FAQ
Our expert staff answers customer's most asked questions.
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.
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.
