COMPATIBILITY & APPLICATIONS

System Compatibility

This filter kit is engineered as a direct replacement for RainSoft Ultrafiner II UF22 and RainSoft 21179 reverse osmosis systems. All filters are dimensioned and constructed to OEM specifications, ensuring proper flow rates, housing fit, and filtration performance. The 50 GPD TFC membrane provides efficient rejection of total dissolved solids, heavy metals, nitrates, and fluoride, while the dual carbon block filters protect the membrane and polish final output water. Suitable for residential point-of-use applications where consistent, high-quality drinking water is required.

💧
Replace carbon filters annually even if water tastes fine. Chlorine breakthrough damages RO membranes long before you notice flavor changes, and a $30 carbon filter protects a $60 membrane. Track your installation date.
