Brondell Circle RF-20 Replacement Filter Set (3) - RF-20
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. Included with every three-filter pack is a new replacement battery to reset the faucet LED filter change indicator.

The Four Stage H2O+ Circle Reverse Osmosis Water Filtration System (RC100):
Stage 1: SEDIMENT FILTER (RF-20): The sediment filter reduces particulate materials such as sand, rust and fine particles from the water supply. The first stage also acts as a pre-filter, protecting and extending the life of the following filters. Recommended replacement is every six months.
Stage 2: PRE-CARBON PLUS FILTER (RF-20): This second stage filter significantly reduces harmful VOCs, chlorine and soluble contaminants, which can damage the RO Membrane filter. Recommended replacement is every six months.
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 is every 24 months.
Stage 4: POST CARBON BLOCK FILTER (RF-20): As the final stage in the filtration process, the post carbon block filter further reduces any lingering water contaminants such as chlorine and volatile organic compounds (VOCs), improving the overall taste and odor of the dispensed water. Recommended replacement is every six 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.
