Cabin filter

Cabin filters stop contaminants, including dust particles, pollen, water droplets and gaseous pollutants to get into the passenger compartment. The Reisse range covers both carbon and polymer filters. Carbon filters will filter all of the same particles as a regular polymer particulate filter. However they also include a layer of activated carbon which will absorb unpleasant noxious gases and unpleasant odors from entering the Cabin.

Cabin filters should be replaced every 10,000 miles / once per year or according to the vehicle manufacturer specifications but is often missed when the vehicle is serviced. Ambient dust, plant dust, exhaust fumes, cigarette ash, pollen, bacteria, brake residue, mould, sulphur oxide and various other particles are all pollutants that can get inside the cabin of a car if the filter is not replaced. The build up of bacteria and micro-organisms will pass through the filter, affecting the health and well-being of its occupants. This is frequently known as “sick car syndrome” as it can leave occupants suffering from flu like symptoms and headaches.

Today more than 90% of new vehicles have a cabin filter, with or without air conditioning. An old filter results in the multiplication of bacteria inside the vehicle (possible concentration of between 5 to 8 times higher than normal depending on traffic conditions). Without a cabin filter the air inside the vehicle will contain 10 times more pollutants than the air outside. In an urban environment, the filter breaks down much more quickly. In traffic jams or at reduced speed, the motorist and his passengers are subject to what is known as the “tunnel effect” where exhaust fumes are sucked into the cabin creating a tunnel of exhaust fumes. To avoid all these complications, it is important to follow the manufacturer’s recommendations.

Carbon filters use a piece of activated carbon to remove contaminants and impurities, utilizing chemical adsorption. This carbon is generally activated with a positive charge and is designed to attract negatively charged water contaminants
