10 Best Sand Filters 2025 in the United States

The Hayward W3S270T2 is a 27-inch top-mount sand filter designed to keep your pool water clean and clear. One of its strong points is the efficient multilateral underdrain system, which uses self-cleaning slotted laterals to ensure balanced water flow and easy backwashing. This helps maintain the sand media evenly and makes cleaning the filter less of a hassle. The top diffuser also spreads water evenly over the sand bed, improving filtration performance.

The filter tank is made from a corrosion-proof, rugged polymeric material, so it can handle outdoor weather without rusting or cracking, adding to its durability. It also comes with a large drain valve that makes winterizing or servicing the filter more convenient. The 6-position VariFlo control valve with a simple lever handle gives you easy access to various functions like filtering, backwashing, rinsing, and more, which suits users who want straightforward control.

This Hayward model is a solid choice for pool owners looking for a dependable, easy-to-use sand filter with good durability and convenient valve controls. It suits medium to larger pools and those who want a balance between performance and user-friendly maintenance.

The Intex Sand Filter Pump & Saltwater System is designed for above-ground pools holding up to 15,000 gallons, making it a good fit for medium to large backyard pools. It uses sand as the filter media, which is cost-effective and only needs replacement roughly every five years with proper maintenance. Its flow rate is about 8,140 liters (or 2,650 gallons) per hour, which is strong enough to keep pool water clean and clear efficiently. The multi-function valve allows for six cleaning modes including filter, backwash, and rinse, which helps maintain the system with ease. The included 24-hour digital timer lets you schedule automatic cleaning times up to 12 hours a day, adding convenience and saving you from manual operation.

Also, the HydroAeration Technology improves water circulation and freshness by adding bubbles, enhancing water clarity. The system is made mostly of plastic, so while it is lightweight and portable at 50 pounds, it may not be as durable as metal filters if exposed to harsh conditions long-term. It comes with necessary hoses and safety features like a built-in GFCI power cord, supporting safe and straightforward setup.

The plastic build requires care to avoid cracks or damage, and users should confirm their pool size falls within the recommended range to ensure optimal performance. This Intex sand filter pump offers good cleaning power, ease of use, and affordability, making it a practical option for pool owners who want an effective and low-maintenance filtration system.

The INTEX QX2100 Krystal Clear Sand Filter Pump & Saltwater Systems is designed for above-ground pools up to 8,500 gallons. One of its primary advantages is the use of sand as a filter media, which is cost-effective and only needs replacing every five years with regular maintenance. It offers a 2,100 gallons per minute flow rate, allowing for efficient pool water circulation through six different cleaning functions, including filtering, backwashing, and rinsing.

The built-in 24-hour timer adds convenience by automating the pump's operation, reducing manual intervention for users. This system also features HydroAeration Technology that enhances water clarity and freshness, contributing to a cleaner swimming environment. Included accessories, such as connector hoses and a power cord with GFCI, ensure safety and ease of setup.

However, the unit is relatively heavy, weighing over 50 pounds, and may be cumbersome to maneuver during installation or maintenance. Made of plastic, the durability might be a concern for long-term use compared to metal counterparts. Additionally, it requires a constant power source, limiting its placement options around the pool area. Despite these drawbacks, the INTEX QX2100 is a well-rounded choice for those looking for an effective and low-maintenance sand filter system for their pool, especially given its ability to reduce chemical use and improve water quality.
