The Heart of Your Pool’s Circulation System

A crystal-clear pool starts with the right filter. Pool filters remove dirt, debris, and microscopic particles, ensuring your water stays clean, safe, and inviting. Without a reliable filter, sanitizers like chlorine can’t work effectively, leaving swimmers exposed to cloudy water and potential contaminants.

At Benchmark Pool Supply, we carry a full selection of pool filters — including cartridge, sand, and diatomaceous earth (DE) systems — from trusted brands like Pentair®, Hayward®, Jandy®, and Sta-Rite®. Whether you’re looking to replace an aging filter, upgrade to a more efficient system, or simply keep your current one running at its best, we have the solution.

Why Pool Filters Are Essential

• Cleaner Water – Removes debris, oils, and tiny particles.

• Improved Sanitation – Supports chlorine and other sanitizers.

• Safer Swimming – Keeps water free from harmful contaminants.

• Longer Equipment Life – Reduces strain on pumps and heaters.

• Consistent Clarity – Maintains sparkling water with minimal effort.

Types of Pool Filters

1. Cartridge Filters

• Use pleated cartridges to trap dirt and debris.

• Easy to maintain — simply rinse with a hose.

• Energy-efficient, requiring lower pressure to operate.

• Great for small to medium-sized pools.

2. Sand Filters

• Water passes through a bed of sand that traps debris.

• Simple to use with backwashing functionality.

• Long-lasting media that only needs replacing every 5–7 years.

• Ideal for large pools and heavy debris loads.

3. DE (Diatomaceous Earth) Filters

• Provide the finest level of filtration, down to 2–5 microns.

• Use powder-coated grids for superior water clarity.

• Preferred for commercial pools and those needing pristine water.

• Require backwashing and periodic DE powder replacement.

Choosing the Right Pool Filter

• For Easy Maintenance → Cartridge filters are simple and efficient.

• For Large Pools → Sand filters offer reliability and low upkeep.
