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

The Hayward W3S310T2 Pool Sand Filter is an excellent choice for inground pools, featuring a sizable 30-inch filter that promises efficient performance. Its multilateral underdrain assembly with self-cleaning 360° slotted laterals ensures balanced flow and effective backwashing, which is ideal for maintaining water clarity.

The filter media is evenly distributed thanks to the integral top diffuser, enhancing the filtration process. The unit is built with a corrosion-proof, rugged polymeric material, ensuring durability and reliable performance across various weather conditions. Maintenance is made easier with the large pressure sand/water drain and the 6-position VariFlo control valve, which simplifies the operation with its lever-action handle.

However, the filter's weight (83 pounds) and size (32 x 32 x 48.3 inches) may require careful consideration for installation and handling. This sand filter is well-suited for users seeking a durable, efficient, and easy-to-maintain solution for their inground pools.

The Hayward W3S270T ProSeries is a 27-inch top-mount sand filter designed for inground pools. Its size is suitable for medium to large pools, offering efficient water flow thanks to a well-designed internal system that ensures even water distribution and balanced backwashing. The filter uses sand as its media, which is common and effective at trapping debris, making pool maintenance easier.

It features a 6-position VariFlo control valve with a lever handle, allowing you to switch between filtering, backwashing, rinsing, and other functions with simple, straightforward operation. The tank is made from rugged, corrosion-proof polymeric material, which holds up well against weather and wear, promising durability over time. Also, a large pressure drain helps with quick servicing and winterizing.

This model is a solid choice for those seeking a reliable, easy-to-use sand filter that balances durability and functional features without being overly complicated.

The Hayward W3DE3620 ProGrid Diatomaceous Earth DE Pool Filter is designed to provide high efficiency and exceptional water clarity for in-ground pools. With a 36 sq. ft. filter size, it offers substantial filtration capacity, making it suitable for medium to large pools. The high-impact grid elements contribute to efficient filtration and backwashing, ensuring clean and clear pool water.

The durable, glass-reinforced copolymer construction promises longevity and resistance to corrosion, even under harsh weather conditions. Maintenance is user-friendly due to the tamper-proof, one-piece clamp that allows quick access to internal components without disrupting plumbing, and the rapid-release air relief valve simplifies air bleeding from the system.

At 66 pounds, it is relatively heavy and may require assistance during installation. Additionally, the manual air relief valve may require more frequent attention to prevent air buildup. This filter is a solid choice for those seeking durability and high performance, but potential buyers should be prepared for its heft and the need for occasional maintenance checks.
