DEV Diatomaceous Earth
Nature’s Water Polisher
Diatomaceous earth is a natural, eco-friendly water polisher. Made of tiny fossil exoskeletons, diatomaceous earth is a safe and natural water polisher. The DEV filter traps debris as small as 5 microns, returning highly filtered water to your pool.
DEV filters have a curved grid design that creates balanced water flow throughout the filter tank, and are constructed with a heavy-duty, durable composite body made of corrosion- and UV-resistant materials.
