10 Best Above Ground Pool Filters 2025 in the United States

The Intex SX2100 Krystal Clear Sand Filter Pump is designed for above-ground pools, bringing several benefits to pool maintenance. It features a robust 2100 GPH pump flow rate, which ensures efficient water circulation and filtration. This makes it suitable for pools up to 12,800 gallons, which is a decent capacity for most residential above-ground pools.

The built-in 24-hour timer with preset cycles between 2 to 12 hours offers convenience, allowing for automatic operation and reducing the need for manual intervention. This feature can be particularly helpful for those who prefer a low-maintenance solution. Installation is straightforward, requiring only the connection of hoses and plugging in, though some partial assembly is needed. The filter pump leverages HydroAeration Technology, which enhances water clarity and circulation, while also contributing to increased negative ions on the water surface, which can improve the pool experience.

However, it does have some drawbacks. The pump is corded electric, which may limit placement options and requires proximity to a power source. Additionally, the physical dimensions of the pump are relatively large, at 22.25 inches long, 15.38 inches wide, and 23.25 inches high, which could be a consideration for those with limited space around their pool area. While it is designed to be easy to clean, sand filter maintenance can still be more involved compared to other types of filters like cartridge filters. Lastly, the pump’s weight at nearly 36 pounds might make it cumbersome to move around if needed. Despite these minor downsides, the Intex SX2100 offers a blend of performance, convenience, and innovative features, making it a solid choice for those seeking a reliable and efficient sand filter pump for their above-ground pools.

The Intex Sand Filter Pump & Saltwater System is designed for above-ground pools holding up to 15,000 gallons of water. A notable strength of this system is its use of a sand filter, which is known for cost efficiency and durability. Sand, as a filter media, is inexpensive and only requires replacement approximately every five years with regular backwashing, making it a low-maintenance option.

The system boasts an advanced filtering setup with six specific cleaning functions, including filter, backwash, rinse, and circulation. With a pump flow rate of 2,650 gallons per minute, it ensures a consistent and robust water flow, ideal for maintaining cleanliness in larger pools. The included HydroAeration Technology enhances water clarity and freshness, leading to a cleaner swimming environment.

A convenient feature is the digital control panel with a 24-hour timer, allowing users to automate the system's operation, which can run up to 12 hours a day. This ease of use is a significant benefit for busy pool owners. However, there are some considerations to keep in mind. The system is corded electric, relying on a 25ft power cord, which may limit placement options near the pool. Also, with a weight of 50 pounds, installation could require some effort. Users have generally responded positively to its performance, reflected in a 4.3-star rating from nearly 9,000 reviews, indicating satisfaction among many.

This Intex system is well-suited for those with medium to large above-ground pools looking for an efficient and relatively low-maintenance filter system. It may not be ideal for those with smaller pools or those who cannot accommodate the power needs and physical setup.

The INTEX SX1500 Krystal Clear Sand Filter Pump is a sand filter pump designed for above-ground pools, offering a blend of functionality and ease of use. Its standout feature is the innovative Hydroaeration Technology, which enhances circulation and filtration, improves water clarity, and boosts negative ions at the water's surface, potentially making the swimming experience more pleasant.

With a pump flow rate of 1500 GPH, it can efficiently cater to pools up to 8,400 gallons, making it suitable for medium to large-sized pools. The built-in 24-hour timer with adjustable cycles adds convenience, allowing users to automate operation, reducing manual maintenance efforts. Installation is straightforward, with a simple hose hookup and plug-in system, though some assembly is required.

In terms of maintenance, sand filters generally require less frequent cleaning than cartridge filters, which might appeal to those seeking low-maintenance solutions. However, sand replacement and backwashing are necessary periodically. While the pump is corded and operates at 120 volts, it doesn't specifically highlight energy efficiency, which might be a consideration for energy-conscious users. The pump's durable design and adherence to safety standards reflect Intex's commitment to quality and longevity. Despite these strengths, the unit's weight at 24.7 pounds might be cumbersome for handling or repositioning. It's an affordable choice for those prioritizing reliable filtration and easy setup, though users should consider the initial setup effort and ongoing maintenance needs before purchase.
