Tips to Identify the Filters’ Quality
The quality of filters directly impacts the lifespan of the engine and the driving experience. While there are countless filter manufacturers online, it’s often impossible to determine the quality of a filter during the purchasing process. Here’s how to distinguish good filters from bad ones:
1. Air Filters
The quality of an air filter depends on materials and workmanship:
- Filter Paper: Drop iodine solution on the filter paper. If the paper turns black or deep blue, it contains starch, making it prone to absorbing moisture and deforming in humid conditions. Such filters not only fail to protect the engine but can also accelerate engine wear. We manufacture high quality alternatives for you to choose, such as AA90141 for fleetguard, 290-1935 for CAT and 01180869 for DEUTZ.

- Workmanship: Inspect for precision, glue overflow, and uneven glue edges. Poor workmanship suggests the product is not from a reputable manufacturer. For used filters, check the deformation level and whether the glue has melted. Melted glue indicates substandard material, rendering the filter ineffective.
2. Oil Filters
Many believe heavier oil filters are better, but weight doesn’t equate to quality. Instead:
- Appearance: Look for clear printing, smooth threads without jagged edges, and a well-finished iron casing.
- Material: The weight reflects the sum of its materials, not its quality. For oil filters, meeting OE (Original Equipment) standards is the ultimate goal of manufacturers.
Additional Quality Control Indicators:
- Filtration Material: As the core component, its quality determines the filter’s performance level.
- Thread Quality: Ensure the connection thread is intact and passes standard inspections.
- Seam Integrity: Inspect the smoothness and completeness of shell-to-cap crimping.
- Surface Coating: Assess the quality of powder coating or cathodic electrophoretic paint.
- Printing Clarity: Check the clarity of instructions and the adhesion of ink to the metal surface.
By evaluating these aspects, you can make a more informed decision when selecting filters. We are professional manufacturer and supplier of different filters, if you feel in need of want to get quotation, please feel free to contact us.
