Both PFAS and microplastic in water are serious concerns, but PFAS are generally more dangerous because they are toxic, persistent, and build up in the body over time. Microplastics are widespread and can carry harmful chemicals, but PFAS are directly linked to health risks like cancer and hormone disruption. The real solution is not choosing which is worse. It is removing both with a properly designed home filtration system.

What’s the hard truth about PFAS and microplastics in your water?
You are not dealing with one problem.
You are dealing with a cocktail of contaminants working together. That is what most companies will not say out loud.
I have been in this industry since 1972. I have tested water all across Orange County. Here is what I can tell you clearly.
The danger is not just what is in your water. It is how these contaminants interact over time.
Which is worse in water PFAS or microplastics?
PFAS are generally worse. They are more toxic, more studied, and more directly linked to serious health issues.
But that does not make microplastic in water harmless. Here is the honest breakdown.

PFAS:
- Known as “forever chemicals”
- Do not break down in the environment or body
- Linked to cancer, hormone disruption, and immune issues
Microplastic:
- Tiny plastic particles found almost everywhere
- Can carry chemicals like PFAS and heavy metals
- Build up in the body over time
So the real answer is this. PFAS are the toxin.
Microplastics are often the carrier.
What exactly are PFAS and why are they so dangerous?
PFAS are man-made chemicals used in products like:
- Non-stick cookware
- Waterproof fabrics
- Food packaging
They entered water systems decades ago and have stayed there.
Why PFAS are a major concern:
- They do not break down
- They accumulate in your body
- Even very small amounts can matter over time Think of PFAS like a stain that never washes out. Once it is in your system, it tends to stay.
How is microplastic in water different from PFAS?
Microplastic are physical particles, not chemicals. But here is where it gets serious.
What microplastics do:
- Enter your body through drinking water
- Carry chemicals on their surface
- Act like tiny delivery systems for toxins
“If PFAS are the poison, microplastics can be the vehicle that carries it deeper into your body.”
That is why ignoring microplastic in water is a mistake.
Are PFAS and microplastic found in Orange County water?
Yes. Both PFAS and microplastic in water have been detected in various water sources across California, including Orange County.
In coastal areas like:
- Irvine
- Newport Beach
- Huntington Beach
You have multiple contributing factors:
- Historical industrial contamination
- Environmental runoff
- Ocean-related microplastic cycles
The water is treated and managed well. But these contaminants are part of a larger, modern challenge.
Why is comparing PFAS vs microplastics the wrong question?
Because you are not exposed to just one. You are exposed to both.
And sometimes, they interact.
The real issue:
- PFAS can attach to microplastics
- Microplastics can carry other pollutants
- Combined exposure may increase long-term risk
It is not a competition. It is a combination. And that combination is what you need to address.
What actually removes PFAS and microplastic in water?
You need a system designed to handle both.
Proven solutions:
- Reverse Osmosis systems for PFAS and microplastics
- Advanced carbon filtration for chemical removal
- Multi-stage systems for complete coverage But here is the truth most companies avoid.
Not all systems are built to remove both effectively.
That is where expertise matters.
Why do most water systems fail to solve this problem?
Because they are built to sell, not to solve. Most companies:
- Offer one system for everyone
- Focus on one contaminant
- Ignore local water differences That is not how water works.
We approach it differently.
We are the Auto Mall of water treatment.
We do not push one brand. We analyze your water and match the right system to your home. Because water in Laguna Niguel is not the same as water in Irvine or Newport Beach.
How do you know if your water has PFAS or microplastics?
You start with proper evaluation.
We offer a Free, In-Home Water Test where:
- We test your water on-site
- You see results immediately
- We explain everything clearly
- There is zero pressure
We do not send samples away and leave you waiting. You get answers right there in your home.
What guarantee do you have that the solution will work?
We stand behind our work fully.
“If the system we install doesn’t perform the way we promised… If your water doesn’t taste, feel, or behave the way we said it would… We’ll pull the whole system out. And either replace it or make it right. No fine print. Because your trust is worth more than the sale.”
That is how we have done business for over 50 years.
What should you do next if you are concerned about PFAS or microplastic in water?
Do not try to choose which is worse. Fix both.

Which is worse in water PFAS or microplastics?
PFAS are generally considered worse because they are toxic, persistent, and linked to serious health risks, while microplastics act more as carriers of contaminants
How is microplastic in water different from PFAS?
Microplastics are tiny plastic particles that can carry harmful chemicals, while PFAS are man-made toxic chemicals that accumulate in the body and do not break down.
What actually removes PFAS and microplastic in water?
Properly designed home filtration systems such as reverse osmosis and multi-stage filtration can effectively remove both PFAS and microplastics.
Posted on Henry NovellTrustindex verifies that the original source of the review is Google. Maaison does excellent work. I highly recommend. He is very experiences and could answer all my questions related to The Hague water softener and the RO water filtration system. Highly recommend Brian and his team of employees. He has low turnover which speaks volumes for a good operation.Posted on Ethan BlairTrustindex verifies that the original source of the review is Google. No matter what you have installed or serviced, this company knows what they are doing. I’ve never know a company to have such intelligent and capable employees all around. From quotes, to scheduling, service and follow up you are in the most capable hands. We have been with McCowin water for 7 years and only encountered positive results. Employees are happy and love the company! It’s the coolest thing to witness. Thank you for being such a steady and loyal partner in keeping our water and home protected. You are family to us!Posted on Tom PhillipsTrustindex verifies that the original source of the review is Google. Very friendly and professional technician. Great customer skills as well. He couldn't say enough nice things about the company. Answered all questions I had.Posted on Mike MichinoTrustindex verifies that the original source of the review is Google. This is the most well run, professional, punctual, competent, and honest business I have ever encountered across any field. It definitely shows that it is a family run business that takes personal pride in its work, its employees, and its integrity. Every single service tech who has come out to our home has been the quintessential professional. All experts at what they do, meticulous, and complete in every detail. They do not cut any corners. I love tinkering with mechanical things and am very OCD when it comes to my water quality. I was especially pleased to discover them using the same and better “Hach” water testing equipment that I personally use, and making sure to perform all of the tests as part of their standard routine, with no prompting from me. What particularly left an impression on me was the visit from technician Maaison today. After thoroughly completing all of the annual checks, he courteously asked me multiple times if I had any questions. I could not think of any because he was already so thorough in all of his explanations and demonstrations. But then when he went to update the interface on my unit, he noticed me quip that I would have to consult the manual to learn how to do that myself. Maaison not only re-explained the procedure again, he actually jumbled the controls and allowed me to reprogram the interface myself to make sure that I could actually do it myself after he left. As I attempted to implement his teachings, Maaison continued to attentively pay attention and pointed out the mistakes that I made and corrected them in the kindest most respectful way possible. The employees of this company are not only great people, they are great teachers, and we all know what kind of person it takes to actually teach (I mean the good teachers, lol) and pass on knowledge. Kudos to McCowin Water, Inc! What an amazing company.Posted on Juliet WilliamsTrustindex verifies that the original source of the review is Google. Maaison was great and super helpful!
