10 Best Above Ground Pool Filters 2025 in the United States

The Intex C2500 Krystal Clear Cartridge Filter Pump is a solid choice for above-ground pools, especially for those that hold up to 15,200 gallons of water. With a pump flow rate of 2,500 gallons per hour (GPH) and a system flow rate of 1,900 GPH, it ensures efficient water circulation and filtration. This model uses a replaceable Type B filter, which simplifies maintenance, as you can easily swap out old filters for new ones.

The included Hydro Aeration Technology enhances water clarity and increases negative ions, contributing to a cleaner swimming environment. Installation is straightforward, and the pump's double-insulated design, along with sediment flush and air release valves, make it user-friendly. Additionally, the built-in ground fault circuit interpreter adds a layer of safety.

The automatic timer with preset cycles from 2 to 12 hours is another convenient feature that helps manage operation times and energy usage. However, the pump runs on 120 volts and consumes 120 watts, which might be a consideration for those mindful of energy efficiency. Its plastic construction might not appeal to everyone, but it keeps the weight manageable at 19.56 pounds, making the unit easy to handle. This filter pump is ideal for pool owners looking for improved water quality and ease of use without diving too deep into technical complexities.

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 26637EG C1000 Cartridge Filter Pump is designed for above-ground pools up to 6,000 gallons, making it a good fit for small to medium-sized pools. It uses a cartridge filter system, which is straightforward to maintain since the filter cartridge is easy to clean and should be replaced about every two weeks to keep the water clear and fresh. With a pump flow rate of 1,000 gallons per hour (GPH), it provides solid circulation to help keep your pool clean, although the actual system flow rate in the pool is around 750 GPH, which is typical for this size of filter. The pump features Intex’s HydroAeration Technology, which not only circulates water but also improves water clarity and quality by increasing oxygen levels.

Installation is simple, as you mainly need to connect the hoses and plug it in, which is convenient for those without much technical experience. On the downside, while the filter capacity is suitable for its target pool size, it requires regular cartridge changes, which adds ongoing maintenance and cost. Also, though the product is designed with safety and durability in mind, it is made of plastic, which may not be as long-lasting as heavier-duty materials. Energy efficiency is not specifically highlighted, so it might not be the best choice for users looking to minimize electricity use.

This filter pump represents a practical, easy-to-use option for typical above-ground pool owners who want good water clarity without complicated upkeep, though potential buyers should consider the ongoing cartridge maintenance and moderate energy consumption.
