Our Pitcher Filter Is Now Certified To Remove 270+ Contaminants (Including Viruses, Perchlorate, & HAA5)

*Update: as of August, 2021, our pitcher filter is certified to remove 365+ contaminants.

Did you know new contaminants regularly sneak into your tap water? 

These pollutants emerge almost daily by treatment and by accident. Look no further than the Chicago suburbs, the Lone Star State, and this handy Business Insider round-up for recent examples of contamination. Chances are your tap water could be contaminated as tens of millions of Americans are affected every year. 

For your safety, we proactively test our filters against hundreds of these existing, emerging, and new contaminants in water. We’re thrilled to share that our latest round of testing revealed amazing results:

Previously certified to remove 232+ contaminants including fluoride, PFAS, and arsenic, our pitcher filter is now certified to remove more than 270 contaminants, including new dangers like viruses, HAA5, and perchlorate. 

It’s a statement of strength, power, and performance — backed by data. 

Whether you’re already part of the Clearly Filtered family or considering upgrading to the most powerful water pitcher on the planet, here’s what you need to know about this incredible news:

Q: Did the filter change?

A: No significant changes were made to our pitcher filter. The performance data confirmed the current filtration technology inside our pitcher filter is already removing 270+ contaminants. That’s why we say: Same filter, better results. 

Q: Are the filters I already have impacted by this?

A: Yes, the filters you already have are now certified to remove 270+ contaminants. Remember, no significant changes were made to our pitcher filter prior to testing. The bottom line is the filter(s) you already have now perform better than ever.

Q: Does my filter still remove all of the contaminants it did before?

A: Yes. Your filter still removes all of the contaminants it was previously certified to remove—including fluoride, arsenic, and PFAS—with the exception of a select few contaminants that no longer have testing available. We sought out new testing to prove your filter goes above and beyond to eliminate additional threats.

Q: What new contaminants does it remove?

A: The 270 more contaminants it’s now certified to remove are made up of new and noteworthy threats including viruses, HAA5, and perchlorate. Keep scrolling to learn more about each. 

Q: What are viruses?

A: Viruses are tiny disease-causing organisms that can sneak into water supplies and slip by filters undetected. Waterborne viruses can cause the stomach flu, meningitis, and hepatitis.

While the U.S. EPA regulates tap water to help prevent viruses, there’s no guarantee that your water is always virus-free. Remember, typical carbon and charcoal filters do not remove viruses from tap water. Our pitcher filter removes up to 99.9999% of viruses from tap water. Learn more about viruses here.

Q: What is HAA5?

A: HAA5 is a group of harmful disinfection byproducts (DBPs) that form when disinfectants like chlorine interact with natural materials found in water. Long-term exposure to elevated levels of HAA5 has been associated with bladder, colon, and rectal cancer, as well as liver and kidney issues. 

Since the U.S. EPA monitors HAA5 levels as an annual average, HAA5 can exceed EPA-approved levels at any given time. Our filter pitcher removes up to 99.9% of HAA5 from tap water. Learn more about HAA5 here.

Q: What is perchlorate?

A: Perchlorate is a chemical used in rocket fuel, flares, fireworks, and explosives that has been found in drinking water in at least 26 states. The chemical can block the thyroid from taking in iodide, which can lead to hypothyroidism. It can also impact brain development in fetuses and infants. 

There is no national regulation on perchlorate in public drinking water systems nor in bottled water. The NRDC says more than 16 million people may be affected by perchlorate in their tap water. Our filter pitcher removes >96.0% of perchlorate from tap water. Learn more about perchlorate here.

Q: How often do you test your filters?

A: To avoid being limited by a rigid schedule, we seek out new tests as new contaminants emerge. Our proactive approach ensures you can always count on us to protect you and your family from the dangers lurking in tap water.  

Q: How does this impact replacement filters?

A: All pitcher filters — including replacements — are now certified to remove 270+ contaminants.  

Q: Will this impact my filter subscription?

A: Not at all. As a subscriber, you will continue to save 10% on every filter and enjoy free shipping in the U.S.A. If you’re not a subscriber, sign up for free and start saving today.

A: No. You’ll continue to get the same great price on all of our breakthrough water filters and filtration systems when you purchase here
