Which type of filter system removes the smallest micron particles?

The diatomaceous earth filter is recognized for its ability to remove the smallest micron particles from pool water. It utilizes a fine powder made from fossilized diatoms, which are algae-like organisms. This powder coats a grid and creates a barrier that effectively traps particles as small as 1 to 3 microns in size, contributing significantly to water clarity and hygiene.

In contrast, other filter types have different efficiencies. Sand filters are effective for larger particles, typically capturing dirt and debris down to about 20-40 microns. Cartridge filters can catch particles in the 10-15 micron range, making them more effective than sand filters but still not as efficient as diatomaceous earth filters. Microfiber filters offer excellent filtration, but they are not as commonly discussed in commercial applications compared to diatomaceous earth filters.

This distinction highlights why the diatomaceous earth filter is the superior option for capturing the smallest particles in water filtration systems.
