Give your family the gift of reliably clean drinking water right from the tap with the Carbon & Claryum® Filter Replacements. As the certified replacement filters for the A.O Smith Clean Water Filter with RO Boost, these filters are designed to seamlessly continue providing the superb contaminant removal you’ve come to expect. Don’t settle for knock-off brands – rely on the Carbon & Claryum filters to keep your water optimally clean and healthy.

Advanced 5-Stage Filtration

The Carbon & Claryum filters utilize a 5-stage filtration process to reduce up to 99% of 88 different contaminants from your water. This includes dangerous pollutants like:

  • Lead
  • Mercury
  • Asbestos
  • Pesticides
  • Pharmaceuticals
  • Chlorine
  • And more

Stage 1 features a heavy-duty sediment filter that traps particles like dirt, silt, and rust. Stage 2 utilizes an extruded carbon block filter to reduce chlorine taste and odor, as well as other common water contaminants.

The proprietary Claryum® filter in stage 3 is what really sets these filters apart. Claryum’s powerful filtration media combines activated carbon with a phosphate-free scale inhibitor to prevent scale buildup. It also reduces a wide range of contaminants you can see, smell, and taste, as well as those you can’t.

Stages 4 and 5 polish the water even further with a 0.5 micron carbon block filter and a final 0.2 micron carbon block filter. This ensures the purest, cleanest drinking water possible.

Easy, No-Tools Replacement

Don’t pay a plumber to replace your filters! The Carbon & Claryum filters are designed for quick, easy, no-tools replacement. Simply open your A.O. Smith filter housing and swap out the old filters with the new ones. Detailed installation instructions are included. Most customers report being able to replace their filters in just 10-15 minutes.

And you’ll know exactly when it’s time thanks to the built-in electronic filter life indicator. There’s no guessing or tracking involved. The system automatically counts down your remaining filter life so you know when a new set is needed.

Lasts 6 Months or 365 Gallons

Each set of Carbon & Claryum filters is certified to last for 6 months or 365 gallons – whichever comes first. This ensures you consistently get the superb water filtration and mineral retention you expect over the entire filter lifetime.
