Solutions for vacuum cleaners to protect people from household contaminants

Filtration for vacuum cleaners

Freudenberg has developed a range of high-quality filters for bagless vacuum cleaners, including pre-filters, motor protection filters, high-efficiency filters (99.97% efficiency at 0.3 um or 99.95% at MPPS) for exhaust air, and carbon filters for odor removal. All filters are customized to the specifications of the vacuum cleaner manufacturers and to improve the performance of vacuum cleaners. Washable filters, functional treatment and HEPA filters in compliance with the EN1822 standard are available upon request.

Customer benefits

Our filters offer maximized collection efficiency, low air resistance, optimum air-permeability/intake performance, high dust-holding capacity, and a long lifetime. The combined electrostatic filtration effect and mechanical filtration efficiency are excellent for use in small spaces and can be customized to the necessary geometry of each individual application.

Pre-filter

The pre-filter is located in the air inlet of the vacuum cleaner to remove coarse particles and provide protection for the downstream filters. The pre-filter can be produced using nonwovens, mesh, foam or other filter medium and with rigid or soft frames.
