Supports the filter layer firmly and prevents it from breaking during operation. - Filtration performance: Wrinkle ultra-fine pool cleaning filters remove small particles more effectively than non-fake filters, allowing greater removal of dirt and helping keep the pool floor crystal clear. - Filtration capability: Filters capture and remove fine dirt such as leaves, grass, insects, dust, pollen and other floating objects. Prevents debris from reaching and clogging pool pumps and cleaning robots, reducing maintenance requirements for the filtration system. - Use scenarios: - Routine pool maintenance: Use with Dolphin cleaners to maintain a clear pool floor and consistent circulation. - Debris-heavy conditions: Effective during seasons with leaves, pollen, or frequent dust in the water, helping prevent pump and robot clogs. - System protection: Helps extend the life of pumps and cleaning robots by filtering out fine particles before they reach sensitive components.
