5 Micron vs 20 Micron Sediment Filters: What’s the Difference?

When shopping for sediment water filters, one of the most common questions is whether to choose a 5 micron or 20 micron filter. Both can be useful, but they are designed for different filtration needs. Understanding the difference can help you select a filter that fits your home, water source, and water pressure requirements.

What Does Micron Mean?

A micron is a unit used to describe particle size. In water filtration, the micron rating tells you the approximate size of particles a filter is designed to capture. A lower number means the filter is designed to capture smaller particles. A higher number means it allows larger particles to pass compared with a lower-rated filter.

For example, a 5 micron sediment filter is generally used for finer particles, while a 20 micron filter is often used for larger sediment such as sand, dirt, or rust flakes.

When to Choose a 5 Micron Filter

A 5 micron filter may be a good choice when your water contains fine sediment or when you want a more detailed level of particle reduction before water moves to another filter stage. It is commonly used in whole house systems, under sink systems, and pre-filtration setups.

However, because it captures smaller particles, it may clog faster if the water contains a large amount of sediment. This can reduce water flow and require more frequent replacement.

When to Choose a 20 Micron Filter

A 20 micron filter is often used when the main issue is larger visible particles. It may allow stronger water flow compared with a finer filter and can be useful as a first-stage filter in homes with heavy sediment.

For well water, a 20 micron filter may help catch larger debris before water reaches a finer filter. This staged approach can help reduce clogging in later filters.

Can You Use Both?

In some systems, using both may make sense. A 20 micron filter can be placed before a 5 micron filter to catch larger particles first. Then the finer filter can focus on smaller sediment. This is common in multi-stage filtration setups.

Buying Tips

Before choosing, check your current filter size, housing type, water source, and flow requirements. If your water pressure drops quickly after installing a fine filter, you may need a larger micron rating or a staged setup.

Conclusion

A 5 micron filter is usually better for finer sediment, while a 20 micron filter is often better for larger particles and stronger flow. The best choice depends on your water condition and filtration system design.
