First Rate Swimming Pool Filter Wrench Innovation
The three most common types of swimming pool filters are Cartridge, Sand and Diatomaceous Earth Filters (DE filters). Cartridge pool filters operate using paper to filter debris out of the water. As the name suggests, paper cartridges are installed inside the filter housing. Cartridge filters are easy to maintain and can be cleaned by simply removing the filter medium spraying the filter paltes using a hosepipe. Properly cared for cartridge filters could last for three to five years.
The DE Filter: DE is short for Diatomaceous Earth. DE is an organic powder that is actually mined fossilized exoskeletons of tiny diatoms. Its the most effective filter, getting smaller particles from the water. It filters down to 5 microns. The DE powder is normally put into the skimmer, from which point it is sucked into the DE filter and coats the DE filter grids, which consists of 68 grids in the filter housing. The DE substance then catches the dirt and debris. The amount of DE used is based on the size and specific model of DE filter.

How often do you need to backwash and replace the DE? This depends on the condition of your equipment, how dirty your pool is, and the size of your DE filter. In the peak of the summer this may be every 23 weeks. However, a really dirty pool or a green pool, may need to be backwashed a few times a day until the pool is cleaned. DE Filter Backwashing Tip: Backwash more than once. After you backwash for several minutes, change the value back to filter mode, run for a few minutes, then put in backwash mode again, and more dirty DE will get backwashed out.
Another great advantage of cartridge pool filters for inground swimming pools is the fact that when they do need to be cleaned, its very easy to do so. Rather than requiring backwashing, the cartridge element simply needs to be removed from the filter housing and washed down with a hose. While there are inexpensive cartridge elements available that may only last one season, there are also more expensive cartridge elements which will last at least five years. With respect to the ability of cartridge swimming pool filters to filter out impurities, they are more effective than sand pool filters as they can trap particles as small as 10 microns.
