The H2O UCF-02-14-JG is a dual-stage under-sink filter system housing assembly that lets you build a custom drinking water setup using two industry-standard 10-inch x 2.5-inch filter cartridges. Because the cartridges are sold separately, you can choose the filter combination that best meets your water goals, such as sediment reduction, chlorine taste and odor removal, chloramine reduction, fluoride reduction, pH correction, heavy metal reduction, or specialty filtration.
This system is a strong fit for homes and businesses that want flexible under-sink filtration at one faucet without installing a full reverse osmosis system.

How to Choose Cartridges for the H2O UCF-02-14-JG
This system accepts two standard 10-inch x 2.5-inch cartridges, which allows you to build a two-stage setup.
Common cartridge pairings include:
Sediment plus carbon
Use a sediment cartridge first to capture particles, then a carbon cartridge for chlorine taste and odor.
Carbon plus specialty media
Use carbon filtration with a specialty cartridge to achieve a more targeted water-quality goal.
Chloramine reduction setup
Choose cartridges designed for chloramine reduction if your city water uses chloramines and taste or odor is a concern.
Fluoride or arsenic reduction setup
Use specialty cartridges designed for the specific contaminant and confirm the cartridge is appropriate for your water conditions.
pH correction setup
Use a pH correction cartridge when your water test shows a low pH, and you want a targeted adjustment at the drinking water faucet.
DI or high-purity polishing setup
Use DI or specialty polishing cartridges when your goal is lower ion content for a specific application.
