10 Best Sand Filter For Inground Pools 2025 in the United States

The Swimline Hydrotools 19-inch sand filter pump is a solid choice for small to medium inground pools up to 19,000 gallons. Its 19-inch tank size is larger than many basic models, allowing it to hold a substantial 175 pounds of sand, which supports efficient water filtration and reduces the frequency of sand replacement—typically about every five years depending on pool use. The pump is rated at 0.9 THP (approximately 1 horsepower) and can move up to 4,500 gallons per hour, offering a good flow rate for thorough pool cleaning without being overly loud, thanks to its low-noise design.

Users will appreciate the 6-way multi-port valve, which simplifies switching between important functions like filtering, backwashing, rinsing, and winterizing, making maintenance easier even if you're not a pool expert. The build quality includes a double-reinforced tank that should provide decent durability, though the product's weight (around 58 pounds) means it’s fairly solid but also somewhat bulky to move around. The package includes everything needed for quick setup, which is a plus for beginners.

Some users mention that because it’s made in China, certain parts might not feel as premium as more expensive brands, and the warranty is limited to one year. Maintenance is straightforward but requires regular backwashing to keep the sand effective and the water clear. This filter works well both as a standalone set or as a replacement for other brands, adding versatility. This unit provides a dependable, user-friendly option for pool owners seeking a balance between performance, ease of use, and cost, especially suitable if you have a pool under 19,000 gallons and want a quiet, efficient filter.

The XtremepowerUS 24" Sand Filter System offers robust cleaning capabilities, suitable for inground pools up to 29,400 gallons. Its 7-way multi-port valve allows for versatile operation modes including filtering, backwashing, and rinsing, which simplifies maintenance tasks. The filter boasts a commendable flow rate of up to 3,000 gallons per hour, enhancing the efficiency of water circulation and dirt removal.

The internal pipe with a 1.5" diameter ensures smooth water flow, while the built-in drain aids in easy winterizing and servicing procedures, making it convenient for seasonal pool maintenance. Additionally, the pressure gauge included with the tank provides essential monitoring for safe operation. However, the system requires a separate pump to function, which could be an additional expense to consider.

The build quality is solid, designed to withstand various weather conditions, and features brass inserts for longevity, although the product is relatively heavy at 43.3 pounds, which might be cumbersome for some users to handle. While the filter accommodates a substantial 300 pounds of media sand, its dimensions make it slightly bulky, potentially posing a challenge in smaller spaces. Despite these minor drawbacks, the XtremepowerUS Sand Filter System stands as a well-rounded option for inground pool owners seeking efficient filtration combined with ease of maintenance, provided they have space to accommodate its size.
