Above ground pool filters are the unsung hero of summertime fun in the sun for anyone with an above ground pool. Above pool filters are basically a big stop sign that prevents particles such as pollen, dust, dirt tree bark get through and back in to your swimming pool. Above ground pool filters ensures your pool water is clean, clear and safe to swim in. Whether it’s a sand filter, cartridge filter or DE filter, they all capture small particles and keep them from returning to your pool. In the Swim's above ground pool filter selection features the best above ground filters from top brands like Hayward and Intex. In the Swim carries three different types of above ground pool filters: cartridge filters, sand filters and diatomaceous earth (DE) filters. Cartridge filters tend to be the most popular with above ground pool owners. A heavy-duty, paper-like cartridge sits in the filter case and collects particles in the water. Once in a while you have to clean or replace the filter cartridge, which is rather easy to do. Above ground pool filters like Sand filters and DE filters do the same as cartridge filters, but in a different way. Sand filters use sand to capture dirt and particles, and occasionally you will have to backwash the unit to clear all the debris from the sand. DE filters use a powdered sedimentary rock media that grabs even the smallest (down to 2 microns) particles, highly effective and slightly more costly than other above ground pool filters.
