Easy to use, exactly what I wanted.

I have several 3D printers and was looking for an air purifier that filters TVOCs and VOCs in addition to the "normal" ones. 3D printing can release unpleasant odors, especially with technical filaments, as well as other harmful fumes.
It's especially nice that you can control the purifier with your phone.
The automatic mode also works as expected.

Unfortunately, I'm disappointed with the air purifier. I bought it to eliminate unpleasant odors in my house, but I hardly notice any difference when it's running. I don't have allergies, so I have no idea if it has any positive effects on them.
