ABSTRACT:
A replaceable vacuum cleaner hose cover made from a tube of circularly knitted yarn and a replaceable vacuum cleaner bag each having a ground yarn surface and terry loops extending from the ground yarn surface. The yarn used in forming the cover and bag is conventional multifilament crimped polyester or nylon yarn interspersed selectively with a carbon strand or strand segments, the strand effective for conducting electrostatic charges from the vacuum cleaner and vacuum cleaner hose to prevent electrostatic discharges that could occur from high electrostatic charge build up or inadvertent gas leakage within an environment and for eliminating algae and dust mites as a result of the electromagnetic field resulting from the use of this material.
