The Dual Filter™ is a combination of HEPA and activated carbon filter
	
	
	
The filter material is made in Germany
	
	
	
The HEPA part filters pollutants out of the air, such as fine dust, pollen, viruses and bacteria
	
	
	
The activated carbon filter adsorbs gases (bad smells, tobacco smoke, formaldehyde, toluene, volatile organic compounds, etc.)
	
	
	
The Dual Filter™ has to be replaced every 8–12 months
