Our point-of-use systems connect directly to your existing water line and use advanced multi-stage filtration to deliver unlimited pure, great-tasting water for your team—all for one simple monthly rate starting at $30.
BWS offers both Reverse Osmosis (RO) and Ultrafiltration (UF) systems to match your water quality needs. RO systems provide maximum purification—removing 99%+ of contaminants including PFAS, lead, chlorine, and dissolved solids—making them ideal for medical offices or areas with poor water quality. UF systems deliver excellent filtration (95-97% removal) while retaining healthy minerals, require no drain line, and offer faster flow rates—perfect for high-volume offices and break rooms.
Whether you need a space-saving countertop unit for a small office (1-15 employees), a high-capacity freestanding cooler for medium offices (16-50 employees), or a water & ice combo for busy break rooms, BWS has the perfect solution. Browse 12 systems below and use our interactive comparison tool to find your ideal match.
Every BWS water cooler includes free professional installation, regularly scheduled maintenance visits, lifetime filter replacements, and responsive local service. No setup fees, no long-term contracts, no hidden costs. Trusted by over 800 businesses across Georgia, Alabama, and Tennessee. Try any system free for 7 days with zero commitment.
While some point-of-use water providers rely on basic single-filter systems, BWS understands that truly pure, great-tasting water requires a more thorough approach.
Single-filter systems might improve taste or remove some contaminants, but they can't address the full spectrum of water quality challenges.
That's why every BWS system uses multiple specialized filters working in sequence.
Each filter targets specific contaminants, creating a comprehensive purification process that single-filter systems simply can't match.
Our multi-stage process removes a wide range of contaminants:
Delivering superior water quality you can taste and trust.
We customize filtration based on your specific water challenges.
Unlike one-size-fits-all single filters, we ensure optimal results for your location.
Staged filtration distributes the workload across multiple filters.
This ensures consistent water quality and optimal filter performance over time, preventing any single filter from becoming overwhelmed.
Our multi-stage systems meet or exceed industry standards.
Every component is independently tested and certified for reliable purification you can count on.
