iSpring RCD100 Countertop Reverse Osmosis System with Hot Water

System: The iSpring RCD100 is a countertop reverse osmosis water dispenser with four temperature options, built-in UV, and plug-in operation. Its hot-water dispensing, filter-life monitor, and claimed 2.5:1 pure-to-drain ratio add convenience, while the reported reliability and filter-durability concerns are worth weighing.

What to know before buying

Listing details to confirm

The listing's 100 gallons in the basic details conflicts in unit and meaning with its 100 GPD title claim. The 1.3-gallon tank and 100 GPD capacity are separate claims, and should not be treated as interchangeable. The listed 65 °F lower temperature and the stated room-temperature option are also not clearly reconciled. Manufacturer filtration and contaminant-reduction figures are claims tied to specified conditions, not guaranteed results. It is intended for city water, not well water, and the tank is for cold water only. Fully empty the tank before refilling, including the separate wastewater section. Hot dispensing requires unlocking the child-safety feature.
