The choice of filtration mode is directly linked to the requirements of your pool. The size of your pool, how many months you use it per year and the quality of the water can all contribute to making a more informed decision. Finally, your budget is also a decisive factor when choosing a filter.
Available filter types
There are three main types of pool filters, sand filters, cartridge filters and diatomaceous earth filters. The type of pool you have may dictate the type of filter you will need to use.
Sand filters
Although not commonly used in spas, sand filters are the most popular type of pool filter. The way they work is simple, they are filled about three-quarters full with controlled- granulometry pool sand and pumped of water by the pool pump. As the water passes through the sand it is purified of any unwanted particles before they return to the pool. Due to this process, it is necessary to change the filter sand regularly to maintain optimum and effective filtration.
