Sand Filter vs Salt Water System – DIFFERENCES & SIMILARITIES

Spread the love

Swimming pools provide recreation during the warmer months. However, the pool’s water should be filtered for the safety and health of the swimmers.

The difference between sand filter vs water system is many and both do not accomplish the same tasks.

Sand Filter vs Salt Water System

Let’s check out the functions of each:

  • Sand Filters


Sand filters cannot pump or chlorinate water, but they are attached to a basic pool pump for passive filtration. These filters makes use of unique sized sand particles for trapping debris and dirt that pass through the swimming pool’s water pump. As soon as the filter is full of dirt particles, the sand filter will need to be backwashed for the system to function to it’s maximum.

  • Saltwater Pumps


In contrast, salt water pumps make use of salt placed in the water. Thus, eliminating the need for you to place chlorinated packets into a swimming pool.

Additonally, Salt creates a conducive reaction with the water and the result provides the saltwater pump with the ability to generate chlorine from the reaction. The water moves through the pump, and its filter, to actively clean and sanitize the swimming water.

Filtering Considerations

A saltwater pump must function with a saltwater chemistry of 3,000 parts per million of salt, whereas the sand filter only needs a basic, chlorinated swimming pool for filtration. Compared to the saltwater pump, the sand filter is a low-maintenance item.
