10 Best Pool Sand Filters 2025 in the United States

The INTEX QX2100 Krystal Clear Sand Filter Pump & Saltwater System is a versatile option for keeping above-ground pool water clean and clear. Catering to pools up to 8,500 gallons, this system offers a good balance of efficiency and cost-effectiveness. One of its main strengths is the use of sand as a filter media, which is affordable and only needs replacing every five years with regular backwashing, making it low maintenance.

The advanced filtering system with six cleaning functions ensures thorough cleaning and water circulation, contributing to crystal-clear water quality with a pump flow rate of 2,100 gallons per minute. The system's 24-hour digital timer adds convenience by automating the cleaning schedule, and it includes useful accessories like connector hoses and a power cord with built-in GFCI for safety. The HydroAeration Technology further enhances water clarity and freshness, making the swimming experience more enjoyable.

However, the system's plastic build may raise durability concerns for some users, and its weight of about 51 pounds makes it relatively heavy to move and install. Additionally, while the maximum lifting height of 25 feet may be adequate for most above-ground pools, it could be a limitation for larger setups. Nonetheless, this product is ideal for pool owners seeking a robust and easy-to-use filtration system with minimal chemical use.

The Intex Sand Filter Pump & Saltwater System is designed for above-ground pools up to 15,000 gallons, making it suitable for medium to large-sized pools. One of its main advantages is cost efficiency, as sand is a relatively inexpensive filter media that requires replacement only every five years with regular backwashing. The advanced filtering system is capable of handling a high flow rate of 2,650 gallons per minute, which ensures thorough cleaning through its six functions: filter, backwash, circulation, rinse, recirculate, and system closing.

The 24-hour digital timer adds convenience by automating the pump's operation, making it easy to maintain a clean pool without constant manual intervention. Additionally, the HydroAeration Technology improves water circulation, clarity, and freshness, enhancing the overall swimming experience. The package includes necessary accessories like connector hoses, an inlet fitting, and a long power cord with safety features.

However, the system is on the heavier side, weighing 50 pounds, which might be a consideration for some users in terms of installation and handling. Additionally, the device is made of plastic, which might raise concerns about its long-term durability. Given its features, this product is ideal for pool owners looking for an efficient and relatively low-maintenance filtration system that combines both sand filtering and saltwater capabilities.

The Intex 26651EG sand filter pump is designed for above ground pools up to about 19,600 gallons, making it a solid choice if you have a medium to large pool. It features a strong flow rate of 3,000 gallons per hour, which helps keep your pool water circulating and clean efficiently. The built-in 24-hour automatic timer with preset cycles adds convenience, so you don’t have to manually turn it on or off. Installation is straightforward, requiring just hose connections, which is great if you want a hassle-free setup.

The pump uses Intex’s HydroAeration technology, which improves water clarity by increasing oxygen at the surface—a nice bonus for maintaining fresh water. The construction is mainly plastic, which keeps the unit lightweight (48 pounds) and resistant to rust, but may not feel as durable as metal models.

This model is an affordable, user-friendly option with solid performance for above ground pools, though those looking for a heavy-duty or high-end filter might find it somewhat basic.
