Rainfresh system guide: choosing the right setup ▾
Choose by where you want filtered water
- Faucet filters: the Instapure F5C (chrome) and F-2WU (white).
- Undersink drinking water systems: UC205, UCS2 and the QS1X and QS2X Twist systems.
- Whole house or undersink: FC100 and FC150 (5 micron) systems, or the FC005 housing on its own.

- UV: the R830 UV disinfection system and the R519 UV purification system, rated 5 GPM for up to 2 bathrooms.
Installation
Check the system's flow rating and fittings against your plumbing before you order. UV systems also need an electrical supply. Follow Rainfresh's installation instructions, and use a licensed plumber or electrician if the job involves cutting into your water line or new wiring.
Keeping it running
Each system takes specific replacement cartridges, so note your model and follow Rainfresh's schedule for changing cartridges and, on UV systems, the lamp.
