The Challis Ag+ AquaWave Pro 500 is a compact, cabinet-style reverse osmosis (RO) system engineered for high-demand point-of-use water purification in hospitality, dental, commercial and busy domestic settings. Designed as an all-in-one continuous-flow RO unit, the Pro 500 balances high output with low waste and simple servicing — making it a pragmatic choice where space, reliability and water quality matter.
Key benefits
• High capacity for busy sites — produces up to 400 gallons (≈1,500 litres) of purified water per day, suitable for restaurants, clinics and office water stations. 
• Improved water efficiency — an advanced recovery profile significantly reduces wastewater versus many conventional RO systems, lowering operating costs and environmental impact. 
• Compact, cabinet design — engineered to fit neatly under counters while housing all filtration stages and ancillaries in a single hygienic enclosure, simplifying installation and maintenance. 
• Low maintenance, user-friendly servicing — patented modular filter cartridges and spill-proof replacement design make routine changes quick and hygienic, reducing downtime and operational hassle. 
Core Features
• Five-stage filtration train: pre-sediment, activated carbon(s), high-performance RO membrane, and final carbon post-polish to remove taste, odour, chlorine, heavy metals, pesticides and most dissolved solids. 
• Auto-flush / membrane flush function to preserve membrane life and performance. 
• Low wastewater / high recovery ratio compared with standard RO units, improving sustainability and reducing running costs. 
• Optional booster pump and optional storage tank for installations with low inlet pressure or where peak demand needs buffering.
• Spill-proof cartridge handles and cabinet access for safe, clean filter swaps.
