How It Works

Installation and Ease of Use
Setting up the FS-TFC 5-Stage RO System is relatively straightforward, even for first-time users. It includes all necessary components, such as tubing, connectors, a faucet, and a storage tank. Installation typically takes 1-2 hours, depending on your familiarity with basic plumbing.
The system fits conveniently under most kitchen sinks, measuring just 16 inches in height. Once installed, operation is simple: turn on the dedicated RO faucet, and the system provides clean, purified water on demand. Just keep in mind that, like all RO systems, it does produce some wastewater—approximately three gallons of waste per one gallon of purified water.
Portability and Space Considerations
While not a portable water filter, the FS-TFC 5-Stage RO System is compact enough to fit under most standard kitchen sinks without taking up excessive space. Weighing about 22 pounds, it’s a permanent installation rather than something you’d move around frequently.
If you’re looking for a filtration solution for an RV or a temporary setup, a countertop or tankless RO system might be a better choice. However, for home use, this system’s compact size and under-sink design make it a practical and space-efficient solution.
