# iSpring DS4B-MAX Bottleless Water Cooler, 4-Stage Filtration

Filtration: The iSpring DS4B-MAX bottleless water cooler connects to a water supply and dispenses hot, cold, or room-temperature water through a four-stage filter system. Its listing claims SGS testing of the first three filter stages and up to 99% reduction of PFAS, lead, and chloramine. Those are manufacturer claims, not independently verified performance results.

## Before you buy

- The listing claims up to 99% reduction of PFAS, lead, and chloramine and SGS testing of the first three filter stages, but provides no test protocol or conditions here. The stated up-to-12-month filter lives are maximums, not guaranteed intervals. A water-line connection is required.

## A good fit for

- Homes or offices that want hot, cold, and room-temperature water from a bottleless dispenser.
- Buyers prepared to connect the unit to a water supply and maintain four replacement filters.
- People seeking a floor-standing dispenser with a hot-water safety lock and self-cleaning function.

## Less suited to

- Buyers who need a countertop or easily portable dispenser.
- Those who cannot connect a dispenser to a water supply or do not want to replace multiple filters.

## Customer feedback

The supplied evidence contains only aggregate ratings, with a small number of ratings all in the five-star category. That is a limited signal and does not establish why customers rated it highly or how it performs. Consider the water-line connection and the need to maintain four filters when deciding whether its bottleless setup fits your use.
