At first glance, it is clear that the Hathaspace HSP001 and Alen FLEX are completely different air purifiers. The most significant difference between these two models is in the advanced options they have. Hathaspace has a lot of advanced options, such as air quality sensors, auto mode, and similar, while Alen has only the necessary options such as timer and display off.
When comparing their room coverage, I must say that the difference is not huge because the Hathaspace HSP001 covers rooms up to 350 sq. ft., while Alen FLEX covers rooms up to 300 sq. ft.
Among other features, I would single out the 5-stage filtration technology on the Hathaspace HSP001, as well as the incredible quality carbon filters on the Alen FLEX.
One common feature of these two models is that they are very quiet. In fact, the Hathaspace HSP001 and Alen FLEX are among the quietest air purifiers I’ve tested so far, and that’s exactly why these are the devices I very often suggest for bedroom use.
In the continuation of the article, you will find a detailed comparison of these two air purifiers. I will compare their performance, operating costs, noise levels, and other specifications and determine the winner.

Which One Does It Better?
After comparing the tests’ results, my final conclusion is that the Alen FLEX is a better choice to buy than the Hathaspace HSP001.
What sets Alen FLEX apart is its outstanding performance, high-quality filters, long-lasting filters, and the possibility of activating the lifetime warranty.
The Hathaspace HSP001 is also a very good air purifier, but I don’t think it’s good enough to beat a device like the Alen FLEX is.
