Why Aquasana’s new Claryum® under sink water filters matter
Every year, Aquasana surveys Americans about their drinking water concerns — and our Water Quality Survey’s latest results are eye-opening. Nearly nine in ten people say they’re worried about the quality of their unfiltered tap water, especially when it comes to PFAS (“forever chemicals”) and microplastics.
According to the Environmental Working Group, more than 172 million Americans have tap water with detectable levels of PFAS — chemicals believed to be linked to serious health risks like cancer, thyroid disorders, and immune issues.
That’s why Aquasana’s continued innovation in filtration is such a big deal.
Stronger protection at tougher standards
Aquasana was the first filtration brand certified by NSF for reducing PFOA/PFOS (types of PFAS) back in 2016 — and we haven’t stopped improving.
The latest Claryum® under sink filters are now certified to remove up to 99.99% of 78 contaminants, including:
- Lead
- PFAS (PFOA/PFOS) “Forever Chemicals”
- Microplastics
- Pharmaceuticals
- Herbicides
- Pesticides
- Chlorine
- Chloramines
That’s 15 times more contaminants — with up to 7 times faster flow rate — than the leading pitcher filter.
Even better, the systems now meet the new, stricter NSF Standard 53, which requires PFAS reduction down to 20 parts per trillion, compared to the older 70 ppt benchmark.
Designed for your kitchen and your lifestyle
Aquasana didn’t just stop at better performance — they made sure the new systems look great too. The premium metal faucets now come in a matte black finish in addition to chrome, brushed nickel, and oil-rubbed bronze.
And for the first time, there’s a no-faucet option, perfect for homeowners who want to use their own fixture.
Each Claryum® filter set replaces the equivalent of up to 6,000 plastic bottles, helping families cut down on waste while enjoying cleaner, better-tasting water straight from the tap.
The science behind Claryum® filtration
Aquasana’s Claryum® technology uses a five-stage process to filter out harmful contaminants while keeping beneficial minerals like calcium, magnesium, and potassium:
- Activated Carbon – Targets chlorine, taste, and odor and reduces PFAS, microplastics, pharmaceuticals, herbicides, pesticides, VOCs, and more
- Catalytic Carbon – Reduces chlorine-resistant contaminants and further reduces chlorine and chloramines
- Ion Exchange – Captures heavy metals like lead and mercury
- Sub-Micron Filtration – Removes microscopic particles, including cysts and asbestos
- Organic Adsorbent Booster – Further reduces PFAS
All systems are WQA tested and certified to NSF/ANSI Standards 42, 53 (including P473), and 401.
