Now, let’s begin by looking at the features!

Let’s start with the design and aesthetic. In terms of the design, it’s very sleek and intuitive. You won’t have any problems figuring out how to use this air purifier. Nor will you have any aversion putting it in your home. It also comes in a variety of different colors.

The MAC – Maximum Area Coverage – of the Alen BreatheSmart 75i is 1,300 square feet. Due to the airflow technology that is being used, it can completely purify the air in that space in just 30 minutes, and it can continue doing this throughout the entirety of the day.

One of the great things about the design is that it uses WhisperMax technology. This technology is designed to keep the air purifier “quiet”, so that you can use it throughout the day – even while sleeping – without having to deal with any disruptions or disturbances. According to Alen, it runs twice as quiet as other air purifiers in its class.

Using laser technology, the Alen BreatheSmart 75i is able to detect the quality of the air, at any given time. These lasers detect the smallest and most minuscule of particles, and then this information is fed back into the air purifier. On an LED screen, you’re able to see the quality of your air, based on this information. And, you don’t even need to manually adjust the settings, to accommodate your current air quality, because the air purifier does that for you.

You can use the Alen BreatheSmart 75i to get rid of many different types of contaminants:
– Allergens
– Dust
– Bacteria
– Mold
– Chemicals

As well as odors, such as those caused by smoking, cooking, or even your pets.

This is all accomplished through the use of a True-HEPA filter that easily captures the smallest of particles, breaking them up and then removing them from your air. This filter is also coated with something known as an “antimicrobial layer”. What this does is it prevents the particles that go through the filter from producing more fungi, or more bacteria.

There is also an activated carbon filter. This filter absorbs various airborne particles. Most of which comprise odors. So, if you live in a home that constantly has various odors and stenches running through it, this is a very useful filter to have.

Finally, the last notable feature is that the Alen BreatheSmart 75i comes with what’s known as the “Alen Forever Guarantee.” This means that this product has a warranty that NEVER expires. Whenever you have a problem, send it back, and they’ll fix it for you/replace the air purifier.

What Are The Pros Of This Air Purifier?

The design is incredibly simplistic and easy to understand. You won’t have any problems figuring out how to use this air purifier.

Aesthetically, it looks great. Most air purifiers look a bit ugly or bland. Instead, the Alen BreatheSmart 75i has a wonderful aesthetic and offers many different choices for colors.

You can purify a very large space – up to 1,300 square-feet – using this air purifier. This gives you a lot of flexibility, especially if you have a smaller space.

It’s a quiet air purifier. Never making too much noise and disrupting the day’s activities or when you want to sleep or relax.

Due to the laser technology, the sensors are incredibly accurate and efficient. They can adjust the settings of the air purifier at any given time, ensuring that you don’t even need to adjust the air purification settings manually.

This is a very powerful air purifier. You can remove many different types of particles with it. Whether you have allergies and want to get rid of allergens, or your home is very smelly, this air purifier can help.

The filtration is incredibly efficient and powerful at doing the above.

With the “Forever Warranty”, you won’t ever have to worry if you accidentally damage/break this air purifier.

What Are The Cons Of This Air Purifier?

It’s expensive. But, you are paying for the quality, which is exceptional.


If you want one the best air purifiers on the market, and don’t mind spending some cash, then the Alen BreatheSmart 75i is a fantastic choice!
