Atlas Filtri DP Duo SANIC 20" x 4.5" PET Antimicrobial Technology Dual Filter Housing with Bracket & Spanner

The Atlas Filtri DP Duo SANIC 20" Big Filter Housing is a high-performance, Italian-made dual-stage water filtration housing ideal for whole-house (POE) or light commercial use. Constructed from PET reinforced with SANIC silver-ion antimicrobial technology, this housing helps inhibit bacterial growth on internal surfaces—keeping your system cleaner for longer and improving hygiene between filter changes.

Designed to hold two 20" x 4.5" Big Blue cartridges, the DP Duo SANIC is suitable for a wide range of sediment, carbon, and specialty filters, offering robust protection against dirt, rust, chlorine, taste, and odour. The dual-stage format allows for multi-layered filtration—commonly sediment followed by carbon—improving water quality throughout the entire home.

The housing includes a wall-mounting bracket and spanner and features 1" BSP threaded ports, making installation fast, reliable, and compatible with standard plumbing systems.
