The one thing that everyone should be concerned about is the air pollution problems because after all we are breathing it in and it can have serious effects on our lives.

The easiest and most likely the best solution to this problem is the Alen BreatheSmart FLEX Customizable Air Purifier with HEPA-Silver Filter. This purifier will completely change the way you think about air pollution once you try it out.

This specific type of air purifier is different in many ways from other filtration products, mostly because it is specially designed to clear the air in rooms up to 700 square feet. Everyone that has tried it at least once was immediately satisfied with the results that this product can offer. One thing that makes this unit so special from other is that it has the option to change up the filters to fit your needs. However, the most favorite type is the HEPA-Silver Filter because it is the best all-around filtration product.

We can talk a lot about all the features and the type of technology that is built in this device, but we decided to make a shorter list of the most important things that this unit can offer. Some features that you cannot find with other similar products. You will be surprised how many additional and helpful features this purifier can have. Here is that list of most impressive features.

Filtration Options

As we have mentioned this before the Alen BreatheSmart FLEX Customizable Air Purifier has various types of filters that you can choose from. Of course, all of these are HEPA filters that are providing the highest quality filtration options. The filter that you get with purchasing this purifier is the HEPA-Pure, that is the most basic one that is great for filtering all the accumulated dust and allergens from the air.

Next up is the filter that we have tested out because it was the most popular one by far, the HEPA-Silver filter and we must say it is a very good filter that is most likely the best solution for you. The Silver Filter is capable of filtering the air and collecting all types of harmful substances like mold spores which are hard to catch. There is also the HEPA-FreshPlus filter that is for capturing chemicals from the air and the last one is the HEPA-OdorCell that will focus mainly on removing all the bad odor from your home.

Powerful Fans

Probably the one thing that the majority of purifiers are missing is a powerful fan that will circulate the air at much higher rate. However, that is not an issue with this unit, the Alen BreatheSmart FLEX Customizable Air Purifier is one of the few filtration products that have a unique fan which can work at very high speeds with little noise.

Filter Life Indicator

A very helpful feature that is unique to this product is the filter life indicator that is built in just for one purpose. That purpose is, of course, to warn you if the filtration is no longer good for use. When you see that the filter is no longer good, you need to change it as soon as you can. This way you will not use your filter when it is actually full of harmful substances and it is unable to filter anything else.

Other Features of the Unit

There are plenty more features that the Alen BreatheSmart FLEX Customizable Air Purifier can offer. These additional features are here to make your life easier by doing some important things for you. More importantly, these features will improve the air quality inside your home even more.

  • 14 Panel options are just one of those features that we have to mention. You have the option to choose between 14 different designs of the device. All of the 14 panels are specially designed to fit different types of home decors. There are 14 design and color variations that will blow your mind, anything from simple one colored to a wooden design you will be able to choose from.
  • The power/sleep mode is another addition that will be very helpful to you. With this feature, you will be able to set a timer on when the device will turn on and off. Furthermore, you can set for how long do you need it to work and you also must decide the speed of the fan that you want.

Easy and Simple Use

The greatest thing about this product is that it is very easy and simple to use. Unlike other similar products, this air purifier is ready to be used right out of the box. There is no need for some special setup, it comes with the standard filter and only if you want to change it to let’s say Silver HEPA filter, you will need to take it apart in order to replace the filter.

What is Wrong with the Product?

When it comes to this particular air purifier, there is almost no bad side, but if we had to point one thing out that we didn’t like about it is probably the noise. However, the noise is something that comes with most of the product that has a powerful fan. That is simply something that you already knew before purchasing it. furthermore, in larger rooms that are close to 700 square feet, you cannot even hear it working.


After a complete test of the device under harsh circumstances, we can say with confidence that the Alen BreatheSmart FLEX Customizable Air Purifier with HEPA-Silver Filter is the best air filtration system for your home.
