Yes, certain home water filtration systems can remove or significantly reduce microplastics. Reverse osmosis filtration is currently one of the most effective technologies for removing microscopic particles from drinking water. Whole-home sediment filtration can capture larger particles, while water softeners focus on removing hardness minerals and protecting plumbing rather than filtering contaminants.

Understanding Microplastics in Water

Microplastics are extremely small plastic particles typically defined as being smaller than five millimeters. These particles can originate from a variety of sources including the breakdown of larger plastics, synthetic fibers, packaging materials, and environmental wear over time.

Researchers continue to study how these particles move through water systems, and while municipal treatment plants remove many contaminants, some microscopic particles may still be present in trace amounts.

Because of this, many homeowners are exploring in-home water filtration systems that can further improve the quality and clarity of their drinking water.

Which Home Water Systems Can Reduce Microplastics?

Not all water treatment systems serve the same purpose. Some are designed to soften water, while others filter extremely fine particles.

Understanding the differences helps homeowners choose the right solution for their needs.

Reverse Osmosis Drinking Water Systems

Reverse osmosis systems are widely recognized as one of the most effective residential filtration technologies available.

These systems use a semi-permeable membrane that filters water at an extremely fine level, often down to approximately 0.0001 microns.

Because of this level of filtration, reverse osmosis systems are capable of removing or significantly reducing many microscopic particles, including:

  • Sediment
  • Dissolved solids
  • Certain chemicals
  • Microplastics
  • Other very small particles

Tri County Water installs advanced drinking water systems manufactured by EcoWater Systems, a company known for high-efficiency residential water treatment technology.

These systems are typically installed under the kitchen sink and provide purified drinking water directly from a dedicated faucet.

Whole-Home Sediment Filtration

Whole-home filtration systems are installed where water enters the house and help remove particles before the water travels through plumbing and appliances.

Depending on the filter used, these systems can capture particles ranging from 20 microns down to 1 micron.

While larger microplastics can be captured by fine sediment filtration, extremely small particles may require more advanced filtration such as reverse osmosis for drinking water.

Whole-home filtration provides several additional benefits:

  • Protects appliances from sediment buildup
  • Improves water clarity
  • Reduces particulate matter entering the home’s plumbing system

Water Softeners and What They Actually Do

One of the most common misconceptions homeowners have is assuming a water softener filters everything.

In reality, water softeners perform a completely different function.

Water softeners manufactured by EcoWater Systems are designed to remove hardness minerals such as calcium and magnesium through a process called ion exchange.

Soft water provides several benefits including:

  • Reduced scale buildup in plumbing
  • Longer appliance lifespan
  • Improved soap performance
  • Cleaner dishes and fixtures

However, water softeners are not designed to filter microplastics or microscopic particles. For that reason, many homes benefit from a combination of water softening and filtration systems working together.

Why an In-Home Water Test Matters

Every home’s water supply is slightly different depending on local conditions, plumbing, and water sources.

The best way to determine the right water treatment solution is through a professional in-home water test.

During this test, a water specialist can measure important factors such as:

  • Water hardness
  • Iron levels
  • Mineral content
  • Water clarity
  • Overall water characteristics

This helps homeowners understand what type of water treatment system will be most beneficial for their home.

Tri County Water offers free in-home water testing so homeowners can learn more about their water without any obligation.

The Bottom Line for Homeowners

Modern water treatment systems are designed to address different water concerns, and understanding how each system works helps homeowners make informed decisions.

Reverse osmosis systems are highly effective for drinking water purification, whole-home filtration captures sediment and particles, and water softeners protect plumbing and appliances from mineral buildup.

When combined properly, these systems can dramatically improve the overall water experience in your home.

If you have questions about your water or would like to see what is in your home’s water supply, scheduling a professional water test is the best place to start.

Frequently Asked Questions


Do reverse osmosis systems remove microplastics?

Yes. Reverse osmosis filtration uses a very fine membrane capable of filtering particles much smaller than typical microplastics, making it one of the most effective home technologies for drinking water purification.

Do water softeners remove microplastics?

No. Water softeners remove hardness minerals such as calcium and magnesium. They are designed to improve water softness rather than filter microscopic particles.

What type of filter removes microplastics from drinking water?

Reverse osmosis systems and extremely fine filtration membranes are currently the most effective residential technologies for reducing microplastics in drinking water.

Can whole-home water filters remove microplastics?

Whole-home sediment filters can remove larger microplastic particles depending on the micron rating of the filter, but extremely small particles may require reverse osmosis filtration.

How can I find out what is in my home’s water?
