How to clean the pool filter


Why do you need to clean the pool filter in the first place? It is important to clean the pool filter because this is the way the pool system gets rid of impurities in the water. Filtration is important because it removes contaminants that promote the growth of bacteria and algae.


If you want to know how often or how to clean the pool filter you need to consider a few things like what kind of pool filter you own and how much dirt gets into your swimming pool. For residential swimming pools there are three main types of pool filters: sand filters, cartridge filters and diatomaceous earth filter or DE filter.


The easiest to clean is the sand filter, but you need to take into consideration the pool level because you have to backwash the filter wasting some of the water on your pool. In general, this type of pool filter should be clean once a week.


To clean the cartridge pool filter, the system must be turned off and the suction valve must be closed so you don’t loose the prime of your pump. That’s important because if you loose prime you can generate damage in your pool pump. After you make sure that the pool system is off, you need to open the pool filter and take the cartridge out to clean it. The method to clean the cartridge will depend on its condition. Usually, this type of pool filter can be cleaned every other week.


Finally we have the DE filter. This type of filter uses very special and fine sand made of fossilized exoskeletons of tiny diatoms. It is better you leave the cleaning of DE filters to your pool technician as it requires special handling. The DE filter should be cleaned every 4 to 8 weeks.


Cleaning the pool filter is essential to maintaining your pool in proper condition. It can be costly not to clean your pool filter as the finish or the pump might get damaged.
