Different types of pool filters

All mechanical items require some vital component that is simply essential to the proper and effective operation of the machine and swimming pools are no exception to the rule. For some curious reason this always takes people by surprise, perhaps they are under the mistaken impression that a swimming pool is little more than an oversized bath! Nothing could be further from the truth, as swimming pools require a great deal of care and commitment so as to ensure that they are kept hygienic and clean at all times. Pool filters are invaluable parts of any swimming pool and because pool filters are specifically responsive for the effective filtering as well as cleaning of the water in the pool it is essential that properly sized pool filters are used.

Another common misconception is that that pool filters will fit any size and type of pool, this is not the case and there is a wide selection and range of pool filters to choose from, the best pool filters will be entirely subjective, contingent upon budget, the size of the pool as well as your own personal requirements. In order to save money and cut corners, some people buy smaller pool filters for large pools thinking these pool filters will be able to do the job. The short answer is no, don't try and cut corners, because you make a major loss in the long run when you have to replace your pool filters more frequently.

The following is a list and breakdown of the most common types of pool filters encountered:

Diatomaceous Earth pool filters are ideal for removing the various bits of debris that so often accumulates in swimming pools, bit of leaves, skin and other very fine particles which are often invisible to the naked eye with the technical specifications of the DE pool filters unrivalled by the other types of pool filters. Best of DE pool filters do not require to be replaced unlike sand or cartridge pool filters, although be aware that DE pool filters operate at very high degrees of pressure so make sure your pool pump is able to safely handle this degree of pressure.

The way DE pool filters work is very simple as they operate as a combination of a sieve and water pump. DE pool filters have a number of porous openings on the surface of them and clean water is passed through the filter and in exchange dirty water which contains the material to be filtered is also passed through the filter. The minute particles will then become trapped as they pass through the filter and these internal elements are coated with the diatomaceous earth, making a filter cake that catches everything from dust, algae, dirt, and some bacteria.

Make sure that you carry out the relevant maintenance of DE pool filters, if the pressure ever exceeds six pounds higher than the normal operating pressure then this will have a major detrimental effect upon the efficiency and power of the DE pool filters. In order to most effectively backwash your DE filter you will need to recoat the filter grids, fortunately DE pool filters are built to last and will only ever require such extensive cleaning about twice a year. When the water is dirty, you may need to change the diatomaceous earth once a day. After the water has been properly cleaned, you should consider changing the earth material once every 30 days. In addition, the grids and filter assembly within a diatomaceous earth filter should be cleaned approximately once a year.

For these reasons, DE pool filters are among the most popular pool filters on the market, given the low maintenance required and the minimal technical ability as well as skill required to be expended, this makes them ideal for novice consumers who have little practical experience with repairs.

Sand pool filters whilst not quite as effective or popular as their earth counterparts, are still heavyweight contenders in the pool filters market and are renowned for their powerful filtering capabilities in terms of speed and volume. Even better, the sand pool filters are exceptionally durable as they require to be replaced every couple of years or so and has remained a firm favourite among consumers, being one of the cheapest, and well known models, sand pool filters are valued by pool owners everywhere. However, whilst they don't need to be replaced that often, they DO require frequent cleaning, and so be prepared to thoroughly clean your sand filter every couple of weeks.

Cartridge filters these types of pool filters are best suited for smaller pools and Jacuzzis, and are the weakest of all the possible pool filters, due to its limited filtering capability and limited life span. Their one saving grace however is that they are quite cheap which helps ease their ineffectiveness a little easier.

Cartridge pool filters also become a nuisance in terms of the amount of maintenance they require, frequent hosing and washing down of the filter is essential to prevent the build up of material and debris. With these sort of pool filters there is a real danger that you get sucked into the vicious cycle of the cartridge not operating effectively due to high levels of debris which means more accumulates. These pool filters do not operate well under high levels of pressure, so make sure you keep a close eye on their capacity and their working efforts.

Regardless of the type of pool filters you use, remember that whilst cleaning is an important element to the long term life span of the filter, establishing a regular cleaning routine will exponentially bolster your chances of success.

So what is the best pool filter overall? sadly, there is no definitive answer to this question, it is entirely subjective, and contingent on your own needs, goals and budget.
