As the automotive aftermarket, commercial vehicle, and construction machinery sectors continue to develop, filter sourcing is gradually shifting from single-product purchasing toward multi-category, multi-part-number, and bulk procurement.
For importers, wholesalers, and distributors, supplier evaluation is no longer based only on price or the specifications of one individual filter. Buyers increasingly consider whether a supplier can cover multiple product categories, continuously expand its part-number range, and support stable bulk supply.
Hebei Lantu Technology Co., Ltd. has long been engaged in the research, manufacturing, and sales of automotive components and has gradually developed filtration into one of its key business areas.
Today, LANTU’s main product portfolio covers air filters, oil and fuel filters, cabin air filters, and related filter assemblies.
This product structure was not created at one time. It has gradually developed through years of manufacturing experience, product development, and market accumulation.
LANTU’s development can be traced back to 1996.
According to the company’s development records, its early business mainly focused on automotive components such as sealing strips and hoses. The company also supplied related products to vehicle manufacturers including Shifeng, Feicai, Jinwa, Yuejin, JAC, and Chery.
As the business developed, LANTU gradually entered the filtration industry, registered the LANTU trademark, and placed a stronger focus on filter products.
Later, the L1, L2, and L3 product series were introduced to the market. LANTU also developed nano filter products and expanded into oil filter and fuel filter production.
This development reflects a gradual transition from traditional automotive component manufacturing toward a more specialized filtration business covering air intake, lubrication, fuel, and cabin air filtration.
Air filters are an important part of LANTU’s current product system.
According to company materials, LANTU has developed multiple air filter series for different product positioning and operating requirements.
For example, the L3 series uses deep-corrugated, high-stiffness, high-dust-holding filter paper with relatively high air permeability. PU sealing materials are also used to support sealing performance and long-term stability.
LANTU’s company materials also introduce its nano air filter series. This series uses nano-fiber filter media and was developed around water resistance, dust release performance, and extended service life.
From conventional air filter elements to different media and product series, LANTU’s air filter business has gradually developed beyond a single structure and into a broader portfolio for different markets and operating conditions.
Building on its air filter business, LANTU has also developed oil filter products.
The main function of an oil filter is to remove metal particles and other contaminants from engine oil, reducing the risk of these impurities entering the lubrication system and accelerating component wear.
The company’s materials also introduce spin-on oil filter structures. These products use the micro-porous structure of filter media to remove impurities from engine oil and help protect the lubrication system.
For some oil filter products, LANTU uses multi-layer synthetic filter media combined with supporting mesh technology to improve media stiffness and dust-holding capacity. The filter element design also emphasizes suitable pleat quantity and consistent pleat spacing to maintain effective filtration area.
With the addition of oil filters, LANTU’s product coverage has expanded from engine intake filtration into engine lubrication systems.
Fuel filters are another important category within LANTU’s expanding product portfolio.
Current company materials include common-rail fuel filter products and describe design elements involving filter media, housings, sealing components, threaded cover plates, and water-separation functions.
These products are designed to help remove particles and water from fuel, reducing the risk of contamination, corrosion, and wear within fuel injection systems.
Fuel filters are therefore not simply an additional product category. Their development requires attention to filter media, housing structure, sealing performance, and the operating environment of the fuel system.
Together with oil filters, the fuel filter range has further strengthened LANTU’s coverage of engine filtration systems.
LANTU’s filter portfolio also includes cabin air filters.
According to the company’s current materials, some LANTU cabin air filters use activated carbon materials. These products are designed to separate dust, pollen, and other airborne particles while using the adsorption properties of activated carbon to help reduce odors and certain gases.
This category expands LANTU’s filtration business beyond engine intake, lubrication, and fuel systems and into the passenger compartment.
Air filters, oil filters, fuel filters, and cabin air filters each serve a different filtration position within a vehicle, helping LANTU build a broader product portfolio across multiple systems.
As the product system continues to expand, LANTU’s air filtration business has also moved further into construction machinery applications.
LANTU’s existing construction machinery honeycomb filter materials include multiple honeycomb air filter part numbers, including P611720, 621983, PF9001000M, 422879, 2525001-2525002, P603577, P613522, and P610875.
The catalog also includes application references associated with John Deere, Lonking, Caterpillar, Ford, and GMC.
The addition of honeycomb air filters has practical significance for LANTU because it extends the company’s air filtration range beyond conventional vehicle filters into more specialized construction machinery applications.
For bulk buyers, this expansion means that more products for different machines and part numbers can be sourced within the same supplier system.
A multi-category filter portfolio is not simply about having more products in a catalog.
Air filters, oil filters, fuel filters, cabin air filters, and honeycomb air filters all serve different systems and require different filter media, dimensions, structural designs, sealing methods, and manufacturing processes.
Continuous expansion therefore depends on long-term R&D, production experience, and product development capability.
LANTU’s company development records show that the company established the Hebei Provincial Filter R&D Center and was recognized as a Specialized and Innovative Enterprise.
In 2024, LANTU obtained IATF 16949 system certification. In 2025, the production base was relocated and expanded, while production of air filters, oil filters, and fuel filters was further increased.
Company materials also state that LANTU continues to invest in R&D and explores new technologies, processes, and materials to support product development.
These capabilities provide an important foundation for the continued expansion of the company’s filter product portfolio.
As the product range has expanded, manufacturing capacity has also increased.
According to LANTU’s company materials, annual production is approximately 1 million air filters and around 3 million oil and diesel fuel filters, with total annual filter production exceeding 4 million units.
This means LANTU’s multi-category portfolio is not only based on product variety but is also supported by growing production capability.
For overseas importers, wholesalers, and distributors, this type of supply system can be particularly useful for mixed-model orders and bulk purchasing.
Instead of sourcing each filter category from a different supplier, buyers can combine air filters, oil filters, fuel filters, cabin air filters, and construction machinery air filters within one supply system, helping simplify supplier management and order consolidation.
Looking back at LANTU’s development, it is clear that the company’s filtration business has not been built around only one individual product.
From L1, L2, and L3 air filter series to nano air filters, oil filters, fuel filters, cabin air filters, and honeycomb air filters for construction machinery, LANTU is gradually building a product portfolio covering different filtration systems and application scenarios.
For LANTU, multi-category development is not simply about increasing the number of SKUs.
It is about combining ongoing R&D, production expansion, and part-number development so that customers can access a more complete sourcing solution across different vehicles, machines, and filter applications.
LANTU will continue developing air filtration, lubrication filtration, fuel filtration, and related specialized filter products to support the bulk sourcing needs of global wholesalers, importers, distributors, and filter buyers.
