SilentMaster's unique filtration design makes for a healthier home and simple maintenance. SilentMaster brings debris in from the top where it compacts into a large paper bag with over 11 feet of surface area. The tapered shape of the bag allows air to flow around the debris. By contrast, most competitive central vacuums have a design flaw that involves bringing debris into the bottom where it is constantly swirling around and impeding the small filter which has only one foot of surface area.

Because of SilentMaster's huge trash capacity it is months before a filtration change is needed. Compared to other systems, changing the filter is easy. There is no bucket to dump or filter to shake; instead, just set the dirty paper bag in the trash. Plus, having the motors at the bottom with two exhaust ports allows them to stay cooler and last longer than ones in top mounted cyclonic units

Pioneering silent technology, MD designed and produced the first quiet central vacuum via patented technology and sound absorbant material (left) strategically placed in the unit. SilentMaster's internal noise suppression system silences the unit down to 62dB (below normal conversation level). That's the power of SilentMaster
