Frequently Bought Together
The UPF-S20L whole house filtration system is commonly paired with our Ultrefina UWS-FF2, Smart HE Whole House Water Softener for homes experiencing hard water and scale buildup.
For homeowners looking for salt-free conditioning technology, the HydroShield Total: Ultrefina salt free softener system is an excellent complementary solution.
For cleaner and better-tasting drinking water at the kitchen tap, many homeowners pair this system with our URO-T09 reverse osmosis system to help reduce chlorine, sediment, heavy metals, PFAS, and unwanted odors from drinking water.
For homeowners looking for a more economical and green option, the URO-T09A Non-Electric Reverse Osmosis System delivers the same advanced contaminant reduction—including chlorine, sediment, heavy metals, PFAS, and unwanted odors—while requires no electricity.
Frequently Asked Questions
1. What contaminants does does it remove?
The UPF-S20 helps reduce sediment, sand, rust, dirt, silt, and other suspended particles commonly found in municipal and well water supplies. By removing these contaminants, it helps improve water clarity and protects plumbing fixtures and appliances from buildup.
2. Will it protect my water softener and reverse osmosis system?
Yes. The UPF-S20 acts as a pre-filtration system that helps prevent sediment and particulate matter from reaching downstream equipment. This can help improve the performance and lifespan of water softeners, reverse osmosis systems, water heaters, and other water treatment equipment.
3. Is it suitable for municipal water or well water?
Yes. The UPF-S20 is suitable for both municipal and well water applications where sediment, rust, sand, and suspended particles are present. It provides an effective first stage of filtration before water enters the home's plumbing system.
4. How often should I replace the filter?
The UPF‑S20’s stainless steel filter core doesn’t need replacement. Just perform a routine manual flush to clear sediment and maintain flow.
If you use optional cartridges, replacement depends on water quality and usage:
-
Sediment filter: every 3–6 months
-
CTO carbon filter: every 6–12 months
Replace sooner if you notice a pressure drop or the cartridge looks heavily loaded with sediment.
