Pool Filter Buyer’s Diary: How I Chose Sand, Cartridge, or DE

Follow the journey of choosing a pool filter. Compare sand, cartridge, and DE filters with pros, cons, and maintenance needs.

Choosing a pool filter felt overwhelming at first. Sand, cartridge, DE — every guide seemed to contradict the last. Here’s the journey I went through, what I learned, and how I made the final decision.

Step 1: Understanding Options

  • Sand: Cheapest, easy to maintain, filters down to 20 microns.
  • Cartridge: Mid-range cost, filters to 10 microns, no backwashing needed.
  • DE: Best filtration (3–5 microns), but highest maintenance.

Step 2: Talking to Other Owners

Forum threads leaned heavily toward cartridge for simplicity, while old-school owners swore by sand’s reliability. DE was praised for clarity but groaned about during cleaning.

Step 3: Factoring My Lifestyle

I didn’t want to handle messy DE powder or backwash constantly. Cartridge fit my schedule better.

Final Decision

I chose a large cartridge filter. The upfront cost was higher, but I valued the low-maintenance routine.
