Savvy pool owners understand the importance of a swimming pool filters is undeniable. Pool filters remove debris and pollutants that cause dirty water cloudy. However, pool filters above ground pools and are important for more than just aesthetic reasons, such as contaminants such as bacteria can cause disease, while the turbid water creates ideal conditions for algae growth.

Three types of filtration systems available for in-ground swimming pools, to decide which system is right for you and your pool may seem confusing. However, filters, pool sand filters, pool cartridge and diatomaceous earth or DE swimming pool filters will all allow you to keep your pool clean and maintained. Understand the pros and cons associated with each different type of filter simply allow you to choose the system that will be most suitable for the pool and your situation.

Pool sand filters are the oldest and most popular type of swimming pool filters above ground. Been used by the owners private pool for many years and are great to keep the water free of dirt and debris. These pool filters feature a number of sections that contain special grade sand pool. As the pool water pump driven through the filtration system, dirt and other debris are trapped in the spaces between the particles of sand. They are therefore unable to move as clean water continues through the sand, coming out through the bottom layer and the return to the pool.

About every couple of weeks, the accumulation of impurities in the sand accumulates to the point where the pressure in the filtration system will begin to rise because the water is having more difficulty passing through the sand clogged. As a result, pool sand filters must be backwashed every so often to keep them functioning effectively. Swimming pool sand filter backwash simply involves reversing the flow of water so the dirt will be put out of the sand bed and can be removed through the waste line.

Sand in swimming pool filters above ground pools are so popular among owners of the pool, because they are simple to use and require relatively little maintenance and attention. Even in the event that a sand filter becomes very dirty and clogged, are easy and fairly inexpensive to replace. On the other hand, some owners like to have a swimming pool to perform the operation manual washing several times during each bathing season. However, the main disadvantage of swimming pool sand filters is that they are the least effective when it comes to removing smaller particles from the water, because they typically can not trap particles smaller than 20 microns.

While the pool filter cartridges are available for many years, their popularity and acceptance only recently begun to enjoy a rapid increase. These filters in the pool for swimming pools above ground and use a cartridge element, similar to that found in a typical kitchen sink, to exclude dirt and other impurities. Often made of reinforced polyester materials, swimming pool cartridge filters have a larger area than the pool filter sand. This means that the filter cartridge clogged less often and therefore require less maintenance. In fact, cartridge filters usually only need to be cleaned once or twice for each bathing season.

Another big advantage of swimming pool filter cartridge above ground pool is the fact that when you need to be cleaned, it is very easy to do. Rather than require washing, the item must simply be removed from the cartridge filter housing and washed down with a hose. While there is nothing cheap cartridges, which can last only one season, there are also elements of more expensive cartridges, which will last at least five years. Regarding the capacity cartridge swimming pool filters to filter impurities, are more effective as sand pool filters can trap particles as small as 10 microns.

The third category of filters for swimming pools above ground consists of diatomaceous earth or DE swimming pool filters. As expected from the name, pool DE filter using diatomaceous earth as filter medium. Derived from the exoskeletons of fossil diatoms, diatomaceous earth is a porous powder with small openings that appear sponges when viewed under a microscope. This powder is used to coat the internal parts of the grid filter, creating a cake of filter that strains of algae, debris and other impurities from water.

In terms of maintenance, pool filters, DE are very similar to sand filters in that they require washing or draining every few weeks to keep them working effectively. The main advantage of using a diatomaceous earth filter for your in-ground swimming pool is that this type of filter filtration offers much better captures the small particle size as 2 to 5 microns.

Therefore, if you want your pool water to be really polished, DE pool filters are a good option. However, keep in mind that all pool filters above will help keep your pool clean and well maintained.
