The value of inground swimming pool filters to the educated pool owner is pool filters. These maintain cleanliness of pool water by removing dirt, debris and other substances from the entire system. More than what is visible to the naked eye, bacteria and other contaminants can be contained using inground swimming pool filters.

Questions are raised on which of the three types of inground swimming pool filters filters is the best there is. Sand, cartridge and diatomaceous earth (DE) filters can all do the job of catching undesired particles in your pool. It can be confusing at first but by being equipped with some basic knowledge on these filter systems you will be able to determine what is best for you as a pool owner.

Sand is probably the oldest medium used for inground swimming pool filters. As the filter pump pushes water through a bed of sand, particles are trapped and only allows clear water to flow at the bottom and return to the pool. Maintenance every few weeks is required as sand eventually causes significant pressure drop in water flow. This means that the filter system is already clogged with particles and will need maintenance work called backwashing. Backwashing is simply the reverse cycle of a normal filtration process.

Sand filters will also need to be replaced when sand is eroded due to the wear and tear of constant water flow. You would know that sand is already eroded enough when filtration takes more time to complete because lesser particles are removed each cycle. It is relatively cheap to replace sand and it does not require frequent replacement. What may probably discourage pool owners from using sand for inground swimming pool filters is the frequent labor intensive job of backwashing required each swimming season. In terms of particle size filtered, sand may not be as efficient as a cartridge or DE filter system. In order to be able to filter finer particles, adding flocculants to the pool can create bigger particles from smaller ones would help.

Cartridges have gained popularity among inground swimming pool filters because of ease in maintenance. These can also be cleaned but it does not require that frequently. Cleaning of cartridges only needs to be done two or three times at the most in a swimming season. You would only need a garden hose for washing off of loose particles and filter cleaning solution and a bucket to soak cartridges in. Once these two steps are done, the last step is to rinse away the cleaning solution and any loose particles left after soaking. A cheap cartridge will last for a season. A fairly high priced and good quality cartridge can last up to five years. Regardless of cost, cartridge filters can catch finer particles than sand.
