Pool Filters

Pool Filter Systems Comparison Guide

Pool filters are devices that are specially created for water purification in the pool and for keeping it clean for a long time. Water in pool should be cleared out daily 2-3 times, regardless of whether it was bathed in it or not. The principle of the pool filter is quite simple: by using the filter, contaminated water from the pool is passed through the water intakes and passes through the filter unit. After this cleaned water gets back to the pool. The degree of cleaning depends on the type of pool filter used and the speed of filtration. At a lower cleaning speed, a better purification of the liquid occurs. There are several types of pool filter. The sand filter does not differ in structural complexity: the water in it is cleaned with fine calcined quartz sand.

This is actually an ordinary tank with filler, in which water is supplied by a pump. It is possible to install a multilayer pool filter made of gravel, quartz sand and carbon-anthracite. There are also variations of pool filters with glass and silver sands in the filters. Sand cleaning of water is the fastest. The cost of such a filter is low, but its disadvantage is size and weight, therefore such models are used mainly for water filtration in stationary public pools. The cartridge filter contains propylene membranes as filter elements. They require frequent flushing and replacement, but are inexpensive, so in case of clogging or breakage, they are easily replaced.

Filter cartridges, in contrast to sand filters, are small in size; such pool filters can be installed outside the pool and disguised so as not to spoil the appearance. When choosing such an installation, the main criterion is the volume of water passed per hour (filter performance). This parameter is indicated by the manufacturer in the instructions or on the packaging. Diatomaceous filter is the most expensive, but also the best filter for the pool. It consists of several cartridges. The filter medium inside this device is diatomaceous earth (microscopic particles of the skeletal mass of fossils). The presence of several cartridges provides a high degree of purification: the declared fineness of cleaning is several micrometers. Such filtering plants neutralize most microbes.
