3 Kinds Of Swimming Pool Filters

One of essential accessories of your swimming pool is the pump and filter. The pump circulates the water in your pool and brings the dirt and debris into your filter that is responsible for removing it before sending it back out into the pool. This is very essential to your pool to keep it health and clean so that you can swim in your pool. There are several things you need to look at when choosing the type of filter that is best for you. There are three kinds of filters the cartridge filter, sand filter and the Diatomaceous Earth filter (DE).

The Cartridge filter uses an actual filter to clean the particles out of the pool water. It can filter out up to 5 to 10 microns size partials. You will know when the filter needs to be either cleaned or replaced when the pressure in the system increases to 8-10psi (pounds per square inch). If you clean the filter and put it back into the system and the pressure is still high then it is time to replace the filter. The cost of the replacement filters tends to be low.

Sand Filters use layers of sand that the pump pushes the swimming pool water through to clean all of the debris and impurities and traps them in the sand. After the cleaning process the pump pushes the pool water back out into the pool. When the pressure in the system increases to about 8-10 psi you will need to run the pump through a backwash to remove the debris. To do this you need to turn the pump off and turn the diverter valve and run the water about 3 minutes till the water is clear. Once you have finished and have turned the diverter back you need to keep the pump off for a few minutes to let the sand settle. The sand needs to be replaced about every two years.

Diatomaceous Earth (DE) Filter uses a white powder mined substance that runs similar to the sand filter. It can remove the tiniest of particles. Once you have done the backwash on the DE you reenergize it by adding more powder to the skimmer. Make sure when you are adding the powder that you watch the water coming back into the pool to make sure that the water is not cloudy. If the water is cloudy the powder is not going where it should and you need to stop and figure out what is wrong.
