The materials of car air conditioning filters can be roughly divided into six types. Let me introduce them to you

How to correctly understand the material of car air conditioning filters and choose the right air conditioning filter for yourself

1. Classic white filament material n2. Double-sided filament carbon fiber material
2. High air volume electrostatic network material n4. Pure imported activated carbon material
3. Common activated carbon material n6. Reinforced yellow filament material

All materials have their own advantages and disadvantages. Now let me explain to you that the materials of automotive air conditioning filters in the current market can be roughly divided into six types:

1. Classic white filament material

White filament, as the most classic material for air conditioning filters, has been renowned for its large air volume since its research and development

The advantage of fuel efficiency has been used up to now, but its disadvantage of poor filtration performance is equally prominent

It is obvious that long-term use will cause certain pollution to the air conditioning fan and pipes

Damage is gradually fading out of the market nowadays.

Advantages: Large air volume. Fuel-efficient. It is not easy to breed bacteria and does not produce unpleasant odors after long-term use.

Disadvantage: Single-effect filtration. It cannot filter out fine dust particles. Long-term use will cause damage to the interior of the vehicle

And dust accumulates in the air conditioning pipes. It is not recommended to use it in areas with strong wind and sand and a lot of dust.

Second, double-sided long-fiber carbon fiber material

As a long-established flagship material, it undoubtedly offers the best value for money.

Advantages: Light material. Large air volume. Affordable price. Can filter the tiniest dust particles.

Disadvantage: Single-effect filtration. Because it is a three-layer sandwich design, it can be used for a long time in a humid environment

It is prone to bacterial growth and is recommended for use in areas with a lot of sand and dust and a dry climate.

Three, high air volume electrostatic grid material

As a newly popular material in recent years, grid material has fully integrated high-tech means - photocatalyst

The technology at its core can generate electrostatic energy by itself to adsorb bacteria and dust, and release a large amount through photocatalyst technology

High ions make the air quality inside the car fresher. Nowadays, they are mostly used in mid-to-high-end models of Japanese and Korean brands.

Its advantages are very clear. It continues the tradition of high air volume and significantly improves the air quality inside the vehicle.

The drawbacks are also quite obvious. Photocatalysts naturally rely on light and will lose their effect in the absence of long-term lighting

Partial function.

Advantages: Large air volume, fuel saving, effectively improving the air quality inside the vehicle

Disadvantages: Some of its functions are lost in the absence of light for a long time, and other aspects remain unclear.

Fourth, made of pure imported activated carbon

Pure imported activated carbon, as the most advanced material in the current market, its filtering performance is beyond doubt.

It adopts pure natural coconut shell carbon particles as the interlayer, with highly breathable long-fiber filter cloth on both sides, which is naturally bonded by hot melt technology.

No chemical adhesives are added. Everyone knows the function of activated carbon, which can adsorb and filter air

It contains most of the toxic gases such as methanol and carbon monoxide, and is the only one in the market that can be double-filtered

The material is mostly used in high-end European and American car series such as Mercedes-Benz and BMW. Nowadays, it is also used in some high-end domestic car series

It has gradually been adopted, but the price paid for high filtration is a relatively smaller air volume. However, over the past few years

The practice is still accepted by the majority of customers and car manufacturers.

Advantages: Dual-effect filtration, moisture-proof, and odor removal

Disadvantages: The air volume is relatively small and the price is expensive

Five, ordinary activated carbon material

There's really nothing much to say about this material. Even counterfeit versions of imported activated carbon have some dual-effect filters

The effect is rather insignificant, but the advantages are quite clear: the air volume is slightly larger and the price is relatively cheaper.

Advantage: Slightly dual-effect filtration. It has a large air volume and a relatively low price

Disadvantages: The carbon layer is very thin and contains a lot of debris, making it slightly less cost-effective

Six, reinforced yellow filament material

This material is an enhanced and advanced version of white filament, continuing the high air volume style of white filament and

It effectively improves the drawback of poor filtration and is regarded as the best for some car owners who pursue high air volume

If we talk about the disadvantages of the choice, it should be that the price is slightly high. Other aspects are still unclear.

Advantages: Large air volume, fuel saving, and long service life

Disadvantages: Relatively high price, single-effect filtration, other aspects are not yet clear

The function of the air filter:

The automotive air filter provides a clean source of air for the engine, effectively filtering out suspended particles in the air such as sand, dust, gum, aluminum oxide, iron oxide particles, etc., to reduce the early wear of cylinders, pistons, piston rings, valves and valve seats.

The function of the air conditioning filter:

It is used for filtering the air inside the car cabin and the air circulation between the inside and outside of the cabin. Generally, the filter paper of high-quality air conditioning filters is made of polymer fibers with a sandwich structure, which can effectively filter out tiny particles, pollen, bacteria, dust, industrial waste gas and various odors, and efficiently filter and adsorb particle impurities to achieve air purification performance. Or, activated carbon composite filter cloth made by combining high-efficiency adsorption materials - activated carbon with long-fiber non-woven fabric: compact in structure, it can effectively remove toxic gases such as ozone, TVOC, benzene, phenol, ammonia, formaldehyde, xylene, benzene, nitrogen oxide, sulfur and hydrocarbons. Meanwhile, the air conditioning filter also has the function of preventing the windshield from fogging up easily.

The function of the oil filter:

The oil filter is located in the engine lubrication system. It plays a very important role. It can filter out impurities such as metal shavings, carbon particles and the gum gradually formed in the engine oil that are produced and mixed into the engine oil during the combustion process, and supply clean engine oil to the crankshaft, connecting rod, camshaft, turbocharger, piston rings, etc., ensuring the normal operation of the internal combustion engine. It also serves to lubricate, cool and clean. This will greatly extend the service life of these components.

The function of the gasoline filter:

Gasoline filters are used to filter out foreign particles, impurities and moisture in the fuel required for engine combustion, to prevent accelerated cylinder wear, fuel line blockage, damage to fuel injectors and other phenomena, and ensure the normal operation of the fuel supply system.

The characteristics of automotive filters

The car filter has a high filtration performance (cleaning effect). Long lifespan (large capture capacity) It has high durability and vibration resistance, and will not cause dust leakage. It is water-resistant, will not block the entry of air, and is simple and easy to load and unload.

The application of automotive filters

A. Car filters are specifically designed to protect passengers and drivers. Air conditioning filters can filter out pollen, dust, harmful substances such as asbestos, soot, bacteria and toxic gases such as ozone, benzene and toluene in the outside air.

B. Keep related components clean: The air conditioning filter can keep the components below clean, such as fans, heaters and instrument panels, etc.

C. Activated carbon car filter: It differs from a common air conditioning filter in that it has an additional activated carbon filter layer, which further absorbs toxic gases such as ozone, nitrogen oxides, sulfur and hydrocarbons. The recommended replacement cycle for car filters is within 10,000 kilometers.

Automobile filters are mainly divided into four categories:

1. Oil filter, which filters out mechanical impurities and gum during engine operation, keeps the lubricating oil clean.
2. Fuel filters remove harmful particles and moisture from the engine's fuel and gas system to protect the fuel pump, nozzles, cylinder liners, piston rings, etc., reduce wear and avoid clogging. They are mainly divided into gasoline filters and diesel filters.
3. Air filter, a device for removing particulate impurities from the air;
4. The air conditioning filter filters the air entering the cabin from the outside, thereby enhancing the cleanliness of the air.
