Bosch Cabin Filter FAQs

This time of year with temperatures typically rising, the number of enquiries for Cabin filters tend to follow. With this in mind, Bosch have taken some time out to answer some frequently asked questions on Cabin Filters.

1. What does high cabin filter efficiency mean?

A high particle separation rate combined with a decrease in pressure being as low as possible – over the complete Cabin filter service life. The decrease in pressure is the difference in air pressure before and after the filtration.

2. What does an efficiency of 99% mean?

The filter efficiency is measured with particles of different sizes. The bigger the particles, the higher the separation rate. The new FILTER +, for instance, separates more than 99% of all particles featuring the most respirable size of 2.5 micrometres.

3. Why is it, quality and quantity of the activated carbon used for the filter are so important?

High quality activated carbon stands out for its large inner surface created at a sophisticated process in absence of air and at high temperatures. The sponge like structure neutralises harmful and foul-smelling gases. To collect as many gases as possible over the complete filter service life, both the quality and quantity of activated carbon matters.

Currently, FPS has 500+ Bosch Cabin filters in range.
