Right off the bat, you’re going to notice that this air purifier has an exceptionally sleek and minimalist design. Every little design feature and element looks nice, and there is nothing that feels unnecessary or extraneous about the design. Plus, you can purchase this air purifier in a variety of different colors, and each color goes very well with the design of this air purifier.

Using this air purifier you are able to cover a space that is no more than 700 square-feet. If you place this air purifier in a space that is larger than 700 square-feet, it will only be able to purify 700 square-feet of that space. But, fortunately, this air purifier is only fifteen-pounds, so it’s fairly easy for you to move the air purifier from space to space, so that it can purify larger areas.

On the top of the air purifier, there is a control panel that consists of various buttons and settings. This is the control panel that you’ll be using to access all of the features and settings that this air purifier offers.

In the middle of the control panel, there is the power button. All around this power button, there is a circle. This circle changes colors depending on the current air quality of the space that the air purifier is located in. One of the coolest features of this air purifier is the fact that it’s able to detect the current air quality, and then it tells you this air quality. That way, you always know what settings are ideal for the current situation.

To the left of the power button, there is a button that allows you to set the timer, and an indicator that shows you the current status of the filter, and if you need to replace it. Using the timer, you are able to set the air purifier to run for two-hours, four-hours, or twelve-hours. Then, when the time is up, the air purifier will shut off. This conserves energy, and allows you to focus on other tasks, without worrying about how long the air purifier is running for.

To the right of the power button, there is a button that allows you to choose from four different air purification speeds, as well as a button that allows you to lock the air purifier’s current settings.

Having access to four different speeds is very nice, because that allows you to control how fast the air purifier is. If you want the air purifier to run slowly, and quietly, then you can select the first speed. But, if the air quality is really bad, then one of the higher speeds is ideal. But, at the lowest speed, the air purifier makes very little noise, due to WhisperMax Technology, which makes it easy for you to sleep with the air purifier on.

Without the proper filtration technologies, an air purifier isn’t very useful, even if the overall design is quite good. What makes this air purifier great is the fact that it has an excellent design, while also offering the proper filtration technologies.

This air purifier uses a very powerful True-HEPA Filter. What this True-HEPA Filter does, is it removes all of the dust, fur, and allergens that flow into the machine. This is because the system consists of several different HEPA-Layers, all of which serve as mechanisms for removing those particles from the air, and ensuring that the air that comes out of the air purifier is nice and clean.

Overall, this is an excellent air purifier. But, it does cost a decent amount of money, due to the quality of the design, the features that this air purifier offers, as well as the performance and efficiency that it gives you.

For that reason, this air purifier is ideal for people who aren’t afraid to spend some money, in order to receive the best possible product. But, if that’s not what you need, then another air purifier may be better for you.
