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.
