Sta-Rite System 3 Modular D.E. Filter
To enjoy the clearest, cleanest water in your pool, install the Sta-Rite? System3? Mod D.E. pool filter, the latest advance in diatomaceous earth (D.E.) filtration. Diatomaceous earth, a natural substance, is so fine, it traps dirt and debris as small as five microns (1?10 the width of a human hair). That means body oils, suntan lotions, pollens, dust, and even some bacteria are trapped in the filter, leaving behind sparkling clear, healthier water.
