Quick answer: Cartridge filtration suits smaller, simpler pools; sand filtration suits more stable seasonal operation and larger water volumes. Volume, load, and service convenience are what decide.
Filtration is the foundation of clean water. When choosing, people often focus only on price, but performance, maintenance, spare parts availability, and actual bather load matter more.
Cartridge Filtration
Cartridge filtration tends to be cheaper and simple, but it requires regular cleaning and can quickly reach its limit under heavier load.
- lower purchase price
- simple handling
- suitable for smaller pools
- more frequent cartridge cleaning
Sand Filtration
Sand filtration is a more robust solution for seasonal operation, but it needs correct sizing and regular backwashing.
- suitable for larger volumes
- easier long-term operation
- option to add a flocculant depending on the system type
- requires backwashing and media checks
How to Decide
Have the pool volume, flow rate, and expected load calculated. Weak filtration increases chemical consumption and stress levels.
- water volume
- number of bathers
- available space
- maintenance costs
