Alen BreatheSmart 45i HEPA Air Purifier Review

Air purifiers are incredibly useful devices. More often than not, our air is full of nasty germs and contaminants that, when we inhale them, affect our bodies in less than positive ways especially if we’re inhaling them over a longer period, such as throughout the day.

But, with a good air purifier, the air is sucked in, and then all of the nasty germs and contaminants are removed from the air, and then the air is sent back out, allowing you to inhale it without having to worry about any potential side effects, and other nastiness.

Over the years, air purifiers have become increasingly more advanced and elaborate.

The technology has grown and transformed a lot, and now, air purifiers are exceptionally advanced and useful machines that have developed a variety of processes that enable them to thoroughly and effectively cleanse your air of whatever impurities are in your air.

Today, one of the most advanced and useful air purifiers is the Alen BreatheSmart 45i Air Purifier. Now, as air purifier manufacturers go, Alen is easily one of the greatest manufacturers. They have developed many amazing air purifiers.

Air purifiers that are, from a design and aesthetic standpoint, absolutely beautiful, while also coming with all of the features that enable you to clean your air in a truly efficient and easy manner.

We’re going to be taking an in-depth look at the Alen BreatheSmart 45i Air Purifier today. You’re going to learn all about the unique features and attributes that comprise this excellent air purifier.

Features

Let’s start off with the design. Alen has opted for a sleek and minimalist design. You can choose from fourteen different designer panels, and these designer panels are all primary colors that are designed to go with just about anything. As for the shape, it is a rectangular shape, and everything is stored within a nice, sleek rectangular frame.

In comparison to other air purifiers, the Alen BreatheSmart 45i is quite light, since it only weighs around 20 pounds. Picking it up and moving it around is easy, as a result of this.

With the design, you can place the Alen BreatheSmart 45i just about anywhere, and it will blend in with that space, and it might even make that space look extra nice, as well. Most air purifiers don’t have this level of aesthetic quality, which makes this air purifier rather unique.

To aid in the overall design quality, everything is very clearly labeled and delineated. You won’t ever be confused or uncertain about what the buttons do, or how to activate certain features. Instead, clarity is one of the main design themes that runs throughout this air purifier.

Alen has designed this air purifier to be used in smaller spaces, as well as larger spaces, as long as they aren’t too big. More specifically, the Maximum Area Coverage – or “MAC”, for short – is 800 square feet.

This is a pretty decent size, for an air purifier. You can use this unit in most apartments – especially studio apartments – and you shouldn’t have any issues using it in living rooms, basements, attics, and, of course, bedrooms.

If you intend to use the device in your bedroom, while sleeping, you don’t need to worry about the air purifier being too loud or noisy. The Alen BreatheSmart 45i Air Purifier uses a technology known as “WhisperMax”.

WhisperMax is a technology that reduces the sound of the filtration systems, as they work so that less sound is produced. That way, you will be able to sleep, without hearing a constant throbbing or pulsing sound, which is the sound that many air purifiers produce.

Ultimately, the WhisperMax feature is designed for convenience and ease-of-use. Making it more convenient to use while sleeping, and making it easier to use the air purifier, in general. Another feature that has been designed to aid in the overall convenience and ease-of-use is that of the laser-technology that is used for the sensors.

Using something known as a “Laser Smart Sensor”, lasers are used to sense the smallest and most minuscule particles that are in your air, at any given time. These laser sensors can detect particles that are as small as 0.3 microns – which is 300-times as small as a single strand of hair – and then this information is fed back into the air purifier.

Using this information, the air purifier can determine the quality of your air, and then it adjusts the speed of the air purifier, and the overall filtration process, to best accommodate your air quality.

You can access this information, regarding the quality of your air, at any time, by looking at the small LED color display, that is on the air purifier.

The filtration system is that of a HEPA-PURE system, which involves numerous HEPA layers, that are designed to break up the small particles – such as allergens and dust particles – that are in your air.

Initially, the first filter that is used is that of a Pre-Filter, which breaks up all of the bigger particles, and separates them from each other, making it easier for everything to then flow into the main HEPA-Filter layers, where all of the other particles are broken up and separated. After that, the air is released, and it is now healthy and clean, making it safe for you to breathe.

If you have a large space you want to remove irritants from, We recommend the Airmega 400. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them.
The Levoit Vista 200 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.
With high end air cleaning performance and a whisper quiet fan, the Winix 5300-2 is the perfect combination of power and finesse. It cleared airborne particulates out of our smokey testing room faster than any other model.
