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 basic function of a filter, regardless of its design, is to rid the water of impurities so it stays clear and does not pose a threat to the health of the swimmers. All filter types operate on the principle of using a barrier of some sort to physically remove debris from the water. These different models differ from each other in price, upkeep, and in the advantages they provide.
What is referred to as the filtration "system" includes both the filter itself and the pump. The latter pulls water from the pool into the former, where contaminants are filtered out, then the clean water is pumped back into the pool. Well-made systems can last for years, and ultimately they will help reduce the time and money one spends on the pool's upkeep.The basic types of filters are the cartridge, sand, and diatomaceous earth (DE) models, which are all compatible with inground and above-ground pools.
Sand filters are the most common type. Water is filtered through a sand bed inside the filter which traps debris with a size of 20 microns. They are easily cleaned by simply running water through them in the opposite direction, and the sand can be used for several years before it will need to be replaced. Affordable and easy to operate, they are a popular choice with many who own pools.
Another simple to use, low-maintenance, affordable option is the cartridge filter. Capable of filtering particles as small as 10 to 15 microns in size, this method uses a replaceable cartridge element for keeping the water clean. Cleaning is easy and can be accomplished with either a garden hose or with a filter cartridge cleaner product. Normally they should be replaced each swimming season.
DE or diatomaceous earth filter systems offer the ultimate in speed and efficiency. They can eliminate the very smallest particles of debris which are only 3 to 5 microns in size, and work quickly to produce crystal clear water. The substrate contained within them, known as diatomaceous earth, is a porous, natural rock sediment which has been ground into powder. While typically more expensive, this approach does offer superior results.
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.
