Pool Filters: Keeping Pool Water Clean and Safe for the Whole Family

A swimming pool filter is one of the many pool maintenance tools to keep your swimming pool clear, fresh-looking and safe to use. They are porous materials such as a cloth, sand, or paper, used in straining away particles, dirt, and other kinds of debris coming from water which undergoes the circulation process and is pushed back to the swimming pool as clean water. Circulating the water continuously through these pool filters is necessary to prevent the growth of algae which is an organism that easily grows and lives mainly in water. It is also responsible in trapping microbes and germs which cannot be detected by the normal eye and which will cause many problems in your plumbing system.

There are two parts of a pool filter working together to make an effective entrapment of particles and producing clean water. These are the motor and the pump and the filter itself. The motor and the pump lets the water enter into it and then pushes it back to pass by the filter which in turn does the filtration process. The pool filter is composed of either these three; sand, diatomaceous material or a cartridge. For the sand filter, water is pushed through a sand filter from the top leaving dirty water on it and passes through lateral tubes which exit water to the bottom bringing out clean water. If the filter becomes clogged up due to dirt which accumulated on it, the pressure of water running out of the tubes decreases, thus, the filter is washed in the reverse process and the dirt is dumped in an allotted container or area where it would dry out and mingle with the ground. If the sand becomes really dirty due to continuous usage, it should be disposed and should be replaced.

For the cartridge type of pool filter, water passes through a filter which catches the dirty particles. Cartridges are much better to use than sand because it is wider in capacity to hold dirt while sand can easily clog up and needs to be replaced. Cartridges can last for years depending upon the kind of fiber materials used, thus, lesser pressure is exerted by the pump and more flow is seen at the bottom. This type of filter also limits you to touch them regularly like sand.

Another type of pool filter is the diatomaceous earth (diatomite) or the water polisher. This is a porous and soft rock which has many industrial uses such as in filtration. These are obtained through mining and according to researchers these are the fossilized exoskeletons of tiny diatoms which are a group of algae. They are very small and can filter out smaller particles. They are backwashed like sand but require higher pressure than cartridge pool filter.

Buying a pool filter will depend upon the capacity of your pool but a bigger pool filter that is larger than the pool's capacity is much more preferred for effective and fast cleaning of your swimming pool.
