The unpacking process was simple and quick to assemble. I observed an improvement in indoor air quality within a few days. We have two large dogs that tend to shed, and I am monitoring to assess whether there is a reduction in pet dander and dust. Overall, I am pleased with this purchase. I plan to continue using the product for a full two weeks to evaluate the filters' effectiveness.
The build quality seems very good, and the unit is quiet during operation. According to my air quality meter [Airgradient] It does very well at removing nearly everything from the air. CO2 is another matter though. I don't expect CO2 to be removed by any air purifier, so this has no bearing on the X5's performance.
