Pentair Swimming Pool Filter: Sand, Cartridge and DE Filters
A Pentair swimming pool filter can help you to keep your swimming pool clean by removing all the contaminants and impurities. The different types of Pentair pool filters available today are:
Cartridge Filters
This type of filter uses paper like cartridges, which are usually made of Dacron (polyester) or other polyester material. The cartridges help to screen out the dirt and other unwanted particles. The unclean water flows in the filter through an inlet. The impurities are left outside the cartridge and the water goes inside the cartridge. The filtered water then flows back to the pool through an outlet.
This type of pool filter usually has a large surface area and can trap impurities as small as 10 microns. Moreover, they are very easy to install and maintain. They also get clogged less frequently and can be easily cleaned them with a garden hose.
DE Filters
This is actually a canister, with a network of tubes and a number of plates inside it. The tubes and plates are coated with diatomaceous earth or DE powder, which traps impurities from the water, as it passes through the filter. DE powder is a porous powder, which is produced from the fossilized exoskeletons of diatoms. The powder has very small openings, similar to sponges.
DE filters offer the most effective filtration. They can trap impurities as small as 2 to 5 microns. They require medium maintenance efforts in terms of backwashing after every few weeks and powder replacement every year.
Sand Filters
This type of Pentair swimming pool filter contains a series of chambers filled with special pool grade sand. The sand present in the tank acts as a sieve and traps the unwanted dirt and debris present in the pool water. It can trap impurities as small as 20 microns. You may backwash the filter once a week or once a month to prevent clogging, depending on usage.
