Intex Recreation Corp. is part of the Inex group of international companies. It has been developing and producing indoor and outdoor recreational products for more than 40 years. Some of its products include aboveground pools, inflatable pools, pool filtration systems, and inflatable toys.

Intex also creates filter cartridges for pool water maintenance. Some types of the Intex cartridge filters have the ability to filter water from salt-water pools.

Intex cartridge filters utilize a technology invented in the 1960s. The cartridge filter is currently the most widely used filtering technology for pool filter systems. Other prevalent filter system technologies include sand filters and diatomaceous earth (DE) filters.

Cartridge filter elements employ a bigger surface to trap dirt and other impurities from pool water, compared to sand filters. Both expensive and low-cost cartridge filters work with less water pressure and backpressure than sand filters. A new or recently cleaned cartridge filter catches large particles at first. It eventually catches finer debris once the pores of the element are obstructed by the larger particles. The element can snag debris as small as 10 microns.

High-pressure water may be used to clean the filter element. These types of filters require cleaning at least 4 times a year, and may last for more than 5 years. Note that a cartridge filter’s ability to clean pool water decreases every time the element is washed. The lifespan of a cartridge filter also depends on the degree and frequency of filtering it does.

Intex is best known for its aboveground pools, which cover a wide range of products for of various sizes for different budgets. There are four product lines to choose from: the Easy Set pool line, oval-frame pools, rectangular-frame pools, and round metal-frame pools. Pools are made from patented Super-Tough sidewall technology, which are made of three layers.
