In addition to making it possible to swim in transparent, healthy water, the choice of a suitable filtration system is crucial for all of the devices required to maintain a pool to work properly.
When we are in a pool, our bodies absorb large amounts of water through the skin. It is therefore extremely important to reduce dirt and other harmful substances in pools as much as possible. The key piece of equipment for doing so are filtration systems.
There are three types of filter available on the market: sand, cartridge and diatomaceous earth filters. Each have specific advantages and disadvantages, but they basically work in the same way. The pool’s pump forces water through the skimmers and reaches the filter, which traps particles of dirt. Once free of all impurities, the water is returned to the pool.
As mentioned above, the quality of a filter has a direct effect on the rest of a pool’s components. If filtration is optimum, the pressure on the pool floor is kept at suitable levels and the pumps do not undergo excessive wear and tear. Another aspect worth highlighting is that if clean water flows gently throughout the cycle, a smaller amount of chemical products is required for disinfection.
In order for the filtration system to work reliably, it is advisable to wash the filters regularly. Cartridge filters should be washed every week with water at high pressure (tap or hose) and any remaining dirt (if any) removed using a soft brush.
With more than 40 years of experience in the market, AstralPool has now launched its self-cleaning NanoFiber filters. The three models in this range (NanoFiber 150, NanoFiber 180 and NanoFiber 200) are made using nanofibre technology and run on an exclusive operating system that make them a unique product in the market.
Unlike traditional cartridge filters that are able to retain particles of between 20 and 60 microns, the Nanofiber’s filtering agents are able to filter particles of between 5 and 8 microns, which is the same as a diatomaceous earth filter (to give you a clear idea, a grain of table salt has an average size of 100 microns).
