Buying Guide for the Best Intex Pool Sand Filters
Choosing the right sand filter for your pool is an important step in ensuring clear, clean water all season long. Sand filters are a popular choice for both above-ground and some small in-ground pools because of their efficiency, relatively low maintenance, and longevity. When shopping for a sand filter, consider your pool size, your maintenance preferences, and the amount of use your pool gets. Understanding the main features and specifications of sand filters will help you select the right model that suits your needs and makes pool care easy and effective.Filter Flow Rate (GPH or GPM)The filter flow rate indicates how much water the filter can process in an hour (usually measured in gallons per hour, GPH, or gallons per minute, GPM). This is important because your entire pool water should be filtered within about 8 hours for proper cleanliness. Flow rates are typically divided into lower (below 1,500 GPH), medium (1,500–3,000 GPH), and high (over 3,000 GPH) segments. Choosing the correct flow rate depends on your pool’s volume; larger pools need a higher flow rate to properly circulate and clean the water, while smaller pools can use a lower flow rate filter.
Tank Size (Sand Capacity)Sand capacity refers to the amount of sand the filter holds, affecting how well it can capture dirt and debris from the pool water. Small tanks (holding less than 100 pounds of sand) are suitable for small pools, medium (100–200 pounds) for average-size pools, and large tanks (over 200 pounds) are meant for big or heavily used pools. Choose a sand capacity that matches your pool size, as an undersized tank will need to be cleaned more frequently, while an oversized one could be less efficient for a small pool.
Valve Settings/FunctionsValve functions let you control what the filter does, such as filtering, backwashing, rinsing, or recirculating water. Common valve settings include filter, backwash, rinse, waste, recirculate, and closed. Filters with more settings offer greater flexibility and make maintenance easier. If you want a simple, straightforward experience, look for a filter with fewer basic valve positions. If you like being hands-on with maintenance and need different cleaning options, opt for a filter with more settings.
Pump Compatibility and PowerThe filter works in conjunction with a pump, and their compatibility is crucial. Pump power is measured in horsepower (HP), and it determines how strong the water circulation will be. For smaller pools, a lower HP pump (0.25–0.5 HP) is often enough, while larger pools need more powerful pumps (0.75–1.5 HP). Always match your sand filter’s recommended pump rating and never oversize or undersize drastically, as this can affect cleaning efficiency and equipment longevity.
Maintenance RequirementsDifferent sand filters have varying maintenance needs, from how often you need to backwash (clean out the sand) to how frequently the sand must be replaced. Some filters may need backwashing once every few weeks, while others might require it more (or less) often, depending on pool use and local water conditions. If you want a low-maintenance option, look for filters reputed for long intervals between cleaning and changing sand, making routine care easier for busy owners.
Durability and Material QualityThe build material of both the tank and valve affects how long your filter will last and how well it handles exposure to sun and pool chemicals. Filters made from high-quality, corrosion-resistant plastics tend to last longer and need fewer repairs. To pick the right one for you, consider your local climate and how much direct sunlight or harsh weather your equipment will face—choose the most durable option you can for the best long-term reliability.
