5. Setup and Installation (Filter Replacement)
The Brio 3-Stage Ultra-Filtration Water Filter features an easy drop-and-lock design, making replacement quick and simple. This filter is specifically designed for Brio undersink filtration systems UF100FBLK and UF100FWHT.
Before You Begin:
- Ensure your Brio undersink filtration system is turned off and the water supply to the system is shut off.
- Have a towel or small basin ready to catch any residual water during the filter change.
Filter Replacement Steps:
- Locate the Filter: Open the housing of your Brio undersink filtration system to access the old filter cartridge.
- Remove Old Filter: Gently twist the old filter cartridge counter-clockwise (if applicable) or pull it down to release it from its locked position. Dispose of the old filter responsibly.
- Prepare New Filter: Remove the new Brio RPFUF100F filter from its packaging. Ensure all protective caps are removed.
- Insert New Filter: Align the new filter cartridge with the filter head in the system. Push the filter upwards and then twist clockwise (if applicable) or push firmly until it clicks into the "locked" position. The drop-and-lock design ensures a secure fit.
- Restore Water Supply: Slowly turn on the water supply to the filtration system. Check for any leaks around the new filter.
- Flush the Filter: It is crucial to flush the new filter before first use. Run water through the system for approximately 5-10 minutes to remove any carbon fines or air from the filter. This ensures optimal performance and taste.

6. Operating the Filter
Once installed, the Brio 3-Stage Ultra-Filtration Water Filter operates automatically as water flows through your undersink filtration system. The filter continuously purifies water through its three stages:
- Water first passes through the sediment filter, which captures larger suspended particles.
- Next, the water flows through the carbon fiber filter, where chlorine, tastes, and odors are absorbed.
- Finally, the water is forced through the fine pores of the ultrafiltration membrane, effectively removing microscopic contaminants before it reaches your faucet.
The filter is designed to maintain a consistent flow rate of approximately 2 Liters Per Minute (LPM) under normal household water pressure, providing readily available filtered water.
7. Maintenance
Regular replacement of your Brio 3-Stage Ultra-Filtration Water Filter is essential to maintain optimal water quality and system performance.
Filter Replacement Schedule:
It is recommended to replace the Brio RPFUF100F filter every 6 to 12 months. The exact lifespan of the filter can vary based on several factors:
- Incoming Water Quality: Water with higher levels of sediment or contaminants may shorten filter life.
- Daily Water Usage: Higher water consumption will necessitate more frequent filter changes.
Signs that your filter may need replacement include a noticeable decrease in water flow, a return of unpleasant tastes or odors, or a change in water clarity.
