Reverse Osmosis Alkaline UV Water Filtration System - 100 GPD

In this review of the Express Water Reverse Osmosis Alkaline Ultraviolet Water Filtration System, the bottom line is simple: this under-sink system is best for households that want near-complete contaminant removal plus added minerals and UV sterilization in one unit. The reviewer found the 11-stage approach - combining six stages of RO filtration with five stages of mineralization and a UV-C sterilizer - delivers noticeably improved taste and peace of mind about microorganisms. Installation is manageable for a competent DIYer and the included leak detector adds a useful safety layer.

Key Features

• Reverse osmosis filtration: Removes up to 99.99% of contaminants such as lead, chlorine, fluoride, nitrates, calcium, and arsenic to improve water safety and taste.
• Powerful UV sterilization: The UV-C stage targets coliform, E. Coli, viruses and other microorganisms so treated water is free from living impurities.
• Alkaline mineralization: Active Mineral Technology adds calcium, potassium and magnesium back into the water to improve flavor and support daily mineral intake.
• Automatic tank refill: The system fills its storage tank automatically so there is no manual refilling or activation required.
• Leak detection: An emergency leak stop detector is included to shut off water flow if moisture is detected, helping prevent under-sink damage.
• One-year warranty: The system is backed by a one-year warranty for added confidence in build quality and support.

Who It's For

This system is aimed at homeowners and renters who want a comprehensive under-sink solution that removes a broad range of chemical contaminants while restoring healthy minerals. It is especially suitable for families concerned about microbial contamination and for people who prefer water that tastes better than typical tap or bottled options.

Those who should look elsewhere include users who need a countertop or portable unit, people unwilling to perform a DIY installation, or households with very low water pressure where a booster pump would be required. Also, if space under the sink is extremely tight, a different compact system may be a better fit.

Pros & Cons

Pros

• Comprehensive contaminant removal combined with remineralization improves both safety and taste.
• UV sterilization provides an extra layer of protection against bacteria and viruses.
• Easy-to-follow design makes installation achievable by most DIYers and maintenance uses replaceable filters.
• Leak detection feature reduces risk of unnoticed water damage under the sink.

Cons

• Some users report mixed experiences with faucet dripping or minor leakage that may require adjustment.
• Under-sink footprint and multi-stage plumbing may be more than needed for those wanting a minimalist countertop solution.
