7th Generation Accord BYD F6 Air Filter Element - yellow cloth with wire air box filter

Air filter is used to filter the air in the engine to avoid harmful substance from being sucked in, including dust, soot, smog, pollen and other pollutants. If these substances enter the engine, it will increase the abrasion between the piston and the cylinder and lead to fuel to be mixed into the combustion chamber, thus increasing the engine fuel consumption and exhaust emissions, decreasing the engine power and shortening its service life.

When driving a certain mileage, a large amount of dust and impurities will accumulate the surface of the air filter, resulting in a decline in air permeability, therefore, the air filter must be replaced regularly.

BENEFITS

1. Clean the air that goes into the engine, holding the dust and abrasive particles in the filter, thereby avoid engine wear and tear
2. High dust separation efficiency.
3. Help maintain regular fuel consumption.
4. Reduce engine noise and optimize performance.

AIR FILTER STRUCTURE

★ Structure of Filter Paper Air Filters for Light Vehicles

1. Filter media: plant fiber pleated filter paper
2. Frame: polyurethane sealant molding frame is used to ensure the best fit and sealing.
3. Optional support mesh type
(1) Expanded metal mesh
(2) Perforated metal mesh
(3) Perforated plastic mesh
4. Optional pre-filtration layer type: In high dusty areas, air filters are provided with a pre-filtration layer.
(1) Sponge
(2) Non-woven fabric

★ Structure of Non-Woven Fabric Air Filters for Light Vehicles

1. Filter media: non-woven fabric Filter media is suitable for high humidity filtration environments.
2. Solid propylene structure.
3. Sealing polyurethane gasket: good sealing effect.

★ Structure of Single Element Air Filters for Heavy Duty Vehicles

1. End caps: it consists of a top cap and a bottom cap to combine the filter element together.
(1) Metal end caps: provided with a gasket
(2) PP plastic end cap
(3) Polyurethane (PU) end cover: high strength polyurethane structure, with better adhesion and sealing.
2. Inner support tube: It plays a role of supporting the Filter media and improving the stability of the Filter media. There are main three types:
(1) Perforated tubes
(2) Expanded metal mesh
(3) Plastic tube (generally used with PP end caps and PU end caps)
3. Filter media: high filtration efficient, pleated filter paper;regular folding space creates a higher dirt holding capacity.
4. Optional additional reinforcement layer: Provide additional reinforcement to the pleated filter paper. There are three main types:
(1) Beading stabilises the media and prevents pleat wear.
(2) Plastisol spiral winding fixation
(3) Filament spiral winding
5. Optional outer support tube: perforated metal mesh or expanded metal mesh is employed to reinforce and protect the filter media, making its structure more stable forming.

The air box filter is an essential component that plays a crucial role in maintaining the quality of air in various applications. This remarkable device is designed to filter out impurities, dust, and other contaminants from the air that passes through it.

With its precision-engineered design, the air box filter offers efficient and reliable filtration. It traps even the smallest particles, preventing them from entering the system and potentially causing damage or reducing performance. This helps to ensure a consistent and clean air supply.

The filter is made from high-quality materials that are durable and long-lasting. It can withstand the rigors of continuous use and harsh environments, providing consistent filtration performance over time.
