What Makes a Great Hose-End Hard Water Filter?
Finding the best hard water filter for garden hose comes down to three things: media quality, flow, and capacity. Good media blends use activated carbon and KDF, which reduce chlorine, odor, and some heavy metals. Some blends add softening resins to reduce water spotting.
Flow matters because you don’t want slow fills or weak rinse pressure. Look for filters that keep steady flow under normal pressure. Lastly, capacity is key if you wash cars weekly or fill pools. Larger capacity filters handle more gallons before needing a change.
