Express Water 1 Year RO System Filter Set - 11 Filters, 100 GPD

In this review of the Express Water 1 Year Reverse Osmosis System Filter Set, the bottom line is simple: this replacement kit is meant for households that want reliably clean drinking water without ongoing fuss. The set includes 11 replacement filters plus a 100 GPD RO membrane and is aimed at users who already own a compatible under-sink RO system and want an all-in-one annual maintenance pack. The single biggest reason to buy is comprehensive, staged filtration that targets dissolved solids, chlorine taste, VOCs and microplastics so water tastes noticeably cleaner and safer.

Key Features

• Complete 1 year set: Eleven filters and a 100 GPD RO membrane provide a full annual replacement cycle so users can maintain peak performance without mixing filter types.
• High impurity reduction: The reverse osmosis membrane is designed with density graded layers to reduce dissolved solids, microplastics, fluoride and heavy metals for cleaner water.
• Carbon protection: Activated carbon block and granular activated carbon pre-filters protect the system from chlorine damage and reduce VOCs to improve taste and odor.
• Balanced output: The inclusion of alkaline and post-filters helps restore mineral balance and delivers a better tasting final output after RO purification.
• Size compatibility: The filters are 10 in replacements that fit standard under-sink RO housings for straightforward swaps.

Who It's For

This kit suits homeowners and families with an existing Express Water or compatible under-sink reverse osmosis system who want a single purchase that covers a year of maintenance. It's also a good fit for people who prefer replacing all stages together to ensure consistent water quality rather than buying filters piecemeal.

It is not aimed at users who need a replacement for nonstandard-sized filters or a different flow rate membrane, or those who prefer single-filter specialty cartridges; professionals with custom commercial systems may need different capacities or configurations.

Pros & Cons

Cons
