Understanding Pool Filters
Pool filters are crucial components in maintaining clear and clean pool water. They come in various types, each with their own mechanism of action and suitability for different pool sizes and types.
Types of Pool Filters
The choice of pool filtration systems usually falls between three types: sand filters, cartridge filters, and diatomaceous earth (DE) filters.
Sand Filters: These filters use sand as the filtration medium. Pool water is pushed through a bed of sand which captures and holds the debris.
Cartridge Filters: They contain a pleated polyester filter to capture debris. These are known for their lower maintenance and are easier to clean.
DE Filters: These filters use diatomaceous earth, a naturally occurring substance, to filter pool water. They can trap smaller particles compared to sand or cartridge filters.
How Sand Filters Work
A sand filter pumps pool water through a bed of sand, where debris is caught between the sand particles. The clean water then returns back into the pool. Every few years, the sand should be replaced to maintain the filter's efficiency. A sand filter works well for pools of 16 ft and above and has a simple operation.
Sand Filters vs Cartridge and DE Filters
Sand filters are valued for their durability and ease of maintenance, suitable for filtering fine debris and maintaining larger pools. Cartridge filters are more suitable for pools that do not have a heavy load of debris and require less frequent cleaning. DE filters, while providing the highest level of filtration, are also the most maintenance-intensive, and are ideal for those desiring water of crystal clear quality.Filter TypeMaintenance LevelFiltration QualityPool Size SuitabilitySandLowGoodLargeCartridgeMediumBetterMedium to SmallDEHighBestVarious
Each filter has its own sets of pros and cons, with sand filters being a go-to option for economical and low-maintenance needs, cartridge filters offering a balance between easy maintenance and good filtration, and DE filters being chosen for the highest clarity of pool water but requiring more hands-on attention.
Selecting the Right Sand Filter
When choosing a sand filter for a pool, it's essential to match the filter size and type to the pool's requirements, ensuring efficient filtering and clean water.
Sizing for Your Pool
The correct size of a sand filter is crucial for maintaining pool clarity and preventing equipment strain. Filter size is typically proportional to the pool's volume and the desired flow rate. A standard calculation used by pool professionals suggests that the filter should turn over the pool water at least once every 8 to 10 hours. Here's how to determine the appropriate sand filter size:
Flow Rate: Calculate the pool's flow rate, which is measured in gallons per hour (GPH). If you have a pool with a capacity of 20,000 gallons, for instance, and you aim to turn over the water once every 8 hours, you'd require a flow rate of 2,500 GPH (20,000 gallons / 8 hours).
Filter Capacity: Choose a sand filter with a capacity that can handle the calculated flow rate. For a 20,000-gallon pool, a filter that can process at least 2,500 GPH would be appropriate.
Above-Ground vs In-Ground Compatibility
Sand filters differ for above-ground and in-ground pools based on design and plumbing connectivity.
Above-Ground Pools: Filters for above-ground pools typically feature smaller capacities since these pools generally hold fewer gallons. They come with hoses and connections compatible with above-ground pool inlets and outlets.
In-Ground Pools: In-ground pool sand filters are larger, accommodating more significant capacities needed for the typically larger volume of in-ground pools. These filters must match the plumbing infrastructure of in-ground pools, which is more extensive and complex.
Key Features of Top Sand Filters
