10 Best Above Ground Pool Filters 2025 in the United States

The Hayward W3S244T ProSeries Sand Filter is a solid choice for above-ground pools, especially if you want reliable and low-maintenance filtration. It uses a sand filter type, which is known for effectively trapping debris without frequent filter changes. The 24-inch top-mount design and the multilateral underdrain with self-cleaning slotted laterals help maintain an even flow of water, contributing to efficient filtering and backwashing. This means the filter can clean itself more easily, reducing the effort you need to spend on maintenance. The integral top diffuser also helps spread water evenly over the sand, which improves filtering performance.

In terms of build, the corrosion-proof tank is made from durable polymer material, so it stands up well to weather and pool chemicals over time. The 6-position control valve is user-friendly, letting you switch between filter settings with ease. It also includes a large drain to help with quick winterizing or servicing, which is a helpful feature for seasonal pools.

The filter weighs 48 pounds and has a footprint of about 22.6 inches square, so make sure you have enough space for installation. This model offers dependable filtering power and easy upkeep for your above-ground pool.

The Hayward W3C12002 StarClear Plus is a cartridge-type pool filter designed for above-ground pools, offering a large 120 square feet filter capacity. This means it can handle a good volume of water before needing cleaning, making it suitable for medium to larger pools. Its cartridge design is easy to maintain since you just remove and rinse it, which avoids buying replacement sand or DE powder.

The single-piece injection-molded body gives the filter a sturdy and corrosion-resistant build, so it should last well in outdoor conditions. The flow rate is supported by its precision-engineered core and strong gasketed end caps, allowing water to pass through efficiently without leaks. It’s also convenient to use with a single-locking knob and rotatable filter head for quick access when cleaning or checking pressure. Plumbing options are flexible with multiple connection sizes, which helps in fitting various pool setups.

Although it is energy-friendly due to its efficient flow design, actual power usage depends on your pool pump. Cartridge filters generally require more frequent cleaning compared to sand filters, which might not suit those seeking very low-maintenance options. This filter serves as a solid choice for anyone wanting an effective, reliable cartridge filter that’s straightforward to service and built to last.

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.
