Removing all the dirt and debris in the water is one way of maintaining the good condition of the pool. With the use of swimming pool filter, eliminating all stubborn dirt and other solid particles in the pool can be easier and convenient.

Pool filter plays a big role in the cleanliness and good condition of the pool. But before you purchase one for your pool, let me discuss first the different types of pool filter and their mechanism.

1. Sand Filter

Sand filter uses a unique type of sand in its filtration system. It works by forcing the water through a tank to the bed of sand where dirt and debris are trapped. The clean water and dirty water are being separated by lateral tubes and then pushed to the sand where all the solid particles are filtered out. Afterwards, the filtered water are sent back to the pool.

2. Diatomaceous Earth Filter (DE Filter)


This pool filter utilizes diatomaceous earth for its filtration system. It constructed with plastic grids laid over a special fabric that effectively sorts out all the unwanted dirt and debris. It works by pushing the water through the fabric where solid particles are filtered out. DE filter has the ability to filter even the smallest particle unlike the sand filter.

3. Cartridge Filter

Among the three types of pool filter, cartridge filter is the cheapest. It has a unique paper filter inside wherein the water is scanned from dirt and debris while passing through it. Unlike the sand and DE filter, cartridge filter cannot filter large-sized debris and dirt. It should also be cleaned regularly to prevent the filter from clogging.
