The SmartFlow™ Reverse Osmosis Carbon Block and Advanced Carbon Block Replacements replace Stages 1 and 3 in the SmartFlow™ Reverse Osmosis (AQ-SFRO) and last for 6 months each.
Stage 1: Carbon Block
Reduces chlorine, taste and odor prior to reverse osmosis filtration.
Stage 3: Advanced Carbon Block
The SmartFlow™ Reverse Osmosis is Aquasana's brand-new, high-efficiency reverse osmosis system. This system combines Aquasana's Claryum® filtration technology with reverse osmosis technology to remove up to 99.99% of 90 contaminants, including fluoride, arsenic, lead, chlorine, microplastics, PFOA/PFOS, and more.
The SmartFlow™ Reverse Osmosis boasts one of the highest certified contaminant removal rates of all reverse osmosis systems on the market. In fact, it's certified to reduce 89 more contaminants than Amazon's top-selling RO system is certified to reduce.*
Featuring our patented SmartFlow™ technology, this system provides you with more pure water, less water waste, and longer filter life than the average RO filter. The system also restores healthy minerals that other reverse osmosis systems remove, providing you with optimum health and hydration.
- Filter Life:
- 6 months
- 365 gallons
SmartFlow™ Reverse Osmosis
High-efficiency reverse osmosis system removes up to 99.99% of 90 contaminants including fluoride, arsenic, chlorine, and lead.
How to Replace the SmartFlow™ Reverse Osmosis Carbon Block Filters
Stage 1 (Carbon Block) and Stage 3 (Advanced Carbon Block) filter cartridges should be replaced every 6 months or up to 365 gallons. Stage 2 (SmartFlow™ Membrane) should be replaced every 12 months depending on usage and water quality. For homes with higher water usage and/or poorer water quality, you may need to replace your SmartFlow™ Membrane sooner than every 12 months. Stage 4 (Remineralizer) should be replaced every 6 months depending on usage and water quality.

Reverse osmosis is an incredibly effective method of filtering water, and it works by pushing water through a semi-permeable membrane (a porous block) at a high pressure to remove contaminants. As this pressurized water passes through the membrane, contaminants are left behind and only clean water passes through.
Our reverse osmosis system uses this process, in conjunction with a series of other filters, to increase effectiveness and retain healthy minerals that are often lost during the RO process. Water first passes through our Carbon Block to remove chlorine, taste and odor. Then, the system uses reverse osmosis filtration by pushing water through a semi-permeable SmartFlow™ membrane at a high pressure to remove dissolved solids smaller than 1 micron. Next, our Advanced Carbon Block filter uses ion exchange and sub-micron filtration to remove heavy metals, chemicals including herbicides and pesticides, and other contaminants. Finally, our RO system uses remineralization technology to restore healthy minerals like calcium while improving the pH balance and alkalinity of water for exceptional taste.
TDS, or Total Dissolved Solids, is the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals, but they are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead but selectively retain or replace healthy dissolved solids like calcium. Read more about TDS here.
The SmartFlow™ Reverse Osmosis comes standard with a 6-month Remineralizer designed to replace healthy minerals lost in the reverse osmosis process.
