil Diffuser

The URPOWER Essential Oil Diffuser is an ultrasonic essential oil diffuser that can be used in small to medium-sized rooms with good effectiveness.
Review
The first thing that you are likely to notice about this diffuser is the unique design that it offers. Available in three different color palettes, the rounded edges and a unique misting portion will help it become more than just a diffuser. You could almost consider it a type of home decoration.
The water reservoir on this model is relatively small at 150 milliliters, but the diffuser can effectively humidify and scent rooms with a size of up to 215 square feet with ease. The mist on this model will run in two different modes: intermittent or continuous. Depending on what mode you choose, it can run for up to eight hours.
The light on this model only comes out of the top and bottom, so it’s not as glaringly bright as the LEDs on some models. That is nice if you want to use this while sleeping, but the color change still gives off a nice aura throughout your usage time. You can also easily adjust the color and timing of the lights, which is very convenient.
Additionally, URPOWER really wants to be sure that you like this diffuser if you purchase it. That is why the model comes with a limited one-year warranty in addition to a 100% money-back guarantee for 90 days. If you hate it, they’ll do their best to make it right ASAP, so what is there to worry about?
