The Cube is a very powerful diffuser in a compact design to make it ultra portable. There are 20 different rate settings so that the amount of mist discharged suits the needs of the user. Timing is also programmable. The case is aluminum with acrylic front that is available in either white or black (in stock). The unit is heavy and comes with a bracket for mounting on the wall or it can remain portable and moved from room to room. The bottom is padded to prevent scratching of furniture. The Cube can also be connected to the HVAC system or used to “flood” an area that needs disinfecting. Depending on the purpose of the diffusing, this model can be used for remediation in spaces up to roughly 20 x 30 feet, 150 cubic meters. It holds 16 oz. of oil. This is a very serious amount for personal use, but excellent for layering surfaces to inhibit mold growth.
