Crystal-Clear Water Down to 10 Microns

The BLACK + DECKER 425 Inground Quad Cartridge Filter Tank takes pool filtration to the next level. With four large-capacity cartridges working in tandem, this filter captures debris, algae, and particles as small as 10 microns — far finer than sand filtration — so your pool water stays visibly cleaner, longer. No backwashing required, and no sand to replace.

Why Cartridge Beats Sand

• 4-cartridge quad design — massive surface area for superior filtration capacity and longer intervals between cleanings
• Filters to 10 microns — captures fine particles that sand filters miss, including pollen, sunscreen residue, and fine debris
• No backwashing needed — simply remove and rinse cartridges; saves water and reduces chemical loss
• Inground pool rated — built to handle the flow rates and pressure demands of inground pool systems
• Durable tank construction — corrosion-resistant materials designed for long-term outdoor use
