Claryum, Carbon & Microbial Remineralizer Replacements

In this review the reviewer looks at the replacement set of Claryum, Carbon, and Remineralizer cartridges for the Clean Water Machine model AO-US-RO-MB-4000 and why homeowners who want both reverse osmosis purity and restored healthy minerals should consider them. The bottom line: this kit is for people who already own the AO-US-RO-MB-4000 and value a combined approach that removes a broad range of contaminants while returning calcium, magnesium, and potassium to the water. It is also chosen for its IAPMO certification to NSF/ANSI Standards 542, 53, and 401 and straightforward replacement schedule.

Key Features

• Comprehensive filtration: Reduces up to 99% of 90 harmful contaminants including lead, mercury, pesticides, pharmaceuticals, and chlorine for noticeably cleaner water.
• Remineralization: Returns healthy minerals lost during reverse osmosis, restoring calcium, magnesium, and potassium for improved taste and mineral balance.
• Microbial boost: Includes microbial filtration that targets bacteria and viruses, adding an extra layer of protection beyond standard carbon filters.
• Claryum technology: Addresses contaminants you can see, smell, and taste as well as those you cannot, for more confident drinking water.
• Replacement interval: Filters are rated to last 6 months or 365 gallons, making maintenance predictable for under-sink use.
• Standards certified: IAPMO certification to NSF/ANSI 542, 53, and 401 gives independent verification of specific contaminant reduction claims.

Who It's For

This kit is best for owners of the AO-US-RO-MB-4000 who want to maintain an integrated reverse osmosis system that also restores healthy minerals. It suits families and individuals who are concerned about trace contaminants such as lead or pharmaceuticals and who prefer the taste benefits of remineralized water.

It is not for people using SmartFlow systems, as the cartridges are not compatible, nor for those who need filters with longer than six-month intervals or different connector types. Buyers who prioritize lowest possible cost above certification and microbial protection should compare other replacement options.

Pros & Cons

Pros

• Certified contaminant reduction and microbial filtration give a high level of confidence in water quality.
• Remineralization improves taste and replaces electrolytes removed by RO, which is beneficial for daily drinking water.
• Replacement cadence of 6 months or 365 gallons makes maintenance scheduling simple.
• Claryum filtration handles both aesthetic and hard-to-detect contaminants in one product set.

Cons

• Some customers report occasional leakage after installation, so careful fitting and inspection are advisable.
• Not compatible with SmartFlow systems, limiting use to the specified AO-US-RO-MB-4000 model line.
