Filtron filters

The FILTRON filters owe their quality and reliability to the modern and advanced technologies used in our production plants. More than 2,000 specialists are responsible for the production of FILTRON-brand filters. Our range holds more than 2700 products, and covers 97% of the European passenger-car market.


The air filter stops impurities from the air sucked in by the engine and helps maintain the appropriate engine power, torque, and low fuel consumption. If not for the filter, polluted air – full of pollen and street dust – would go straight into the combustion chamber. Engine impurities act like abrasive paper and cause damage to piston rings, bushes, and cylinders.

Round filters

These are becoming less and less popular because the space used for air intake systems in modern passenger cars has been significantly reduced due to the installation of many additional systems (e.g. air conditioning). Circular filters with a complex structure, are popular in high-capacity premium vehicles.

Panel filters with cellulose blotting paper

Panel air filters with cellulose blotting paper are installed in most of today’s models of passenger cars and light commercial vehicles. The technology of producing these filters is complicated due to the need to use, in many cases, elements increasing the rigidity of the filter pleats.

Panel filters with synthetic non-woven fabric

Synthetic non-wovens have very good filtration properties, but are less rigid than cellulose blotting paper. To ensure the proper stiffness of synthetic non-woven filters, the filter medium is placed in a plastic frame created by injection moulding. Additional reinforcement can be provided by a special plastic mesh, which also protects against damage during operation.


The oil filter stops impurities in the oil which are passed on from the combustion chamber and are created during the friction of the engine parts that are working together. If not for the filter, the contaminated oil would increase the wear of the moving parts, which would directly increase the risk of engine damage.

Spin-on filter

This type of filter consists of an element located in a steel threaded housing with which the filter is screwed directly to the engine body. The advantages of the spin-on filter are the high resistance of its structure to damage and the simple process of its replacement. Replacing the spin-on oil filter happens virtually without the risk of introducing impurities into the engine oil system.

Oil filter element

They are mounted in sealed housings integrated with the engine. Housings usually have all the valves needed for proper filter operation in the engine oil system and the parts positioning the filter element, which guarantee its tightness in the housing. Modern oil filter elements are manufactured without the use of metal parts. The bottom-caps and cores of this type of filters are made of modern plastics. The lack of metal components is not only better for the environment but makes for easier disposal.


The fuel filter stops contaminants found in fuel which can include rust, metal chips, dust, and other solid particles. The effects of inadequate fuel filtration can be: a significant decrease in engine power, the disturbance or interruption of the fuel supply, damage to fuel-system components.

Filters with connectors

These filters have the form of a sealed metal or plastic housing with connectors to the appropriate fuel lines. They are used in both petrol engines and diesel engines. Selected filter models with connectors for diesel engines have multi-stage filtration systems. These systems increase filtration efficiency and extend the lifespan of the filter.

Fuel filter elements

These are used mainly in diesel engines as a removable element mounted in a housing integrated with the engine. Modern fuel filter elements are manufactured without the use of metal parts. The bottom-caps and cores of such filters are made of appropriately selected fuel-resistant plastics. The lack of metal components makes it easier to dispose of the filter.

Screw-in filters

These resemble spin-on filters, however they do not contain any internal valves. This is due to the fact that only pure fuel should enter the combustion chamber of the engine. It is better for the engine to stop working because of a lack of fuel flow (obstructed filter) than for it to be powered by contaminated fuel. In the case of screw-in fuel filters, the likelihood of accidental introduction of impurities to the fuel system during the replacement of filters is minimal.


The cabin filter purifies the air which passengers and the driver breathe in the cabin of the car. This filter is extremely important, because polluted air significantly affects our health and our concentration while driving. Polluted air is a very serious threat. According to official data from the European Environment Agency: due to polluted air, over 460,000 people die prematurely in Europe alone, the problem of over-polluted air concerns 80% of the residents of all urban areas in Europe.

Standard filters

Cabin filters have a filter barrier made of fully synthetic non-woven fabric. The ability to filter particles as small as a few microns is achieved through attracting pollutants by electrostatically charged fibres. Synthetic fibres are not hygroscopic, which means water does not cause cabin filters to deform.

Activated carbon filters

Activated carbon filters stop not only solid particles, but also harmful gases. Activated carbon has a porous structure which is similar to graphite. It attracts harmful gases by means of adsorption. Activated carbon also absorbs unpleasant odours entering the passenger cabin from the outside.
