Diatomaceous Earth, or DE, filters are nearly twice as efficient as sand filters when it comes to keeping your pool clean. This Hayward pool filter is no exception, using the microscopic pores in diatomaceous earth to capture the smallest particles like dust and pollen, and remove them from your pool.read more
The Hayward extended cycle DE in ground pool filter uses an exclusive “bump” system that recycles DE powder and extends time between filter backwashing, saving hundreds of gallons of water and time. Self-venting and self-cleaning technologies help make this the of the most efficient and best in ground pool filter.

HERE'S HOW IT WORKS!
Perflex® filter use diatomaceous earth filter powder (commonly called D.E.), which will remove particles as small as one micron, and is the most efficient dirt remover known. It will even remove microscopic dust and pollen. Unfiltered water enters through the bottom connection in the filter tank, flows upward through the Flex-Tubes, and returns to the pool via the outlet in the filter head. When the filter is initially started, diatomite filter powder is fed into the system, usually through the skimmer. This is precoating. As the water passes through the Flex-Tubes, the filter powder is automatically deposited on the outside of the Flex-Tubes, forming the working "filter surface". Similarly, dirt in the water is stopped on the surface of the filter powder. Eventually, the accumulated dirt caused the filter pressure to rise and flow to diminish. this is when ordinary filter need backwashing - but not Perflex®. Simply activate the Perflex® "Bump" handle, and within a minute, flow and pressure are back to normal.
