They function by trapping all the debris particles through a large sandy bed that filters them as precisely as 20 microns. The sand filters are not convenient for large debris. Cleaning these types of filters includes a backwashing process. The sand is easy to maintain as it only requires to be replaced every 5 to 7 years, depending on the location of your pool.

Buying Guide

Depending on your preference or what you have in mind for your pool, any Hayward pool filter can do an excellent job. However, most pool experts recommend cartridge filters especially for large pools because they are more precise in the filtration of particles and debris. They also do not require backwashing like their counterparts, the sand filters. However if you are looking for a budget unit and you do not mind very minute particles in your pool you can always go for a sand filter, which is also very good. Similarly, if you want the clearest water in your pool, a D.E filter is also an option. Still, you have to keep in mind the type of pool you own because what works for an in-ground pool may not necessarily work for an above ground pool. You can always seek the opinion of a pool expert before purchasing a filter so that you are sure of the type of filter to go for.
