Cartridge filters are common in residential Houston area pools with low bather loads, and their screening ability is better than that of a sand filter (down to 8-12µ particle size can be captured). But while clarity might be better for a while, cartidges tend to get dirty faster, and need to be cleaned. Unlike sand filters with a simple backwash function, cartridge filters must be opened, removed and manually cleaned. It takes time and effort, and it is not a fun job. On top of that, cartridges do not last very long compared to sand. Some need to be replaced more than once a year, depending on how the pool is used and maintained.
Pressure sand filters are sealed vessels, usually about 1/2 to 2/3 full of [what should be] NSF/ANSI-Certified filter sand and, at the bottom of the filter, gravel. Recently, a new type of filter media, crushed glass, has become popular to take the place of sand. Most sand filters are what we call pressure sand, where water is pumped into the top of the sealed filter, and the water pressure pushes water down through the depths of sand and gravel (or glass), and eventually out through the bottom, through openings called laterals.
Diatomaceous Earth (D.E.) Filters
D.E. Filters can capture particles as small as one micron (1µ). These filters have the best screening ability of any pool filter, hands down. Residential D.E. filters use a series of grids, similar to that of a cartridge filter. The difference is, the grids themselves need to be “charged” or coated with a powdered media called diatomaceous earth, or alternatively, perlite. The D.E. or perlite media is pulled into the filter through the skimmer, and coats the outside of the grids. The grids + media become the screening filter that captures just about anything and everything.
