Starting our "This or That" series with an age old pool question...
🏊♂️ Pool filter dilemma: Sand vs Cartridge — which one actually wins for your backyard oasis?
Sand Filters
Pros:
✅ Cheaper upfront (often $300–$800 for the system)
✅ Super low-maintenance — just backwash every few weeks
✅ Very durable — sand media lasts 5–7+ years before needing replacement
✅ Handles large pools and heavy debris loads like a champ
✅ Forgiving if you forget maintenance for a bit
Cons:
❌ Only filters down to ~20–25 microns → water is clear but not crystal clear (more visible fine particles/pollen sometimes)
❌ Uses more water (backwashing wastes 50–100+ gallons each time)
❌ Higher energy use (needs more pump pressure to push through sand)
❌ Backwash water can be messy/dirty to deal with
Cartridge Filters
Pros:
✅ Filters finer particles (~10–15 microns) → noticeably clearer, sparkling water (great if you hate seeing tiny specks!)
✅ More energy-efficient (lower pressure = pump works less = lower electric bill)
✅ No backwashing → saves thousands of gallons of water per season
✅ Easier on the environment and your wallet long-term for water usage
✅ Quieter operation in many setups
Cons:
❌ Higher initial cost (usually more expensive than sand)
❌ Requires more hands-on maintenance — hoses off the cartridges every 1–4 weeks (can be messy if you're not careful)
❌ Cartridges wear out and need replacement every 1–3 years (~$50–$200+ each depending on size)
❌ Can clog faster in very dirty/heavy pollen areas if not cleaned regularly
Bottom line for most people:
Want set-it-and-forget-it simplicity + lower upfront cost? → Go sand
Obsessed with super clear water and don't mind a little cleaning? → Go cartridge
