Standard sand filtration is great for coarse debris, but it fails to trap particles smaller than 20–40 microns. This leads to cloudy water and oily surfaces. This Pre-Filter is designed to sit directly inside your inflatable pool to catch ultra-fine contaminants before they can reach your filtration sand.

By filling the chamber with a regular filter sponge or aquarium filter floss, you create a powerful micro-barrier that elevates your pool's water clarity.

Inside the housing, an integrated internal grid prevents the filter media from collapsing or being sucked into the hose under vacuum pressure.

💡 Why Do You Need This?

Standard sand filters cannot effectively capture:

• Sunscreen & Body Oils: They bypass the sand and form an oily film on the water. If they reach the sand filter, they coat the sand grains, causing them to clump together and create channels where unfiltered water flows right back into the pool. Filter floss/sponge naturally binds these greases.
• Pollen & Fine Dust: Micro-particles pass right through sand, keeping the water cloudy. This pre-filter traps them at the source.
• Algae Spores & Fine Silt: Captures early-stage organic material, preventing the sand from becoming slimy and losing its efficiency.
