Exceptionally with its competitor, again, the Alen BreatheSmart gives you wonderful and extraordinary air purifier design. There are 14 incredible color and texture options that you can choose to suit your bedroom style. Basically, it has pure white color in the cover design, and you can change it to suit your own personality by adding some bucks.

Low Noise Operation

As with its very silent operation in Eco mode, this excellent air purifier will let you forget that you own it. But, when the fan reaches its turbo speed, it will hit up to 56 dB, nearly like the sound of a medium fan. I

t is quite noisy than another air purifier such as Coway or QuietPure Whisper.  In order to make a more silent, you can set it up into “sleep mode”.Then it will work unnotified, as it just reaches maximum 41.5 dB in this mode.

Energy Efficiency

An Energy Star certification in an electronic product becomes a guarantee for efficiency and Eco-friendly. Surely it represents an energy efficient product that consumes less energy than another product. As the result, less electricity bill and less maintenance that you can get.

As an Energy Star certified product, Alen BreatheSmart will save your money too. It just consumes 105 watts on highest speed, and less on medium and sleep mode. If compared with Coway AP-1512HH in energy wattage, it is likely more wasteful.

However, if you fairly compare of each engine power and area coverage, you will find that Alen BreatheSmart is more energy efficient. Although it consumes 50% more energy than Coway, Alen BreatheSmart covers more than 3 times larger area.


The price of $599 is very expensive if compared with another air purifiers in its class such as QuietPure Whisper Air Purifiers and Coway AP-1512HH. But you will have a limited lifetime warranty. That means as long as you own the air purifier, Alen will replace or repair it for free. Of course with the terms and condition apply.

Meanwhile, another product competitors just offer 1-3 years warranty. Sounds like a good deal isn’t it?
