Does the PUR water filter remove fluoride? Discover the importance of fluoride removal and what PUR filters can and cannot do. When it comes to clean, safe drinking water, most people turn to popular brands like PUR for convenience and reliability. PUR filters are known for removing a wide range of contaminants—but one question many customers have is:
👉 Does the PUR water filter remove fluoride?
In this in-depth guide, we’ll explore everything you need to know about PUR filters, what they do (and don’t) remove, why fluoride is such a hot topic, and which filtration methods are best if you’re looking to remove fluoride from your water.
What Is Fluoride and Why Is It in Tap Water?
Fluoride is a mineral found naturally in the earth’s crust and in some water sources. Since the 1940s, many municipalities have added fluoride to drinking water to prevent tooth decay.
While it does have dental benefits, some health experts and consumers raise concerns about excess fluoride exposure, linking it to:
- Thyroid problems
- Neurological effects
- Dental fluorosis (white spots on teeth)
- Skeletal fluorosis in rare cases
Because of these potential risks, many people want to reduce their fluoride intake by using water filters at home.
Understanding PUR Water Filters
PUR water filters come in various forms:
- Faucet-mount filters
- Pitchers
- Dispensers
- Replacement cartridges
These filters use activated carbon and ion exchange to remove common water contaminants like:
- Chlorine (taste & odor)
- Lead
- Mercury
- Certain pesticides and industrial pollutants
- Pharmaceuticals
PUR filters are NSF-certified for reducing over 70 contaminants, making them a solid choice for everyday water purification needs.
But Do PUR Water Filters Remove Fluoride?
No, PUR water filters do not remove fluoride.
PUR’s filtration technology is not designed to filter out fluoride ions, which are very small and require a specialized filtration method. PUR filters are excellent at removing many impurities, but fluoride is not one of them.
According to PUR’s own documentation and third-party tests:
“PUR filters do not remove fluoride from water.”
Why Can’t PUR Remove Fluoride?
Fluoride is a naturally occurring mineral in water and is inorganic, making it difficult to filter using standard carbon-based systems. PUR filters rely on:
- Activated carbon: Good for chlorine, taste, odor, and VOCs
- Ion exchange: Targets metals like lead and mercury
These materials do not bond with fluoride ions, so fluoride passes through the filter and remains in your drinking water.
How Can You Remove Fluoride from Water?
If removing fluoride is your goal, you’ll need a more advanced system. Here are three proven methods:
✅ 1. Reverse Osmosis (RO) Systems
How it works: Water is forced through a semi-permeable membrane that filters out most contaminants, including fluoride.
- Removes 95–99% of fluoride
- Also removes heavy metals, chlorine, arsenic, and more
- Ideal for under-sink use
Perfect for: Health-conscious families and homes with high fluoride levels
✅ 2. Activated Alumina Filters
How it works: Fluoride binds to the porous surface of activated alumina (a form of aluminum oxide), effectively removing it.
- Removes up to 90% of fluoride
- Often used in countertop or under-sink filters
- Requires regular replacement
Perfect for: Budget-conscious users wanting targeted fluoride removal
✅ 3. Water Distillation Units
How it works: Boils water into vapor, leaving contaminants behind, then condenses the vapor back into clean water.
- Removes nearly all impurities including fluoride
- No filter replacements needed
- Takes longer than other methods
Perfect for: Homeowners who prioritize ultra-pure water
PUR vs Fluoride-Removing Filters: A Side-by-Side Comparison
| Feature | PUR Filters | Reverse Osmosis | Activated Alumina | Distillers |
|---|---|---|---|---|
| Removes Fluoride | ❌ No | ✅ Yes | ✅ Yes | ✅ Yes |
| Price Range | 💲 | 💲💲💲 | 💲💲 | 💲💲💲 |
| Installation Required | ❌ No | ✅ Yes | ⚠️ Maybe | ❌ No |
| Filter Speed | Fast | Moderate | Slow | Very Slow |
| Maintenance Level | Low | Medium | Medium | Low |
Should You Be Concerned About Fluoride?
Whether fluoride is harmful or helpful depends on your perspective and individual needs. While health organizations like the CDC and WHO support water fluoridation for dental health, many people are concerned about:
- Long-term exposure
- Accumulated fluoride from toothpaste, food, and water
- Effects on children and pregnant women
If you’re already using fluoridated toothpaste and consuming processed foods, your fluoride exposure may be higher than you think.
