Buying Guide
Key purchase considerations when selecting a sand filter for an inground pool help ensure you choose a system that matches your pool size, usage, and maintenance preferences. The following points cover essential factors, from sand composition to installation compatibility and ongoing care.
- Filter compatibility and tank design: Verify that the filter tank and bed size fit your pool’s plumbing and space. Top-mount units are common for inground setups, while some homeowners prefer side-mount configurations for specific installations.
- Sand type and grain size: Most systems use silica-based filter sand with angular grains. Uniform grain size reduces channeling and improves backwash efficiency. Avoid sands with excessive fines that can clog the bed.
- Filtration efficiency and flow: Consider filtration media that promotes even water distribution, consistent flow, and minimal backwashing. Underdrain design and lateral geometry (360° or multi-lateral) can impact performance and maintenance intervals.
- Pool size and water volume: Match the filter’s capacity and flow rate to your pool gallons. Larger inground pools may require higher-flow systems or 24-inch beds to maintain clear water with less frequent backwashing.
- Maintenance and backwash cycle: Assess how easy it is to backwash, drain, and replace media. Some filters include built-in drains and gauges to simplify maintenance and monitoring.
- Durability and weather resistance: Look for corrosion-resistant tanks and robust construction designed to withstand outdoor conditions. All-weather materials extend the life of the filter in varying climates.
- Cost versus longevity: While initial price matters, evaluate long-term costs related to backwashing water usage, energy consumption, and replacement frequency. A higher-quality sand and tank combination often reduces ongoing maintenance costs.
- Installation and compatibility: Confirm that fittings, hoses, and piping match your existing setup (commonly 1.5″ connections for residential filters). Some models include built-in drains or gauges to aid installation and operation.
