To choose a suitable oil filter, you need to pay attention to the following core performance indicators:

Filtration accuracy
The minimum particle size of impurities that can be intercepted by the micropores of filter paper (usually expressed in micrometers and micrometers). The higher the accuracy, the better the filtering effect, but it may have a greater impact on flow resistance.

Pollution absorption capacity
The total amount of impurities that the filter can hold before clogging. The stronger the pollutant absorption capacity, the longer the service life of the filter, and the longer the replacement cycle can be.

Flow resistance
The pressure loss when the oil passes through the filter. The smaller the resistance, the lower the load on the oil pump, and the more guaranteed the oil flow rate.

Valve setting
The existence of check valves and bypass valves and their accuracy in opening pressure.

Purchase Recommendations
Pay attention to the average filtering accuracy in the product description. High quality machine filters are usually labeled with micron level filtration accuracy.
Choose high-quality machine filters with good filter paper material and large surface area. Poor quality machine filter paper is thin, prone to clogging, and has a short lifespan.
High quality machine filters have been designed with optimized filter paper structure and flow area, ensuring filtration accuracy while minimizing flow resistance. Avoid using low-priced machine filters from unknown sources.
Be sure to choose high-quality products equipped with these two valves. The opening pressure of the bypass valve should ideally be consistent with the original factory specifications (please consult the repair shop).
