Simple & Sleek Design

Right away, when you first take this humidifier out of the packaging you’ll notice that it’s quite small, and that the design is simple and very sleek. Each button and feature is outlined and delineated with precision, and figuring out how to set-up and use this humidifier is effortless.

Much of the ease that this humidifier offers comes from the fact that it doesn’t offer many features or settings. Instead, you’ll only be using one button, and that button is the power button. All you need to do to use this humidifier is to pour water into the water tank, make sure the humidifier is plugged in, and then press the power-button. It’s that simple!

Excellent For Small Rooms

Since this is a small and lightweight humidifier, it isn’t designed for large, open spaces. If you have a large living room that needs some extra humidity – to name just one example – this isn’t the humidifier for you.

If you have a bedroom or a small office that needs to be humidified, though, then this humidifier will serve that purpose very well. This humidifier has been designed for humidifying spaces that are no more than 210 square-feet.

All of the humidification is accomplished using a water tank that holds .21-gallons of water. All of the water in that water tank is converted into humidity through the use of ultrasonic technology – we’ll dive into that in just a moment – and it’s capable of spreading throughout the entirety of a 210 square-foot space. But, what’s really nice is that when the tank is full, it can run for fourteen-hours, completely uninterrupted.

Uses Ultrasonic Technology

Through the use of ultrasonic technology, this humidifier is able to take the water that you pour into the water tank, and turn it into pure humidity. Most humidifiers use a fan to perform this function, this humidifier uses ultrasonic technology which makes far less noise.

Ultrasonic technology is a technology that involves creating ultrasonic sound waves. These are very quiet sound waves that, while quiet, are incredibly strong. These sound waves are so strong that they break down all of the water that’s in the water tank, and they turn that water into individual droplets which flow out of the humidifier.

In breaking down the water into individual droplets, the water turns into a nice, cool mist. All of this humidity flows out of the humidifier, through an opening at the top, and this allows the entirety of your space to be filled with cool mist humidity.

Very Useful Features

To make the humidification process even easier, Pure Guardian has given this humidifier a couple of distinct features. These features, while small and quite simple, make the entirety of the humidification experience much easier. Without these features, this humidifier wouldn’t be as effective as it is.

One of the most important features this humidifier uses is that of the directional mist nozzle. This directional mist nozzle is on the top of the humidifier, and it’s attached to the opening where humidity comes out of.

With the directional mist nozzle, you are able to adjust the direction that humidity comes out of. This is extremely useful, because if there is a certain space in a room that needs some extra humidity, then you can use the directional mist nozzle to shoot humidity into that part of the space.

Along with that, two other very notable features are the fact that this humidifier shuts off when the water tank is empty, and that an indicator light turns on when the water tank is nearly empty. These are simple, but they make it easier to tell when you need to refill the tank.

Perhaps the most useful feature, though, is the overall simplicity this humidifier offers. Using this humidifier is very easy, since it consists of very few components or buttons. This makes setting the humidifier up and humidifying your space a nearly effortless process.

Conclusion: Excellent Humidifier For Small Spaces

In the end, if you are looking for an excellent humidifier that works well in small spaces, then the Pure Guardian H910BL Ultrasonic Cool Mist Humidifier will be an excellent purchase for you. It is easily one of the simplest and most effective humidifiers on the market!
