Many of new pool owners are not much familier with Sand Filter so here i am sharing some Info on them.
Maintaining the cleanliness of a pool with a sand filter is generally ideal for pool owners who want a highly thorough filtering system. Pool filters are available in three types: one is sand, and the other two is Diatomaceous Earth (DE), and cartridge. While a cartridge filter will give you the least cleanest water and maintenance, and a DE cartridge will give you the cleanest water with the most maintenance, the pool sand filter will give you results in between. Keep in mind that using a sand filter does require a little extra maintenance.

Where to buy and the cost of pool sand filters
Pool sand filters are readily available at local pool maintenance shops, and online with a variety of reputable vendors. Depending on the size of the filter, how it is mounted, and the manufacturer's reputation for quality, a filter can cost as little as $200 to over $600. Hayward filters are a very popular, highly regarded, and most expensive pool filter brand, but there are other brands such as Sta-Rite and AquaQuik that have adequate quality at lower prices.


How Often Does This Filter To Be Replaced?
Most pool maintenance experts say that a sand bed should be replaced every 5 to 7 years. The gradual loss of efficiency may not be easily noticeable. When the filter is new the grains are rough, which is important to the efficiency of processing clean water. With continued use, the grains lose this rough quality essential to allowing the filter to efficiently process clean water. If your filter requires frequent backwashing, this can be a sign of calcium build-up, "mudballing", or "channeling". Using biguanide chemicals to clean the filter annually prevents the sand from building up from the mixture of the sand and bodily oils.
