The standard filtration packaged at the factory with each vacuum is a 3M® Filtrete electrostatic microfilter. This is the same type filter used in hospitals to keep biological contaminates in check. The filtration efficiency tests done on Lindhaus vacuums by the independent laboratory IBR (USA) show the result of a Lindhaus sealed filtration system.

All models of Lindhaus vacuums can also be fitted with an optional S-class HEPA filter for filtration of particles 0.3 microns or larger at an efficiency of 99.97%

This allows you to achieve a higher level of filtration during the allergy seasons or when contaminants may be at a higher level in your home, such as after dusting.
