Alen FLEX Vs Molekule Air – Trust Comparison! (2022)

This comparison is all about the Alen BreatheSmart FLEX and Molekule Air, two air purifiers from premium brands. In this article, I will give you answers to many questions related to these two devices. 

But, firstly, let’s compare their basic specifications. The Alen FLEX is intended for rooms up to 300 sq. ft., where it will clean the air 4.8 times in one hour. On the other hand, Molekule suggests using the Molekule Air in rooms of up to 600 sq. ft., but it can clean air only once in one hour in a room of the suggested size.

Alen FLEX Vs Molekule Air - Air Purifiers Comparison

Regarding design, I must say that the Molekule Air is a premium air purifier made of an aluminum case with some plastic details. I believe this one is the best-crafted air purifier on the market. Alen FLEX has no metal parts, it’s entirely made of plastic, but it looks premium, eye catchy, and modern.

What else I could say is that I like Alen’s filtration technology more than Molekule’s. It uses a three-stage filtration technology, has a True HEPA filter, and performed amazingly in performance tests. At the same time, Molekule uses PECO filtration technology, which is their own patented technology. Overall, it showed a bit worse performance than the Alen.

Keep reading, and find out which one performed better in other tests, which is better in specifications, but which one was better in real-life tests.
