Product Review

The Circle filters are separated into two replacement filter cycles: the three-filter pack (RF-20) needs to be changed every six months while the RO Membrane filter (RF-40) only needs to be changed every 2 years.

Stage 3: RO MEMBRANE FILTER (RF-40): The RO Membrane filter works by pushing water through a semi-permeable membrane thereby separating H2O molecules from contaminants in the tap water. The powerful RO Membrane filter significantly reduces pollutants such as: heavy metals, cysts, fluoride, arsenic, industrial chemicals and more. Recommended replacement every 24 months.

Brondell water filtration systems are all tested and certified by the Water Quality Association (WQA). Beware of cheap imports and non-certified manufacturer's filtration claims that have not been tested and approved by an authorized agency for water filtration products
