Sand Filters
Sand filters are a common choice for pool filtration because they are durable and easy to maintain. They work by passing water through a tank filled with sand, which traps dirt and debris. These filters can catch particles as small as 35 microns. Backwashing reverses the water flow to flush out trapped dirt. These filters are great for large pools because they handle high water volumes well. Despite this, they are affordable and require minimal upkeep. Their simplicity makes them a popular choice for residential and commercial swimming pools.
Cartridge Filters
Cartridge filters offer better filtration than sand filters, trapping particles as small as 15 microns. They use polyester cartridges to catch dirt and debris as water flows through. Unlike sand filters, they don’t require backwashing, which saves water. These filters provide clearer water and are ideal for residential pools or those needing fine filtration. They take up less space and are easier to install. Their eco-friendly design makes them a great choice for water-conscious pool owners.
