The Express Water 100 GPD system is a multi-stage under-sink water filtration unit that integrates reverse osmosis, UV sterilization, and alkaline mineralization to remove up to 99.99% of contaminants. It offers comprehensive purification for large households, though the slow flow rate and space requirements are notable trade-offs. It is best suited for large households (8+ people) seeking comprehensive water purification.
The Bluevua RO100ROPOT is a portable countertop reverse osmosis system that offers comprehensive 99.99% contaminant removal with UV sterilization and remineralization. Its main drawbacks are its large footprint on the counter and a wasteful 2:1 water-to-waste ratio. It is ideal for renters or those who cannot install permanent under-sink systems.
