10 Best Cartridge Filters For Pool Pumps 2025 in the United States

The Intex C1000 Krystal Clear Cartridge Filter Pump is a solid choice for owners of above ground pools up to 6,000 gallons. It offers a decent flow rate of 1,000 gallons per hour, which effectively circulates and filters pool water to keep it clear. The use of HydroAeration technology is a nice bonus, enhancing water circulation and adding negative ions that can improve water freshness.

Its cartridge filter system is straightforward, using Type A cartridges that are easy to clean and replace, with recommended changes approximately every two weeks to maintain good filtration. The Dacron paper filter is designed to trap common pool debris, making it suitable for regular pool maintenance. The pump is lightweight and compact, which aids in easy installation and handling. Ongoing maintenance costs should be considered due to cartridge replacement frequency.

Durability is good given Intex’s reputation for quality, but the plastic build means it should be handled carefully to avoid damage. For those seeking a user-friendly, affordable pump that balances performance with simple upkeep, this model fits well—especially for smaller above ground pools. Users with larger pools or needing ultra-fine filtration might prefer more powerful or specialized options.

The Intex C530 Krystal Clear Cartridge Filter Pump is designed for above ground pools up to 3,800 gallons, making it a good choice for smaller to medium-sized pools. It offers a decent flow rate of 530 gallons per hour (475 GPH in the pool system), which is adequate for maintaining clean water and improving circulation. The pump uses Type A filter cartridges made of Dacron paper, which provides effective filtration and is relatively easy to clean, though these cartridges need replacement approximately every two weeks, which might be a bit frequent for some users. One notable feature is Intex's Hydro Aeration Technology, which enhances water clarity and quality by increasing oxygen levels.

Installation is straightforward with simple hose connections and plug-in power, so it’s user-friendly for those without technical skills. The pump is lightweight and compact, but since it's made primarily of plastic, it may not be as durable as more heavy-duty models. Intex supports the product with a 2-year limited warranty and responsive customer service, adding peace of mind.

This pump serves as a solid, affordable option for typical above ground pool owners who want easy setup and decent water cleaning performance without dealing with complex maintenance.
