First, know your enemy. Fill a clear glass with tap water. Let it sit for an hour. What’s at the bottom? If it’s sandy, get a spin-down. If it’s a fine, cloudy layer, get a pleated or string-wound filter. If there’s nothing at all, then you’re either lucky or lying to yourself.
Second, don’t over-filter right away. Start with a 50-micron filter. If your water still looks like a swamp, drop to 30-micron. If that clogs fast, you need the backwashing system. It’s like Goldilocks, but with sediment and less porridge.
Third, check your flow rate. A filter that slows your water to a trickle is not a filter—it’s a punishment. Most big blue housings handle 10-15 gallons per minute, which is plenty for a standard household. If your well pump screams when you use two faucets, get a larger housing or the backwashing model.

And one more thing: always install a pressure gauge before and after the filter. When the pressure drop hits 10 PSI, it’s time to change the cartridge. Otherwise, you’ll just guess, and guessing leads to burst filter housings. Trust me on this one—I’ve mopped up that mess.
