![]() While it’s common practice to turnover your pool water at least once per day, this only filters about 60% of the water. Even better if you can buy one larger than the pump. The filter has to be the same size as the pool pump you’re using. Incorrectly sizing it will result in an inadequately cleaned pool, and the filter’s grids will break down faster. The filter you use for your pool needs to be the proper size. Now let’s talk about the most important features to consider when it comes to choosing a diatomaceous earth filter for your swimming pool. You can either backwash or hose them off without having to remove them from the tank. The wider pleat design of these grids allow for easy cleaning.Longer filter cycles and increased flow rate compared to traditional cartridge filters.This filter uses 4 cylindrical grids that resemble a cartridge filter, but are made from a thicker weave of woven polyester. Quad DE filters borrowed the design of quad cartridge filters and put their own unique spin on it. Curved grid DE filters are designed to conserve space inside the tank for water to flow.Straight grid DE filters can provide a more balanced flow inside the tank during both filtering and backwashing, allowing for lower filter pressure and higher flow rate.This reduces the pressure inside the filter, prolonging its cycle times and increasing its lifespan Some grid DE filters have a “bump handle” which allows you to shrug buildup off the grid.Straight grid DE filters use the same type of grid panels as the curved version, except they’re lined up one after the other (like Dominoes). The curved panels come in different sizes and are layered on top of each other. Using the same circular design, this filter has curved, flat grids made from polypropylene material. They all work the same way, with DE powder coating the grid and contaminants sticking to the DE as water passes through the filter.įinger DE filters have a grid system that resembles long vertical fingers, and there can be up to 100 of them arranged in a concentric circle.Ĭurved grid DE filters are the most common DE filter design. There are a few different styles of grid DE filters: finger, curved, and straight. There are two core types of pool DE filters you’ll come across. ![]() Most expensive filter type, averaging $800 to $900.Backwashing produces wastewater, and backwashing a DE filter (or sand filter for that matter) may be prohibited depending on where you live.Deep cleaning the unit is also required once a year. ![]() DE filters need to be disassembled after being backwashed.
