The Intex Sand Filter Pump & Saltwater System is designed for above-ground pools holding up to 15,000 gallons, making it a good fit for medium to large backyard pools. It uses sand as the filter media, which is cost-effective and only needs replacement roughly every five years with proper maintenance. Its flow rate is about 8,140 liters (or 2,650 gallons) per hour, which is strong enough to keep pool water clean and clear efficiently. The multi-function valve allows for six cleaning modes including filter, backwash, and rinse, which helps maintain the system with ease.

Also, the HydroAeration Technology improves water circulation and freshness by adding bubbles, enhancing water clarity.

It comes with necessary hoses and safety features like a built-in GFCI power cord, supporting safe and straightforward setup.

The plastic build requires care to avoid cracks or damage, and users should confirm their pool size falls within the recommended range to ensure optimal performance.
