Responsible for keeping the entire volume of water in a swimming pool clear and safe to swim in, a filter is one of the most important machines in the operation of a pool. It eliminates dirt and debris which make the water cloudy and can encourage algae and bacteria growth. Both inground and above-ground pools can be equipped with one of several styles of pool filtration systems, each with its own benefits to the user.
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.
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.
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.
Basically, the filter one selects for their pool should reflect their priorities. If the user's primary concern is a simple design which needs minimal maintenance, either a sand or cartridge filter would be suitable. Whereas those who are focused mainly on having the clearest water possible, should go for the DE filter.
