The spin-on oil filters consist of an element located in a steel threaded housing with which the filter is screwed directly to the engine body.

Cartridge oil filters 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.

White non-woven 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 fibers.

Activated carbon is a common material in various filters, active carbon cabin filter stop not only solid particles but also harmful gases. The activated carbon has a porous structure that is similar to graphite. It attracts harmful gases by means of adsorption. Activated carbon also absorbs unpleasant odors entering the passenger cabin from the outside. blocks harmful gases, such as ozone, sulfur dioxide, and nitrogen oxides.

The filter paper of our pu type air filters adopts high-efficiency filter paper imported from Germany, which still has high-efficiency filtration effect under the effect of high-efficiency ventilation.

Our pp type air filters are panel filters using synthetic non-woven fabrics. Synthetic non-woven fabrics have very good filtering performance, but the hardness is lower than that of cellulose blotting paper.

The white non-woven air filter is just a filter similar to pp type air filter, but without plastic material, this filter has an environmentally friendly filter non-woven material, which is commonly used in Japanese models. This kind of white non-woven air filter production process is simple and saves the use of raw materials. Our white non-woven air filter has environmental performance and is worthy of promotion.
