Top quality Filters from PoolPlaza Pool Supplies

Pac Fab Filters, Sta-rite, and Hayward Pool Filters

Choosing a new pool filter can be a very confusing task.  After all, there are so many different types and sizes and brands of filters and you don't want to make a mistake.

Our filter selection guidelines will steer you to the units that are best suited to your pool and its equipment.

How do filters work?

The pool filter is what removes the fine particulate from the water and enables you to swim in a clean clear pool. 

There are three basic types of filters: Sand, Diatomaceous Earth and Cartridge. Our technicians are experienced in the service and repair of all types of pool filters and backwash valves.

Be sure to check out the links to the left for maintenance schedules, product reviews, product pricing and troubleshooting help.

SAND FILTERS

Sand filters use a specially graded sand as the filter media. The water enters the tank through the diffuser.  As the water goes down through the bed of sand, the dirt and debris is trapped between the grains of sand.  When the water reaches the bottom of the filter, it enters the laterals and is returned to the pool.

Sand filters filter out debris down to about 40 microns in size.  Anything smaller than 40 microns will probably not be filtered out.

How Sand Filters work.
DE Filters - the best Filtration available. DE FILTERS

DE filters use diatomaceous earth as a filter media.  The DE filter has plastic grids covered with a plastic type of fabric.  A layer of filter powder called Diatomaceous Earth covers the grids and does the filtering.

As the water passes through the filter powder, any debris down to 5-8 microns is filtered out.  Because the DE is much finer that sand, it is able to filter much more finely than a sand filter.

CARTRIDGE FILTERS (also sold as Modular Media)

Cartridge filters use a paper-type cartridge as the filter media.  They do not filter as finely as DE, and in our experience produce about the same water quality as sand filtration.

Cartridge filters used to have a bad reputation as a nuisance to maintain, but manufacturers have come up with newer filters with enough surface area (300-500 square feet) to need cleaning only once or twice each year.  This makes the maintenance issue a plus with these filters.
