Crystal-clear water starts with the right filter. Your pool or spa filter works around the clock — trapping dirt, debris and contaminants so every swim is in water that sparkles. Whether you're upgrading an ageing system or building new, Aqua Clear stocks a complete range of pool filters and spa filters to suit every pool size, budget and maintenance style.

Why Your Filter Choice Matters

The right filtration doesn't just keep water looking good — it protects your equipment, reduces chemical use and cuts down on cleaning time. A well-matched filter means fewer backwashes, lower running costs and water so clear you'll want to dive straight in.

Sand Filters — The Trusted Classic

Time-tested, reliable and simple to maintain, sand filters use a bed of specially graded sand to trap debris as water passes through. They're a great all-rounder for larger pools and high water volumes, with affordable upfront costs and straightforward servicing. If you want dependable, set-and-forget performance, a sand filter is a solid choice.

Crushed Glass Filters — The Modern Upgrade

Crushed glass (glass media) filters are the new-generation alternative to sand. The sharper, finer glass particles capture smaller debris than sand — delivering superior water clarity, less backwashing and a longer filter media life. It's also an eco-friendly choice, often made from recycled glass. For pool owners who want the best filtration performance available, glass media is hard to beat.

Cartridge Filters — Compact & Low Maintenance

Cartridge filters use pleated fabric cartridges to capture fine particles with minimal fuss — no backwashing required. Simply remove, rinse and reinstall. Their compact footprint makes them ideal for smaller plant areas, spa pools and tight spaces, while delivering excellent water clarity with very little maintenance.
