What is a pool filter?
A pool filter (sand filter/filter housing) is a powerful filtration system that cleans a swimming pool by filling the pool with special sand that traps debris, contaminants, waste, algae, and other contaminants. As water passes through the filter media, the silica sand traps particles, typically 20–40 microns in size. It is redundant because it is easily biodegradable by backwashing, requiring only sand replacement every 3–5 years.

Structure of a Swimming Pool Sand Filter
A swimming pool sand filter consists of three main parts:
The filter body
The body of the sand filter is usually made from composite material combined with fiberglass. The body has high pressure resistance, protecting the product from weather and environmental impacts, etc. Furthermore, the composite material makes the filter durable over a long period.
Swimming pool sand filter valve
A typical sand filter is equipped with a 6-function valve for easy operation:
- Filter: Circulating filtration mode, water flows from top to bottom through the filter sand layers, removing dirt and returning clean water to the pool.
- Backwash: Backwashing mode, water flows from bottom to top, pushing dirt out through the drain valve.
- Rinse: Forward rinsing mode, water flows from top to bottom, helping to remove any remaining dirt after backwashing.
Waste: This mode discharges water directly outside the filter tank, typically used for removing sediment or changing pool water. - Recirculate: This mode stirs the pool water or aerates the treatment chemicals.
Close: This mode closes the valve, used for repairs or maintenance.
Filter media of the pool sand filter
Filter media: Typically consists of natural sand or artificial glass sand, with common particle sizes of 0.5-0.8mm
Advantages of Sand Filters for Swimming Pools
Compared to other water filtration methods, sand filters offer many outstanding advantages such as:
- Sand filters operate in treating water for swimming pools with overflow channels to maintain a stable water level and ensure the water quality in the pool remains clean.
- The circulation system in the sand filter is designed to distribute water evenly around the pool, helping the water filtration process to occur uniformly, ensuring cleaner water after filtration.
- Sand filters can be used for all types of swimming pools, especially large-volume pools.
- Using sand filters saves energy, reduces maintenance effort, saves chemicals for water treatment, and reduces operating costs.
- Sand filters have low repair and replacement costs, and are easy to maintain and repair when needed.
- Sand filters have a long operating lifespan and are durable over time.
