Under sink water filters
Because under sink water filters are much smaller than whole house systems, they need to be replaced more frequently. Here’s how that breaks down:
- Claryum® 2-Stage: Replace every 6 months or 500 gallons.
- Claryum® 3-Stage: Replace every 6 months or 600 gallons.
- Claryum® 3-Stage Max Flow: Replace every 6 months or 800 gallons.
- Claryum® Direct Connect: Replace every 6 months or every 784 gallons.
- OptimH2O® Reverse Osmosis + Claryum®:
- Carbon and Claryum® filters: Replace every 6 months or 365 gallons.
- Membrane replacement: Replace every 12 months.
- Remineralizer replacement: Replace every every 12 months.

Countertop water filters
Our most compact and no installation filter is our countertop filter system, the Clean Water Machine. The filter will need to be replaced every 6 months and can be swapped out in a matter of minutes.
Shower filters
Our SimplySoft™ coconut shell carbon and Copper-Zinc (KDF) media filtration reduces 90% of chlorine for a cleaner, healthier shower experience. Aquasana’s shower filter replacement cartridges also last approximately six months.
