The Hayward Pool Diatom Filter Model 3620 is more absorbent than conventional sand filters, making the water clearer and clearer, and is common in pools and large projects.
This product is a unique combination of advanced design and engineering for pool water filtration that is highly resistant to corrosion and climate change.
Hayward Pool Diatom Filters come in two Pro-Grid and Perflex series. But the Pro-Grid series filters have higher purification capacities and are used only for pool water purification.
