How well do Pentair DE filters hold up under high-pressure and heavy-debris conditions compared to other filtration types?
Pentair DE filters handle pressure and debris loads extremely well because their internal manifolds, grids, and clamp systems are built to tolerate the higher operating pressures DE filtration naturally runs at. The body and lid are reinforced to prevent flexing, so they maintain efficiency even when debris builds up. Their grid packs stay stable under load, which helps preserve flow and clarity longer between cleanings. With proper backwashing and periodic teardown, they stay structurally reliable for many years.
How do Pentair OEM pool products compare to Non-OEM Pentair pool products?
Pentair OEM pool products meet exact Pentair specifications. As a result, they provide reliable fit and consistent performance. Additionally, materials and quality control meet strict Pentair standards. They offer dependable operation and lasting system integrity.
Non-OEM products cost less. However, material quality and manufacturing precision vary. Compatibility with Pentair systems is not guaranteed. Lifespan and performance may be reduced. Overall, OEM components deliver quality, while non-OEM products, deliver uncertainty.

FAQ
Our expert staff answers customer's most asked questions.
What are the benefits of a DE Filter?
There is a huge benefit to using a DE (Diatomaceous Earth) filter, DE filters have superior filtration, and can trap particles as small as 2-5 microns. This results in exceptionally clear and clean water. This high level of performance is ideal for removing fine debris like pollen and algae. Additionally, this can potentially lead to reduced chemical usage because more contaminants are removed from the water.
How does DE filtration compare to cartridge systems?
The Diatomaceous Earth (DE) filter system offers powerful filtration that captures particles as small as 2–5 microns. It works by coating the filter grids with a fine DE powder, allowing it to trap dirt and debris more effectively than traditional sand or cartridge filters.
Is this an OEM part?
Yes this part is original, from the manufacturer, and contains a manufacturer part number.
