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.
