Top-10 Sand Filter For Inground Pools
Loved in the USA

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 Hayward W3S244T ProSeries Sand Filter is a 24-inch top-mount filter for inground pools. One of its major strengths is the efficient multilateral underdrain assembly, which includes self-cleaning 360° slotted laterals that ensure balanced flow and effective backwashing. Additionally, the integral top diffuser helps distribute water evenly over the sand media bed, enhancing filtration performance.

The filter tank is made of a rugged, colorfast polymeric material, making it corrosion-proof and durable across various weather conditions. Another convenience is the 6-position Hayward VariFlo control valve, which features an easy-to-use lever-action handle for simple operation of different valve and filter functions.

The large pressure sand/water drain allows for rapid winterizing or servicing, adding to its practicality. However, the filter weighs 48 pounds, which might be cumbersome for some users to handle. Maintenance requirements are generally straightforward with this model, but regular backwashing is necessary to keep it functioning optimally. The Hayward W3S244T ProSeries Sand Filter is best suited for users looking for a reliable and durable sand filter for their inground pool, with easy operation and efficient filtration capabilities.
