Up to now all Intex pools came with a combined pump and paper cartridge filter. The pumps are very good and whilst the paper filters pick out the dirt and debris in the water they need cleaning often and should be replaced from time to time.
In ground pools and the bigger above ground pools have sand filters. Sand filtration is the best and easiest way to filter swimming pool water. The water is pumped in at the top of the filter chamber and pressure from the pump forces the water down through a bed of sand. As the water passes through the sand bed the dirt and debris is left behind in the sand and clean water emerges via lateral pipes with fine slots in at the base of the filter. When the filter needs cleaning the water is pumped the oposite way, the sand “fluidises”, the dirt is lifted out and the dirty water is sent to waste. This is called backwashing. Sand filters can hold much more dirt than paper filters and don’t need washing as frequently.
Whilst there are many pump and filter combinations on the market they are all geared to inground pools with standard 1.5 inch solid pipe fittings. The difficulty always was adapting the fittings on them to work with the Intex pipework. The new Intex sand filter solves these problems because it is made to fit directly on to the non standard pipe fittings that are found on Intex pools. It also comes with adaptors to make it fit all other makes of above ground pool.
The filter is easy to assemble and requires just one 25kg bag of “16-30″ grade filter sand.
If you are looking to replace your paper filter with a sand filter then the Intex sand filter is the obvious choice.
