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 water in a swimming pool typically cycles through the filter several times every day. Although the techniques vary from one filter design to the next, they all basically operate by pumping the water through a barrier which traps particles of dirt and such, removing it from the swimming pool. They differ in terms of price, care and maintenance, and in the benefits 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 of all types are the sand filters. This kind features an in-filter sand bed as its filtration site. Particles which are 20 microns in size will be trapped. Cleaning is done by reversing the flow of water through the unit, and generally the sand can be used for several years. They are a popular choice due to their reasonable pricing and easy operation.
Another affordable, low-maintenance alternative is the cartridge filter. The filtering element in this design consists of a removable cartridge which can remove particles as small as 10 to 15 microns. Economical, they have the added advantage of being easy to maintain by using a garden hose or a filter cartridge cleaner to clean them out. In general a new cartridge is needed for each swimming season.
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.
With any filter design, it is a good idea to choose a model with a larger capacity than the minimum indicated for the size of the swimming pool. This will mean one has to spend less time cleaning the system. Also, it's helpful to opt for a set-up with minimal pumping, as this will reduce costs for electricity needed to run it.
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.
