Pool Filter Media Comparison

ZeoSand vs. Sand, Glass, and Multimedia Filter Media — performance, flow rate, and particle removal compared

Swimming pool filters use several types of media, including silica sand, crushed glass, multimedia blends, and natural zeolite. Performance varies significantly between these options, particularly in particle removal, flow rate, and dirt-holding capacity.

ZeoSand natural zeolite filter media is engineered to replace conventional sand, glass, and multimedia media—delivering finer filtration, higher flow rates, and longer filter cycles.

Which Pool Filter Media Produces the Clearest Pool Water?

The answer depends on filtration efficiency, flow rate, and dirt-holding capacity—key performance factors compared below.

Filter Media Comparison Table

Property ZeoSand Sand Glass Multimedia
Filtration Rating (µm) 2–5 20–40 10–15 10–20
Relative Dirt Capacity ~3× Sand Baseline Moderate Moderate
Flow Rate (gpm/ft²) 8–18 2–5 5–10 3–10
Surface Area (m²/g) 25–30 <0.1 <0.1 ~1–5

Values shown are typical ranges reported in filtration literature and may vary with media size, system design, and operating conditions.

Why ZeoSand works better

High Surface Area Porous Structure Low Bulk Density
Finer Filtration Greater Dirt Capacity Higher Flow Rates

Why ZeoSand Outperforms Sand, Glass, and Multimedia

ZeoSand is a natural zeolite pool filter media that replaces conventional sand, glass media, or multimedia filter media to produce clearer water, longer filter cycles, and improved energy-saving filtration performance.

Finer Particle Removal – Cleaner, Clearer Water
ZeoSand has more than 100 times the surface area of conventional sand. This high surface area allows the media to capture and hold much finer particles, producing noticeably clearer water.

Greater Dirt-Holding Capacity – Longer Filter Cycles
The angular and porous natural zeolite structure stores dirt throughout the depth of the filter bed rather than only on the surface. This allows up to three times greater dirt capacity and longer filter cycles between backwashing.

Higher Flow Rates – Lower Energy Use
ZeoSand’s lower bulk density and angular particle shape create a more open filter bed. Water flows through the media more easily, allowing higher flow rates with lower pressure loss than sand.

Installation and Conversion

ZeoSand natural zeolite filter media installs in most pool filters the same way as conventional sand. Detailed installation and conversion instructions are provided in the ZeoSand Technical Manual in the Technical Library, including recommended media quantities, backwashing procedures, and system startup guidance.
