    How Does A Sand Filter Work?

    As pool water is pumped through the filtration system, it's pushed through a filter tank filled with sand where contaminants and debris are caught on the spiky edges of each sand particle. Standard sand used in sand pool filters is capable of filtering contaminants that measure 20 microns and larger. As water continuously flows through the filter, the contaminants trapped between the sand begin to build up — eventually restricting the flow of water, increasing internal pressure, and reducing the filter's efficiency. However, with proper maintenance, a sand filter will continue to keep your pool clear and clean.

    Sand Filter Maintenance:

    While you only need to replace the sand in your pool filter every 5 to 7 years, occasionally you will need to backwash the filter to clear out all the built-up debris. This is an easy cleaning method that simply reverses the flow of water back through the sand filter, flushing debris out to waste. Knowing when to backwash a sand filter is easy. A pressure gauge on the sand filter alerts you when the internal pressure increases and it's time to backwash the filter.

    Sand Filter Advantages & Disadvantages:

    Advantages: Low upfront cost, easy maintenance, and the sand last 5 to 7 years before needing to be changed, filtration efficiency can be boosted with additives or alternative media.

    Disadvantages: 20-micron filtration is the least effective of the three types and backwashing is viewed by some as not environmentally friendly due to water waste.
