What Are The Real Differences Between Sand, Cartridge and DE Pool Filters?

The pool construction is often described as the foundation of every pool, but as we all know a simple foundation is not enough to keep things functioning. This is where the pool equipment comes into play. As we are all aware the water in the pool must circulate through the filtration system in order to remove any traces of impurities (dirt, bodily fluids etc.). During a normal operation of the filter system, the water from the pool flows through one or more floor drains located on the bottom of the pool and through one or more skimmers that draw water from the surface of the pool. In this way the water is kept constantly clean. Pool filters are responsible for the mechanical removal of impurities from the water in the pool and they are an essential part of each pool. Without pool filters it is almost impossible to keep the water in a good condition for more than two weeks. With the advance of technology several different types of pool filters are now available on the market and each of them has its own advantages and disadvantages.

Most of the pool filters are sand filters. These filters have a large tank which is usually filled with quartz sand that can attract dirt in the best way because of its specific texture. Pool filters are mostly made of materials such fiberglass, reinforced polyester etc. During the process of filtration, the dirty water from the pool comes in through the inlet pipe filter, through which the dirty water flows evenly over the entire surface of the filter. While gravity pulls the water down through the sand to the bottom of the filter, sand collects tiny particles of dirt and attracts litter. The filtered water flows out through the outlet of the pipeline which is located at the bottom of the tank. After a while, the accumulated dirt and residues of impurities in the sand slow down the water flow. The pressure of the filter gives us a clear signal that there is an internal blockage in the filter caused by the dirt and that it is time to clean the filter. In order to do that, a person who takes care of the pool should set the 6-way valve on the filter from filter mode to flush mode.

Instead of sand filter, some pool system use cartridge filters. In such filters dirty water is contained in a cartridge that is made from corrugated paper or polyester fabric. In order to clean this system, simply remove the cartridge and rinse it with a regular water hose.  Cartridges usually last for more than 5 months.

According to many experts the so-called DE pool filters are the most efficient filters today. They use a pressure gauge to signify a need for back-washing. With the help of a DE powder the pool is thoroughly cleaned and even microscopic particles are eliminated from the water.

Which of these types of pool filters is best for your depends on your requirements. If you are looking for a lasting solution you can choose the sand filter. If you want to save some money then you should take cartridge filter into consideration. Finally, if you are looking for the safest and most efficient filter you should purchase Diatomaceous Earth (DE) pool filter.
