Printer filters

Riensch & Held Clean Office Pro

Dangers from particulate matter do not only lurk on the road –copiers and laser printers in offices also emit fine dusts and nano particles. This is even more stressful for the employees as they often sit directly besides the equipment, which is poorly ventilated, and the fine dust penetrates deep into the lungs. In this way, even cancer can develop.

Our CLEAN OFFICE fine dust filters protect effectively against fine dust pollution when operating laser printers and copiers by reliably removing respirable fine dust from the exhaust air of the printer.


A grain of dust visible to the human eye has a size of 500 micrometers – 0.5 mm. A fine dust particle no longer visible to us is smaller than 10 micrometers = 0.01 mm. And the finer these particles are, the easier and deeper they can be absorbed via the respiratory tract into the bloodstream and thus into the organs. It is also called overcoming the blood-air barrier. This makes the new printer filter CLEAN OFFICE PRO even more important, as it is more powerful than all printer filters previously sold.
