Direct answer: A tankless office filtration system connects to the building water supply and treats water as it moves toward the dispenser. Some dispensers still use internal hot or cold reservoirs, so “tankless” must be defined.
The system may use sediment, carbon, reverse osmosis or other stages depending on the configuration. The building still needs suitable water pressure, connection access, power and possibly drainage.
Follow the water path
Supply water enters through an approved connection, passes through the specified filter stages and reaches the dispensing system. Reverse-osmosis configurations may require a drain and may use storage depending on design.
Clarify reservoir terminology
A provider may call the filtration path tankless while the cooler has temperature reservoirs. Ask for a diagram and the exact model specification so the term does not hide capacity limits.
Confirm building requirements
Review water pressure, line distance, electrical supply, drain needs and maintenance access. Compare plumbed-in water coolers with the installation guide.
