The filter is perhaps the most essential piece of equipment to the operation of a swimming pool. This system has the important job of keeping the water free of debris which would otherwise accumulate and encourage growth of algae and bacteria that may be harmful. There are several types of pool filtration systems for both inground and above-ground pools which each offer various advantages.
The entire volume of water contained in a swimming pool normally passes through the filter a few times each day. While the exact filtration mechanism can differ from one type to the next, all filters serve the function of accepting pumped in "dirty" water into a barrier which removes particles of debris. The cost, amount of maintenance required, and advantages each provides differ.
Together, the filter and pump work to keep the water clean and clear. The pump forces water into the filter where the impurities are removed, then it returns the clean water back into circulation the pool. A high-quality filtration system will last for many years and can help keep the time and money spent on maintenance and operation down. There are three types of filters: sand, cartridge, and diatomaceous earth or DE filters, all of which can be used with both inground and above-ground pools.
Most common are the sand filters. They work by filtering water through a bed of sand contained within them, which is capable of trapping debris measuring20 microns. Cleaning is easy, all that's needed is to run water through them in the reverse direction. The sand substrate doesn't need replacing for several years in most cases. The fact that they are economically priced and easy to use, makes them a top choice.
Also scoring high in terms of low maintenance, ease of use, and cost, is the cartridge filter. A replaceable cartridge element is responsible for filtering out particles as tiny as 10 to 15 microns in size. They have the advantage of being reasonably priced, and can simply be cleaned out with a garden hose, or using a filter cartridge cleaner. They must be replaced every swimming season in most cases.
Diatomaceous earth or DE filters are super-efficient in that they are capable of removing even tiniest of contaminant particles, 3 to 5 microns in size. The result is very clear water. These filters contain a natural, sedimentary rock, known as DE, which is crushed into powder and acts as an ideal filtering substrate. Although they do cost a bit more and their upkeep requires more effort, these make up for this in their speed and efficiency.
Independent of the type of filter one selects, it is best to ensure that it has a larger capacity than the recommended minimum. This will mean less frequent cleanings are needed. A design with minimal pumping action is also desirable, since this means money saved on the monthly power bill.
Ultimately, it is a matter of personal preference. Users who greatly value having ultra-clear water, will be best served with a DE filter, while those who are more concerned with ease of use, will likely prefer a cartridge or sand filter for its relatively simple maintenance.
