Stylish, powerful air purifier with HEPA, SmartSensor tech, and WhisperMax

The Alen BreatheSmart air purifier is full of features, like an effective HEPA filtration system, SmartSensor technology that helps save energy, and WhisperMax tech, which allows you to use the purifier at night while you sleep. This is an upper-end purifier that lets you customize your personal unit, so while you pay a bit more for this, you get more choice.

HEPA filters

With HEPA, the BreatheSmart gets rid of over 99% of dangerous pollutants even at a tiny size (.3 microns). One of the cool features of this specific unit is that you can choose your HEPA filter based on what you it to accomplish. You have four options: HEPA-Pure for dust/allergens, HEPA-FreshPlus for chemicals/odor, HEPA-Silver for germs/bacteria, and HEPA-OdorCell for strong odors/smoke. All filters function at that 99.97% effectiveness.

SmartSensor Technology

Once you have your purifier up and running, you want it to be as efficient as possible. The SmartSensor technology adjusts airflow automatically when allergens like pet dander and pollen are sensed, so they are eliminated quickly. This also means the purifier’s air flow will adjust when there aren’t pollutants in the air, so you save energy.


The Alen BreatheSmart is smart and traps pollutants all while maintaining the peace and quiet of your home. The fan and air chamber are specifically designed to run as quietly as possible, even on the strongest settings, so you can keep the purifier running at night and in rooms where people sleep.



The greatest advantage to this particular purifier is how customizable it is. From the specific HEPA filter to the front panel design, you can have control over the purifier’s function and style. You can even choose a primer custom panel and have any design you’d like put on the front, so your purifier matches your decor perfectly.

Captures everything

Another plus to the BreatheSmart is that it captures everything in the air that could cause trouble. With the variety of HEPA filters, you can select the one best suited to your environment, so if you have problems with allergies, you can choose one that will specifically go after spores and pollen. This doesn’t mean that the filter only captures those, of course. You can capture dust, pet dander, smoke, and so on with all of the filters.

Great for any room

Because it’s quiet and stylish, the BreatheSmart is great for any room. This includes nurseries where sleeping babies are, so they can get a peaceful night’s rest while the purifier cleans the air. With the power to customize, you can choose the room you want the BreatheSmart in, and then design accordingly.



The big weakness with the Alen is how expensive it is. It also doesn’t necessarily come with especially unique features besides the style factor and which specific HEPA filter comes with it, so if you just want an air purifier that does everything and you don’t care what it looks like, the high price tag isn’t worth it. However, if you know you want an air purifier specifically for smoke and strong odors as opposed to pollen and that’s attractive, the Alen BreatheSmart has those features.

Overall Review

Overall, the Alen BreatheSmart HEPA air purifier is a very effective, beautiful unit that you can customize for specific air quality problems as well as style. It’s very quiet and is ideal for any room, even bedrooms and nurseries. With the HEPA, nearly 100% of allergens and dust are captured, so the air quality you get is crystal-clear.
