Do Reverse Osmosis Systems Really Remove PFAS?

If you’re like many people, you’ve probably heard the term PFAs floating around in conversations about water purification. 

But what does it really mean, and more importantly, can a reverse osmosis system effectively remove these potentially harmful substances from your drinking water? 

At Diamondback Plumbing & Cooling in Phoenix, Arizona, we are here to shed light on this matter. Our goal is to simplify the complex world of water purification and help you make informed decisions about the quality and safety of your drinking water.

Buckle up as we dive deep into the heart of reverse osmosis systems and their efficiency in PFAS removal.

The Impact of PFAS on Drinking Water and Human Health in the United States

PFAS, short for Per- and polyfluoroalkyl substances, are a family of manufactured chemicals that have been extensively used in numerous everyday products since the mid-20th century. Due to their persistence, they have garnered the nickname “forever chemicals.”

You might be wondering, “Why should I be concerned about PFAS?”. Well, research indicates that these chemicals can infiltrate the water we drink, harming our health and households. When ingested, they can accumulate and stay in the human body for extended periods. 

Some studies have linked them to certain health conditions, including hormone disruption and weakened immune response. In some cases, they can even foster the growth of harmful bacteria in your water systems.

At Diamondback Plumbing & Cooling, we understand the gravity of this situation and are committed to problem-solving in this area. With our advanced reverse osmosis systems, we aim to provide a robust solution that effectively combats the PFAS problem, ensuring the health and safety of your family.

The Effectiveness of Reverse Osmosis in PFAS Removal

You might be wondering, “Why should I be concerned about PFAS?”. Well, research indicates that these chemicals can infiltrate the water we drink, harming our health and households. When ingested, they can accumulate and stay in the human body for extended periods. 

Several scientific studies have validated the effectiveness of RO systems in eliminating these ‘forever chemicals’ from water. High-quality RO systems such as those offered by Diamondback Plumbing & Cooling can remove up to 99% of PFAS, significantly reducing the associated health risks for everyone living in your house.

Managing Risks through Regular Maintenance and Checks

However, the effectiveness of an RO system in PFAS removal is more than just a one-and-done deal. It demands regular checks and maintenance. Over time, the membrane may become clogged or damaged, compromising its filtration efficacy. At Diamondback Plumbing & Cooling, our expert team recommends and provides regular maintenance services to ensure your RO system continues functioning optimally.

In addition, periodically testing your water for PFAS is another risk management strategy. Water source quality can vary, and even a well-functioning RO system must be monitored for performance. Regular testing verifies the effectiveness of your RO system and helps identify any new potential threats to your water quality.

Diamondback Plumbing & Cooling ensures your water is safe and clean. With our comprehensive approach to risk management, we ensure that your RO system effectively removes PFAS, safeguarding the health and well-being of your family.

Reverse Osmosis vs. Activated Carbon Filtration

When it comes to the removal of PFAS from water, it’s important to understand the capabilities of different water treatment methods. Two popular methods are reverse osmosis (RO) and activated carbon filtration.

Reverse Osmosis (RO) has proven to be highly effective at removing PFAS. As mentioned earlier, this method uses a semi-permeable membrane capable of removing up to 99% of PFAS. This ensures that your water is significantly free of these potentially harmful substances.

On the other hand, Activated Carbon Filtration operates on a different principle. It traps contaminants in the pores of an activated carbon filter. While it removes specific contaminants efficiently, its effectiveness against PFAS is variable. 

Some studies indicate that activated carbon can remove PFAS, but its efficiency depends on several factors, including the type and concentration of PFAS, the age of the filter, and the water temperature. It may not always reach the same level of consistency in PFAS removal as an RO system.

While both methods offer valuable solutions for water purification when it comes to PFAS removal, reverse osmosis systems, like those provided by Diamondback Plumbing & Cooling, tend to deliver more consistent and reliable results.

Cost Considerations and Feasibility of Reverse Osmosis for PFAS Removal

While reverse osmosis (RO) systems are undeniably effective in removing PFAS, it’s important to consider the cost implications of this water purification method. The initial outlay for a high-quality RO system can be sizable, typically ranging from a few hundred to several thousand dollars, depending on the complexity and capacity of the system.

Moreover, the ongoing costs of maintaining an RO system should not be overlooked. Regular replacements of the semi-permeable membrane and other filter components are necessary to keep the system operating effectively. This, along with the costs of regular water tests, adds to the total cost of ownership of an RO system.

However, when weighing these costs, one should also consider the potential health costs of continued exposure to PFAS. Mitigating the health risks associated with these ‘forever chemicals’ can be seen as a long-term investment in your family’s health and well-being.

Furthermore, Diamondback Plumbing & Cooling offers competitive pricing and flexible maintenance plans to mitigate some of these costs. We believe that clean, safe water should be accessible to all, and we are committed to providing affordable, reliable solutions for PFAS removal.


In summary, PFAS contamination poses significant health risks, but these risks can be effectively mitigated with the right water treatment system. Reverse osmosis, in particular, has demonstrated remarkable effectiveness in removing these ‘forever chemicals’ from water. While there is an initial and ongoing investment involved with this method, the potential health benefits make it a worthy investment. 

At Diamondback Plumbing & Cooling, we are committed to helping you secure the health and well-being of your family with our high-quality and affordable reverse osmosis systems. We understand the value of clean, safe water, and our comprehensive services—from installation to regular maintenance—ensure that your water remains free from harmful PFAS.
