Top 3 Best DE Pool Filters of 2025

Maintenance is the center stage of owning a swimming pool. It requires uncountable water testing and topping pounds of chlorine to purify the pool water. But every pool needs a pool filter to capture the waste the chlorine kills. 

And DE pool filters come into play to capture smaller particles for optimum pool filtration. Compared to other filter types, it can trap the tiniest speck of dirt. 

Here in this round-up guide, we reviewed the three best DE pool filters in the market. Therefore, we end this article with an in-depth buying guide so that you can choose the right one for your bucks. 

Types Of Pool Filters

You can find the three following pool filters in the market. Each of them has upsides and downsides. So, read on to know all about them and learn why the DE pool filter is the best despite its high price range. 

Sand Filter

A sand filter is one of the oldest and least expensive pool filters on the market. It has a filtration tank filled with sand. As the water passes through, it captures dirt and particles measure 20 microns or larger. 

You can find two types of sand filters, including top-mounted and side-mounted filters. A top-mounted sand filter is less expensive, and it requires less space. On the other hand, a side-mounted sand filter is easy to maintain. 

The advantage of a sand filter is that it requires less maintenance & costs fewer bucks to get. However, sand filters fail to capture small particles, which is a downside. 

Cartridge Filter 

A cartridge filter has a replaceable filter that captures particles when water goes through it. It is more efficient in trapping dirt down to 10 microns. Therefore, cartridge filters are easy to clean. Just pull out the cartridge filters from the unit and wash them with a garden hose. 

DE Filter

Diatomaceous Earth is the full meaning of DE. It works similarly to the sand filter. This pool filter pumps water through the DE filter powder, capturing particles down to 5 microns. The DE pool filter is more efficient than other filters as it can trap smaller particles. However, DE pool filters are more expensive than the other two-filter types and require the most maintenance.
