PFAS Filtration Frequently Asked Questions
What are PFAS?
PFAS (perfluoroalkyl and polyfluoroalkyl substances) are man-made chemicals used in products like waterproof fabrics, waxes, cleaning products, and non-stick surfaces. They’re often called “forever chemicals” because they take thousands of years to break down.
Are PFAS harmful to your health?
While research is still ongoing, PFAS have been linked to many potential health issues. According to the U.S. Environmental Protection Agency, PFAS is estimated to be a contributing factor in 6,800 new cancer cases each year – and exposure to PFAS during pregnancy and early childhood can result in adverse health impacts. The Government of Canada has also found that PFAS can affect multiple organs and systems in the body including the liver, kidneys, thyroid, immune system, nervous system, and more.
How can I find out if PFAS are in my water?
You can get a fast, accurate reading of your water’s PFAS levels with our low-cost, easy-to-use test kit. Simply request your kit online, use it to gather your sample, and mail it to our lab. Once we receive your kit, you’ll get results in just 10 business days.
Will switching to bottled water help me avoid PFAS?
Unfortunately, studies have shown that there is at least a chance of PFAS contamination in bottled water. DIY solutions like boiling your water or using a standard pitcher filter also don’t provide adequate protection from PFAS. That’s why we recommend scheduling a free consultation and considering a certified solution from Culligan to keep your water safe and clean.
What’s the difference between a whole home filter and an RO system for PFAS?
While both systems protect your water from PFAS, where they’re installed and how much of your home’s water are treated varies. A whole home filter is installed where water enters your home, so all the water flowing through your home is treated for PFAS. A reverse osmosis system with Total Defense is connected to one tap, typically in your kitchen, and provides comprehensive protection from 90+ contaminants including PFAS.
How can I know which system is right for my home?
Schedule a free consultation with your local Culligan experts. They’ll provide personalized recommendations for safeguarding your home’s water – and solving any other water challenges you’re experiencing – based on your needs and your budget.
Can I reduce other contaminants in my drinking water, too?
Absolutely. Culligan’s RO systems reduce more than 90 contaminants like lead, arsenic, bacteria, and microplastics in your drinking water and can be customized with additional filters to combat specific concerns.
