One of the most notable and useful features of this Air Purifier is the fact that it can clean a total of 1,100 square-feet, in just half an hour. In that amount of time, you can clean an incredibly large space. The main reason for this incredible level of efficiency is because Alen works with NASA airflow engineers, so the technology is far more advanced and precise than other Air Purifiers.

Using a technology known as “WhisperMax”, this air purifier makes very little noise. Even when running on its highest purification setting, it still produces very little noise. The noise that it does produce is similar to the noise produced by a white noise machine, and as such, it is very relaxing, and even conducive to good sleep.

Alen has given the BreatheSmart Classic Large Room Air Purifier something known as the “Laser Smart Sensor”. Now, essentially, the Laser Smart Sensor is a type of laser technology that is used to sense the particles that are in your room. It can sense particles that are as small as 0.3 microns, and then the data that these lasers gather is then sent to the air purifier. You can find this information reflected in the Air Quality Indicator Light, which is a small light that tells you just how clean, or how dirty, your air actually is.

Multiple fan speeds exist, each one designed to accommodate a certain level of air quality. For especially dirty air, you’re going to need a higher fan speed. For air that isn’t very dirty, a lower fan speed will suffice. However, you don’t have to adjust the speed of the fan manually. Instead, using “Auto-Mode” the air purifier looks at your air quality, and adjusts itself to accommodate the quality of your air.

The Alen BreatheSmart Classic Large Room Air Purifier uses a HEPA-Filter. This is a powerful HEPA-Filter that Alen has had a big hand in designing, and it is incredibly useful and efficient.

Using this HEPA-Filter, the air purifier is able to suck in, and eliminate, things like dust, pet dander, all kinds of allergens, germs, as well as odors.

Nasty smells are eliminated through the use of a technology known as HEPA-OdorCell, which Alen has developed. This technology is designed to filter odors, and then to break them down at the molecular level, which destroys whatever smells are in your home, ensuring that these odors don’t simply dissipate or come back.

According to Alen, HEPA-OdorCell technology works incredibly well with odors from cat litter, diaper smells, along with other types of pet debris. In fact, it’s specialty is pet debris, due to the nature of the technology and how it works.

One of the other notable features that Alen has given this air purifier is the design. More specifically, this is an exceptionally well-designed, and very attractive, air purifier. Clarity is one of the defining features of this device, and that is seen in the simple and sleek design and aesthetic, the clearly marked and labeled buttons and indicators.

Alen BreatheSmart Classic

At the end of the day, the Alen BreatheSmart Classic Large Room Air Purifier is an absolutely incredible air purifier that will do wonders to the quality of your air, and to your health, as well, due to the efficiency in which it filters and purifiers the particles in your air.

You must know, however, that this is definitely a “premium” air purifier, and as such, it is quite a bit more expensive than other air purifiers on the market.
