Can I mount my air purifier on a wall?

Personal Units (AeraMax 100, 90, DX5, DB5, 200, 190, DX55, DB55, 300, 290, DX95, etc.) have not been designed to mount on walls. 

AeraMax Pro Units (AM2, AM3 & AM4) are designed to be mounted on walls. However, AeraMax Pro AM3S and AM4S are designed to be free-standing.
