Pool Sand Filter vs. Cartridge Filter: The Ultimate Guide
Trying to choose between a pool sand filter and a cartridge filter? Both are powerful choices for a sparkling clean pool. This guide lays out the facts on each swimming pool sand filter and cartridge system to help you decide.
Two Paths to Crystal Clear Water
An inefficient filter leads to cloudy water. Both Water TechniX pool media filter systems and cartridge filter systems are designed to deliver a pristine pool you can be proud of.
Media vs. Cartridge: At a Glance
| Feature | Pool Media Filters (Sand/Glass) | Pool Cartridge Filters |
|---|---|---|
| Filtration Level | Good: A pool filter with sand traps debris down to 20-40 microns. A glass pool filter improves that to 5-10 microns. | Excellent: A cartridge filter traps debris down to 10-20 microns, capturing finer particles. |
| Maintenance | Low-frequency: Requires 'backwashing' every 4-8 weeks, a 5-10 minute process that cleans the pool sand. | Less frequent, but more hands-on: Requires removing and hosing down the cartridge every 3-6 months. |
| Water Usage | Uses a significant amount of water during backwashing to flush out debris from the pool filtration sand. | Very water-efficient. No backwashing means minimal water loss during cleaning. |
| Upfront Cost | Generally a higher initial investment for the sand filter unit and media. | Typically a lower initial cost for the cartridge filter unit. |
| Ongoing Costs | Pool sand for pool filter needs replacement every 3-5 years. Glass media lasts up to 10 years. | Cartridge elements need replacement every 1-3 years, depending on use. |
| Best For | Larger pools, pools with heavy debris loads, and owners who prefer lower-frequency maintenance. A great sand filter for above ground pool use as well. | Small to medium pools, eco-conscious owners, and areas with water restrictions. |

Both systems provide excellent water clarity. Cartridge filters can trap finer particles (10-20 microns) than a standard pool filter with sand (20-40 microns). However, upgrading a pool media filter with high-quality glass pool filter media allows it to capture particles as small as 5-10 microns, giving it the edge in filtration performance.
For sand filters, pool sand for pool filter typically lasts 3-5 years, while glass media can last up to 10 years. For cartridge filters, the pleated cartridge element usually needs to be replaced every 1-3 years, depending on pool usage and cleaning frequency.
It depends on your preference. A pool media filter requires more frequent but quicker maintenance (backwashing for 5-10 minutes every month or two). A cartridge filter requires less frequent but more hands-on maintenance (removing and hosing down the cartridge for 15-20 minutes a few times a year).
Yes, you can. Switching from a sand filter to a cartridge filter is a relatively straightforward plumbing job. It's a popular choice for those looking to conserve water. Likewise, you can also switch from a cartridge to a media filter if you prefer lower-frequency maintenance.
