What you receive and how it helps

• Seven full grids (18 by 11 inches) plus one partial grid (18 by 9.75 inches) deliver a full 36 sq ft filtration area, ready to refresh your water.
• Compatibility with multiple DE filter models ensures flexible replacement for a wide range of systems.

High-efficiency filtration design

ABS grids are built for use with Diatomaceous Earth powder and can filter particles as small as 2 to 5 microns. This level of filtration helps trap hair, dust, and sand to support clear, inviting water. The design is trusted by millions of pool owners for reliable performance.

Optimized filtration performance

The grid fabric is engineered to prevent DE clumping and reduce water flow resistance. The result is smoother filtration, better flow, and the potential to extend backwash intervals, saving water and time.

Durable construction and easy maintenance

A reinforced center core adds structural strength, while corrosion resistance enhances longevity. For best results, inspect and clean grids every two weeks to keep filtration at peak efficiency.

Industry standards and real-world validation

As a Pool & Hot Tub Alliance member, POOLPURE aligns with widely recognized filtration standards. The line has earned visibility through real training environments and media coverage, underscoring a commitment to reliable water quality.

Practical tips for installation and use

• Measure your old grids before purchasing to ensure a precise fit and avoid returns.
• Keep a spare kit on hand for easy replacements when signs of wear appear.
