Sand Pool Filters

A sand pool filter is the most popular form of pool filtration and the most widely used among pool owners and professionals. This is due mainly because of their versatility and ease of use. They use sand to filter dirt and debris from your pool and reduces particulate down to 40 microns in size. Although not as efficient as de filters or cartridge filters they do a decent job of filtering while being affordable and low maintenance.

Sand water filters are ideal for home swimming pools as well as pools that get used more frequently, such as a public pool in an apartment or a community centre pool. They are more practical in a heavily used pool because of the easy maintenance and longevity of the sand. Once the sand is backwashed it is almost as good as new and this process can be done over and over again. A sand filter is ideal for salt water pool systems because the salt content of the water can actually increase the longevity of the filter sand.

Sand Pool Filter Usage

A sand filter is the most cost effective and easy to use of all the salt water pool filters available on the market. The affordability of sand and the low cost to maintain are two of the main advantages. The main downside is the lower quality of filtration but most pool owners are more than satisfied with the filtration provided by a sand filter. If you want increased filtration quality you may want to consider a cartridge pool filter that doesn't require backwashing or a de pool filter with unmatched filtration capabilities.

With typical use of your pool you will need to run a backwash every two weeks when your pool begins to show signs of cloudiness or murkiness. Another indicator is if the pressure rises to 5 to 10 pounds above normal likely indicating there is too much debris obstructing the flow of water through the filter. If a sand filter backwash is required more frequently that usual you should consider changing the sand.
