The micron rating of a fuel filter is a generalised way of indicating the ability of the filter to trap particulates by the size of the particulate it is exposed to. The lower the micron rating, the finer the filtration. However, the smaller the micron rating, the faster the filter fills up. For example, a 10-micron fuel filter can theoretically capture particulates that are 10 microns or larger in size, which is about the consistency of talcum powder. A 2-micron filter will filter more contaminants than a 30-micron filter, but it is more prone to clogging. This is why it is recommended to use progressively finer filters as the fuel approaches the engine. So, which is better, a 14-micron or a 20-micron fuel filter?

What You'll Learn
The lower the micron rating, the finer the filtration
Micron ratings on filters typically range between 2 and 100, with some sources citing even smaller sizes, such as 1 micron or even 0.5 microns. The micron rating of a fluid filter indicates its ability to trap particles of a certain size. For example, a 10-micron filter can capture particles that are 10 microns or larger, which is about the consistency of talcum powder.
However, it is important to note that using a filter with an extremely low micron rating, such as 2 microns, can lead to issues. For example, water molecules are larger than 2 microns and will not pass through, which can cause a shutdown if water enters the fuel system. Additionally, filters with very low micron ratings can clog more easily, as they are more susceptible to becoming blocked by particles.
When choosing a fuel filter, it is recommended to use progressively finer filters as the fuel approaches the engine. For example, a setup with a 30-micron pre-filter, a 10-micron secondary filter, and a 2-micron final filter on the engine is commonly used. This allows for effective filtration while reducing the risk of clogging and other issues associated with extremely low micron ratings.
In summary, while a lower micron rating provides finer filtration, it is important to consider the specific application and choose a filter size that balances effective filtration with other factors such as flow rate and clogging potential.

10-micron filters are considered universal
The micron rating of a fluid filter indicates its ability to trap particulates by the size of the particulates it is exposed to. A 10-micron filter can capture particles as small as 10 microns in size, which is about the consistency of talcum powder. While 10-micron filters are considered universal, they are not suitable for all applications. For example, they cannot remove bacteria or viruses from liquids.
Micron ratings on filters typically range between 2 and 100. The lower the micron rating, the smaller the particle it will filter out reliably. However, very low micron filters can clog up more easily. For this reason, 100-micron filters are often used as pre-filters to protect fuel pumps and keep larger debris from clogging the post-pump filter.
In the context of fuel filters, a 10-micron filter can be used as a primary filter for a boat, with a secondary filter of 2 microns. In a three-filter system, a 10-micron filter can be used as the second filter, after a 30- or 20-micron filter, and before a 2-micron filter.
In water filtration, 10-micron filters are also commonly used. They can remove some unseen materials from water but are not effective at removing bacteria or viruses. Smaller micron filters, such as 1-micron filters, are more effective at removing bacteria and parasites such as E. coli, Shigella, and Salmonella. However, they are more prone to clogging and are more expensive.
In summary, while 10-micron filters are considered universal in the sense that they are used in a wide range of applications, from fuel to water filtration, they are not a one-size-fits-all solution. The appropriate micron rating depends on the specific application, the size of the particles to be filtered, and the risk of clogging.

2-micron filters can be prone to clogging
The micron rating of a fluid filter indicates its ability to trap particulates based on their size. A lower micron rating means that the filter will trap smaller particles. While a 2-micron filter can provide the greatest filtering and cleanest fuel, it is more prone to clogging.
Water molecules, for instance, are larger than 2 microns and will not pass through a 2-micron filter. This is beneficial because water can damage the injection pump and injectors. However, it can also cause the engine to shut down. Water in the fuel can also clog a 2-micron filter more easily.
A 2-micron filter can also be a clog waiting to happen at the most inopportune time. It is recommended to use a 2-micron filter as a secondary filter, with a larger primary filter. This is because the primary filter is intended to collect water and larger debris, which can then clog a 2-micron filter.
To prevent clogging, it is suggested to use progressively finer filters as the fuel approaches the engine. For example, using a 10 or 20-micron filter first, followed by a 2-micron filter at the engine. This setup can help to prevent clogging and ensure that the engine receives clean fuel.
Additionally, it is important to note that the choice of filter size depends on the specific application and fuel system. While a 2-micron filter may be prone to clogging, it can still be effective in certain setups, especially when used in combination with larger filters.

20-micron filters are considered damaging
A micron rating is a generalised way of indicating a filter's ability to trap particles by the size of the particles it is exposed to. For example, a 10-micron filter can theoretically capture particles that are 10 microns or larger in size.
The lower the micron rating, the smaller the particle it will filter out. While a 2-micron filter can provide the greatest filtering and cleanest fuel, it can also lead to issues as particles smaller than 2 microns, such as water, will not pass through. This can cause a shutdown when the 2-micron filter doesn't pass the water. Therefore, 20-micron filters are considered damaging when used as the only filter in a fuel system.
Using a low-quality filter with a high micron rating can lead to poor filtration performance and potential health risks due to exposure to harmful contaminants. In the case of a 20-micron filter, it can remove particles larger than the size of a white blood cell, which is considered quite large. However, it will not be able to remove smaller particles that can be harmful to an engine, such as dirt, rust, sand, and other small particles.
To prevent this, it is recommended to use progressively finer filters as the fuel approaches the engine. For example, a 20-micron filter can be used as a pre-filter, followed by a 10-micron filter, and finally a 2-micron filter at the engine. This setup ensures that larger particles are captured first, preventing clogging of the smaller micron filters, while still providing adequate protection against harmful contaminants.
It is important to note that the specific micron ratings and the number of filters used can vary depending on the type of fuel system and other factors such as the region and water supply.

Multiple filters are recommended for optimal performance
Micron ratings on filters typically range between 2 and 100. The micron rating of a fluid filter indicates the filter's ability to trap particulates by the size of the particulate it can capture. For example, a 10-micron fuel filter can theoretically capture particulates that are 10 microns or larger in size.
Using multiple filters with varying micron ratings is recommended for optimal performance. This is because a lower micron rating indicates that the filter can trap smaller particles, but it also means that the filter can clog up more easily. By using multiple filters, you can benefit from the advantages of different micron ratings while mitigating the disadvantages.
For example, in a diesel engine, it is recommended to use a 10 or 20-micron filter as the primary filter, followed by a 2-micron filter closer to the engine. This setup ensures that larger particulates are captured by the primary filter, preventing them from reaching and potentially clogging the secondary filter.
Additionally, having multiple filters in series provides redundancy, so if one filter becomes defective or clogged, the other filter can still function to trap particulates and prevent damage to the engine and fuel system. This is especially important in larger diesel engines, where the fuel system can be costly.
When using multiple filters, it is important to consider whether to plumb them in series or parallel. Running the filters in series means that the fuel passes through each filter sequentially, providing better filtration but also increasing the pressure drop. On the other hand, running the filters in parallel increases the capacity of the system to handle debris but does not increase the efficiency of filtration.

Frequently asked questions
Micron ratings on filters refer to the size of the particles they are able to trap. A lower micron rating means that the filter can trap smaller particles.
A nominal micron rating indicates the percentage of particles of a certain size that a filter can trap. For example, a 10-micron filter with a 50% nominal rating will trap half of all particulates that are 10 microns or larger. An absolute micron rating indicates the percentage of particles of a certain size that will be trapped by the filter media.
The ideal micron rating for a fuel filter depends on the specific application. For carburetor engines, a 10-micron filter is usually sufficient. For injected engines, a 2-micron filter is recommended to prevent damage to the fuel injectors. However, 2-micron filters can clog more easily, so it is often recommended to use a combination of filters, such as a 10-micron or 20-micron filter followed by a 2-micron filter closer to the engine.
A 14-micron or 20-micron fuel filter will allow for better fuel flow compared to a 2-micron filter, as they are less likely to get clogged by small particles. However, they may not provide sufficient filtration for certain applications, such as diesel engines, where particles between 5 and 10 microns can cause damage to fuel injectors.
